Abstract
Non-coding RNAs (ncRNAs), such as microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), have emerged as important regulators of the immune system and are involved in the control of immune cell biology, disease pathogenesis, as well as vaccine responses. A repository of ncRNA-immune associations will facilitate our understanding of ncRNA-dependent mechanisms in the immune system and advance the development of therapeutics and prevention for immune disorders. Here, we describe a comprehensive database, RNA2Immune, which aims to provide a high-quality resource of experimentally supported database linking ncRNA regulatory mechanisms to immune cell function, immune disease, cancer immunology, and vaccines. The current version of RNA2Immune documents 50,433 immune-ncRNA associations in 42 host species, including (1) 6690 ncRNA associations with immune functions involving 31 immune cell types; (2) 38,672 ncRNA associations with 348 immune diseases; (3) 4833 ncRNA associations with cancer immunology; and (4) 238 ncRNA associations with vaccine responses involving 26 vaccine types targeting 22 diseases. RNA2Immune provides a user-friendly interface for browsing, searching, and downloading ncRNA-immune system associations. Collectively, RNA2Immune provides important information about how ncRNAs influence immune cell function, how dysregulation of these ncRNAs leads to pathological consequences (immune diseases and cancers), and how ncRNAs affect immune responses to vaccines. RNA2Immune is available at http://bio-bigdata.hrbmu.edu.cn/rna2immune/home.jsp.

Int Immunopharmacol 2022; 112:109240. [PMID: 36115278 DOI: 10.1016/j.intimp.2022.109240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 08/30/2022] [Accepted: 09/06/2022] [Indexed: 11/18/2022]
Abstract
Adjuvants are required to increase the immunogenicity and efficacy of vaccination and enable vaccine dose sparing. Polyinosinic-polycytidylic acid (Poly I:C), a toll-like receptor 3 agonist, is a promising adjuvant candidate that can induce cell-mediated immune responses; however, it remains unlicensed owing to its low stability and toxicity. Calcium phosphate (CaP), a biocompatible and biodegradable nanoparticle, is widely used in biomedicine for stable and targeted drug delivery. In this study, we developed Poly I:C-functionalized CaP (Poly-CaP) and evaluated its vaccine adjuvant efficacy in vitro and in vivo. A half dose of Poly-CaP nanoparticles showed similar efficacy to a full dose of soluble Poly I:C in stimulating bone marrow-derived dendritic cells and macrophages to secrete proinflammatory cytokines and express their activation markers. Immunization with a half dose of inactivated influenza vaccine in the presence of Poly I:C or Poly-CaP adjuvants induced sufficient antigen-specific humoral responses after boost immunization. Immunization with Poly I:C, CaP, or Poly-CaP-adjuvanted with a half dose of influenza vaccine showed comparable protective efficacy against lethal virus infection, with lower weight loss and virus titer than a full dose of influenza vaccine. The Poly-CaP adjuvant was effective in stimulating antigen-specific CD4+ T cell proliferation in the lungs. Collectively, our results showed that the Poly-CaP adjuvant enhanced antigen-specific cell-mediated immunity and humoral immune responses with vaccine dose-sparing effects, suggesting its potential as a novel vaccine adjuvant candidate.

Abstract
Outbreaks of influenza, caused by the influenza A virus (IAV), occur almost every year in various regions worldwide, seriously endangering human health. Studies have shown that host non-coding RNA is an important regulator of host-virus interactions in the process of IAV infection. In this paper, we comprehensively analyzed the research progress on host non-coding RNAs with regard to the regulation of IAV replication. According to the regulation mode of host non-coding RNAs, the signal pathways involved, and the specific target genes, we found that a large number of host non-coding RNAs directly targeted the PB1 and PB2 proteins of IAV. Nonstructural protein 1 and other key genes regulate the replication of IAV and indirectly participate in the regulation of the retinoic acid-induced gene I-like receptor signaling pathway, toll-like receptor signaling pathway, Janus kinase signal transducer and activator of transcription signaling pathway, and other major intracellular viral response signaling pathways to regulate the replication of IAV. Based on the above findings, we mapped the regulatory network of host non-coding RNAs in the innate immune response to the influenza virus. These findings will provide a more comprehensive understanding of the function and mechanism of host non-coding RNAs in the cellular anti-virus response as well as clues to the mechanism of cell-virus interactions and the discovery of antiviral drug targets.

