چکیده

Systemic sclerosis (SSc) is a fibrotic and autoimmune disease characterized clinically by skin and internal organ fibrosis and vascular damage, and serologically by the presence of circulating autoantibodies. Although etiopathogenesis is not yet well understood, the results of numerous genetic association studies support genetic contributions as an important factor to SSc. In this paper, the major genes of SSc are reviewed. The most recent genome-wide association studies (GWAS) are taken into account along with robust candidate gene studies. The literature search was performed on genetic association studies of SSc in PubMed between January 2000 and March 2014 while eligible studies generally had over 600 total participants with replication. A few genetic association studies with related functional changes in SSc patients were also included. A total of forty seven genes or specific genetic regions were reported to be associated with SSc, although some are controversial. These genes include HLA genes, STAT4, CD247, TBX21, PTPN22, TNFSF4, IL23R, IL2RA, IL-21, SCHIP1/IL12A, CD226, BANK1, C8orf13-BLK, PLD4, TLR-2, NLRP1, ATG5, IRF5, IRF8, TNFAIP3, IRAK1, NFKB1, TNIP1, FAS, MIF, HGF, OPN, IL-6, CXCL8, CCR6, CTGF, ITGAM, CAV1, MECP2, SOX5, JAZF1, DNASEIL3, XRCC1, XRCC4, PXK, CSK, GRB10, NOTCH4, RHOB, KIAA0319, PSD3 and PSOR1C1. These genes encode proteins mainly involved in immune regulation and inflammation, and some of them function in transcription, kinase activity, DNA cleavage and repair. The discovery of various SSc-associated genes is important in understanding the genetics of SSc and potential pathogenesis that contribute to the development of this disease.

P 153: Neuroinflammation in Multiple Sclerosis

Multiple sclerosis (MS) is a complex disease which is correlated with increasing inflammatory factors, demyelination and axonal loss. In this auto-immune disease, Neuroinflammation is mediated by different types of T cells with macrophage/microglial activation and B cells involvement that interact in a collaborative manner. Focal inflammation is the main cause for the onset of relapses and coul...

O 1: The Effects of Vitamin D Supplementation on the T cell Compartment in Multiple Sclerosis

Multiple sclerosis (MS) is a complex neurological disease and its prevalence is about 2 million in the world. Neuroinflammation plays a key role in MS. Vitamins are essential nutrients that have effective role on immune system including activation of lymphocyte and differentiation of T-helper cell. Vitamin D is a micronutrient that is effective on immune function. Deficiently of Vitamin D is a ...

our goal in this paper is to describe and compare basic immunopathologic pattern of common demyelinating disorder, that is very important to choose the best treatment. The most common disorders are multiple sclerosis, neuromyelitis optica,Anti MOG associated disease,ADEM and autoimmune encephalitis. ADEM consists of ‘‘sleeves’’ of demyelination centered on small, engorge...

CTLA4 Gene Variants in Autoimmunity and Cancer: a Comparative Review

Gene association studies are less appealing in cancer compared to autoimmune diseases. Complexity, heterogeneity, variation in histological types, age at onset, short survival, and acute versus chronic conditions are cancer related factors which are different from an organ specific autoimmune disease, such as Grave’s disease, on which a large body of multicentre data is accumulated. For years t...

Investigation of FcγRIIA and FcγRIIIA Polymorphism in Multiple Sclerosis: A Case Control Study

Background: Multiple Sclerosis (MS), the most common demyelinating disease of the CNS, is immunologically mediated in genetically susceptible individuals. Receptors for the Fc fragment of IgG (FcγR) might induce inflammatory responses through linking the humoral and cellular immune responses by targeting immune complexes to effector cells. Polymorphisms in some FcγR genes are associated with va...

ژنتیک دیابت نوع یک: بررسی نقش ژنTNF-

Background: Type 1 diabetes (T1DM) is an organ specific auto-immune disease, which is resulted by selective destruction of  islet cells. Insulitis as the initial event prior to T1DM development is featured mainly by lymphocytic infiltration, that may recede frequently leading to healthy state (benign insulitis). Among the issues that govern which of these outcome lie ahead in insulitis are the...
