Abstract
BACKGROUND It is generally believed that hepatitis B virus (HBV) core protein (HBc) dephosphorylation (de-P) is important for viral DNA synthesis and virion secretion. HBV polymerase contains four domains for terminal protein, spacer, reverse transcriptase, and RNase H activities. METHODS HBV Polymerase mutants were transfected into HuH-7 cells and assayed for replication and HBc de-P by the Phos-tag gel analysis. Infection assay was performed by using a HepG2-NTCP-AS2 cell line. RESULTS Here, we show that a novel phosphatase activity responsible for HBc de-P can be mapped to the C-terminal domain of the polymerase overlapping with the RNase H domain. Surprisingly, while HBc de-P is crucial for viral infectivity, it is essential for neither viral DNA synthesis nor virion secretion. The potential origin, significance, and mechanism of this polymerase-associated phosphatase activity are discussed in the context of an electrostatic homeostasis model. The Phos-tag gel analysis revealed an intriguing pattern of "bipolar distribution" of phosphorylated HBc and a de-P HBc doublet. CONCLUSIONS It remains unknown if such a polymerase-associated phosphatase activity can be found in other related biosystems. This polymerase-associated phosphatase activity could be a druggable target in clinical therapy for hepatitis B.

Abstract
AIM This study aimed to assess the effectiveness and safety of tenofovir alafenamide fumarate (TAF) in the prevention of mother-to-child transmission (MTCT) of hepatitis B virus (HBV). METHODS We performed a meta-analysis of studies from the Cochrane Library, PubMed, ClinicalTrials.gov, Web of Science, EMBASE, China National Knowledge Infrastructure (CNKI), China Medical Information Network, and Wanfang databases. The databases were searched from inception to January 7, 2023, for cohort studies and randomized controlled trials (RCTs) comparing the use of TAF antivirals to other antivirals during pregnancy. We combined the data by means of a random-effect DerSimonian-Laird model and risk ratios (RRs) or a random-effect inverse variance model and standardized mean differences (SMDs) to determine the influence on mothers and infants. Our primary outcomes were infant weight, height, head size, birth defects, and Apgar scores. Additionally, we assessed whether newborns tested positive for hepatitis B surface antigen (HBsAg) at birth and at six months of age. The secondary outcomes of our investigation were alterations in levels of HBV deoxyribonucleic acid (DNA), alanine aminotransferase (ALT), total bilirubin (TBIL), blood creatinine, and urine β2-microglobulin (β2-M) in mothers. RESULTS An extensive literature search identified 216 relevant publications; three cohort studies and two RCTs were included in this study. A total of 341 mothers were treated with TAF, and 342 were treated with other antiviral agents. TAF was as effective as other antiviral medications at lowering HBV MTCT rates at birth and at 6 months of age and ALT, TBIL, and HBV DNA levels. Moreover, compared with other antiviral drugs, TAF did not affect infant weight, height, head size, Apgar scores, and birth defects or maternal blood creatinine or β2-M levels. CONCLUSIONS TAF antiviral therapy during pregnancy was found to be safe for both mothers and fetuses.

Abstract
Background and aims In low endemic countries, screening for hepatitis B surface antigen (HBsAg) in migrants is cost-effective in reducing the disease burden of hepatitis B virus (HBV) infections, but linkage to care (LTC) remains a challenge. This study aims to guide future screening initiatives, with 3 objectives: 1. to compare LTC between different ethnic groups screened for HBsAg with point-of-care testing (POCT) in an outreach setting; 2. to estimate the proportion of HBsAg seropositivity for ethnic minorities; and 3. to investigate the association between seropositivity and HBV risk factors. Methods Opportunistic outreach screenings using finger prick HBsAg tests were performed at civic integration programmes between 11/2017 and 09/2022. If an individual tested positive, an appointment was given immediately at the outpatient hepatology clinic for follow-up and confirmation of HBsAg positivity in blood. Dedicated personnel contacted these individuals to motivate them for further LTC, which was defined as being assessed by a hepatologist, a blood test and an abdominal ultrasound. Results A total of 677 people from different ethnicities (Asian, Middle Eastern and African) were serologically screened using POCT. The observed positivity for HBsAg was 3.4 % (95% CI 2.17-5.05, 23/677). Apart from ethnicity and male sex, none of the surveyed HBV risk factors were associated with HBsAg seropositivity. All HBsAg positive individuals were linked to care and assessed by a hepatologist, despite the COVID-19 pandemic increase in time to follow-up of 82 days (95% CI 51-112 days) vs. 24 days (95% CI 5-43 days, p = 0.008)).Among HBV-infected patients, 31.8% (7/22), 100 % (22/22) and 26.1% (6/23) met the criteria for treatment indication, intrafamilial transmission risk and need for hepatocellular carcinoma surveillance, respectively. Conclusion The proportion of HBsAg seropositivity in ethnic minorities was 3.4%. POCT and commitment of dedicated personnel can overcome previously identified barriers resulting in a 100% LTC.

Abstract
Hepatitis B virus (HBV) produces and releases various particle types, including complete virions, subviral particles with envelope proteins, and naked capsids. Recent studies demonstrate that HBV exploits distinct intracellular membrane trafficking pathways, including the endosomal vesicle trafficking and autophagy pathway, to assemble and release viral and subviral particles. Herein, we summarize the findings about the distinct roles of autophagy and endosomal membrane trafficking and the interaction of both pathways in HBV replication, assembly, and release.

Abstract
Chronic hepatitis B virus (HBV) infection remains a major public health concern globally, and T cell responses are widely believed to play a pivotal role in mediating HBV clearance. Accordingly, research on the characteristics of HBV-specific T cell responses, from activation to exhaustion, has advanced rapidly. Here, we summarize recent developments in characterizing T cell immunity in HBV infection by reviewing basic and clinical research published in the last five years. We provide a comprehensive summary of the mechanisms that induce effective anti-HBV T cell immunity, as well as the latest developments in understanding T cell dysfunction in chronic HBV infection. Furthermore, we briefly discuss current novel treatment strategies aimed at restoring anti-HBV T cell responses.

Abstract
BACKGROUND & AIMS Chronic hepatitis B is a global public health problem, and coinfection with hepatitis delta virus (HDV) worsens disease outcome. Here, we describe a hepatitis B virus (HBV) surface antigen (HBsAg)-targeting monoclonal antibody (mAb) with the potential to treat chronic hepatitis B and chronic hepatitis D. METHODS HBsAg-specific mAbs were isolated from memory B cells of HBV vaccinated individuals. In vitro neutralization was determined against HBV and HDV enveloped with HBsAg representing eight HBV genotypes. Human liver-chimeric mice were treated twice weekly with a candidate mAb starting 3 weeks post HBV inoculation (spreading phase) or during stable HBV or HBV/HDV coinfection (chronic phase). RESULTS From a panel of human anti-HBs mAbs, VIR-3434 was selected and engineered for pre-clinical development. VIR-3434 targets a conserved, conformational epitope within the antigenic loop of HBsAg and neutralized HBV and HDV infection with higher potency than hepatitis B immunoglobulins in vitro. Neutralization was pan-genotypic against strains representative of HBV genotypes A-H. In the spreading phase of HBV infection in human liver-chimeric mice, a parental mAb of VIR-3434 (HBC34) prevented HBV dissemination and the increase in intrahepatic HBV RNA and covalently closed circular DNA. In the chronic phase of HBV infection or co-infection with HDV, HBC34 treatment decreased circulating HBsAg by >1 log and HDV RNA by >2 logs. CONCLUSIONS The potently neutralizing anti-HBs mAb VIR-3434 reduces circulating HBsAg and HBV/HDV viremia in human liver-chimeric mice. VIR-3434 is currently in clinical development for treatment of patients with chronic hepatitis B or D. IMPACT AND IMPLICATIONS Chronic infection with hepatitis B virus and co-infection with hepatitis D virus place approximately 290 million individuals worldwide at risk of severe liver disease and cancer. Available treatments result in low rates of functional cure or require lifelong therapy that does not eliminate the risk of liver disease. We isolated and characterized a potent human antibody that neutralizes hepatitis B and D viruses and reduces infection in a mouse model. This antibody could provide a new treatment for patients with chronic hepatitis B and D.

