Elevated natural killer cytotoxicity in HLA-B8 and HLA-DR3-positive individuals.
Increased natural killer cytotoxicity in persons positive for HLA-B8 and HLA-DR3 has been found. It is suggested that linkage disequilibrium between the genes coding for HLA-B8 and HLA-DR3 may have evolved as a result of strengthened immunological surveillance in individuals bearing them, as decrease in the frequency of both these antigens has recently been reported in patients with tumours.
