Abstract
PURPOSE Multiple sclerosis (MS) is an autoimmune disease characterized by inflammatory demyelinating lesions in the white matter of the central nervous system. Myocyte enhancer factor 2 (MEF2) family genes play important roles in the immune response. This study focuses on the relationship between MEF2 family gene polymorphisms and MS. METHODS A total of 174 MS patients and 120 healthy controls were recruited. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to analyze the gene polymorphisms of MEF2D and MEF2C. In addition, peripheral blood was collected and leukocytes were isolated. The transcription level of MEF2D in the two groups of samples was detected with quantitative real time polymerase chain reaction (qRT-PCR). RESULTS We found that the C allele frequency and CC genotype frequency of rs2274316 in MEF2D were significantly higher in MS patients. The C allele and CT genotype distribution for rs3790455 were significantly more frequent in MS patients. Female patients showed higher CC genotype frequency of rs2274316. The genotype frequency distribution of rs2274316 and rs3790455 were not related to onset age and phenotype of MS patients. In addition, this study also proved that MEF2D was significantly overexpressed in the peripheral blood leukocytes of MS patients. The transcription level of MEF2D was significantly higher in patients with CC genotype of rs2274316. CONCLUSION These findings suggest rs2274316 and rs3790455 of MEF2D gene are potential genetic risk factors for MS in Chinese population. The transcription level of MEF2D is also associated with susceptibility to MS and MEF2D gene polymorphisms.

Abstract
Cluster of differentiation (CD)1 molecules are a highly conserved family of MCH-like transmembrane glycoproteins that bind lipid and glycolipid antigens and present a diverse range of microbial and self-glycolipids to antigen-specific T cells. The current study aimed to find out the impact of CD1A and CD1D polymorphisms on pulmonary tuberculosis (PTB). This case-control study encompassed 172 PTB patients and 180 healthy subjects. Genotyping of CD1A and CD1D variants was achieved using the polymerase chain reaction restriction fragment length polymorphism method. The results revealed that CD1A rs411089 variant significantly increased the risk of PTB in recessive model [odds ratio (OR)=2.71, 95% confidence interval (CI)=1.38-5.57, CC vs. TT+TC, P=0.005]. CD1D rs859009 polymorphism significantly reduced the risk of PTB in heterozygous codominant (OR=0.50, 95% CI=0.29-0.86, P=0.011, GC vs. GG) and dominant (OR=0.53, 95% CI=0.31-0.88, P=0.019, GC+CC vs. GG) inheritance model. The CD1A rs366316, CD1D rs973742 and CD1D rs859010 were not associated with the risk/protection from PTB (P>0.05). The results of the present study suggest that CD1A rs411089 and CD1D rs859009 but not CD1A rs366316, CD1D rs973742 and CD1D rs859010 polymorphisms are associated with PTB in a sample of the Iranian population. Further investigation with different ethnicities and larger sample sizes are necessary to certify the findings of the present study.

Abstract
CD1 and immunoglobulin G Fc receptor (FcγR) genes have been proposed to be involved in the pathogenesis of Guillain-Barré syndrome (GBS). However, results of different studies are conflicting. This meta-analysis aimed to systematically examine the association between CD1 and FcγR gene polymorphisms and GBS. A comprehensive literature search through PubMed, EmBase, ScienceDirect, and Cochrane Library was performed to identify all eligible studies. The strength of association was assessed by pooled odds ratios (ORs) and corresponding 95% confidence intervals (95% CI) in allelic, dominant, recessive, homozygous and heterozygous genetic models. Four case-control studies about polymorphisms of exon 2 in CD1A and CD1E genes and GBS risk and five studies (six cohorts) about FcγR gene polymorphisms and GBS risk were included in this meta-analysis. The association between exon 2 of CD1E gene polymorphism and GBS was marginally significant in Caucasians in allelic model (OR = 1.193, 95% CI = 1.001-1.423, P = 0.049). FcγRIIA gene polymorphism was significantly associated with GBS risk in Caucasians under allelic model (OR = 1.553, 95% CI = 1.018-2.368, P = 0.041) and dominant model (OR = 1.320, 95% CI = 1.027-1.697, P = 0.030). However, no significant association was found between polymorphisms in exon 2 of CD1A, FcγRIIIA and FcγRIIIB genes and GBS susceptibility. This meta-analysis suggested that FcγRIIA gene polymorphism may contribute to GBS risk in Caucasians and revealed a certain trend toward significance in the association of exon 2 of CD1E gene with GBS in Caucasians. Further studies with larger sample size are required to validate these results.

