Deletion of Smad3 improves cardiac allograft rejection in mice
T cells play a critical role in acute allograft rejection. TGF-β/Smad3 signaling is a key pathway in regulating T cell development. We report here that Smad3 is a key transcriptional factor of TGF-β signaling that differentially regulates T cell immune responses in a mouse model of cardiac allograft rejection in which donor hearts from BALB/c mice were transplanted into Smad3 knockout (KO) and ...
متن کاملUpregulation of COX-2 during cardiac allograft rejection.
BACKGROUND The hypothesis that cyclooxygenase-2 (COX-2) is involved in the myocardial inflammatory response during cardiac allograft rejection was investigated using a rat heterotopic abdominal cardiac transplantation model. METHODS AND RESULTS COX-2 mRNA and protein in the myocardium of rejecting cardiac allografts were significantly elevated 3 to 5 days after transplantation compared with s...
متن کاملMechanisms of chronic cardiac allograft rejection.
Chronic rejection in the form of cardiac allograft vasculopathy is one of the major factors that affects long-term graft and patient survival after heart transplantation. Whereas multiple factors contribute to the development of cardiac allograft vasculopathy, immunologic mechanisms play the predominant role in the chronic rejection process, because both alloimmune and autoimmune responses are ...
متن کاملAntibody Mediated Rejection of the Cardiac Allograft
Antibody mediated rejection (AMR), also known as B-cell mediated rejection or humoral rejection, of the cardiac allograft was first clinically described in the late 1980’s (Herskowitz et al., 1987) followed shortly thereafter by pathologic evidence to support a unique rejection process apart from cellular mechanisms (Hammond et al., 1989). This is in contrast to the progression of knowledge reg...
متن کاملIndoleamine 2,3-dioxygenase gene transfer prolongs cardiac allograft survival.
Cells that express indoleamine 2,3-dioxygenase (IDO), the rate-limiting enzyme in the catabolism of tryptophan, suppress T cell responses and promote immunological tolerance. However, their role in solid organ transplantation is incompletely understood. We analyzed T cell responses to allogeneic dendritic cells (DCs) genetically modified to express the gene encoding IDO in vitro and IDO gene tr...
