Abstract
Interferon-gamma (IFN-γ) has been established to play a pivotal role in the pathogenesis of tuberculosis (TB). Existing evidence suggests a potential association between the genetic poly-morphisms of IFN-γ and the susceptibility to TB. However, this association remains a topic of controversy. To address this knowledge gap, a meta-analysis was conducted to provide more accurate results regarding their relationship. The pooled odds ratio along with its corresponding 95% confidence interval was calculated using four different gene models. This analytical approach served to evaluate the strength of the association between single nucleotide polymorphisms (SNPs) and TB susceptibility. Additionally, we determined whether a fixed effect model or a random effect model should be applied based on the extent of heterogeneity. Egger's test was used to evaluate publication bias. This study included a total of nine studies, involving 4509 patients with TB and 4378 healthy controls. In non-Asian populations, a C > T mutation at polymorphic variant rs2069705 and a T > C mutation at rs2069718 was associated with an increased risk of TB. Conversely, among Asians, the variants rs2069705, rs2069718, and rs1861494 were not significantly associated with the risk of TB. Importantly, our investigation did not reveal any significant publication bias in the pooled results of the four gene models. In conclusion, this meta-analysis suggests that two SNPs in IFN-γ may be associated with TB susceptibility in non-Asian populations. However, for Asians, there is no evidence to support a conclusive relationship between these SNPs and the risk of TB.

Abstract
Interferon-gamma (IFN-γ) is a pro-inflammatory cytokine playing essential role in immunity against tuberculosis (TB). IFN-γ performs function by binding to its receptor complex, consisting of two polypeptide chains viz. IFN-γ receptor 1 (IFN-γR1) and IFN-γ receptor 2 (IFN-γR2). Structural and functional deficiencies in IFN-γR1 can make individual vulnerable to even weak mycobacterial infections. Studies from different populations of the world have reported the association of single nucleotide polymorphisms (SNPs) present in IFNGR1 gene with TB, however, there are no such studies from India. Thus, the present study was designed to analyse the association of rs2234711 (C/T), rs7749390 (C/T) and rs1327475 (C/T) SNPs of IFNGR1 with TB in the population of North India. For the present study, 263 TB patients (at zero day of anti-tuberculosis therapy) and 256 healthy controls (HCs) were recruited. The genotyping of selected SNPs was done by high-resolution melting (HRM) curve analysis. The mRNA and surface expression data of IFNGR1 was extracted from our previous study and was grouped according to the genotypes of studied SNPs. The genotype 'TT' and 'T' allele of SNP rs2234711 (C/T) were found to be associated with TB in studied population ['T' vs 'C': OR (CI) = 1.79 (1.39-2.29); p-value < 0.0001]. The haplotypes 'C-C-C' of rs2234711-rs7749390-rs1327475 confers protection, while haplotype 'T-C-C' is a risk factor for TB in studied population. It was also found that 'TT' genotype of rs2234711 in HCs is associated with lower surface expression of IFNGR1 (p-value = 0.0078). In conclusion, 'TT' genotype is associated with lower surface expression of IFNGR1 and is increasing the susceptibility to TB in North Indian population.

Abstract
The association of IFN-γ receptor 1 (IFNGR1) gene polymorphisms with tuberculosis (TB) susceptibility has not been systematically studied. We therefore conducted a meta-analysis to assess their association. Literature search was conducted in PubMed, EMBASE, Web of Science, and the Cochrane Library. Odds ratio (OR) and 95% confidence interval (CI) was pooled by the random-effect model. Statistical analyses were performed using STATA 12.0 software. Fourteen studies involved 7,699 TB cases and 8,289 controls were included in this meta-analysis. A significant association was found between the IFNGR1 rs2234711 polymorphism and TB susceptibility among Africans in dominant model (OR = 1.24, 95%CI:1.01-1.52), and among Asians in allele model (OR = 0.89, 95%CI: 0.79-0.99), homozygote model (OR = 0.82, 95%CI: 0.70-0.98) and additive model (OR = 0.90, 95%CI: 0.83-0.97). In addition, a significant association was observed between the IFNGR1 rs7749390 polymorphism and TB susceptibility among Africans in allele model (OR = 0.89, 95%CI: 0.82-0.98). No significant association was found between the IFNGR1 rs1327474 polymorphism and TB susceptibility. In summary, IFNGR1 rs2234711 polymorphism was associated with increased TB susceptibility in Africans and decreased TB susceptibility in Asians, while IFNGR1 rs7749390 polymorphism was associated with decreased TB susceptibility in Africans.

Abstract
Genetic and immune factors play an important role in tuberculosis. Under different ethnicities and genetic backgrounds, different immune and inflammation-related gene polymorphisms may confer different susceptibility to tuberculosis. This study investigated the relationship between immune and inflammation-related gene polymorphism and susceptibility to tuberculosis in Xinjiang Uyghur population, China. In this case-control study, we enrolled 507 pulmonary tuberculosis patients and 454 healthy controls from Southern Xinjiang. single nucleotide polymorphism (SNP) genotyping was performed. The 12 SNPs of nine immune and inflammation-related genes (including TNF rs361525, IL6 rs2066992 and rs1524107, IL17A rs3748067, IL17F rs763780, VDR rs731236, rs2228570 and rs1544410, IFNGR1 rs1327474, P2RX7 rs3751143, CTAGE1 rs4331426 and Toll-like receptor 4 (TLR4) rs4986790) and their relationship with tuberculosis were evaluated. The T allele and TT genotype of IL-6 rs2066992 and rs1524107 increased the risk of active tuberculosis. The C allele of IFNGR1 rs1327474 was related to the reduced risk of tuberculosis in the Xinjiang Uyghur population. The G allele and AG/GG genotypes of TLR4 rs4986790 were associated with an increased risk of tuberculosis (p < .05). Furthermore, haplotype analysis found that the haplotype TT of interleukin (IL)-6 was a risk factor, whereas the CG type was a protective factor for active tuberculosis in the Xinjiang Uyghur population. There were three immune and inflammation-related genes (IL-6, IFNGR1 and TLR4) and a total of four SNPs (rs2066992, rs1524107, rs1327474 and rs4986790) related to the susceptibility of the Uyghur population to tuberculosis. Our findings may provide evidence for further understanding the mechanism of tuberculosis susceptibility in the Xinjiang Uyghur population.