Abstract
OBJECTIVE Chronic hepatitis B (CHB) and metabolic dysfunction-associated fatty liver disease (MAFLD) are the leading causes of hepatocellular carcinoma (HCC). We aim to explore the impact of concurrent MAFLD on the risk of HCC in CHB. METHODS Patients with CHB were consecutively recruited from 2006 to 2021. MAFLD was defined by steatosis and either obesity, diabetes mellitus, or other metabolic abnormalities. The cumulative incidence of HCC and associated factors were compared between the MAFLD and non-MAFLD groups. RESULTS 10,546 treatment-naïve CHB patients were included with a median follow-up of 5.1 years. CHB patients with MAFLD (n = 2212) had fewer hepatitis B e antigen (HBeAg)-positivity, lower HBV DNA levels, and Fibrosis-4 index compared with the non-MAFLD group (n = 8334). MAFLD was independently associated with a 58% reduced risk of HCC (adjusted hazard ratio [aHR] 0.42, 95% confidence interval [CI] 0.25-0.68, p < 0.001). Furthermore, steatosis and metabolic dysfunction had distinct effects on HCC. Steatosis was protective against HCC (aHR 0.45, 95% CI 0.30-0.67, p < 0.001), while a greater burden of metabolic dysfunction increased the risk (aHR 1.40 per dysfunction increase, 95% CI 1.19-1.66, p < 0.001). The protective effect of MAFLD was further confirmed in analysis with inverse probability of treatment weighting (IPTW), patients who had undergone antiviral therapy, those with probable MAFLD, and after multiple imputation for missing data. CONCLUSIONS Concurrent hepatic steatosis is independently associated with a lower risk of HCC, whereas the increasing burden of metabolic dysfunction aggravates the risk of HCC in untreated CHB patients.

Abstract
Globally, a chronic-hepatitis B virus (HBV) infection is the leading cause of hepatocellular carcinoma (HCC). The transcription factor hypoxia-inducible factor 1 (HIF1) is often elevated in HCC, including HBV-associated HCC. Previous studies have suggested that the expression of the HIF1 subunit, HIF1α, is elevated in HBV-infected hepatocytes; however, whether HIF1 activity affects the HBV lifecycle has not been fully explored. We used a liver-derived cell line and ex vivo cultured primary hepatocytes as models to determine how HIF1 affects the HBV lifecycle. We observed that HIF1 elevates HBV RNA transcript levels, core protein levels, core protein localization to the cytoplasm, and HBV genome replication. Attenuating the transcription activity of HIF1 blocked HIF1-mediated effects on the HBV lifecycle. Our studies show that HIF1 regulates various stages of the HBV lifecycle in hepatocytes and could be a therapeutic target for blocking HBV replication and the development of HBV-associated diseases.

Abstract
The Orthohepadnavirus genus includes hepatitis B virus (HBV) that can cause chronic hepatitis and hepatocarcinoma in humans. Recently, a novel hepadnavirus in cats, domestic cat hepadnavirus (DCH), was identified that is genetically close to HBV. DCH infection is associated with chronic hepatitis in cats, suggesting a similarity with HBV pathogenesis and the potential to use DCH as a novel animal model for HBV research. HBV is shown to use the sodium/bile acid cotransporter (NTCP) as a major cell entry receptor, but the equivalent receptor for DCH remains unknown. Here we sought to identify the entry receptor for DCH. HBV- and DCH-derived preS1 peptides efficiently bound to both human and cat NTCPs, and residue 158 of NTCP proteins determined the species-specific binding of the DCH preS1 peptide. Myrcludex B, an HBV entry inhibitor, blocked the binding of the DCH preS1 peptide. Thus, DCH and HBV may share cell entry molecules, suggesting a possibility of inter-species transmission. Furthermore, our study suggests that DCH can be useful as a novel model for HBV research.

Abstract
Introduction The seeds of Brucea javanica (L.) Merr. (BJ) have been traditionally used to treat various types of cancers for many years in China. In this study, we systematically investigated a BJ oil emulsion (BJOE) produced from BJ seeds with the purpose of evaluating its antiviral effect against hepatitis B virus (HBV). Methods HepG2.215 (a wild-type HBV cell line), HepG2, and Huh7, transfected with wildtype (WT) or lamivudine-resistance mutant (LMV-MT) HBV replicon plasmids, were treated with different doses of BJOE and then used for pharmacodynamic evaluation. Cell viability was determined using CCK8 assay. The levels of HBsAg/HBeAg in cell cultured supernatant, HBcAg in cell lysis solution, and HBV DNA in both were evaluated. Results BJOE at ≤5 mg/ml was nontoxic to carcinoma cell lines, but could significantly inhibit WT/LMV-MT HBV replication and HBs/e/c antigen expression in a dose-dependent manner by upregulating interleukin-6 (IL-6), demonstrating that it possesses moderate anti-HBV activity. As one of the major components of BJOE, bruceine B was found to play a dominant role in IL-6 induction and HBV inhibition. Discussion Our results demonstrated that BJOE suppressed HBV replication by stimulating IL-6, indicating that it has promising clinical therapeutic potential for both WT and LMV-MT HBV.

Abstract
Background Whether viral hepatitis increases the risk of cholangiocarcinoma (CCA) has been controversial. The reasons for the differences between previous research results may be related to the differences in sample size, region, living environment and course of disease. A meta-analysis is needed to clarify the correlation between them and select the key population for early screening of CCA. Meta-analysis was used to explore the relationship between viral hepatitis and the risk of CCA, so as to provide evidence for the prevention and treatment of CCA. Methods We systematically searched EmBase, SinoMed, PubMed, Web of Science China National Knowledge Infrastructure, and Wanfang databases. The quality of the included literature was evaluated using the Newcastle Ottawa Scale. Before merging the effect quantities, the data was first subjected to heterogeneity testing. Heterogeneity testing was evaluated using I2 (the proportion of heterogeneity variation to overall variation). Subgroup analysis was used to identify sources of heterogeneity in this study. The effect odds ratio (OR) of various studies was extracted or calculated for consolidation. Beta's rank correlation, Egger's Law of Return and funnel plot were used to test publication bias. Conduct subgroup analysis based on the regions included in the literature. Results A total of 2,113 articles were retrieved, and a total of 38 articles were included in the meta-analysis. There are 29 case-control studies and 9 Cohort study, including 333,836 cases and 4,042,509 controls. The combined risk estimate of all studies showed a statistically significant increased risk of CCA, extrahepatitis and intrahepatitis incidence with hepatitis B virus (HBV) infection (OR =1.75, OR =1.49, and OR =2.46, respectively). The combined risk estimate of all studies showed a statistically significant increased risk of CCA, extrahepatitis and intrahepatitis incidence with hepatitis C virus (HCV) infection (OR =1.45, OR =2.00, and OR =2.81, respectively). The research points of HCV and CCA were asymmetric, indicating that there may be publication bias in the study of HCV and CCA. Conclusions HBV and HCV infection could increase the risk of CCA. Therefore, in clinical practice, attention should be paid to CCA screening and early prevention of HBV and HCV infected patients.

Abstract
The hepatitis B virus (HBV) infection has a wide range, from fulminant hepatitis to inactive chronic hepatitis B (ICB) infection. The present study evaluated critical factors in the outcomes of HBV infection in a highly endemic region of Iran (approximately 12% HBV positive). The expression of seven genes involved in host immunity (Foxp3, T-bet, ROR-γt, AKT, CREB, IL-28/or IFN-λ2, and IL-28R) and HBx for viral activities were evaluated using real-time PCR, TaqMan method. A total of 58 subjects were randomly chosen, including 28 ICB and 30 healthy controls (HCs) from the Esfandiar district, South Khorasan province, Iran. The expression index of Foxp3 and ROR-γt was moderately up-regulated in ICBs but did not statistically significant. T-bet expression in ICB patients was significantly higher than in HCs (p = 0.004). Furthermore, evaluating two signalling pathways in Th activation and cell survival showed that the CREB pathway was significantly up-regulated in ICB patients compared to HCs (p = 0.006), but the AKT did not differ. In innate immune responses, the IL-28/or IFN-λ2 expression in ICB patients was significantly higher than in the HCs (p = 0.02). Surprisingly, only one ICB patient disclosed HBx expression, which shows deficient virus activity in these patients. The ICB condition seems to result from host immune pressure on HBV activities, up-regulation of T-bet and IFN-λ. The high expression of CREB may prevent Kupffer's pro-inflammatory reactions in the liver. Whereas the absence of HBx expression in ICB patients and, consequently, the inactivity of HBV may also confirm such immune pressure.

Abstract
Covalently closed circular (ccc) DNA is the template for hepatitis B virus (HBV) replication. The lack of small animal models for characterizing chronic HBV infection has hampered research progress in HBV pathogenesis and drug development. Here, we generated a spatiotemporally controlled recombinant cccDNA (rcccDNA) mouse model by combining Cre/loxP-mediated DNA recombination with the liver-specific "Tet-on/Cre" system. The mouse model harbors three transgenes: a single copy of the HBV genome (integrated at the Rosa26 locus, RHBV), H11-albumin-rtTA (spatiotemporal conditional module), and (tetO)7-Cre (tetracycline response element), and is named as RHTC mouse. By supplying the RHTC mice with doxycycline (DOX)-containing drinking water for two days, the animals generate rcccDNA in hepatocytes, and the rcccDNA supports active HBV gene expression and can maintain HBV viremia persistence for over 60 weeks. Persistent HBV gene expression induces intrahepatic inflammation, fibrosis, and dysplastic pathology, which closely mirrors the disease progression in clinical patients. Bepirovirsen, an antisense oligonucleotide (ASO) targeting all HBV RNA species, showed dose-dependent antiviral effects in the RHTC mouse model. The spatiotemporally controlled rcccDNA mouse is convenient and reliable, providing versatile small animal model for studying cccDNA-centric HBV biology as well as evaluating antiviral therapeutics.

