Survivin and autoimmunity; the ins and outs

مولف: Hamidreza Ebrahimiyana, b, Saeed Aslania, Nima Rezaeib, c, d, Ahmadreza Jamshidia, Mahdi Mahmoudia,

خلاصه: Autoimmunity is a status that immune mechanisms react against self-structure. The immune mechanisms, including cellular and molecular elements have been developed to immune body against foreign invades. Multiple factors such as genetic and epigenetic background, hormonal status, microbiome, and other factors can cause launching the autoreactive responses, in which the immune tolerance breaks and immune mechanisms are against self-antigens. Apoptosis is one of the important mechanisms in maintaining the tolerance and eliminating the autoreactive lymphocyte ... سال انتشار: 2018

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
