Epigenetic involvement in etiopathogenesis and implications in treatment of systemic lupus erythematous

مولف: Arron Munggela Foma1 • Saeed Aslani1, 2 • Jafar Karami2, 3 • Ahmadreza Jamshidi2 • Mahdi Mahmoudi

خلاصه: Abstract Background Recent researches in the field of genetics have extended our knowledge through the discovery of genetic factors associated with autoimmune diseases (AID). Genetics by itself, however, cannot elucidate all the uncertainties encountered in the etiopathology of AID. On the other hand, incomplete harmony in the prevalence of AID in identical twins suggests that non-genetic factors may play an important role in determining the disease susceptibility. Besides, epigenetics, which is defined by changes in gene expression without a corresponding change ... سال انتشار: 2017
