Abstract
Background MicroRNAs (miRNAs), a subset of small non-coding RNA molecules, play crucial roles in various pathophysiological processes. Studies increasingly indicate that dysregulated miRNAs are associated with bacterial infection. Nevertheless, little is known about miRNAs that respond to Brucella infection and their potential clinical value. Our research aimed to identify the serum miRNAs altered during Brucella infection. Methods We enrolled serum samples from 73 patients diagnosed with brucellosis and 65 age- and sex-matched control individuals. Illumina sequencing via synthesis (SBS) technology was performed for an initial screen of miRNAs expression profile in serum samples pooled from 29 patients and 29 controls, respectively. A quantitative real-time polymerase chain reaction (qRT-PCR) assay was conducted in the training and validation sets to confirm the concentrations of differentially expressed miRNAs in individual serum samples from 73 patients and 65 controls. Results The Illumina SBS technology identified 1,372 known miRNAs and 1,893 novel miRNAs in brucellosis patients. The three markedly upregulated miRNAs (miR-15a-3p, miR-7-2-3p, miR-103b) in brucellosis patients were subsequently validated by qRT-PCR assay, of which miR-103b was confirmed to be significantly and steadily increased in the brucellosis patients compared with the controls (>2-fold, P<0.001). The area under the receiver operating characteristic (ROC) curve (AUC) for miR-103b was 0.714 (95% CI, 0.624-0.804). Bioinformatics analysis predicted that some putative target genes of miR-103b are involved in immune regulation or the processes of apoptosis and autophagy in humans. Conclusions The serum miR-103b level markedly increases after Brucella infection and has the potential to serve as an auxiliary diagnostic indicator for Brucella infection that deserves further investigation.

Abstract
Brucellosis, caused by the intracellular pathogens Brucella, is one of the major zoonotic infections. Considering the economic burden, its prevalence has been a health concern especially in endemic regions. Brucella is able to survive and replicate within host cells by expressing different virulence factors and using various strategies to avoid the host's immune response. This leads to progression of the disease from an acute phase to chronic brucellosis. Exploration of genetic variations has confirmed the expected influence of gene polymorphisms on susceptibility and resistance to brucellosis of humans. Since there is no approved human vaccine and treatment is uncertain with risk of relapse, it is important to increase knowledge about pathogenesis, diagnosis and treatment of brucellosis in order to manage and control this infection, especially in endemic regions.

Role of CD152 genetic polymorphisms in the susceptibility to breast cancer. Oncotarget 2018; 8:26679-26686. [PMID: 28416762 PMCID: PMC5432289 DOI: 10.18632/oncotarget.15794] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2016] [Accepted: 10/13/2016] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND The polymorphisms in cluster of differentiation 152 (CD152) gene have been reported to be associated with breast cancer (BC), but relevant findings were far from conclusive. Therefore, we carried out this meta-analysis to combine those results for a clearer perspective on this issue. RESULTS In our meta-analysis, a total of 8 eligible publications of 19 case-control studies were selected, which totally contained 7,442 BC cases and 7,376 normal controls. Among the five polymorphisms of CD152 gene, +49 G/A, -1661 A/G and -318 C/T significantly increased the risk of BC under corresponding genetic comparisons; while CT60 G/A polymorphism was negatively related to the cancer susceptibility. In addition, -1772 T/C polymorphism of CD152 gene was not associated with the development of BC. MATERIALS AND METHODS Online databases and other sources were searched for published studies on the relationship between BC susceptibility and CD152 polymorphisms (+49 G/A, -1661 A/G, -1722 T/C, -318 C/T and CT60 G/A). The strength of association was evaluated with pooled odds ratios (ORs) and their corresponding 95% confidence intervals (95% CIs). Heterogeneity evaluation was conducted via Q test. Sensitivity analysis was used to detect the stability of our results. Begg's funnel plot and Egger's test were applied to investigate publication bias among selected studies. CONCLUSIONS The polymorphisms +49 G/A, -1661 A/G and -318 C/T may elevate the susceptibility to BC, but the polymorphism CT60 G/A may offer protection against the cancer.

