New insights toward the pathogenesis of ankylosing ; genetic variations and epigenetic modifications

مولف: Mahdi Mahmoudi, Saeed Aslani, Mohammad Hossein Nicknam, Jafar Karami & Ahmad Reza Jamshidi

خلاصه: Ankylosing spondylitis (AS) is a chronic inflammatory autoimmune disease, characterized by typically an axial arthritis. AS is the prototype of a group of disorders called spondyloarthropathies, which is believed to have common clinical manifestations and genetic predisposition. To date, the exact etiology of AS remains unclear. Over the past few years, however, the role of genetic susceptibility and epigenetic modifications caused through environmental factors have been extensively surveyed with respect to the pathogenesis of AS, resulted ... سال انتشار: 2017

Abstract: Background/objective: Genetic factors seem to play an important role in the pathogenesis ofulcerative colitis (UC). Genome wide association studies showed a highly significant associationbetween interleukin 23 receptor (IL23R) single nucleotide polymorphisms (SNPs) and Crohn’sdisease; however, there are contrary results regarding the disease-modifying effects of IL23Rvariants in UC. This study was performed in a group of patients with UC to test the possible roleof IL23R SNPs in conferring susceptibility or protection ... سال انتشار: 2014
