Impact of FOXP3 gene polymorphisms and gene-environment interactions in asthma and atopy in a Brazilian population. Gene 2022; 838:146706. [PMID: 35772656 DOI: 10.1016/j.gene.2022.146706] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Revised: 05/21/2022] [Accepted: 06/24/2022] [Indexed: 11/18/2022]
Abstract
BACKGROUND Polymorphisms in genes related to the activation and development of regulatory T cells (Tregs), such as FOXP3, may be associated with asthma and atopy development. Additionally, environmental factors such as exposure to infections can modify the effect of these associations. This study evaluated the impact of polymorphisms in the FOXP3 on the risk of asthma and atopy as also gene-environment interactions in these outcomes. METHODS This study included 1,246 children from the SCAALA program, between 4 and 11 years of age. DNA was extracted from peripheral blood and eight SNPs (rs2280883, rs11465476, rs11465472, rs2232368, rs3761549, rs3761548, rs2232365 and rs2294021) were genotyped using the 2.5 HumanOmni Beadchip from Illumina (San Diego, California, USA) or TaqMan qRT-PCR. RESULTS The rs2232368 (Allele T) was positively associated with asthma symptoms (OR=1.95, CI=1.04 to 3.66, p = 0.040) and skin prick test (SPT) reactivity to aeroallergens (OR=2.31, CI=1.16 to 4.59, p = 0.017). The rs3761549 (Allele T) was positively associated with SPT reactivity (OR=1.44, CI=1.03 to 2.02, p = 0.034). The rs2280883 (Allele C) was negatively associated with specific IgE to aeroallergens (OR=0.83, CI=0.70 to 0.99, p = 0.040). Furthermore, the rs2280883 played a protective role in the development of atopy only in individuals seropositive to Epstein-Barr virus (EBV) infection (OR=0.74, CI=0.60 to 0.92, p = 0.003 and OR=0.74; 95% CI=0.61-0.91, p = 0.007 for SPT and slgE respectively), but not in individuals without EBV infection. CONCLUSION Polymorphisms in the FOXP3 gene were associated with the risk of atopy and asthma development in our population. In addition, EBV infection had an effect modifier of the observed association for rs2280883 variant.

Abstract
Autoimmune uveitis is characterized by immune disorders of the eyes and the whole body and is often recurrent in young adults, but its pathogenesis is still unclear. IL-35 is an essential regulatory factor in many autoimmune diseases, which is produced by Breg cells and can induce Breg cells to regulate the immune response. The relationship between the expression and gene polymorphism of IL-35 and the immune status of patients with autoimmune uveitis has not been reported. The peripheral blood of the subjects was collected from patients with Behçet’s Disease (BD) and those with Vogt–Koyanagi–Harada (VKH) syndrome. The percentage of immune cell subsets including B cells, DC, and T cells, and the expression of IL-35 in serum of these two kinds of disease were analyzed. And then, the associations between seven IL-35 single nucleotide polymorphism (SNP) sites and disease susceptibility, the immune status, the clinical characteristics, and the serum IL-35 levels were analyzed. Our results showed that the percentage of Breg cells was significantly decreased in the blood of patients with VKH syndrome compared to that of healthy controls. The levels of IL-35 in the serum of patients with VKH syndrome or BD patients were not changed significantly, compared to that of healthy controls. Furthermore, the associations between two subunits of IL-35 (IL-12p35 and EBI3) and BD or VKH patients were analyzed. We found that there was an association between the EBI3 rs428253 and the occurrence of BD. There was an association between the IL-12p35 rs2243131 and the low level of Breg cell of VKH patients. In addition, there were associations between the polymorphisms of EBI3 rs4740 and the occurrence of headache and tinnitus of VKH patients, respectively. And the genotype frequency of IL-12p35 rs2243115 was related to the concentration of serum IL-35 in patients with VKH syndrome. Thus, the specific SNP sites change of IL-35 were correlated to the immune disorders in uveitis. And they may also play a guiding role in the occurrence of clinical symptoms in patients with uveitis, especially for VKH syndrome.