A recombinant protein containing influenza viral conserved epitopes and superantigen induces broad-spectrum protection. eLife 2021; 10:e71725.

Abstract
Influenza pandemics pose public health threats annually for lacking vaccine that provides cross-protection against novel and emerging influenza viruses. Combining conserved antigens that induce cross-protective antibody responses with epitopes that activate cross-protective T cell responses might be an attractive strategy for developing a universal vaccine. In this study, we constructed a recombinant protein named NMHC that consists of influenza viral conserved epitopes and a superantigen fragment. NMHC promoted the maturation of bone marrow-derived dendritic cells and induced CD4+ T cells to differentiate into Th1, Th2, and Th17 subtypes. Mice vaccinated with NMHC produced high levels of immunoglobulins that cross-bound to HA fragments from six influenza virus subtypes with high antibody titers. Anti-NMHC serum showed potent hemagglutinin inhibition effects to highly divergent group 1 (H1 subtype) and group 2 (H3 subtype) influenza virus strains. Furthermore, purified anti-NMHC antibodies bound to multiple HAs with high affinities. NMHC vaccination effectively protected mice from infection and lung damage when exposed to two subtypes of H1N1 influenza virus. Moreover, NMHC vaccination elicited CD4+ and CD8+ T cell responses that cleared the virus from infected tissues and prevented virus spread. In conclusion, this study provides proof of concept that NMHC vaccination triggers B and T cell immune responses against multiple influenza virus infections. Therefore, NMHC might be a candidate universal broad-spectrum vaccine for the prevention and treatment of multiple influenza viruses.

Abstract
The human brain and central nervous system (CNS) harbor a select sub-group of potentially pathogenic microRNAs (miRNAs), including a well-characterized NF-kB-sensitive Homo sapiens microRNA hsa-miRNA-146a-5p (miRNA-146a). miRNA-146a is significantly over-expressed in progressive and often lethal viral- and prion-mediated and related neurological syndromes associated with progressive inflammatory neurodegeneration. These include ~18 different viral-induced encephalopathies for which data are available, at least ~10 known prion diseases (PrD) of animals and humans, Alzheimer’s disease (AD) and other sporadic and progressive age-related neurological disorders. Despite the apparent lack of nucleic acids in prions, both DNA- and RNA-containing viruses along with prions significantly induce miRNA-146a in the infected host, but whether this represents part of the host’s adaptive immunity, innate-immune response or a mechanism to enable the invading prion or virus a successful infection is not well understood. Current findings suggest an early and highly interactive role for miRNA-146a: (i) as a major small noncoding RNA (sncRNA) regulator of innate-immune responses and inflammatory signaling in cells of the human brain and CNS; (ii) as a critical component of the complement system and immune-related neurological dysfunction; (iii) as an inducible sncRNA of the brain and CNS that lies at a critical intersection of several important neurobiological adaptive immune response processes with highly interactive associations involving complement factor H (CFH), Toll-like receptor pathways, the innate-immunity, cytokine production, apoptosis and neural cell decline; and (iv) as a potential biomarker for viral infection, TSE and AD and other neurological diseases in both animals and humans. In this report, we review the recent data supporting the idea that miRNA-146a may represent a novel and unique sncRNA-based biomarker for inflammatory neurodegeneration in multiple species. This paper further reviews the current state of knowledge regarding the nature and mechanism of miRNA-146a in viral and prion infection of the human brain and CNS with reference to AD wherever possible.