Abstract
INTRODUCTION Hepatitis B virus (HBV) is global health problem. Family members of HBV infected people are considered as high-risk groups due to frequent household transmission of HBV among contacts of HBsAg carriers. The present study aimed to investigate the intrafamilial transmission of HBV among family members of HBV-infected persons and to identify the risk factors for viral transmission in these setting. METHODS 361 index cases and their 1083 family contacts were tested for markers of Hepatitis B, viz. HBsAg and HBcAb using commercial ELISA. The demographic details and risk factors for acquiring HBV infection among the family members were recorded using a structured questionnaire. RESULTS The median (IQR) age of index cases and family members was 37 (27 - 48) and 26 (14 - 38) years, respectively. Among the screened family members, 9.23% (n = 100) members were positive for HBsAg and 32.75% (n = 355) were positive for HBcAb. At least one member of the family was affected in 229/361 (63.43%) index cases. Significantly lower percent of household contacts (9.23%, n = 100)were vaccinated against HBV.HBV transmission risk was significantly higher in families with more than four members(p < 0.0001). Multinomial logistics regression analysis for familial risk factors for transmission of HBV such asclose contact with carrier (aOR overt: 1.172, aOR occult: 1.173), sharing of bed/bedding (aOR overt: 1.258, aOR occult:1.264), personal hygiene items (aOR overt:1.260, aOR occult: 1.451), and eating in common utensils (aOR overt: 2.182, aOR occult: 1.307)were significantly associated with the transmission of HBV (p < 0.05). DISCUSSION Close contact with carrier, sharing of bed/bedding or personal hygiene items and eating in common utensils were significantly associated with the transmission of HBV. Increasing awareness about Hepatitis B infection and vaccination of family members in close contact with carrier is essential to prevent Hepatitis B transmission.

Abstract
With 296 million chronically infected individuals worldwide, hepatitis B virus (HBV) causes a major health burden. The major challenge to cure HBV infection lies in the fact that the source of persistence infection, viral episomal covalently closed circular DNA (cccDNA), could not be targeted. In addition, HBV DNA integration, although normally results in replication-incompetent transcripts, considered as oncogenic. Though several studies evaluated the potential of gene-editing approaches to target HBV, previous in vivo studies have been of limited relevance to authentic HBV infection, as the models do not contain HBV cccDNA or feature a complete HBV replication cycle under competent host immune system. In this study, we evaluated the effect of in vivo codelivery of Cas9 mRNA and guide RNAs (gRNAs) by SM-102-based lipid nanoparticles (LNPs) on HBV cccDNA and integrated DNA in mouse and a higher species. CRISPR nanoparticle treatment decreased the levels of HBcAg, HBsAg and cccDNA in AAV-HBV1.04 transduced mouse liver by 53%, 73% and 64% respectively. In HBV infected tree shrews, the treatment achieved 70% reduction of viral RNA and 35% reduction of cccDNA. In HBV transgenic mouse, 90% inhibition of HBV RNA and 95% inhibition of DNA were observed. CRISPR nanoparticle treatment was well tolerated in both mouse and tree shrew, as no elevation of liver enzymes and minimal off-target was observed. Our study demonstrated that SM-102-based CRISPR is safe and effective in targeting HBV episomal and integration DNA in vivo. The system delivered by SM-102-based LNPs may be used as a potential therapeutic strategy against HBV infection.

Abstract
Commensal microbiota is closely related to Hepatitis B virus (HBV) infection. Gut bacteria maturation accelerates HBV immune clearance in hydrodynamic injection (HDI) HBV mouse model. However, the effect of gut bacteria on HBV replication in recombinant adeno-associated virus (AAV)-HBV mouse model with immune tolerance remains obscure. We aim to investigate its role on HBV replication in AAV-HBV mouse model. C57BL/6 mice were administrated with broad-spectrum antibiotic mixtures (ABX) to deplete gut bacteria and intravenously injected with AAV-HBV to establish persistent HBV replication. Gut microbiota community was analyzed by fecal qPCR assay and 16S ribosomal RNA (rRNA) gene sequencing. HBV replication markers in blood and liver were determined by ELISA, qPCR assay and Western blot at indicated time points. Immune response in AAV-HBV mouse model was activated through HDI of HBV plasmid or poly(I:C) and then detected by quantifying the percentage of IFN-γ+/CD8+ T cells in the spleen via flow cytometry as well as the splenic IFN-γ mRNA level via qPCR assay. We found that antibiotic exposure remarkably decreased gut bacteria abundance and diversity. Antibiotic treatment failed to alter the levels of serological HBV antigens, intrahepatic HBV RNA transcripts and HBc protein in AAV-HBV mouse model, but contributed to HBsAg increase after breaking of immune tolerance. Overall, our data uncovered that antibiotic-induced gut bacteria depletion has no effect on HBV replication in immune tolerant AAV-HBV mouse model, providing new thoughts for elucidating the correlation between gut bacteria dysbiosis by antibiotic abuse and clinical chronic HBV infection.

Abstract
A neonatal vaccination against the Hepatitis B virus (HBV) infection was initiated in Russia 20 years ago, with catch-up immunization for adolescents and adults under the age of 60 years launched in 2006. Here, we have assessed the humoral immunity to HBV in different regions of Russia, as well as the infection frequency following 20 years of a nationwide vaccination campaign. We have also evaluated the role of immune-escape variants in continuing HBV circulation. A total of 36,149 healthy volunteers from nine regions spanning the Russian Federation from west to east were tested for HBV surface antigen (HBsAg), antibodies to HBV capsid protein (anti-HBc), and antibodies to HBsAg (anti-HBs). HBV sequences from 481 chronic Hepatitis B patients collected from 2018-2022 were analyzed for HBsAg immune-escape variants, compared with 205 sequences obtained prior to 2010. Overall, the HBsAg detection rate was 0.8%, with this level significantly exceeded only in one study region, the Republic of Dagestan (2.4%, p < 0.0001). Among the generation vaccinated at birth, the average HBsAg detection rate was below 0.3%, ranging from 0% to 0.7% depending on the region. The anti-HBc detection rate in subjects under 20 years was 7.4%, indicating ongoing HBV circulation. The overall proportion of participants under 20 years with vaccine-induced HBV immunity (anti-HBs positive, anti-HBc negative) was 41.7% but below 10% in the Tuva Republic and below 25% in the Sverdlovsk and Kaliningrad regions. The overall prevalence of immune-escape HBsAg variants was 25.2% in sequences obtained from 2018-2022, similar to the prevalence of 25.8% in sequences collected prior to 2010 (p > 0.05). The population dynamics of immune-escape variants predicted by Bayesian analysis have remained stable over the last 20 years, indicating the absence of vaccine-driven positive selection. In contrast, the wild-type HBV population size experienced a rapid decrease starting in the mid-1990s, following the introduction of mass immunization, but it subsequently began to recover, reaching pre-vaccination levels by 2020. Taken together, these data indicate that it is gaps in vaccination, and not virus evolution, that may be responsible for the continued virus circulation despite 20 years of mass vaccination.

Abstract
Background The incidence of hepatocellular carcinoma (HCC) in patients with hepatitis B virus (HBV) is extremely high. MicroRNAs (miRNAs) are a type of endogenous non-coding small RNA with novel molecular therapeutic mechanisms that plays an important role in the occurrence and development of cancers. This study aimed to explore the regulation mechanism of miR-135a and HOXA10 in the proliferation, invasion, and apoptosis of HCC cells. Methods Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis was used to detect the expression level of miR-135a. Overexpression of miR-135a was used to measure the roles of miR-135a in the proliferation, invasion, and apoptosis of HCC cells. A dual luciferase experiment was performed to assess the relationship between HOXA10 and miR-135a. Western blot was applied to observe the protein levels of p-p38, p-ERK, and p-JNK. Results The expression levels of miR-135a were significantly decreased in HCC tissues and cells. Overexpression of miR-135a inhibited the proliferation and invasion but promoted the apoptosis of HCC cells. Importantly, our results confirmed that HOXA10 was a direct target of miR-135a. Under HBV infection, silencing of HOXA10 significantly blocked the proliferation and invasion and promoted the apoptosis of HCC cells. In addition, miR-135a/HOXA10 regulated the expressions of p-p38, p-ERK, and p-JNK through the miR-135a/HOXA10 axis, thereby inhibiting the activation of the MAPK pathway. Conclusions HBV promoted the proliferation and invasion, and inhibited the apoptosis of HCC cells by regulating the miR-135a/HOXA10 pathway. These findings provide a theoretical basis for improving the treatment of HBV-infected HCC patients.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is a frequent primary liver cancer, and it is one of the leading cause of cancer-related deaths. Hepatitis B virus (HBV) infection is a crucial risk factor for HCC. Thus, this study aimed to explore the prognostic role of HBV-positive HCC related specific genes in HCC. METHODS The HCC related data were downloaded from three databases, including The Cancer Genome Atlas (TCGA), International Cancer Genome Consortium (ICGC), and Gene Expression Omnibus (GEO). Univariate Cox regression analysis and LASSO Cox regression analysis were conducted to build the Risk score. Multivariate Cox regression analysis and survival analysis determined the independent prognostic indicators. RESULTS After cross analysis of differentially expressed genes (DEGs), we have identified 106 overlapped DEGs, which were probably HBV-positive HCC related specific genes. These 106 DEGs were significantly enriched in 213 GO terms and 8 KEGG pathways. Among that, 11 optimal genes were selected to build a Risk score, and Risk score was an independent prognostic factor for HCC. High risk HCC patients had worse OS. Moreover, five kinds of immune cells were differentially infiltrated between high and low risk HCC patients. CONCLUSION The prognostic signature, based on HMMR, MCM6, TPX2, KIF20A, CCL20, RGS2, NUSAP1, FABP5, FZD6, PBK, and STK39, is conducive to distinguish different prognosis of HCC patients.