Abstract
CD1 molecules are specialized in capturing and presenting lipids and glycolipids to distinct subsets of T and NKT cells. Glycolipid presentation could play a significant role in the immune response against microbial infections. There are five closely linked CD1 genes in humans, named CD1A, B, C, D, and E, which all show a limited polymorphism. In this study, exon 2 polymorphisms of CD1A, CD1D and CD1E were investigated and allele, genotype and haplotype frequencies of these loci were reported in a Moroccan population. A comparison with allele, genotype and haplotype frequencies observed in other geographic areas was also performed. Results confirmed the presence of ethnic differences in CD1 polymorphism, mainly in CD1D (in this population two additional CD1D variant alleles, CD1D(∗)03 and CD1D(∗)04, were described) and E genes. These data could be useful to evaluate a possible pathogenetic role of CD1 in diseases. Increasing the knowledge in this field may offer possibilities for the development of new immunotherapeutic approaches.

Abstract
Recently, protein tyrosine phosphatase nonreceptor 22 (PTPN22) C1858T polymorphism has been identified as a susceptibile gene for type 1 diabetes (T1D), but studies are inconsistence, In order to assess the association between PTPN22C1858T polymorphism and T1D based on different ethnicities, a meta-analysis was performed, including 26 studies, total of 16,240 patients and 17,997 controls. Meta-analysis was performed on T versus C, T/T+T/C versus C/C (dominant model) and T/T versus T/C+C/C (recessive model) in a fixed/random effects model. The results indicated an association between the PTPN22 C1858T polymorphism and T1D in all subjects. The overall odds ratio (OR) of T versus C using the fixed effects model was 1.948 (95% CI = 1.859∼2.041, P < 0.001). After stratification by ethnicity, analysis revealed that the PTPN22 C1858T polymorphism T allele was significantly associated with T1D in Europeans, Americans (OR = 1.946, 95% CI = 1.852~2.045, P < 0.001; OR = 1.946, 95% CI = 1.690~2.242, P < 0.001, respectively). Meta-analysis of the T/T+T/C genotype and the T/T genotypes showed the same results as that shown by the PTPN22 C1858T polymorphism T allele. This meta-analysis suggests a possible association between the PTPN22 C1858T polymorphism and T1D, especially in European and American populations.

[PMID: 22236374 DOI: 10.1016/j.jneuroim.2011.12.003] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2011] [Revised: 11/14/2011] [Accepted: 12/03/2011] [Indexed: 11/25/2022]
Abstract
BACKGROUND AND OBJECTIVES The findings on the associations between potential genetic variants and risk of Guillain-Barré syndrome (GBS) are controversial. We conducted a meta-analysis for candidate genes to provide the evidences for the current understanding of the genetic association with GBS. METHODS We searched relevant studies without language restriction in PubMed, Embase and Cochrane library through May 2011. The strengths of the associations between genetic variants and GBS risk were estimated by odds ratios (ORs) with 95% confidence intervals (CIs). Random-effects models or fixed effects model was applied based on the heterogeneity test. RESULTS We identified 12 case-control studies involving 1,590 GBS cases and 2,154 controls for the analysis. Because of limited eligible data, our meta-analysis specifically focused on 6 genetic variants of 3 candidate genes, TNF-α, FcγR and CD1. We found that TNF-α 308 G/A polymorphism was significantly associated with the risk of GBS in the overall population (GG+GA vs. AA: OR=0.32, 95%CI=0.16-0.62; GG vs. AA: OR=0.36, 95%CI=0.19-0.68). Subgroup analysis further provided evidence of significant association between TNF-α 308 G/A and risk of the GBS in Asian population (GG+GA vs. AA: OR=32, 95%CI=0.11-0.93; GG vs. AA: OR=0.32, 95%CI=0.15-0.68). In addition, we did not observe significant associations between FcγRIIA R/H, FcγRIIIA F/V, FcγRIIIB NA1/NA2, CD1A 1/2 and CD1E 1/2 polymorphisms and susceptibility for developing GBS. CONCLUSIONS Our findings showed that TNF-α 308A allele might be a moderate risk factor for GBS. However, the results should be interpreted with caution due to the limited number of studies available.
