NK cell activating receptors and tumor recognition in humans

C Bottino et al. Curr Top Microbiol Immunol. 2006.

Abstract

Natural killer (NK) cells have been known for many years as the lymphocyte subset characterized by the highest cytolytic potential against virus-infected and tumor-transformed cells. A surprisingly high number of surface molecules have been recognized that regulate human NK cell function. These include MHC-specific inhibitory receptors, which impair NK cells' ability to attack normal self-tissues, and activating receptors and coreceptors that allow them to recognize and kill transformed cells. The recent identification of some of the cellular ligands specifically recognized by these receptors/coreceptors contributes to elucidation of the mystery of the role played by NK cells in immune responses.
