Abstract

Human natural killer (NK) cells with the CD3- CD16+ phenotype recognize allospecificities on normal T-cell blasts. The NK-defined specificity 1 (NK- 1) is recessively inherited and has been mapped to the major histocompatibility complex between the complement gene cluster and HLA-A. A gene for NK-1, however, has not been identified. Here we demonstrate that NK- 1 and the recently defined NK specificity 2 (NK-2) are reciprocally associated with homozygosity for a diallelic polymorphism at amino acid positions 77 and 80 in the putative peptide-binding site of HLA-C (P < 10- 5). NK-cell recognition of allogeneic cells may, therefore, be controlled by HLA-C itself or by a closely linked gene(s), which dominantly prevents (resistance alleles) or recessively permits (susceptibility alleles) recognition of still-unknown target determinants.