Abstract
Introduction Wild-type adult mice with intact interferon (IFN) system were neither susceptible to bluetongue virus (BTV) infection nor showed signs of morbidity/mortality. Establishment of immunologically competent wild-type adult mouse model with type I IFNs blockade is necessary to assess the pathogenesis, immune responses and testing of BTV vaccines. Objectives Present study aimed to establish and characterize BTV serotype 1 infection in immunocompetent adult mice with type I IFNs blockade at the time of infection by studying immune responses and sequential pathology. Methods Adult mice were administered with anti-mouse IFN-α/β receptor subunit-1 (IFNAR1) blocking antibody (Clone: MAR1-5A3) 24 h before and after BTV serotype 1 infection, and sacrificed at various time points. Sequential pathology, BTV localization by immunohistochemistry and quantification by qRT-PCR, immune cell kinetics and apoptosis by flow cytometry, and cytokines estimation by c-ELISA and qRT-PCR were studied. Results IFNAR blocked-infected mice developed clinical signs and typical lesions of BT; whereas, isotype-infected control mice did not develop any disease. The IFNAR blocked-infected mice showed enlarged, edematous, and congested lymph nodes (LNs) and spleen, and vascular (congestion and hemorrhage) and pneumonic lesions in lungs. Histopathologically, marked lymphoid depletion with “starry-sky pattern” due to lymphocytes apoptosis was noticed in the LNs and spleen. BTV antigen was detected and quantified in lymphoid organs, lungs, and other organs at various time points. Initial leukopenia (increased CD4+/CD8+ T cells ratio) followed by leukocytosis (decreased CD4+/CD8+ T cells ratio) and significantly increased biochemical values were noticed in IFNAR blocked-infected mice. Increased apoptotic cells in PBMCs and tissues coincided with viral load and levels of different cytokines in blood, spleen and draining LNs and notably varied between time points in IFNAR blocked-infected mice. Conclusion Present study is first to characterize BTV serotype 1 infection in immunocompetent adult mouse with type I IFNs blockade. The findings will be useful for studying pathogenesis and testing the efficacy of BTV vaccines.

Abstract
Resveratrol had shown various properties before, like immunomodulatory, anti-inflammatory and antiviral activities. Based on these properties, the present study was designed to evaluate the effects and mechanism of resveratrol as an immune-adjuvant for pseudorabies virus (PRV) vaccine. We found that oral administration of resveratrol to mice significantly increased the number of T lymphocytes in the spleen, and elevated the concentrations of antibodies and cytokines in the serum. Resveratrol (30 mg/kg) could enhance phagocytic capacity of peritoneal macrophage (PM) by boosting the percentage of phagocytosis, phagocytic index and the level of lysozyme. Resveratrol also enhanced antigen presentation function of PM by upregulating the expressions of CD86 and MHC-II. Further study revealed that resveratrol could increase the protein levels of TLR4, Ikk, IκBα, NF-κB and JNK when compared with non-adjuvant group. These results provide further insight into the mechanism of action in adjuvant activity of resveratrol, and also offer preclinical evidence for development as a PRV vaccine adjuvant.

Abstract
Intratumoral (IT) administration of submicron particle docetaxel (NanoDoce®, NanOlogy LLC, Fort Worth, TX, USA) and its efficacy against genitourinary-oncologic xenografts in rats and mice, xenograft-site docetaxel concentrations and immune-cell infiltration were studied. IT-NanoDoce®, IV-docetaxel and IT-vehicle were administered to clear cell renal carcinoma (786-O: rats), transitional cell bladder carcinoma (UM-UC-3: mice) and prostate carcinoma (PC-3: mice). Treatments were given every 7 days with 1, 2, or 3 doses administered. Animals were followed for tumor growth and clinical signs. At necropsy, 786-O and UM-UC-3 tumor-site tissues were evaluated by H&E and IHC and analyzed by LC-MS/MS for docetaxel concentration. Two and 3 cycles of IT-NanoDoce® significantly reduced UM-UC-3 tumor volume (p < 0.01) and eliminated most UM-UC-3 and 786-O tumors. In both models, NanoDoce® treatment was associated with (peri)tumor-infiltrating immune cells. Lymphoid structures were observed in IT-NanoDoce®-treated UM-UC-3 animals adjacent to tumor sites. IT-vehicle and IV-docetaxel exhibited limited immune-cell infiltration. In both studies, high levels of docetaxel were detected in NanoDoce®-treated animals up to 50 days post-treatment. In the PC-3 study, IT-NanoDoce® and IV-docetaxel resulted in similar tumor reduction. NanoDoce® significantly reduced tumor volume compared to IT-vehicle in all xenografts (p < 0.0001). We hypothesize that local, persistent, therapeutic levels of docetaxel from IT-NanoDoce® reduces tumor burden while increasing immune-cell infiltration. IT NanoDoce® treatment of prostate, renal and bladder cancer may result in enhanced tumoricidal effects.

