MSH: 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.,CSP: type of cytotoxic leukocytes which attack and kill virus-infected or neoplastic cells independent of antibody coating or MHC restriction; may be derived from lymphocytes or monocytes.,NCI: A type of immune cell that has granules (small particles) with enzymes that can kill tumor cells or cells infected with a virus. A natural killer cell is a type of white blood cell.,NCI: Natural killer cells are cells that resemble large granular lymphocytes. They do not express markers of either T or B cell lineage. They are positive for CD16, CD56, and CD 94. T
