bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T cells; and B cells; NK cells are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of t-lymphocytes referred to as NATURAL KILLER T cells shares some of the properties of this cell type.