BMC Cardiovasc Disord 2021; 21:6. [PMID: 33407151 PMCID: PMC7789631 DOI: 10.1186/s12872-020-01811-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Accepted: 12/03/2020] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND The relationship between IL-35 genes polymorphism and susceptibility to coronary heart disease has not been tested in the largest Han population in China. The aim of this study was to explore the effect of single nucleotide polymorphisms (SNPs) of interleukin-35 (IL-35) genes and its relationship with environment on the risk of coronary heart disease (CHD). METHODS We performed Hardy-Weinberg equilibrium test on the control group. The relationship between the four SNPs of IL-35 genes and the risk of coronary heart disease was studied by multivariate logistic regression. The best interaction was identified with generalized multifactor dimensionality reduction (GMDR). Logistic regression was used for investigation on association between four SNPs and CHD risk. RESULTS Logistic regression analysis showed that the C allele of rs428253 and the G allele of rs2243115 were independently correlated with increased risk of CHD, and adjusted ORs (95% CI) were 1.91 (1.28-2.64) and 1.80 (1.30-2.23), respectively. However, there was no significant association between CHD and rs4740 or rs568408. GMDR model indicated a best model for CHD risk consisted of rs428253 and current smoking, which scored 10/10 for both the sign test and cross-validation consistency (p = 0.010). Therefore, this overall multi-dimensional model had the highest cross-validation consistency, regardless of how the data were divided. This provided an evidence of gene-environment interaction effects. We also found that current smokers with rs428253-GC/CC genotype have the highest CHD risk, compared to never smokers with rs428253-GG genotype, OR (95% CI) = 3.04 (1.71-4.41), after adjustment for age, gender, hypertension, T2DM and alcohol consumption status. CONCLUSIONS In this study, the C allele of rs428253 and the G allele of rs2243115, and the interaction rs428253 and current smoking were correlated with increased risk of CHD.

Abstract
BACKGROUND The role of FoxP3, a master regulator of T regulatory cells, in allergic diseases such as asthma is of immense importance yet the effect of its gene variants on the disease predisposition is not fully understood. We studied the association of FoxP3 polymorphisms (-2383C/T and -3279C/A) in allergic asthma patients and their correlation with serum IL-4, IL-13, Total IgE, and Vitamin D levels. METHODS In this study 350 individuals were enrolled, 150 allergic asthma patients and 200 healthy controls. SNP analyses were performed by RFLP. IL-4, IL-13 vitamin D and Total IgE were measured by ELISA. RESULTS The AA homozygous mutant of -3279C/A posed a three-fold risk [P < 0.005; OR, 3.52] whereas the -2383C/T variants TT genotype carried a fourfold risk [P = 0.002; OR, 4.04]. Haplotype analysis exhibited predisposition to allergic asthmawith CC/TT [P = 0.01; OR 5.93 (95%CI)], AA/CC [P = 0.01; OR 3.29] and AA/TT haplotypes [P = 0; OR 11.86 (1.31-85.87)]. A negative correlation between IgE and Vitamin D was found [r = -0.30p-value 0.001] but a negative correlation betweenIgE and Vit D was established in the haplotype CC/TT [r = -0.45P = 0.002] and CC/CT [r = -0.52P = 0.04]. In allergic patients, the eosinophils count was high [p = 0.003] and the mean levels of pro-inflammatory cytokines IL-4 and IL-13 were elevated [P < 0.001] as well. CONCLUSIONS The study suggests SNP -3279 -AA genotype and, -2383-TT genotype in association with certain haplotypes pose a risk for allergy development. There was no correlation between different genotypes and serum levels of various cytokines.

Abstract
Obesity, a chronic low-grade inflammation metabolic abnormality, is related to high proinflammatory cytokines concentrations. Epstein-Barr virus-induced gene 3 (EBI3) encodes for the EBI3 beta subunit that constitutes interleukin (IL) 27 and 35. Our objective was to assess the association of three EBI3 single nucleotide polymorphisms (SNPs) with the presence of central obesity in a group of Mexican subjects. The rs428253, rs4740, and rs4905 EBI3 SNPs were genotyped in 1323 individuals (1092 central obese and 231 non-central obese). We also analyzed IL-6, IL-27, and IL-35 concentrations. Under different models, the rs4740 (OR = 0.384, Precessive = 0.010; OR = 0.404, Pcodominant 2 = 0.019) and rs4905 (OR = 0.380, Precessive = 0.009; OR = 0.404, Pcodominant 2 = 0.018) were related with a low risk of central obesity. In central obese subjects, the SNPs were related to lower risk of hypoalphalipoproteinemia (rs4740) and with high IL-6 concentrations (rs428253, rs4740, and rs4905), whereas in non-central obese individuals, the rs428253 was related with low risk of increased visceral abdominal fat and hypertriglyceridemia. Interleukin-6, IL-27 and IL-35 concentrations were similar in both groups and no relation was noticed with the studied genotypes. Our results suggest an association of EBI3 SNPs with a low risk of central obesity and with a few risk factors for cardiovascular disease in individuals with and without central obesity.

