Abstract: Liver transplantation is the optimal treatment for end-stage liver disease and hepatocellular carcinoma, which can significantly improve clinical prognosis and quality of life of patients. However, multiple challenges, such as rejection, immune tolerance, shortage of donor liver, preservation of donor liver, ischemia-reperfusion injury and postoperative complications, etc., limit the efficacy of liver transplantation in clinical practice. Research teams in China have made significant contributions to the basic research related to liver transplantation by making continuous efforts and combining the development of emerging technologies, interdisciplinary integration and other emerging fields. In this article, the frontier progress in the basic research of liver transplantation in 2023 was reviewed, highlighting the progress made by Chinese research teams in the basic research of liver transplantation, aiming to provide reference for promoting the integration of Chinese characteristics into the research of liver transplantation, accelerate the integration of Chinese liver transplantation research with international community, and promote further advancement of liver transplantation in China.
