Antibodies Reactive to Non-HLA Antigens in Transplant Glomerulopathy

Antibodies reactive to non-HLA antigens in transplant glomerulopathy.

Although T and B cell alloimmunity contribute to transplant injury, autoimmunity directed at kidney-expressed, non-HLA antigens may also participate. Because the specificity, prevalence, and importance of antibodies to non-HLA antigens in late allograft injury are poorly characterized, we used a protein microarray to compare antibody repertoires in pre- and post-transplant sera from several coh...

Transplant Glomerulopathy: The Interaction of HLA Antibodies and Endothelium

Transplant glomerulopathy (TG) is a major cause of chronic graft dysfunction without effective therapy. Although the histological definition of TG is well characterized, the pathophysiological pathways leading to TG development are still poorly understood. Electron microscopy suggests an earlier appearance of TG and suggests that endothelial cell injury is the first sign of the disease. The pat...

Platelet antigens and antibodies in multitransfused patients

Abstract Background and Objectives Following incompatible blood transfusions, anti-HLA and  anti- HPA antibodies may develop and cause various disorders such as post-transfusion purpura, platelet refractoriness, and thrombocytopenia leading to bleeding. The aim of this study was to investigate platelet antigens and antibodies in multi-transfused patients.   Materials and Methods In this desc...

Journal Watch Non-HLA antibodies

The clinical impact of non-HLA specific antibodies either alone or in concert with donor HLA specific antibodies (DSA) has been an intense area of research in kidney transplantation and more recently in thoracic transplantation as well. These non-HLA antigens include receptors expressed by the vascular endothelium such as the G protein coupled receptors (GPCRs), Major Histocompatibility Complex...