[PMID: 32529476 DOI: 10.1007/s00011-020-01368-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2020] [Revised: 05/12/2020] [Accepted: 05/23/2020] [Indexed: 12/31/2022] Open
Abstract
OBJECTIVES Allergic rhinitis (AR) is a chronic inflammatory disease of nasal mucosa. Loss of function of Th17 cells and regulatory T (Treg) cells plays a role in the pathogenesis of AR. IL18, FOXP3, and IL13 are key genes in the development of AR. However, the genetic associations between IL18, FOXP3 and IL13 genes polymorphisms and AR risk were inconclusive yet. METHODS A meta-analysis was performed by searching through Pubmed, EMBASE, web of science and CNKI databases. The ORs and 95%CIs were used to assess the genetic association between the allelic, dominant and recessive models of IL18, FOXP3 and IL13 genes polymorphisms and AR risk. RESULTS A total of 15 articles (6 for FOXP3, 5 for IL18, and 5 for IL13) were enrolled in the present study. No association was detected between the IL18 rs187238, rs1946518, rs360721, FOXP3 rs2232365, rs3761548 and IL13 rs1800925 polymorphisms and AR risk (p > 0.05). Significant associations were observed between the allelic (p = 0.001, OR 1.32, 95% CI 1.12-1.56), dominant (p = 0.005, OR 1.43, 95% CI 1.11-1.83) and recessive models (p = 0.01, OR 1.64, 95% CI 1.13, 2.40) of IL13 rs20541 and AR risk. Subgroup analysis based on ethnicity revealed that the IL13 rs20541 was significantly associated with AR risk in Asian population (allelic model: p = 0.009, OR 1.36, 95% CI 1.13-1.63, dominant model: p = 0.005, OR 1.43, 95% CI 1.11-1.83; recessive model: p = 0.01, OR 1.64, 95% CI 1.13-2.40). CONCLUSIONS IL13 rs20541 may contribute to the risk of AR in Asian population. To confirm these results, larger number of case-control study with more subjects is necessary in the future.

Abstract
Dysfunction of regulatory T cells (Tregs) may contribute to certain immune-related pregnancy complications. Forkhead box protein 3 (FOXP3) is the key transcription factor of Treg. We performed a systematic review and meta-analysis to evaluate the possible association between FOXP3 polymorphisms -924A/G (rs2232365) and -3279C/A (rs3761548) and immune-related pregnancy complications. After reviewing 78 fully published studies, 10 studies fulfilled previously defined eligibility criteria and were used for meta-analysis. Two single nucleotide polymorphisms showed a significant correlation with increased or reduced risk for immune-related pregnancy complications. For rs3761548, women with allele A were significantly at a higher risk than women carrying allele C (odds ratio = 1.29, 95% confidence interval: 1.20-1.38; p = 0.001). For rs2232365, women with GG or AG genotype were at a higher risk than women with genotype AA, thereby, allele G was significantly associated with a higher risk than allele A. Our meta-analysis supports the notion that immune-related pregnancy complications might be linked to genetic variations in the FOXP3 gene.

Abstract
OBJECTIVES Inflammatory cytokines play an important role in the pathogenesis of cardiovascular disease. Few studies have investigated the association between interleukin-35 (IL-35) genetic variants and the risk of coronary heart disease (CHD). We examined the association between IL-35 polymorphisms and CHD in the Chinese Zhuang population. PATIENTS AND METHODS A total of 707 CHD patients and 707 age-matched and sex-matched controls were enrolled in this case-control study. Genotypes of the single nucleotide polymorphisms (SNPs) of IL-35, including rs428253, rs6613, rs9807813, rs2243115, rs568408, rs582054, rs583911, rs4740, and rs393581, were examined by MassArray. Plasma IL-35 level was measured using an enzyme-linked immunosorbent assay. The multivariate logistic regression model was used to evaluate the association between the SNPs and the risk of CHD. RESULTS In the Chinese Zhuang population, compared with the GG genotype of EBI3 rs428253, individuals with the CC genotype had a 2.02-fold (95% confidence interval: 1.07-3.84, P=0.031) higher risk of CHD. Further adjustment for potential risk factors did not alter the positive association (CC vs. GG, odds ratio=2.30, 95% confidence interval: 1.16-4.54, P=0.042). SNPs rs4740, rs2243115, rs568408, and rs582054 were not statistically related to the risk of CHD. The plasma IL-35 levels showed a marginally significant difference between rs428253 genotypes [GG: 13.39 (7.89-19.25) vs. CC+GC: 17.53 (8.98-22.56) pg/ml, P=0.057]. CONCLUSION The EBI3 rs428253 CC genotype was associated with an increased risk of CHD in the Chinese Zhuang population, although no significant difference in IL-35 levels was observed between genotypes in healthy controls.

