Immunologically triggered reaction occurring in a transplanted organ or tissue, leading to progressive destruction and finally failure of the transplanted organ occurring two months to many years after transplantation.
Note: In contrast, hyperacute rejection caused by preformed antibodies starts within minutes after organ transplantation, and acute rejection occurs within 2 to 60 days.
