Research progress on the role of tolerogenic dendritic cells in immune tolerance of liver transplantation / 器官移植

ABSTRACT

Rejection after liver transplantation severely affects the survival of recipients. Long-term use of immunosuppressants is an important approach to prevent rejection, whereas it may cause toxic effects and increase the risk of adverse events such as systemic infection and tumor recurrence, etc. Therefore, before successful liver transplantation, how to induce individual immune tolerance of recipients and achieve complete or early withdrawal of postoperative immunosuppressants remains to be investigated by practitioners of organ transplantation. In recent years, certain progresses have been made in the mechanism of immune tolerance induced by tolerogenic dendritic cells in liver transplantation, and preliminary outcomes have been obtained in clinical trials. In this article, basic research and clinical application progress in the characteristics of tolerogenic dendritic cells, the mechanism underlying participating in liver immune microenvironment remodeling, and inducing immune tolerance in liver transplantation were reviewed, aiming to provide reference for the application of tolerogenic dendritic cells in immune tolerance of liver transplantation.
