Research progress on the role of macrophages in post-transplantation chronic rejection / 器官移植

ABSTRACT

Organ transplantation is the optimal treatment for end-stage organ failure. Nevertheless, rejection remains an important factor affecting the allograft survival. At present, acute rejection may be effectively treated, whereas no effective interventions are available for post-transplantation chronic rejection. Long-term chronic rejection may lead to graft failure and severely affect long-term survival rate of allografts. In recent years, the role of macrophages in post-transplantation chronic rejection has gradually captivated increasing attention. In this article, main pathological changes of chronic rejection, the diversity and functional differences of macrophages involved in chronic rejection, and the role and mechanism of macrophages in chronic rejection were reviewed, and research progresses on macrophage-related treatment for chronic rejection were summarized, aiming to provide reference for the study of macrophages in post-transplantation chronic rejection.