The Influence of Genetic Variations in the CD86 Gene on the Outcome after Allogeneic Hematopoietic Stem Cell Transplantation. J Immunol Res 2018; 2018:3826989. [PMID: 29577049 PMCID: PMC5821961 DOI: 10.1155/2018/3826989] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2017] [Accepted: 11/14/2017] [Indexed: 01/07/2023] Open
Abstract
CD86 molecule is the ligand for both costimulatory (CD28) and coinhibitory (CTLA-4) molecules, and it regulates immune response after allogeneic hematopoietic stem cell transplantation (alloHSCT). Therefore, we postulate that CD86 gene variations might influence the outcome after alloHSCT. Altogether, 295 adult patients (pts) undergoing related (105 pts) and unrelated (190 pts) donor-matched HSCT were genotyped for the following CD86 gene polymorphisms: rs1129055, rs9831894, and rs2715267. Moreover, the donors' rs1129055 polymorphism was determined. None of the investigated SNPs alone were associated with aGvHD and rate of relapse. However, we showed that rs2715267 SNP influenced overall survival (OS) after alloHSCT. The 24-month OS for the rs271526GG recipients was worse than that for the recipients possessing T allelle (TT or GT genotypes) (p = 0.009). Moreover, analysis of gene-gene interaction between CD86 and CTLA-4 showed that having both the A allele for CD86 rs1129055 and the CTLA-4 CT60GG genotype in recipients increased the risk of aGvHD about 3.5 times. Interestingly, the donors' rs1129055GG genotype and the recipients' CT60GG genotype also increased the risk of aGvHD about 2.7-fold. We postulate that recipients' CD86 gene polymorphisms influence the overall survival after alloHSCT and, together with CTLA-4 polymorphisms, might be considered a risk factor for aGvHD.

Abstract
Leprosy, which is developed by the obligate intracellular Mycobacterium leprae (ML); has different manifestations, associated with the host immune responses. The protective immune response against ML includes T-cell-mediated immunity. The CTLA-4 has a great impact as a negative regulator of the immune response and maintenance of peripheral tolerance. This study analyzed the relationship between CTLA-4+49A/G gene polymorphism and clinical manifestation of leprosy disease and susceptibility among the Azeri population living Northwest Iran. One hundred and ninety-two leprosy patients and 185 healthy controls participated in the study. CTLA-4+49A/G genotyping was conducted via tetra-primer amplification refractory mutation system-polymerase chain reaction (T-ARMS-PCR) analysis. The allelic and genotypic frequencies of +49A/G gene polymorphism were similar in controls and patients. However, older ages, older age of onset and over-representation in male were observed in lepromatous leprosy patient carriers of GG genotype. The current study demonstrates that although CTLA-4+49A/G polymorphism was not correlated with a higher genetic risk for leprosy, the presence of a GG genotype was associated with older ages, older age of onset and over-representation in male in Iranian Azeri population.

Abstract
BACKGROUND The Parsis are one of the smallest religious communities in the world. To understand the population structure and demographic history of this group in detail, we analyzed Indian and Pakistani Parsi populations using high-resolution genetic variation data on autosomal and uniparental loci (Y-chromosomal and mitochondrial DNA). Additionally, we also assayed mitochondrial DNA polymorphisms among ancient Parsi DNA samples excavated from Sanjan, in present day Gujarat, the place of their original settlement in India. RESULTS Among present-day populations, the Parsis are genetically closest to Iranian and the Caucasus populations rather than their South Asian neighbors. They also share the highest number of haplotypes with present-day Iranians and we estimate that the admixture of the Parsis with Indian populations occurred ~1,200 years ago. Enriched homozygosity in the Parsi reflects their recent isolation and inbreeding. We also observed 48% South-Asian-specific mitochondrial lineages among the ancient samples, which might have resulted from the assimilation of local females during the initial settlement. Finally, we show that Parsis are genetically closer to Neolithic Iranians than to modern Iranians, who have witnessed a more recent wave of admixture from the Near East. CONCLUSIONS Our results are consistent with the historically-recorded migration of the Parsi populations to South Asia in the 7th century and in agreement with their assimilation into the Indian sub-continent's population and cultural milieu "like sugar in milk". Moreover, in a wider context our results support a major demographic transition in West Asia due to the Islamic conquest.