Abstract
The combination of standard-dose chemotherapy and immunotherapy has been shown to be beneficial for patients with non-small cell lung cancer (NSCLC) with good performance status (PS). However, treatment options for patients with poor PS are limited. In the present study, the feasibility and immunological effects of low-dose chemotherapy with carboplatin and paclitaxel combined with immunotherapy with pembrolizumab were examined in patients with metastatic NSCLC and a poor PS. Patients with advanced NSCLC and a PS of 2 were randomized to single-agent pembrolizumab at 200 mg every 3 weeks or pembrolizumab combined with weekly carboplatin area under the curve 1 and paclitaxel 25 mg/m2. Blood for circulating immune cell phenotyping, soluble program death ligand 1 (sPD-L1) and immune-modulatory microRNAs (miRNAs) was collected prior to treatment and at weeks 4 and 7. Ten patients were randomized to the combination arm and 10 to the single-agent arm. Therapy was well tolerated. Four patients discontinued carboplatin due to hypersensitivity reactions but continued pembrolizumab and paclitaxel treatments. Increases in activated CD4+ T cells and in immune-regulatory miRNA, and decreases in myeloid derived suppressor cells were observed in the blood of patients in the combination arm and not in the single-agent arm. Changes in circulating regulatory T cells and sPD-L1 were not observed. Seven patients in the combination arm manifested a partial response compared with only two in the single-agent arm. Weekly low-dose chemotherapy carboplatin and paclitaxel was well tolerated and immunologically active when combined with pembrolizumab in patients with advanced NSCLC and a PS of 2. This combination merits further study in this patient population.

Dose Response 2018; 16:1559325818799561. [PMID: 30263020 PMCID: PMC6153535 DOI: 10.1177/1559325818799561] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2018] [Revised: 07/30/2018] [Accepted: 08/07/2018] [Indexed: 12/11/2022] Open
Abstract
MicroRNAs (miRs), which regulate target gene expression at the
post-transcriptional level, play a crucial role in inducing biological effects
upon high-dose ionizing radiation. Yet, the miR expression profiles in response
to repeated low-dose radiation (LDR) in vivo have not been elucidated. This
study investigated the response profiles of 11 miRs with functions involved in
metabolism, DNA damage and repair, inflammation, and fibrosis in mouse liver,
heart, and testis upon repeated LDR exposure for 4 months. The expression
profiles were evaluated using stem-loop quantitative reverse transcription
polymerase chain reaction immediately and at 2 months after LDR exposure. The
expression profiles varied significantly at both time points. At the organ
level, the heart was the most affected, followed by the liver and testis, in
which significant miR upregulation related to DNA damage response was found.
Metabolism-related miRs decreased in the liver and increased in the testis. The
current results showed immediate and long-lasting alterations in the miR
expression profiles in response to repeated LDR in different organs.

Abstract
INTRODUCTION Cytotoxic chemotherapy might prime urothelial cancer (UC) to checkpoint inhibition, prompting a trial of chemotherapy with the programmed death receptor-1 inhibitor pembrolizumab. PATIENTS AND METHODS Patients with advanced, platinum-refractory UC received pembrolizumab and either docetaxel (arm A) or gemcitabine (arm B). Primary end points were assessments of maximum tolerated dose and dose-limiting toxicity (DLT). Secondary end points were overall response rate (ORR) and progression-free survival (PFS). RESULTS Twelve patients were enrolled in the initial cohorts; 6 in each arm. One DLT was seen in each arm: Grade 3 hypophosphatemia (arm A), Grade 3 diarrhea (arm B). Adverse events of Grade >3 were observed in 7 (54%), the most common being anemia (6; 50%), fatigue (6; 50%), hyponatremia (4; 33%) and neutropenia (3; 25%), with no treatment-related deaths. There were 5 confirmed responses (1 complete, 4 partial), with an ORR of 42% and disease control rate (DCR) of 58%. Arm A had an ORR of 50% and DCR of 67%, whereas arm B had an ORR of 33% and DCR of 50%. Median PFS was 4.8, 5.7, and 3.7 months for the overall cohort, arm A, and arm B, respectively. CONCLUSION Pembrolizumab with either docetaxel or gemcitabine is feasible for treatment of platinum-refractory advanced UC patients. Preliminary efficacy was observed. Further examination is warranted.