Abstract
Hepatitis B virus (HBV) can rapidly replicate in the hepatocytes after transmission, leading to chronic hepatitis, liver cirrhosis and eventually hepatocellular carcinoma. Interferon-α (IFN-α) is included in the standard treatment for chronic hepatitis B (CHB). However, this therapy causes serious side effects. Delivering IFN-α selectively to the liver may enhance its efficacy and safety. Imiquimod (IMQ), a Toll-Like Receptor (TLR) 7 agonist, stimulates the release of IFN-α that exhibits potent antiviral activity. However, the poor solubility and tissue selectivity of IMQ limits its clinical use. Here, we demonstrated the use of lipid-based nanoparticles (LNPs) to deliver IMQ and increase the production of IFN-α in the liver. We encapsulated IMQ in two liver-targeted LNP formulations: phospholipid-free small unilamellar vesicles (PFSUVs) and DSPG-liposomes targeting the hepatocytes and the Kupffer cells, respectively. In vitro drug release/retention, in vivo pharmacokinetics, intrahepatic distribution, IFN-α production, and suppression of serum HBV surface antigen (HBsAg) were evaluated and compared for these two formulations. PFSUVs provided >95% encapsulation efficiency for IMQ at a drug-to-lipid ratio (D/L) of 1/20 (w/w) and displayed stable drug retention in the presence of serum. DSPG-IMQ showed 79% encapsulation of IMQ at 1/20 (D/L) and exhibited ∼30% burst release when incubated with serum. Within the liver, PFSUVs showed high selectivity for the hepatocytes while DSPG-liposomes targeted the Kupffer cells. Finally, in an experimental HBV mouse model, PFSUVs significantly reduced serum levels of HBsAg by 12-, 6.3- and 2.2-fold compared to the control, IFN-α, and DSPG-IMQ groups, respectively. The results suggest that the hepatocyte-targeted PFSUVs loaded with IMQ exhibit significant potential for enhancing therapy of CHB.

Abstract
The hepatitis B virus (HBV) transgenic mouse model was used to interrogate the origins of HCC heterogeneity. HBV biosynthesis was used as a marker of liver tumor heterogeneity. Principal component and correlation analysis of HBV and cellular transcript levels demonstrated major differences within and between the gene expression profiles of Apc-deficient, Apc-deficient Pten-deficient, and Pten-deficient HCC. Hence, both oncogenic stimuli and zonal hepatocyte properties determine heterogeneous HCC phenotypes. Additionally, Apc-deficient HCC display decreased expression of Apob, Otc and Tet2 relative to Pten-deficient HCC and control liver tissue suggesting their gene products may represent markers of Apc-deficient HCC. A subset of human HCC with mutations in the β-catenin gene (CTNNB1) displayed a gene expression profile similar to that observed in the mouse Apc-deficient HCC indicating this model of liver cancer may be useful for interrogating the molecular properties of these tumors and their potential therapeutic vulnerabilities.

Abstract
Casein kinase 1α (CK1α) mediates the phosphorylation and degradation of interferon-α/β receptor 1 (IFNAR1) in response to viral infection. However, how CK1α regulates hepatitis B virus (HBV) replication and the anti-HBV effects of IFN-α are less reported. Here we show that CK1α can interact with IFNAR1 in hepatoma carcinoma cells and increased the abundance of IFNAR1 by reducing the ubiquitination levels in the presence of HBV. Furthermore, CK1α promotes the IFN-α triggered JAK-STAT signaling pathway and consequently enhances the antiviral effects of IFN-α against HBV replication. Our results collectively provide evidence that CK1α positively regulates the anti-HBV activity of IFN-α in hepatoma carcinoma cells, which would be a promising therapeutic target to improve the effectiveness of IFN-α therapy to cure CHB.

Abstract
Fatty liver disease and chronic hepatitis B (CHB) are the major causes for chronic liver diseases and the associated adverse outcomes. Concurrent hepatic steatosis has been found to inversely correlate with hepatitis B virus (HBV) activity both in vivo and in vitro; however, the subsequent effects on the prognosis, including advanced fibrosis and hepatocellular carcinoma (HCC) development, remain diverse and inconclusive. Although the newly-proposed criteria of metabolic dysfunction-associated fatty liver disease (MAFLD) help raise disease awareness and facilitate timely diagnosis and management, its clinical impact on patients with CHB, especially after taking the metabolic dysfunction into consideration, is largely unknown and warrants comprehensive investigations to improve the management of CHB population. In this review, these relevant issues are summarized and discussed.

Abstract
Background A high baseline hepatitis B virus (HBV) load has always been listed as an exclusion criterion for programmed cell death-1 (PD-1) inhibitor-associated therapy in clinical trials, as the interaction between HBV load and anti-PD-1/PD-L1 therapy with anti HBV therapy remains controversial. Methods We retrospectively enrolled 70 unresectable HCC patients who were seropositive for HBsAg and accepted tenofovir alafenamide fumarate (TAF) therapy before anti-PD-1 in combination with an antiangiogenic treatment. Patients were divided into a low HBV DNA group (≤ 2000 IU/ml) and a high HBV DNA group (> 2000 IU/ml) according to the baseline HBV DNA levels. Tumour response and progression-free survival (PFS) were compared, and univariate and multivariate Cox analyses were performed to identify potential risk factors for PFS. The incidences of HBV reactivation and HBV-associated hepatitis were also recorded. Results 48 patients were assigned to the low group and the remaining 22 patients were assigned to the high group. The objective response rates (ORRs), disease control rates (DCRs), and PFS between the two groups showed no significant difference (P = 0.761, 0.552, and 0.784, respectively). The results of Cox analyses revealed that there was no relationship between baseline HBV load and PFS. Additionally, HBV reactivation occurred in only 2 patients (2.9%), and no patient experienced HBV-related hepatic impairment when given a continuous TAF treatment. Conclusions Baseline HBV loads do not affect the prognosis of HCC patients receiving anti-PD-1 in combination with an antiangiogenic therapy, while PD-1 inhibitors do not aggravate HBV reactivation and hepatic impairment in patients simultaneously subjected to TAF prophylaxis. Baseline HBV loads do not affect the prognosis of HCC patients receiving anti-PD-1 in combination with antiangiogenic therapy. Besides, PD-1 inhibitors do not aggravate HBV reactivation and hepatic impairment undergoing concurrent TAF prophylaxis.

Abstract
BACKGROUNDS A fully automated, novel, high-sensitivity hepatitis B core-related antigen assay (iTACT-HBcrAg) has been developing. The purpose of this study is to evaluate the efficacy of measuring HBcrAg, using that assay, to diagnose HBV reactivation in a multi-center setting, compared with ultra-high-sensitivity HBsAg (iTACT-HBsAg) and HBV DNA assays. METHODS Forty-four patients with HBV reactivation from 2008 to 2020 were enrolled in four hospitals. Serial serum specimens from the patients were assessed retrospectively for their HBcrAg levels by iTACT-HBcrAg (lower limit of detection; 2.0 log U/mL) and HBsAg levels by iTACT-HBsAg (lower limit of detection; 0.0005 IU/mL); these were compared to the HBV DNA levels. HBV reactivation was defined as detection of serum HBV DNA, including unquantifiable detection. RESULTS At HBV reactivation and/or thereafter, HBV DNA levels were quantified (≥ 1.3 log IU/mL) in the sera of 27 patients, and were below the level of quantification (< 1.3 log IU/mL) in the sera of 17 patients. Of the 27 patients with HBV reactivation and whose serum HBV DNA was quantified, the sera of 26 and 24 patients (96.3% and 88.9%) were positive by iTACT-HBcrAg and iTACT-HBsAg, respectively. HBcrAg was detectable by iTACT-HBcrAg before HBV DNA was quantifiable in 15 of the 27 patients. Of the 11 patients with HBV reactivation and undetectable HBcrAg by iTACT-HBcrAg at HBV reactivation and/or thereafter, 10 had unquantifiable HBV DNA and none developed HBV reactivation-related hepatitis. CONCLUSIONS The iTACT-HBcrAg assay is useful for monitoring HBV reactivation to determine the initiation of treatment with nucleos(t)ide analogues.