Abstract
BACKGROUND Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) refers to a common disorder with unclear etiology and unsatisfactory treatment, which reduces the male's quality of life. OBJECTIVE To examine the effects of genetic polymorphisms of IFNG, IFNGR1, and androgen receptor (AR) on CP/CPPS. METHODS The single nucleotide polymorphisms (SNPs) of IFNG, IFNGR1, and AR were genotyped with the improved multiplex ligation detection reaction. The GTEx, RegulomeDB, HaploReg, and 3DSNP databases were adopted to predict the regulatory functions of the genotyped SNPs. The correlation between SNPs and CP/CPPS was analyzed with the χ 2 test, logistic regression, and two genetic models (codominant and log-additive models). The nomogram was built to predict the risk of CP/CPPS occurrence. RESULTS On the whole, 130 CP/CPPS patients and 125 healthy controls were recruited in the study, and 18 SNPs of IFNG, IFNGR1, and AR were genotyped. The results of functional annotation indicated that the 18 genotyped SNPs might have regulatory effects in the whole blood. The rs144488434 was correlated with the elevated CP/CPPS risk (odds ratio (OR): 2.40, 95% confidence interval (CI): 1.12-5.13, χ 2 = 5.37, and P = 0.021) by the χ 2 test. In the built genetic models, rs10457655 was correlated with the elevated National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) scores (codominant model: GA/GG: crude mean difference (MD) = 0.98, 95% CI: -1.71-3.67 and AA/GG: crude MD = 9.10, 95% CI: 0.58-17.62, P = 0.10). In subgroup analysis, rs2069718 was correlated with the elevated CP/CPPS risk (log-additive model: crude OR = 2.18, 95% CI: 1.03-4.64, and P = 0.034) in patients ≥ 35 years. The nomogram integrating age, rs2069718, rs10457655, and rs144488434 showed good performance to predict the risk of CP/CPPS. CONCLUSIONS Genetic polymorphisms of IFNG, IFNGR1, and AR might act as the genetic factors for CP/CPPS susceptibility, which deserved further explorations.

Abstract
Background Tuberculosis (TB) is an infectious disease, caused by mycobacterium tuberculosis infection, which is associated with oxidative stress and the induction of host antioxidants to counteract this response. The heme oxygenase‐1 (HO‐1) single nucleotide polymorphisms have been reported to be associated with many critical diseases. Our purpose was to investigate the association of HO‐1 single nucleotide polymorphisms with the susceptibility to tuberculosis in Chinese Han population. Methods A case‐control study was performed on Chinese Han population, and a group of 638 TB patients was compared to 610 healthy controls. Three single nucleotide polymorphisms (SNPs) including rs2071746, rs5995098, and rs8140669 were genotyped using the MassARRAY platform. The genotype frequency was compared between TB patients and healthy controls. The association between the three genetic models of the three SNPs and TB risk was further investigated. Results The results showed that, in the case of additive model, there was significant difference of the genotype frequencies of SNP rs8140669 between the TB patients and control groups (P = .038). In the case of dominant model, the genotype frequencies of SNP rs8140669 may have difference between the two cohorts (P = .051), while the allele frequency and genotype distribution for other two SNPs showed no significant difference between the two groups (P > .05). Conclusion HO‐1 polymorphism was associated with TB susceptibility in Chinese Han population.

Abstract
AIM In present survey, we attempted to inquire the plausible linkage of rs1327474 A/G and HCV chronic infection or the clearance of the virus. BACKGROUND IFN-γ signaling pathway is an important trigger for activating antiviral immune responses and production of wide variety of molecules with anti-microbial profiles including type 1 cytokines. Any defect or variation in IFNG signaling pathway may result in susceptibility or progression to diverse diseases such as inflammatory and virus associated disorders. Rs1327474 A/G also known as -611 A/G is an important variation which is located in promoter region of Interferon Gamma Receptor-I (IFNGR1) and may have potent risk for HCV susceptibility. METHODS For this purpose, 154 HCV patients and 200 controls were enrolled in the study, and genomic DNA was isolated from PBMCS and IFNGR1 -611 polymorphism was genotyped by polymerase chain reaction- fragments length polymorphism (PCR-RFLP) method. RESULTS While, AA, AG and GG genotypes frequency included 37.8%, 53.7%, 8.5% in healthy controls, 41.6%, 46.1%, 12.3% were found in chronic HCV patients. Interestingly, allelic percentage was similar in both separated groups within 64.7%, 35.3% and 65.3%, 34.7% were obtained for T and G allele in control and case group respectively. CONCLUSION In spite of our exception for the possible role of this variation in an important promoter region of IFGR1 gene, rs1327474 A/G was not associated with HCV chronic infection among an Iranian studied group. Comprehensively, -611A/G cannot be considered as a risk biomarker for susceptibility to chronic HCV disease.