Abstract
Interleukin-35 (IL-35) exerts crucial roles in the pathogenesis and development of systemic lupus erythematosus (SLE), in this study we aim to explore the associations between IL-35 gene polymorphisms and the susceptibility, clinical features and plasma IL-35 levels of SLE patients, respectively. 490 SLE patients and 489 healthy controls were recruited in our study. The correlations between the polymorphisms of seven SNPs of IL-35 encoding gene and the susceptibility, main clinical manifestations of SLE were evaluated, respectively. Plasma IL-35 levels were assessed in 76 SLE patients, and the associations between plasma IL-35 levels and the polymorphisms of genotyped SNPs were explored. There were significant associations between the polymorphisms of rs4740 and the occurrence of renal disorder, hematological disorder in SLE patients, respectively (p = 0.001; p = 0.001). In addition, there were no significant associations observed between the genotype frequencies of genotyped SNPs and the risk of SLE, plasma IL-35 levels, respectively. The polymorphism of rs4740 of IL-35 encoding gene is associated with the occurrence of renal disorder and hematological disorder of SLE patients.

Genetic polymorphism in association with susceptibility to tuberculosis: a study in a Pakistani population. Braz J Microbiol 2019; 50:429-434. [PMID: 30805894 DOI: 10.1007/s42770-019-00048-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2018] [Accepted: 12/17/2018] [Indexed: 10/27/2022] Open
Abstract
Tuberculosis is becoming a global issue with raising occurrences; particularly in developing countries, the situation is alarming. Besides environmental factors, host genetic factors are vital in disease development. A demographical and genotypic analysis in relation to tuberculosis commencement is conducted in a Pakistani population, and genotypic frequency of EBI3 (rs4740) was analyzed. Allelic frequencies of EBI3 (rs4740) were significantly associated with disease susceptibility in the reviewed population. Analysis for EBI3 (rs4740) genotyping showed a significant association of "GG" with reduced risk for disease. Moreover, females and older age found to be more perilous to develop TB while smoking and a family history of TB are additional risk factors for disease development. Further work with a larger population is necessary to identify the true causative variants of tuberculosis.

Abstract
Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2-3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of Journal Articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.

Abstract
Regulatory T cells (Tregs) represent a cell type that promotes immune tolerance to autologous components and maintains immune system homeostasis. The abnormal function of Tregs is relevant to the pathogenesis of several skin diseases like psoriasis, atopic dermatitis, systemic lupus erythematosus, cutaneous T-cell lymphomas, and skin cancer and is also important in rheumatoid arthritis, diabetes and other autoimmune diseases. In this review, we will summarize the role of mutations and/or polymorphisms of genes involved in Tregs development, and functions in the pathogenesis of selected skin diseases.

Abstract
The transcription factor forkhead box protein 3 (FOXP3) is an essential molecular marker of regulatory T cell (Treg) development in different microenvironments. Tregs are cells specialized in the suppression of inadequate immune responses and the maintenance of homeostatic tolerance. Studies have addressed and elucidated the role played by FOXP3 and Treg in countless autoimmune and infectious diseases as well as in more specific cases, such as cancer. Within this context, the present article reviews aspects of the immunoregulatory profile of FOXP3 and Treg in the management of immune homeostasis, including issues relating to pathology as well as immune tolerance.