Abstract
Pemphigus vulgaris (PV) and pemphigus foliaceus (PF) are rare autoimmune blistering diseases with presumed T-cell-dependent pathology. Activation of naïve T cells is dependent on antigen recognition, subsequent signaling through the T-cell receptor complex (signal 1), and various other interactions of T cells with antigen presenting cells that may be collectively designated as signal 2, which is unconditionally required for T-cell activation both in response to infection and to autoantigens. Among the best described interactions contributing to signal 2 are those mediated by B7 family molecules, such as CD80 and CD86 with their ligands; CD28, providing activation signals; and cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4), conferring inhibition. Single nucleotide polymorphisms (SNPs) within genes encoding those molecules may alter the signaling process. It is not known whether functional genetic polymorphisms within genes encoding the aforementioned proteins may increase risk for developing PV and PF and, if so, whether they might serve as biomarkers for susceptibility to these diseases. To address those questions, we examined functional single nucleotide polymorphisms within CD86 (rs1129055) and CTLA4 (rs733618 and rs5742909) genes in 61 pemphigus patients and 486 healthy controls. We found statistically significant differences in allele and genotype frequencies between PV patients and controls for rs1129055, as well as for rs5742909 among PV and PF patients. Namely, the rs1129055 A allele was significantly more common in PV patients compared with controls (35.4% versus 25.7%, respectively; P = .040), whereas the rs5742909 T allele was significantly more common in PF compared with PV patients (19.2% versus 5.2%, respectively; P = .035). The frequency of the rs5742909 T allele did not, however, differ significantly in PF or in PV compared with controls (10.5%; P = .187 and P = .100, respectively). We report a novel association of SNPs within CD86 and CTLA4 genes with pemphigus. The CD86 rs1129055 A allele appears to confer susceptibility to PV but not to PF. © 2016 Elsevier Inc.

Abstract
Objective To investigate the association between the cluster of differentiation 14 (CD14)-159C/T (rs2569190) gene polymorphism and susceptibility to acute brucellosis in an Iranian population. Methods The study included 153 Iranian patients with active brucellosis and 128 healthy individuals as the control group. Genotyping of the CD14 variant was performed using an amplification refractory mutation system-polymerase chain reaction method. Results The prevalence of CD14-159 TT and CT genotypes were associated with increased risk of brucellosis [odds ratio (OR) = 1.993, 95% confidence interval (95% CI) = 1.07–3.71, P = 0.03 for CT; OR = 3.869, 95% CI = 1.91–7.84, P = 0.01 for TT genotype. Additionally, the minor allele (T) was significantly more frequently present in brucellosis patients than in controls (61% vs. 45%, respectively), and was a risk factor for brucellosis (OR = 3.058, 95% CI = 1.507–6.315, P = 0.01). Conclusions The findings provided suggestive evidence of association of the CD14-159C/T gene polymorphism with susceptibility to acute brucellosis in the Iranian population.

Abstract
BACKGROUND Brucella abortus is an intracellular bacterium that affects humans and domestic animals. Tumor necrosis factor-alpha (TNF-α) has been shown as a key player in the induction of cell-mediated resistance against Brucella infection. We aimed to evaluate the possible influence of the TNF-α promoter polymorphisms (-308 G/A, -238 G/A, and -863 C/A) on the susceptibility of human brucellosis. METHODOLOGY A total of 153 patients with active brucellosis and 128 healthy individuals were recruited. All subjects were genotyped for the polymorphisms in the TNF-α gene by Allele-Specific polymerase chain reaction analysis. RESULTS Our results showed that the TNF-α -308 GG genotype was significantly more frequently present in controls than in brucellosis patients (91% vs. 75%), thus was a protective factor against developing brucellosis (OR=0.313, p=0.001). In contrast, the -308 GA genotype (OR=3.026, p=0.002) and minor allele (A) (OR=3.058, p=0.001) as well as AAG haplotype (OR=4.014, p=0.001) conferred an increased risk of brucellosis. However, the -238 G/A and -863 C/A polymorphisms were not associated with the risk of brucellosis at both allelic and genotypic levels (p>0.05). CONCLUSION Our study revealed that the TNF-α -308 A allele or GA heterozygosity or AAG haplotype were associated with an increased risk of brucellosis in our population.