Abstract
Background Hepatitis B virus (HBV) is a major human pathogen worldwide. To date, there is no curative treatment for chronic hepatitis B. The mechanism of virion secretion remains to be investigated. Previously, we found that nuclear export of HBc particles can be facilitated via two CRM1-specific nuclear export signals (NES) at the spike tip. Methods In this study, we used site-directed mutagenesis at the CRM1 NES, as well as treatment with CRM1 inhibitors at a low concentration, or CRM1-specific shRNA knockdown, in HBV-producing cell culture, and measured the secretion of various HBV viral and subviral particles via a native agarose gel electrophoresis assay. Separated HBV particles were characterized by Western blot analysis, and their genomic DNA contents were measured by Southern blot analysis. Secreted extracellular particles were compared with intracellular HBc capsids for DNA synthesis and capsid formation. Virion secretion and the in vivo interactions among HBc capsids, CRM1 and microtubules, were examined by proximity ligation assay, immunofluorescence microscopy, and nocodazole treatment. Results We report here that the tip of spike of HBV core (HBc) particles (capsids) contains a complex sensor for secretion of both HBV virions and naked capsids. HBV virion secretion is closely associated with HBc nuclear export in a CRM1-dependent manner. At the conformationally flexible spike tips of HBc particles, NES motifs overlap extensively with motifs important for secretion of HBV virions and naked capsids. Conclusions We provided experimental evidence that virions and naked capsids can egress via two distinct, yet overlapping, pathways. Unlike the secretion of naked capsids, HBV virion secretion is highly CRM1- and microtubule-dependent. CRM1 is well known for its involvement in nuclear transport in literature. To our knowledge, this is the first report that CRM1 is required for virion secretion. CRM1 inhibitors could be a promising therapeutic candidate for chronic HBV patients in clinical medicine.

Abstract
OBJECTIVE Studies report a higher prevalence of HCV, HBV and HIV in the population with Alcohol Use Disorder. Our objective is to determine the seroprevalence for hepatitis B and C and the human immunodeficiency virus (HIV) in patients with alcohol use disorder, as well as to determine if there is a correct serological screening of these. METHODS Retrospective study of 204 patients with Alcohol Use Disorder followed up in the Addictive Behaviors Unit from Albacete. They started treatment from 2013-2014 onwards, the last patient was recruited in December of 2017. RESULTS Our sample has 160 men (78.4%) and 44 women (21.6%). The median age is 46.2 years. 161 patients (78.9%) had HIV serology and it was negative in all. 146 patients (71.6%) had negative hepatitis B serology and 12 (5.9%) were vaccinated. 36 patients (17.6%) had no hepatitis B serology performed. In 10 patients, hepatitis B serology was positive (4.9%; 95% CI 1.9-7.9%). 159 patients (77.9%) had negative hepatitis C serology, and 37 patients had not performed it (18.1%). 8 patients had positive serology (prevalence of 3.9%; 95% CI 1.2-6.6%). Excluding patients who did not have serology, seroprevalence was 5.9% (95% CI 2.3-9.6%) and 4.8% (95% CI 1.5-8.1%) respectively. Failure to perform serologies was associated with older age and less weekly Standard Drink Units (SDUs) consumption. CONCLUSIONS The seroprevalence of HBV and HCV in patients with alcohol use disorder is high. It should be ensured that 100% of patients with alcohol use disorder undergo HCV, HIV, HBV serology, reducing the loss of diagnostic opportunities.

Abstract
Hepatitis B virus (HBV) is a primary cause of chronic liver diseases in humans. HBV infection exhibits strict host and tissue tropism. HBV core promoter (Cp) drives transcription of pregenomic RNA (pgRNA) and plays a key role in the viral life cycle. Hepatocyte nuclear factor 4α (HNF4α) acts as a major transcriptional factor that stimulates Cp. In this work, we reported that BEL7404 cell line displayed a high efficiency of DNA transfection and high levels of HBV antigen expression after transfection of HBV replicons without prominent viral replication. The introduction of exogenous HNF4α and human sodium taurocholate cotransporting polypeptide (hNTCP) expression into BEL7404 made it permissive for HBV replication and susceptible to HBV infection. BEL7404-derived cell lines with induced HBV permissiveness and susceptibility were constructed by stable co-transfection of hNTCP and Tet-inducible HNF4α followed by limiting dilution cloning. HBV replication in such cells was sensitive to inhibition by nucleotide analog tenofovir, while the infection was inhibited by HBV entry inhibitors. This cell culture system provides a new and additional tool for the study of HBV replication and infection as well as the characterization of antiviral agents. BEL7404 cells are characterized by a high transfection efficiency, but do not support canonical HBV replication. BEL7404 cells lack endogenous HNF4α expression, and exogenous HNF4α rescues canonical HBV replication. BEL7404 cells with stable hNTCP and inducible HNF4α expression support HBV infection and inducible replication. BEL7404-derived cell lines supporting HBV infection retain high transfection efficiencies and allow testing of antivirals.

Abstract
Hepatitis B virus (HBV)/Hepatitis C virus (HCV) coinfection is frequently observed because of the common infection routine. Despite the reciprocal inhibition exerted by HBV and HCV genomes, the coinfection of HBV and HCV is associated with more severe forms of liver diseases. However, the complexity of viral interference and underlying pathological mechanism is still unclarified. With the demonstration of absence of direct viral interplay, some in vitro studies suggest the indirect effects of viral-host interaction on viral dominance outcome. Here, we comprehensively investigated the viral replication and host immune responses which might mediate the interference between viruses in HBV/HCV coinfected Huh7-NTCP cells and immunocompetent HCV human receptors transgenic ICR mice. We found that presence of HCV significantly inhibited HBV replication in vitro and in vivo irrespective of the coinfection order, while HBV did not affect HCV replication. Pathological alteration was coincidently reproduced in coinfected mice. In addition to the participation of innate immune response, an involvement of HCV in up-regulating HBV-specific immune responses was described to facilitate HBV clearance. Our systems partially recapitulate HBV/HCV coinfection and unveil the uncharacterized adaptive anti-viral immune responses during coinfection, which renews the knowledge on the nature of indirect viral interaction during HBV/HCV coinfection. HCV inhibited HBV replication in Huh7-NTCP cells. HCV suppressed HBV in immunocompetent mice. Induced innate immune response by HCV limited HBV replication. Presence of HCV enhanced HBV specific immune response. Moderate and acute live injure was caused by HBV/HCV coinfection.

Abstract
Aristolochic acids (AAs) have long been considered as a potent carcinogen due to its nephrotoxicity. Aristolochic acid I (AAI) reacts with DNA to form covalent aristolactam (AL)–DNA adducts, leading to subsequent A to T transversion mutation, commonly referred as AA mutational signature. Previous research inferred that AAs were widely implicated in liver cancer throughout Asia. In this study, we explored whether AAs exposure was the main cause of liver cancer in the context of HBV infection in mainland China. Totally 1256 liver cancer samples were randomly retrieved from 3 medical centers and a refined bioanalytical method was used to detect AAI–DNA adducts. 5.10% of these samples could be identified as AAI positive exposure. Whole genome sequencing suggested 8.41% of 107 liver cancer patients exhibited the dominant AA mutational signature, indicating a relatively low overall AAI exposure rate. In animal models, long-term administration of AAI barely increased liver tumorigenesis in adult mice, opposite from its tumor-inducing role when subjected to infant mice. Furthermore, AAI induced dose-dependent accumulation of AA–DNA adduct in target organs in adult mice, with the most detected in kidney instead of liver. Taken together, our data indicate that AA exposure was not the major threat of liver cancer in adulthood.

Abstract
The distinction between chronic HBeAg-negative hepatitis (CHB) and chronic HBeAg-negative infection (CIB) can be challenging and important for providing advice on prognosis, as well as determining need for treatment. The aim of the present study was to evaluate pgRNA levels in treatment-naïve HBeAg-negative chronic HBV-infected patients. In addition, pgRNA levels were compared to traditional markers in order to assess their clinical utility. A retrospective study was carried out, including 85 cases of CHBs and 74 CIBs. Globally, when the virological markers (pgRNA, qHBsAg, and HBV DNA) were analyzed, significant differences were found between the CHB and CIB groups (P<0.001). Overall, positive correlations were demonstrated, as follows: between pgRNA levels and qHBsAg (Spearman r=0.30, P<0.001), between pgRNA and HBV DNA (Spearman r=0.73, P<0.001), and between pgRNA and ALT (Spearman r=0.67, P<0.001). Out of the 85 CHB patients, 82 (96.5%) agreed to start treatment. At baseline, 38/82 patients, as well as the 3 untreated CHB patients, had undetectable pgRNA levels. The 74 CIB carriers also had undetectable pgRNA levels. During the follow-up period, no patients experienced viral reactivation or progression of liver disease. These results suggest that the addition of plasmatic HBV-pgRNA levels to the traditional diagnostic flowchart of HBeAg-negative patients may improve the correct identification of cases at risk, especially patients with occasional increases in HBV viremia.