Abstract
We aimed to understand the molecular changes in host cells that accompany infection by the seasonal influenza A H1N1 virus because the initial response rapidly changes owing to the fact that the virus has a robust initial propagation phase. Human epithelial alveolar A549 cells were infected and total RNA was extracted at 30 min, 1 h, 2 h, 4 h, 8 h, 24 h, and 48 h post infection (h.p.i.). The differentially expressed host genes were clustered into two distinct sets of genes as the infection progressed over time. The patterns of expression were significantly different at the early stages of infection. One of the responses showed roles similar to those associated with the enrichment gene sets to known 'gp120 pathway in HIV.' This gene set contains genes known to play roles in preventing the progress of apoptosis, which infected cells undergo as a response to viral infection. The other gene set showed enrichment of 'Drug Metabolism Enzymes (DMEs).' The identification of two distinct gene sets indicates that the virus regulates the cell's mechanisms to create a favorable environment for its stable replication and protection of gene metabolites within 8 h.

Abstract
We have previously shown that human nasal epithelial cells (hNECs) are highly permissive cells for respiratory viruses including influenza A virus (IAV) and respiratory syncytial virus. Recent studies have indicated that microRNAs (miRNAs) are involved in virus-host relationship, and this led us to investigate its essential roles in the in vitro hNECs model derived from multiple donors. By comparing the differential expression of miRNAs upon IAV infection among animal and cell line studies, candidates were selected with focus on the initial immune response. After infection of influenza H3N2 virus, hNECs showed constant increase virus titer at 24-72h post-infection (hpi); accompanied with a significantly elevated level of miR-146a-5p at 72 hpi. The exponential elevation of progeny virus titer correlated with a key influenza sensing Toll-like receptor (TLR)7 pathway. TLR7 downstream gene transcripts, myeloid differentiation primary response gene 88 (MyD88), interferon regulator factor 7 (IRF7), and interferon-β (IFN-β) were significantly upregulated at 48 and 72 hpi, while interleukin-1 receptor-associated kinase 1 (IRAK1) and TNF receptor associated factor-6 (TRAF6) were unchanged. Interestingly, when miR-146a was overexpressed with miRNA mimics prior to H3N2 infection, further decreased transcripts of TRAF6, but not IRAK1, were detected. By using the in vitro hNEC model, we demonstrated that H3N2-induced miR-146a specifically targets and regulates TRAF6 expression; but not IRAK expression in the nasal epithelium. We also found that unlike the cell model studies that lead to our studies, when ran across a heterogeneous model of different individual, miRNA signals were highly varied and the expression of most miRNAs, including miR-146a-5p, was more subdued compared to homogenous cell line model, highlighting a need for a more thorough analysis of miRNA signals and targets in a model more mimicking a clinical influenza infection.

Abstract
Vaccination using attenuated vaccines remains an important method to control animal infectious diseases. The present study evaluated ginseng stem-leaf saponins (GSLS) and thimerosal (TS) for their adjuvant effect on an attenuated pseudorabies virus (aPrV) vaccine in mice. Compared to the group immunized with aPrV alone, the co-inoculation of GSLS and/or TS induced a higher antibody response. Particularly, when administered together with GSLS-TS, the aPrV vaccine provoked a higher serum gB-specific antibody, IgG1 and IgG2a levels, lymphocyte proliferative responses, as well as production of cytokines (IFN-γ, IL-12, IL-5 and IL-10) from lymphocytes, and more importantly provided an enhanced cytotoxicity of NK cells and protection against virulent field pseudorabies virus challenge. Additionally, the increased expression of miR-132, miR-146a, miR-147 and miR-155 was found in murine macrophages cultured with GSLS and/or TS. These data suggest that GSLS-TS as adjuvant improve the efficacy of aPrV vaccine in mouse model and have potential for the development of attenuated viral vaccines.

