title: [Genetic relationships between the HL-A system, the blood group systems (Rh, ABO) and the immune reactivity].
abstract: The authors examined in immunized healthy persons the correlations between the ability of immune response, the value of their different immunological parameters, and the HL-A blood-group antigens by computer analysis. Immune reactivity showed mosaic-like correlation against the HL-A system. The most definite negative correlation was noticed between the HL-A 3 and 7 antigens and the cytotoxic activity of lymphocytes. Remarkable and definite correlation was found between the Rh system and immune reactivity. The level of the natural antibodies, the immunoglobulins and the functions of lymphocytes were generally decreased in males in comparison to females.
