Research and application progress in adoptive re-transfusion of regulatory cells in organ transplantation / 器官移植

ABSTRACT

Rejection and adverse reactions caused by long-term use of immunosuppressants severely affect the survival rate and quality of life of organ transplant recipients. Immune tolerance induction plays a key role in improving the survival rate and quality of life of organ transplant recipients. In recent years, tremendous progress has been achieved in adoptive re-transfusion of regulatory cells. In this article, research progress in regulatory T cell (Treg), myeloid-derived suppressor cell (MDSC) and regulatory B cell (Breg) in animal experiment and clinical application was reviewed, and the main clinical problems of adoptive re-transfusion of regulatory cells, the application of chimeric antigen receptor Treg and the concept of cell therapy in immune evaluation were summarized, aiming to deepen the understanding of regulatory cell therapy, promote the application of regulatory cells in immune tolerance of organ transplantation, and improve clinical efficacy of organ transplantation and the quality of life of recipients.