Abstract
TRIM5γ, together with TRIM31, has been shown to promote HBx ubiquitination and degradation. This study aimed to explore whether a patient with HCC (hepatic cell carcinoma) having a small nucleotide inserted into the TRIM31 gene, which made a shorter transcript stop at 768 bp, would result in blocking the activity of TRIM31 in promoting HBx degradation. Besides, this study aimed to determine the binding region of the TRIM31-TRIM5γ-HBx complex. HBV (Hepatitis B virus) infection was reported to induce type-III IFN but not type-I or type-II IFNs, here TRIM31 was found to be a type III rather than a type I stimulated gene, which was indispensable in inhibiting the hepatitis B virus replication by the interferon families. Thus, this study further identified the critical role of TRIM31 in the host-hepatitis B virus interaction.

Abstract
Zur Therapie der chronischen Hepatitis-B-Virus-(HBV-)Infektion stehen aktuell pegyliertes Interferon-Alpha und Nucleosid‑/Nucleotidanaloga (Entecavir und Tenofovir) zur Verfügung. Diese Medikamente ermöglichen eine Virussuppression und eine Normalisierung des Leberenzyms Glutamat-Pyruvat-Transaminase (GPT) und verhindern ein Fortschreiten der Lebererkrankung. Zahlreiche noch in klinischer Entwicklung befindliche Therapiestrategien haben jedoch eine funktionelle Heilung zum Ziel. Dabei soll erreicht werden, dass das HBV-Hüllprotein HBsAg im Blutserum nicht mehr nachweisbar ist („ausgeheilte“ Hepatitis B). Der vorliegende Beitrag gibt eine Übersicht über aktuelle und mögliche zukünftige antivirale Therapien gegen die chronische HBV-Infektion. Als Grundlage diente eine Literaturrecherche unter besonderer Berücksichtigung der aktuellen Leitlinien sowie aktueller Kongressbeiträge. Die aktuell verfügbaren antiviralen Therapien führen nur sehr selten zur Elimination von HBsAg (funktionelle Heilung). Auch ist bisher weitgehend unklar, bei welchen Patienten ein Absetzen der Langzeittherapie mit Entecavir bzw. Tenofovir sinnvoll ist. Neue Therapiestrategien in klinischer Entwicklung führen bei einem höheren Anteil der Patienten zur funktionellen Heilung. Wahrscheinlich ist aber eine Kombination mehrerer antiviraler Strategien erforderlich, um die funktionelle Heilung für die Mehrheit der Patienten zu erreichen. Eine solche Therapie kann voraussichtlich in den nächsten 5–10 Jahren vorliegen.

Abstract
Chronic HBV infection is a major cause of hepatocellular carcinoma (HCC) worldwide. The phenotypes of HCC are diverse, in part, due to mutations in distinct oncogenes and/or tumor suppressor genes. These genetic drivers of HCC development have generally been considered as major mediators of tumor heterogeneity. Using the liver-specific Pten-null HBV transgenic mouse model of chronic viral infection, a critical role for liver lobule zone-specific gene expression patterns in determining HCC phenotype and β-catenin-dependent HBV biosynthesis is demonstrated. These observations suggest that the position of the hepatocyte within the liver lobule, and hence its intrinsic gene expression pattern at the time of cellular transformation, make critical contributions to the properties of the resulting liver tumor. These results may explain why therapies targeting pathways modulated by specific identified tumor driver genes display variable treatment efficacy.

Abstract
Hepatitis B virus (HBV) infection is a global public health issue and is a major cause of cirrhosis and hepatocellular carcinoma (HCC). Hepatitis D virus (HDV) requires the hepatitis B surface antigen (HBsAg) to replicate. The eradication of HBV, therefore, can also cure HDV. The current therapies for chronic hepatitis B and D are suboptimal and cannot definitely cure the viruses. In order to achieve functional or complete cure of these infections, novel therapeutic agents that target the various sites of the viral replicative cycle are necessary. Furthermore, novel immunomodulatory agents are also essential to achieve viral clearance. Many of these new promising compounds such as entry inhibitors, covalently closed circular DNA (cccDNA) inhibitors, small interfering RNAs (siRNAs), capsid assembly modulators and nucleic acid polymers are in various stages of clinical developments. In this review article, we provided a comprehensive overview of the structure and lifecycle of HBV, the limitations of the current therapies and a summary of the novel therapeutic agents for both HDV and HBV infection.

Abstract
BACKGROUND Hepatitis B and C virus (HBV and HCV) infections rank among the most frequent infectious diseases with a rising worldwide burden. However, their epidemiology and risk factors are understudied in many regions, including Iran. METHODS This study was conducted as part of the Pars Cohort Study (PCS) in Valashahr district, Fars province (2012-2014). Participants received venipuncture for HBsAg and HCV antibody, followed by Polymerase Chain Reaction (PCR) testing. All infected people and their comparison groups completed a risk assessment questionnaire. RESULTS Overall, 9,269 people participated in the study; the majority were women and of Fars ethnicity. Prevalence of HBsAg and HCV antibody was 2.3% (n = 215) and 0.3% (n = 26), from whom 23% (n = 47) and 13% (n = 3) had indications for treatment, respectively. During follow-up, among HBsAg-positive individuals who were not on treatment, 62% tested negative for HBsAg, and in 2% HBV DNA had risen to treatment levels. Risk factors for HBV infection were illiteracy [OR = 3.43, 95% CI = 1.1, 10.3], and Turk ethnicity compared to Fars [OR = 1.58, 95% CI = 1.1, 2.3]. History of blood transfusion [OR = 2.00, 95% CI = 1.1, 3.5] and history of drug use [OR = 2.85, 95% CI = 1.1, 7.4] were associated with HCV infection, after adjustment. CONCLUSION Further epidemiological studies are needed to identify at-risk populations in different regions. Preventive interventions, including educational programs and transfusion safety strategies, are crucial for reducing the hepatitis burden.

Abstract
OBJECTIVE This study aims to systematically review the performance of red blood cell distribution width to platelet ratio (RPR) in the diagnosis of significant or advanced fibrosis, and cirrhosis associated with Hepatitis B virus (HBV). METHODS The relevant studies were comprehensively searched in English databases such as Web of Science, PubMed, EMBASE, Cochrane Library, as well as Chinese databases such as China National Knowledge Infrastructure, Wanfang Data from the inception to March 2021. Accuracy of RPR in diagnosing significant or advanced fibrosis and liver cirrhosis was assessed by area under the curve (AUC), pooled sensitivity and specificity, as well as positive and negative likelihood ratios. Stata 15.0 software was applied to analyze the data. RESULTS In total, 13 literature met the requirements, including patients with significant fibrosis (n=1890), advanced fibrosis (n=645), and cirrhosis (n=499). The prevalence rates of significant fibrosis, advanced fibrosis and cirrhosis were 49.31% (range: 17.25%-84.21%), 37.07% (range: 9.60%-58.20%) and 2.18% (range: 2.78%-44.19%), respectively. The AUCs for predicting significant fibrosis, advanced fibrosis, and cirrhosis by RPR were 0.73 (95%CI: 0.69-0.76),0.80 (95%CI: 0.77-0.84) and 0.80 (95%CI: 0.76-0.83), respectively. CONCLUSION RPR is of some diagnostic value to the prediction of HBV-related significant fibrosis, advanced fibrosis and cirrhosis.This conclusion is urgently needed to be verified by further multi-center studies of large sample size and rigorous design.

Abstract
BACKGROUND AND AIM The serum hepatitis B core-related antigen (HBcrAg) is considered a surrogate marker of the amount and activity of intrahepatic covalently closed circular DNA. This study aims to investigate the virological characteristics of HBcrAg in chronic hepatitis B (CHB) patients and to reveal the hepatocellular carcinoma (HCC) risk factors of hepatitis B e antigen (HBeAg)-negative patients. METHODS Hepatitis B core-related antigen was measured in 245 naive CHB patients before receiving nucleoside/nucleotide analog (NA) therapy. All patients were receiving NA (entecavir, tenofovir disoproxil fumarate, and tenofovir alafenamide) continuously for more than 1 year until the end of follow-up, and they did not have a history of HCC. Hepatitis B viral status was compared between 106 HBeAg-positive and 139 HBeAg-negative patients. RESULTS Median HBcrAg levels were significantly higher in HBeAg-positive patients than in HBeAg-negative patients (> 6.8 vs 3.7 log U/mL, P < 0.01). In HBeAg-negative patients, higher HBcrAg levels were associated with cirrhosis (119 chronic hepatitis/20 cirrhosis = 3.5/4.7 log U/mL, P = 0.03) and higher serum hepatitis B virus DNA. During a median follow-up of 5.28 (1.03-12.0) years, the 5-year cumulative HCC incidence rate was 5.4% in the HBeAg-negative cohort. In the multivariate Cox regression analysis, higher HBcrAg levels at 1 year were independent predictive factors for HCC development in HBeAg-negative patients who received NA therapy (cutoff value, 4.1 log U/mL; hazard ratio, 6.749; 95% confidence interval, 1.334-34.15, P < 0.01) and even in non-cirrhosis patients. CONCLUSION Hepatitis B core-related antigen was useful for understanding disease progression in CHB patients and for stratifying the risk for carcinogenesis in HBeAg-negative patients receiving NA therapy.