Abstract
Interleukin 35 (IL-35) is a heterodimeric cytokine involved in the development of atherosclerosis. The aim of the present study was to establish if the polymorphisms of IL-12A and EBI3 genes that encode the IL-35 subunits are associated with the development of premature coronary artery disease (CAD) in Mexican individuals. The IL-12A and EBI3 polymorphisms were determined in 1162 patients with premature CAD and 873 controls. Under different models, the EBI3 rs428253 (OR = 0.831, Padd = 0.036; OR = 0.614, Prec = 0.033; OR = 0.591, Pcod2 = 0.027) and IL-12A rs2243115 (OR = 0.674, Padd = 0.010; OR = 0.676, Pdom = 0.014; OR = 0.698, Phet = 0.027; OR = 0.694, Pcod1 = 0.024) polymorphisms were associated with decreased risk of developing premature CAD. Some polymorphisms were associated with clinical and metabolic parameters. Significant different levels of IL-35 were observed in EBI3 rs4740 and rs4905 genotypes only in the group of healthy controls. In summary, our study suggests that the EBI3 and IL-12A polymorphisms play an important role in decreasing the risk of developing premature CAD; it also demonstrates the relationship of the EBI3 rs4740 and rs4905 genotypes with IL-35 levels in healthy individuals.

Abstract
Parkinson's disease (PD) is one of the most common neurodegenerative disorders. Accumulated evidence confirms that genetic factors play a considerable role in PD pathogenesis. To examine whether point variants or haplotypes are associated with PD development, genotyping of 35 variants in 22 PD-related genes was performed in a well-characterized cohort of 512 Han Chinese PD patients and 512 normal controls. Both Pearson's χ2 test and haplotype analysis were used to evaluate whether variants or their haplotypes were associated with PD in this cohort. The only statistically significant differences in genotypic and allelic frequencies between the patients and the controls were in the DnaJ heat shock protein family (Hsp40) member C10 gene (DNAJC10) variant rs13414223 (P = 0.004 and 0.002, respectively; odds ratio = 0.652, 95% confidence interval: 0.496-0.857). No other variants or haplotypes exhibited any significant differences between these two groups (all corrected P > 0.05). Our findings indicate that the variant rs13414223 in the DNAJC10 gene, a paralog of PD-related genes DNAJC6 and DNAJC13, may play a protective role in PD. This suggests it may be a PD-associated gene.

Abstract
Parkinson's disease (PD) is a common age-dependent neurodegenerative movement disorder related to multiple factors, and genetic factors play an important role in the pathogenesis of PD. Variants in the methylenetetrahydrofolate reductase gene (MTHFR), a gene encoding a folate-dependent enzyme that is involved in homocysteine metabolism, have been reported to be associated with PD. To explore the role of the MTHFR gene in the development of PD in Chinese Han population, we analyzed two MTHFR variants (rs1801131 and rs1801133) in a patient cohort consisting of 512 patients with PD from mainland China and a control cohort consisting of 512 age, gender and ethnicity matched normal subjects. Statistically significant differences in genotypic and allelic frequencies were detected in the MTHFR variant rs1801133 (P=0.022 and 0.007, respectively; odds ratio=0.780, 95% confidence interval=0.651-0.934). In addition, the A-T haplotype of rs1801131-rs1801133 showed a protective role against PD development (P=0.007, odds ratio=0.779, 95% confidence interval=0.650-0.933). Our results suggested that the T allele of rs1801133 variant and A-T haplotype of rs1801131-rs1801133 in the MTHFR gene may decrease the risk of developing PD in Chinese Han population from mainland China.

Abstract
Multiple factors interact to trigger allergic diseases, including individual genetic background and factors related to the environment such as exposure to allergens, air pollution and respiratory infections. The FOXP3 transcription factor is constitutively expressed in CD4+CD25+FOXP3+ regulatory T cells (Tregs) and is critical for the maintenance of immune homeostasis. For example, FOXP3 is responsible for the suppression of the Th2 response following exposure to allergens. Studies have shown that expression of the FOXP3 gene is reduced in patients with asthma and allergies compared to healthy controls. Therefore, the impairment of FOXP3 function caused by genetic polymorphisms and/or epigenetic mechanisms may be involved in the etiology of asthma and other allergic diseases. This review discusses some aspects of the role of FOXP3 in the development of asthma and allergy, with a particular emphasis on genetic and epigenetic factors.

