title: [Differences in the capacity of HLA sera to react with T- and B-lymphocyte populations].
abstract: A study was made of perculiarities attending the reaction of the HLA-sera with the T- and B-lymphocytes isolated from human blood. Lymphocytes were separated by removal of one of the cell subpopulation. T-lymphocytes were separated by the method of rosette-formation with sheep erythrocytes, with subsequent gradient density centrifugation. B-lymphocytes were separated similarly with the aid of rosette-formation with allogenous Rh-positive erythrocytes sensitized with Rh-sera with incomplete antibodies, and also sorption of B-lymphocytes on synthetic fiber. The cytotoxic activity of HLA-sera decreased after the removal of B-cells. But removal of T-lymphocytes was not accompanied by any reduction in the lymphocytotoxic activity. It is suggested that B-lymphocytes contained on their surface more HLA determinants than T-lymphocytes.
