Abstract: Antibody-mediated rejection (AMR), also known as humoral rejection, is an immune injury caused by rejection involved with multiple humoral immune effectors, such as antibodies and complements, etc. AMR plays a pivotal role in hyperacute, acute and chronic rejection. In this article, the basic definition of AMR, the research progress and major achievements on AMR pathology according to Banff classification on allograft pathology (Banff classification), and main pathological characteristics of AMR in renal allograft were reviewed, aiming to provide reference for accurate diagnosis and timely treatment of AMR, and guarantee the long-term survival of renal graft and recipients.
