title: Influence of HLA-D/DR antigen disparity in CTL generation in vitro.
abstract: This report describes the influence of HLA-D/DR antigen disparity upon the level of cytotoxicity in allogeneic in vitro cultures. Allogeneic cultures, between unrelated HLA-D/-DR full house donors, tested in CML gave three different levels of cytotoxicity, termed weak, intermediate and strong cytotoxicity. HLA-D/-DR compatibility predicts weak cytotoxicity and two HLA-B antigen incompatibility predicts strong cytotoxicity. On the contrary, HLA-A antigens have no major influence upon the strength of cytotoxicity. Accepting that the MLC/CML reaction is an in vitro parallel to the in vivo transplantation of allogeneic tissue, the observations are in accordance with the results of HLA-D/-DR matching for graft survival in human renal transplantation.
