Killer-cell inhibitory receptors inhibit cytolysis when natural killer cells encounter cells bearing HLA class I molecules.^1,2 This phenomenon explains the preferential killing by natural killer cells of tumor cells with reduced expression of HLA class I molecules.³ This finding is the basis of the "missing self" model, in which the HLA class I allele lost by the tumor cells is not available to inhibit the killer cell's lytic machinery.

Different types of killer-cell inhibitory receptors have distinct specificity for HLA-A, B, C, and E antigens.^1,4 In addition, some natural killer cells also possess receptors that induce lysis of cells expressing . . . [Full Text of this Article]
