Abstract
Adenosine, as an endogenous purine nucleoside, is widely distributed in various tissues and organs of the body. It binds to adenosine receptors to regulate a variety of important biological processes. Adenosine 2A receptors have a close relationship with the occurrence and development of various clinical diseases. This article reviews the research progress of adenosine 2A receptors in non-alcoholic fatty liver disease, acute immune hepatitis, liver ischemia-reperfusion injury, liver fibrosis, etc., in order to provide new research strategies for the prevention and treatment of these diseases.
