Abstract: Background: Inappropriate activation or blockage of inhibition of the complement system could cause tissue damage in autoimmune diseases particularly rheumatoid arthritis (RA). CD55 and CD59 are proteins with complement regulatory (Creg) properties that ensure cell and tissue integrity when this system is activated. Objective: The aim of this study was to evaluate the expression of CD55 and CD59 complement ... إقراء المزيد

Vitiligo is an acquired cutaneous disorder characterized by progressive and selective destruction of melanocytes. Although, the exact etiology of vitiligo is still obscure, autoimmunity is strongly implicated in its pathogenesis. The aim of this study was to evaluate the immunological alterations in the peripheral lymphocytes in patients with vitiligo and their possible immunomodulation by narrowband ultraviolet B phototherapy. The study ... إقراء المزيد
