Abstract

Antibodies to DR antigens were detected using serological and immunochemical tests in sera from rabbits and goats immunized with cultured human B-lymphoid cells mixed with an anti-T-cell xenoantiserum or with partially purified DR antigens. After absorption with human red blood cells, cultured melanoma cells, and/or T-lymphoid cells, DR xenoantisera become specifically cytotoxic to B lymphocytes. Three out of nine sera tested with a panel of T-depleted peripheral lymphocytes and chronic lymphocytic leukemia cells showed correlation with DR alloantisera submitted to the Seventh International Histocompatibility Workshop. Although the correlation coefficients were lower than those obtained with DR alloantisera, the results obtained suggest that DR xenoantisera may recognize allotypic specificities.
