ABSTRACT
Retinoic acid-inducible gene I is an important intracellular pattern recognition receptor in antiviral innate immune responses.After recognition of viral RNA, retinoic acid-inducible gene I triggers antiviral signaling pathways which induce the production of interferons and proinflammatory cytokines.Kidney is an important organ of human body.The occurrence of kidney diseases in childhood has a great impact on children's growth and daily life.Recent studies have shown that retinoic acid-inducible gene I can participate in inflammation and immune responses of kidney, and promote the occurrence and progression of kidney diseases.This article reviews the research progress of retinoic acid-inducible gene I in kidney diseases, and discusses its application prospect as a biomarker and therapeutic target of kidney diseases.
