Role of autophagy in the pathogenesis of myocarditis / 国际儿科学杂志

ABSTRACT

Myocarditis refers to diffuse or focal inflammatory cell infiltration of the myocardial interstitium and necrosis or degeneration of adjacent myocardial fiber caused by infection or other causes,which is one of the common diseases that cause the death of infants and adolescents.Viral infection is the main pathogenic factor,but the pathogenesis of myocarditis has not yet been fully elucidated.Autophagy is a highly conservative process of self-digestion,which can provide amino acids,ATP and other substances for cells in the state of inflammation or starvation to help cells survive the energy crisis under excessive stimulation.However,excessive autophagy can promote the replication of viruses,which leads to autophagic death.In recent years,some researchers found that autophagy is closely related to the process of viral myocarditis associated with Coxsackie virus B3.The role of autophagy in the pathogenesis of myocarditis is reviewed in this article.
