عنوان انگلیسی TIM-3 Rs10515746 (A/C) and Rs10053538 (C/A) Gene Polymor-phisms and Risk of Multiple Sclerosis
چکیده انگلیسی مقاله Background: Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) caused by autoreactive T cells against myelin antigens. T-cell immunoglobulin mucin -3 (TIM-3) is a negative regulator glycoprotein expressed by a range of immune cells, including, Th1 cells, activated CD8+ T cells and in a lower level on Th17 cells. A defect in TIM-3 regulation has been shown in multiple sclerosis patients. In humans, several single nucleotide polymorphisms (SNPs) have been identified in the TIM-3 gene and are associated with inflammatory diseases. The aim of this study was to analyze the association between TIM-3 -574A>C and -1516 C>A SNPs in the promoter region, and susceptibility to MS. Methods: DNA samples from 102 patients and 102 healthy controls were genotyped using RFLP-PCR method. Results: In this case-control study, analysis of the alleles and genotypes revealed a significant higher frequency of C/C and lower frequency of A/C genotypes for -574 locus of TIM-3 gene in MS patients ( P =0.0002). We also found that C/C genotype for locus of -1516 increased in MS patients, while A/C genotype decreased ( P =0.012). Allele C of -574C/C and -1516 C>A SNPs were also more frequent in MS patients ( P =0.036 and 0.0027 respectively). Conclusion: -574 A>C and -1516 C>A SNPs in the promoter region of TIM3 gene may affect the disease susceptibility.