Abstract
OBJECTIVE The aim of this study was to explore whether the FOXP3 -3279 A/C polymorphism and (GT)n microsatellite polymorphisms are associated with susceptibility to autoimmune diseases. METHODS A meta-analysis was conducted on the associations between the FOXP3 -3279 A/C polymorphism and (GT)15 and (GT)16 polymorphisms and autoimmune diseases. RESULTS Twenty-two comparative studies with a total of 7962 patients and 7453 controls were included in the meta-analysis. Meta-analysis revealed an association between autoimmune disease and the FOXP3 -3279 AA + AC genotype (OR = 1.480, 95% CI = 1.263-1.614, p < 1.0 × 10(-9)), and stratification by ethnicity indicated a significant association between the FOXP3 -3279 AA + AC genotype and autoimmune diseases in Asians (OR = 1.416, 95% CI = 1.225-1.637, p = 2.5 × 10(-7)) and non-Caucasians (OR = 1.432, 95% CI = 1.245-1.647, p = 7.5 × 10(-8)). In addition, corrected p values for multiple testing remained significant. Meta-analysis revealed no association between autoimmune disease and the FOXP3 (GT)15 allele (OR = 1.051, 95% CI = 0.933-1.183, p = 0.413). Similarly, the FOXP3 (GT)16 allele showed no associations with autoimmune disease. CONCLUSIONS This meta-analysis indicates that the FOXP3 -3279 A/C polymorphism is associated with susceptibility to autoimmune disease in Asians and non-Caucasians.

Abstract
Tuberculosis (TB) remains a major global health problem and host genetic factors play a critical role in susceptibility and resistance to TB. The aim of this study was to identify novel candidate genes associated with TB susceptibility. We performed a population-based case-control study to genotype 13 tag SNPs spanning Epstein-Barr virus-induced gene 3 (EBI3), colony stimulating factor 2 (CSF2), IL-4, interferon beta 1 (IFNB1), chemokine (C-X-C motif) ligand 14 (CXCL14) and myeloid differentiation primary response gene 88 (Myd88) genes in 435 pulmonary TB patients and 375 health donors from China. We observed that EBI3 gene rs4740 polymorphism was associated with susceptibility to pulmonary tuberculosis (PTB) and the allele G was associated with a protective effect against PTB. Furthermore, EBI3 deficiency led to reduced bacterial burden and histopathological impairment in the lung of mice infected with Mycobacterium bovis BCG. Meanwhile, higher abundance of EBI3 was observed in the granuloma of PTB patients and in the lung tissue of BCG-infected mice. Of note, the expression of EBI3 in macrophages was remarkably induced by mycobacteria infection at both mRNA and protein level. In conclusion, EBI3 gene rs4740 polymorphism is closely associated with susceptibility to PTB and the elevation and enrichment of EBI3 in the lung which at least partially derived from macrophages may contribute to the exacerbation of mycobacterial infection.

Abstract
Background Forkhead box protein 3 (FOXP3), a transcription factor required for development and function of regulatory T cell, and Epstein-Barr virus–induced gene 3 (EBI3), a downstream target of FOXP3, may be important in the development of chronic rhinosinusitis (CRS) with or without sinonasal polyposis (CRSwNP and CRSsNP, respectively). Our objective was therefore to examine the presence of any associations between specific single nucleotide polymorphisms (SNPs) in/around the FOXP3 and EBI3 genes and risk for CRS in Chinese subjects. A population-based case–control association analysis was performed. Methods DNA extracted from peripheral blood leukocytes from 667 subjects with CRS (360 CRSwNP and 306 CRSsNP) and 330 healthy controls was assessed for SNPs selected and complemented with tagging SNPs. A total of seven SNPs (4 in FOXP3 and 3 in EBI3 genes) were genotyped and genetic association tests were performed. Results In the single-locus analyses of CRS risk, the allele frequencies of rs428253 (p = 0.0191) in EBI3 gene and rs2232365 (p = 0.0307) and rs3761548 (p = 0.0221) in FOXP3 gene were significantly different between the CRS cases and the controls. Furthermore, genotype association analysis showed a significant protective effect only between EBI3_rs428253 (CG/CC; p = 0.029) and CRS after adjustment. Similarly, stratified analysis of CRS risk on category showed rs428253 of the EBI3 gene to play a protective role among both CRSwNP (CG/CC; p = 0.002) and CRSsNP (GG/CC; p = 0.023) subjects. Haplotype analysis of the FOXP3 gene region further indicated that CRS risk was higher in individuals carrying the haplotype GG in rs2294018–rs2232365 block, compared with wild-type AG haplotype, and AG in rs3761548–4824747 block, compared with wild-type CG haplotype. Conclusion The findings of this study suggest that SNPs in FOXP3 and EBI3 genes modify the risk for development of CRS.
