Antibodies to donor B lymphocytes and mixed lymphocyte culture blocking in cadaveric renal transplantation.
In 33 renal allograft recipient-donor pairs, B and T lymphocyte complement-dependent cytotoxicity crossmatches and mixed lymphocyte culture (MLC) blocking experiments were performed and the results were correlated with graft outcome. MLC blocking particularly in the unidirectional culture against donor-stimulating cells, was highly correlated with the presence of complement-dependent cytotoxicity antibodies against donor B lymphocytes. Grafts in both MLC blocking and B lymphocyte crossmatch-positive groups fared equally as well as those without positive tests. No difference in graft outcome was noted when the presence or absence of MLC blocking was examined in relationship to positive or negative B lymphocyte complement-dependent cytotoxicity crossmatching.