Abstract
Mammalian target of rapamycin (mTOR) is a conserved Ser/Thr kinase that includes mTOR complex (mTORC) 1 and mTORC2. The mTOR pathway is activated in viral hepatitis, including hepatitis B virus (HBV) infection-induced hepatitis. Currently, chronic HBV infection remains one of the most serious public health issues worldwide. The unavailability of effective therapeutic strategies for HBV suggests that clarification of the pathogenesis of HBV infection is urgently required. Increasing evidence has shown that HBV infection can activate the mTOR pathway, indicating that HBV utilizes or hijacks the mTOR pathway to benefit its own replication. Therefore, the mTOR signaling pathway might be a crucial target for controlling HBV infection. Here, we summarize and discuss the latest findings from model biology research regarding the interaction between the mTOR signaling pathway and HBV replication.

Abstract
Hepatitis B virus (HBV) is the causative agent of chronic liver disease and is correlated with the development of subsequent hepatic cirrhosis and hepatocellular carcinoma. Current antiviral therapy using nucleos(t)ide analogs is effective in suppressing viral replication and interrupting disease progression, but HBV is rarely cured completely. Thus, there remains an unmet need for the development of novel anti-HBV drugs. Here, we report the identification of N-(4-Nitrophenyl)-1-phenylethanone hydrazone (ANPH) as a novel structural class of selective inhibitors targeting the replication of the HBV genome using adenovirus vector-mediated HBV genome transduction. ANPH inhibited viral genome replication in HepG2.2.15 cells by inducing the formation of empty capsids devoid of pregenomic RNA without affecting its transcription and translation. Biochemical assays using a truncated core protein consisting of the assembly domain showed that ANPH accelerates the formation of morphologically intact capsids. Taken together, we propose that ANPH might provide a new structural scaffold to design a new anti-HBV drug in medicinal chemistry as well as chemical probes for HBV core protein functions in the future.

Abstract
BACKGROUND Hepatitis B virus deoxyribonucleic acid level (HBV-DNA) ≥5.3 log10IU/mL among pregnant women was recommended as an antiviral therapeutic indicator. However, implementation of HBVDNA testing has varying difficulties in places. In this study, we explored the implementation rate of HBVDNA testing worldwide, and possibility of HBeAg testing replacing HBV-DNA as an antiviral treatment indicator during pregnancy. METHODS We searched five electronic databases including PubMed, Embase, Cochrane Library, Scopus, and China National Knowledge Infrastructure (CNKI) for studies published between Jan 1, 2000, and Nov 16, 2020. Studies were eligible for inclusion if HBV DNA testing implementation rate is available, or if maternal HBV DNA level could be analyzed by HBeAg status. The rates were pooled after data was made a Freeman-Tukey double arcsine transformation. This study is registered with PROSPERO, CRD42021235711. RESULTS A total of 9,575 studies were identified, 79 were finally included in this study. The HBV-DNA testing implementation rate was 36.6% (95% CI, 28.3-45.3%) globally. The rate of HBV-DNA ≥5.3 log10IU/mL was 81.51% (95% CI, 71.68-89.74%) among HBeAg positive pregnant women, and was 4.08% (95% CI, 2.14-6.54%) in HBeAg negative pregnant women. Even if infants were immunized with hepatitis B vaccine and hepatitis B immunoglobulin, the rate of mother-to-child transmission was still 4.87% (95% CI, 4.10-5.68%) among HBeAg positive mothers, and was 0 (95% CI, 0-0.07%) among HBeAg negative mothers, with a RR of 30.40 (95% CI, 11.31-81.72). CONCLUSIONS The implementation rate of HBV DNA testing varies from region to region. Limited studies show that HBV DNA testing does not cover all pregnant women with hepatitis B. When HBV-DNA testing is not available, it is worth considering to use HBeAg positivity as an antiviral therapeutic indicator among HBV-infected pregnant women for preventing MTCT.

Abstract
Statistical analysis in infectious diseases is becoming more important, especially in prevention policy development. To achieve that, the epidemiology, a study of the relationship between the occurrence and who/when/where, is needed. In this paper, we develop the string grammar non-Euclidean relational fuzzy C-means (sgNERF-CM) algorithm to determine a relationship inside the data from the age, career, and month viewpoint for all provinces in Thailand for the dengue fever, influenza, and Hepatitis B virus (HBV) infection. The Dunn's index is used to select the best models because of its ability to identify the compact and well-separated clusters. We compare the results of the sgNERF-CM algorithm with the string grammar relational hard C-means (sgRHCM) algorithm. In addition, their numerical counterparts, i.e., relational hard C-means (RHCM) and non-Euclidean relational fuzzy C-means (NERF-CM) algorithms are also applied in the comparison. We found that the sgNERF-CM algorithm is far better than the numerical counterparts and better than the sgRHCM algorithm in most cases. From the results, we found that the month-based dataset does not help in relationship-finding since the diseases tend to happen all year round. People from different age ranges in different regions in Thailand have different numbers of dengue fever infections. The occupations that have a higher chance to have dengue fever are student and teacher groups from the central, north-east, north, and south regions. Additionally, students in all regions, except the central region, have a high risk of dengue infection. For the influenza dataset, we found that a group of people with the age of more than 1 year to 64 years old has higher number of influenza infections in every province. Most occupations in all regions have a higher risk of infecting the influenza. For the HBV dataset, people in all regions with an age between 10 to 65 years old have a high risk in infecting the disease. In addition, only farmer and general contractor groups in all regions have high chance of infecting HBV as well.

Abstract
INTRODUCTION In quantitative assays for hepatitis B virus (HBV) DNA, although the amplification reaction signal is detected for low-positive cases, quantification remains challenging. HBV reactivation has been reported in many studies, but only a few have focused on HBV low-positive cases. This study aimed to determine the reactivation rate and risk factors for HBV reactivation in low-positive cases. METHODS In this retrospective cohort study, we analyzed 7498 patients who had their HBV DNA measured at Sapporo Medical University Hospital between April 2008 and November 2020. Patient selection criteria were defined as follows: hepatitis B surface antigen was negative; HBV DNA was detectable but not quantifiable at least once. HBV DNA was monitored according to the guidelines for HBV reactivation. RESULTS In total, 49,086 HBV DNA quantitative tests were performed. HBV DNA levels of 2578 tests were detectable but not quantifiable. Eighty patients met the criteria in this study. The median observation period was 497 days, and the 2-year reactivation rate was 15%. Ten patients had low HBV DNA positivity at baseline. Malignant lymphoma was observed in 15 patients; chemotherapy was used to treat other solid tumors in 35 patients, and immunosuppressive therapy was used in 30 patients. Multivariate analysis revealed that HBV DNA detected below the quantification level at baseline was an independent risk factor for HBV reactivation (adjusted hazard ratio 5.82; P = 0.010). CONCLUSIONS Patients with low HBV DNA positivity, especially at baseline, are at high risk for HBV reactivation and therefore require closer monitoring.

Abstract
Background To identify potential key genes predicting unfavorable prognosis in hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC). Methods Gene expression profiles of GSE121248, GSE62232, and GSE55092 from the GEO database were obtained and analyzed. Differentially expressed genes (DEGs) between HBV-associated HCC tissues and adjacent normal tissues were screened by the limma package and Venn diagram software. Functional assessment of DEGs was performed by Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG). Hub genes were selected by the protein-protein interaction (PPI) network and further validated by GSE14520 clinical data. Results A total of 26 up-regulated genes and 76 down-regulated genes were identified by analyzing three databases. GO and KEGG analysis demonstrated that these genes were involved in cell division, metabolism-related biological processes, the p53 pathway, and the cell cycle, among others. PPI network suggested that 14 hub DEGs (TOP2A, HMMR, DTL, CCNB1, NEK2, PBK, RACGAP1, PRC1, CDK1, RRM2, ECT2, BUB1B, ANLN, and ASPM) were most dysregulated and had potential to distinguish between HBV-associated HCC and noncancerous tissues. Further survival analysis of hub genes demonstrated that high expression of TOP2A was significantly associated with poor clinical outcomes of HBV-associated HCC. Conclusions TOP2A might serve as a key gene for prognosis and as a therapeutic target for HBV-associated HCC.

Abstract
Current treatment methods for hepatitis B are mainly antiviral drug therapy and immunotherapy, in which antiviral drugs are mainly nucleoside analogue and interferon. They can significantly reduce the viral load but rarely achieve hepatitis B surface antigen (HBsAg) loss. 3,5,6,7,3',4'-Hexamethoxyflavone was screened out from a small molecule compound library for its lower cytotoxic effect and greater HBsAg inhibition activity. Meanwhile, we further performed experiments in HepG2.2.15, HepG2-NTCP cells, PHHs and HBV transgenic mouse model to evaluate the anti-HBV effects of 3,5,6,7,3',4'-Hexamethoxyflavone. Our study found that 3,5,6,7,3',4'-Hexamethoxyflavone can significantly reduce the level of HBV RNAs, HBV DNA and HBsAg, in addition, the activity of four HBV promoters and the ratio of total RNAs/cccDNA and 3.5 kb RNA/cccDNA were decreased by 3,5,6,7,3',4'-Hexamethoxyflavone. Mechanistically, we found HNF3α plays important roles in Hex mediated HBV transcription inhibition. Our study indicated Hex was a potential anti-HBV therapeutic drug.

