摘要
Different kinds of human chronic diseases may develop the mechanism of autoimmune diseases.As a group of disorders,in the Western world autoimmunity possess as the third most prevalent morbidity and mortality.However,the mechanism of most autoimmune diseases is still under investigation.Viral infection is the principal factor involved in the induction of autoimmune diseases other than genetic factors and cytokine activity.Different mechanisms have been proposed by which viral infection might interrupt tolerance to self and induce autoimmune cascade which eventually leads to the destruction of a specific type of cell or a whole-body organ.The autoimmune attack can be understood through the different immune systems and other possible mechanisms such as molecular mimicry,bystander activation and epitope spreading.In addition to genetic and viral factors,other environmental factors are also involved including bacterial,parasitic and fungal infections.However,different animal models have been studied which provide strong evidence that viruses induced AIDs as well as accelerated and increased lesions in conditions where self-tolerance is interrupted.In the current review,we discussed the virus-induced autoimmunity and the molecular mechanism which is associated with this phenomenon.Here we also discussed the different viruses such as rubella virus,enteroviruses,measles virus,human T-lymphotropic virus type1,human cytomegalovirus,human herpes virus-6,Epstein-Barr virus,rotavirus and some other viruses which modulate the development of AIDs.