Abstract
Autophagy can mediate antiviral immunity. However, it remains unknown whether autophagy regulates the immune response of dendritic cells (DCs) to influenza A (H1N1) pdm09 infection. In this study, we found that infection with the H1N1 virus induced DC autophagy in an endocytosis-dependent manner. Compared with autophagy-deficient Beclin-1(+/-) mice, we found that bone-marrow-derived DCs from wild-type mice (WT BMDCs) presented a more mature phenotype on H1N1 infection. Wild-type BMDCs secreted higher levels of interleukin-6 (IL-6), tumour necrosis factor- α (TNF-α), interferon-β (IFN-β), IL-12p70 and IFN-γ than did Beclin-1(+/-) BMDCs. In contrast to Beclin-1(+/-) BMDCs, H1N1-infected WT BMDCs exhibited increased activation of extracellular signal-regulated kinase, Jun N-terminal kinase, p38, and nuclear factor-κB as well as IFN regulatory factor 7 nuclear translocation. Blockade of autophagosomal and lysosomal fusion by bafilomycin A1 decreased the co-localization of H1N1 viruses, autophagosomes and lysosomes as well as the secretion of IL-6, TNF-α and IFN-β in H1N1-infected BMDCs. In contrast to Beclin-1(+/-) BMDCs, H1N1-infected WT BMDCs were more efficient in inducing allogeneic CD4(+) T-cell proliferation and driving T helper type 1, 2 and 17 cell differentiation while inhibiting CD4(+) Foxp3(+) regulatory T-cell differentiation. Moreover, WT BMDCs were more efficient at cross-presenting the ovalbumin antigen to CD8(+) T cells. We consistently found that Beclin-1(+/-) BMDCs were inferior in their inhibition of H1N1 virus replication and their induction of H1N1-specific CD4(+) and CD8(+) T-cell responses, which produced lower levels of IL-6, TNF-α and IFN-β in vivo. Our data indicate that autophagy is important in the regulation of the DC immune response to H1N1 infection, thereby extending our understanding of host immune responses to the virus.

Abstract
Conventional chemotherapeutics and targeted antineoplastic agents have been developed based on the simplistic notion that cancer constitutes a cell-autonomous genetic or epigenetic disease. However, it is becoming clear that many of the available anticancer drugs that have collectively saved millions of life-years mediate therapeutic effects by eliciting de novo or reactivating pre-existing tumor-specific immune responses. Here, we discuss the capacity of both conventional and targeted anticancer therapies to enhance the immunogenic properties of malignant cells and to stimulate immune effector cells, either directly or by subverting the immunosuppressive circuitries that preclude antitumor immune responses in cancer patients. Accumulating evidence indicates that the therapeutic efficacy of several antineoplastic agents relies on their capacity to influence the tumor-host interaction, tipping the balance toward the activation of an immune response specific for malignant cells. We surmise that the development of successful anticancer therapies will be improved and accelerated by the immunological characterization of candidate agents.

Abstract
While post-transcriptional regulation of gene expression by microRNAs (miRNAs) has been shown to be involved in influenza virus replication cycle, only a few studies have further investigated this aspect in a human cellular model infected with human influenza viruses. In this study, we performed miRNA global profiling in human lung epithelial cells (A549) infected by two different subtypes of human influenza A viruses (H1N1 and H3N2). We identified a common miRNA signature in response to infection by the two different strains, highlighting a pool of five miRNAs commonly deregulated, which are known to be involved in the innate immune response or apoptosis. Among the five miRNA hits, the only upregulated miRNA in response to influenza infection corresponded to miR-146a. Based on a previously published gene expression dataset, we extracted inversely correlated miR-146a target genes and determined their first-level interactants. This functional analysis revealed eight distinct biological processes strongly associated with these interactants: Toll-like receptor pathway, innate immune response, cytokine production and apoptosis. To better understand the biological significance of miR-146a upregulation, using a reporter assay and a specific anti-miR-146a inhibitor, we confirmed that infection increased the endogenous miR-146a promoter activity and that inhibition of miR-146a significantly increased viral propagation. Altogether, our results suggest a functional role of miR-146a in the outcome of influenza infection, at the crossroads of several biological processes.