Abstract
Hepatitis B remains a major global public health challenge, with particularly high prevalence in medically disadvantaged western Pacific and African regions. Although clinically available technologies for the qPCR detection of HBV are well established, research on point-of-care testing has not progressed substantially. The development of a rapid, accurate point-of-care test is essential for the prevention and control of hepatitis B in medically disadvantaged rural areas. The development of the CRISPR/Cas system in nucleic acid detection has allowed for pathogen point-of-care detection. Here, we developed a rapid and accurate point-of-care assay for HBV based on LAMP-Cas12a. It innovatively solves the problem of point-of-care testing in 10 min, particularly the problem of sample nucleic acid extraction. Based on LAMP-Cas12a, visualization of the assay results is presented by both a fluorescent readout and by lateral flow test strips. The lateral flow test strip technology can achieve results visible to the naked eye, while fluorescence readout can achieve real-time high-sensitivity detection. The fluorescent readout-based Cas12a assay can achieve HBV detection with a limit of detection of 1 copy/μL within 13 min, while the lateral flow test strip technique only takes 20 min. In the evaluation of 73 clinical samples, the sensitivity and specificity of both the fluorescence readout and lateral flow test strip method were 100%, and the results of the assay were fully comparable to qPCR. The LAMP-Cas12a-based HBV assay relies on minimal equipment to provide rapid, accurate test results and low costs, providing significant practical value for point-of-care HBV detection.

Abstract
BACKGROUND Hepatitis B virus (HBV) reactivation consequent to immunosuppressive therapy is an increasingly prevalent problem with serious clinical implications. Treatment with biologic agents conduces to the loss of protective antibody to HBV surface antigen (anti-HBs), which significantly increases the risk of HBV reactivation. Hence, we investigated the risk factors for losing anti-HBs in patients with rheumatic diseases and HBV surface antigen negative/anti-HBs positive (HBsAg-/anti-HBs+) serostatus during treatment with biologic disease-modifying anti-rheumatic drugs (DMARDs). METHODS Using a nested case-control design, we prospectively enrolled patients with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis/psoriasis, or juvenile idiopathic arthritis, who were treated with biologic DMARDs at Changhua Christian Hospital, Taiwan, from January 2013 to June 2019 and had HBsAg-/anti-HBs+ serostatus; the analytic sample excluded all patients with HBsAg+ or anti-HBs- serostatus. Anti-HBs titers were monitored 6-monthly and cases were defined as anti-HBs < 10 mIU/ml during follow-up. Cases were matched one-to-all with controls with anti-HBs ≥ 10 mIU/ml on the same ascertainment date and equivalent durations of biologic DMARDs treatment (control patients could be resampled and could also become cases during follow-up). Between-group characteristics were compared and risk factors for anti-HBs loss were investigated by conditional logistic regression analyses. RESULTS Among 294 eligible patients, 23 cases were matched with 311 controls. The incidence of anti-HBs loss was ~ 2.7%/person-year during biologic DMARDs treatment. Besides lower baseline anti-HBs titer (risk ratio 0.93, 95% CI 0.89-0.97), cases were significantly more likely than controls to have diabetes mellitus (risk ratio 4.76, 95% CI 1.48-15.30) and chronic kidney disease (risk ratio 14.00, 95% CI 2.22-88.23) in univariate analysis. Risk factors remaining significantly associated with anti-HBs loss in multivariate analysis were lower baseline anti-HBs titer (adjusted risk ratio 0.93, 95% CI 0.88-0.97) and chronic kidney disease (adjusted risk ratio 45.68, 95% CI 2.39-871.5). CONCLUSIONS Besides lower baseline anti-HBs titer, chronic kidney disease also strongly predicts future anti-HBs negativity in patients with HBsAg-/anti-HBs+ serostatus who receive biologic DMARDs to treat rheumatic diseases. Patients with low anti-HBs titer (≤ 100 mIU/ml) and/or chronic kidney disease should be monitored during biologic DMARDs therapy, to enable timely prophylaxis to preempt potential HBV reactivation.

Abstract
Background The majority of hepatocellular carcinoma (HCC) is closely associated with hepatitis B virus (HBV) infection, while the mechanism of HCC induced by HBV is debatable. Bone marrow stromal cell antigen 2 (BST-2), an N-glycoprotein, has been characterized as an oncogenic factor in several types of cancer. However, whether BST-2 plays an important role in HCC tumorigenesis remains unknown. Methods A total of 182 HCC tumorous and adjacent nontumor liver tissues were collected. HepG2, Huh7, L02, HepAD38, and HEK293T cell lines were adopted in this study. Tumor proliferation was detected by CCK8, transwell, wound healing, colony formation assays in vitro, and in vivo tumorigenesis was measured by mouse xenografts. NF-κB activation was determined by luciferase assay and Western blot. Protein expression was detected by Western blot, ELISA, or qPCR. Immunoprecipitation was used to confirm the interaction between BST-2 and Syk. Results Here, we observed the higher BST-2 expression in HBV-infected HCC than their paired adjacent tissues and HBV-uninfected HCC tissues, particularly more aberrant non-N-glycosylated BST-2 in HBV-infected HCC tumors. We also observed the increased ER degradation-enhancing α-mannosidase-like protein 3 (EDEM3), which is trimming of N-linked glycans by sequential removal of mannose residues, might result in more non-N-glycosylated form of BST-2. Moreover, we demonstrated that BST-2 and non-N-glycosylated BST-2 N65/92A mutant, not only enhanced the tumor characteristics of hepatoma cell lines in vitro, but also enhanced the growth of mouse xenografts in vivo. Mechanically, N65/92A mutant has stronger ability to promote HCC than BST-2 via NF-κB/ERK1/2 but not NF-κB/anti-apoptotic factors pathway. NF-κB inhibitor attenuated BST-2-mediated tumorigenesis of HCC. Conclusions Our findings illuminate the novel function of BST-2 as an oncogene of HBV-associated HCC, and highlight the novel relationship of N-glycosylation of BST-2 in regulating HCC tumorigenesis in vitro.

Abstract
Hepatitis B virus (HBV) infection remains a global public health problem. Nearly 257 million people worldwide have been infected with HBV, resulting in 887,000 people dying of cirrhosis or liver cancer caused by chronic hepatitis B (CHB) annually. Therefore, identification of new targets against HBV is urgently needed. Long noncoding RNAs (LncRNAs) have gained widespread attention in recent years due to their function in cancer, inflammation and other diseases. Notably, a growing number of lncRNAs have been found to play a role in HBV development. In the present study, we first identified a famous lncRNA, HOTAIR, which was significantly up-regulated in HBV-infected cells and PBMCs from CHB patients. Furthermore, we evaluated the clinical relevance of HOTAIR in 20 CHB patients and found that higher levels of HOTAIR expression were associated with higher ALT/AST levels and were positively correlated with HBsAg and HBV DNA levels. In addition, functional analysis showed that HOTAIR promoted HBV transcription and replication by elevating the activities of HBV promoters via modulation of the levels of cccDNA-bound SP1. In conclusion, our study reveals that HOTAIR expression is correlated with the clinicopathological and physiological characteristics of HBV. Thus, HOTAIR may serve as a novel HBV diagnostic and therapeutic biomarker based on its ability to facilitate HBV transcription and replication.

Abstract
Background: Hemodialysis (HD) patients and kidney transplant (KT) recipients are exposed to be infected by blood-borne viruses (BBVs). Current study was conducted to evaluate the prevalence of BBVs in HD and KT patients in the whole Iranian population. Methods: From Jan 2016 to Dec 2017, 174 hemodialysis and 139 kidney transplant recipients enrolled in this survey. After blood sampling, serum samples were detected for HBV, HCV, HCMV, HIV and HTLV antibodies. Seropositive samples confirmed by Polymerase chain reaction (PCR) method. Results: Overall, 6 (3.44%) and 3 (2.15%) of hemodialysis-dependent and transplantation patients had evidence of HCV infection, whereas no patients were HIV and HBV positive, two cases (1.14%) of hemodialysis and one case (0.71%) of transplantation patients demonstrated the HTLV-1 infection. 52 (37.4%) of patients received graft were positive for HCMV antibody. In addition, our study showed a co-infection of HCMV with HCV (3 patients, 2.15%) in transplantation patients. Conclusion: Prevalence of BBVs infection was lower in comparison to the previous studies. The current strict infection control practices in Iran appear to be effective in limiting dialysis and related infections after transplantation. Because BBVs infections constantly occur especially in dialysis and after transplantation units, our data will be useful to build a new strategic plan for the elimination of BBVs infection in kidney therapycenters.
