Role of antibodies to self-antigens in chronic allograft rejection: potential mechanism and therapeutic implications.
Significant progress has been made in preventing acute allograft rejection following solid organ transplantation resulting in improved allograft survival. However, long term function still remains disappointing primarily due to chronic allograft rejection. Alloimmune responses primarily defined by the development of antibodies (Abs) to donor mismatched major histocompatibility antigens during t...
متن کاملImmune Responses to Tissue-Restricted Nonmajor Histocompatibility Complex Antigens in Allograft Rejection
Chronic diseases that result in end-stage organ damage cause inflammation, which can reveal sequestered self-antigens (SAgs) in that organ and trigger autoimmunity. The thymus gland deletes self-reactive T-cells against ubiquitously expressed SAgs, while regulatory mechanisms in the periphery control immune responses to tissue-restricted SAgs. It is now established that T-cells reactive to SAgs...
متن کاملLow CD4/CD8 Ratio in Bronchus-Associated Lymphoid Tissue Is Associated with Lung Allograft Rejection
Background. Bronchus-associated lymphoid tissue (BALT) has been associated with lung allograft rejection in rat transplant models. In human transplant recipients, BALT has not been linked to clinically significant rejection. We hypothesize that the immunohistochemical composition of BALT varies with the presence of acute lung allograft rejection. Methods. We retrospectively examined 40 human lu...
متن کاملAcute allograft pancreatitis associated with renal allograft rejection.
Acute allograft pancreatitis is common following simultaneous pancreas and kidney (SPK) transplantation with either bladder or enteric drainage w1,2x. Allograft pancreatitis may be caused by infection, bladder drainage problems, alcohol, drugs and diet w1x. Pancreatic allograft rejection, usually occurring in the context of renal allograft rejection, may cause a syndrome similar to acute allogr...
متن کاملTHE ROLE OF T-L YMPHOCYTE SUBPOPULATION IN RENAL ALLOGRAFT REJECTION
Twenty-two recipients of HLA-nonidentical living related and nonrelated renal allografts were studied for alterations in the relative percentage of OKT4-positive peripheral blood T-cells after transplantation. Characteristic shifts in the ratio of T-helper to T -suppressor/cytotoxic cells (TH/TS-C), but not absolute cell numbers, were demonstrated to correspond with the status of the allog...
