linfocitos citolíticos naturales
Scope note: Linfocitos derivados de la médula ósea que poseen propiedades citotóxicas, típicamente dirigidas contra las células alteradas o infectadas por virus. A diferencia de las CÉLULAS T y las CÉLULAS B, las CÉLULAS NK no son específicas de antígenos. La citotoxicidad de las células asesinas naturales viene determinada por la señalización colectiva de una serie de RECEPTORES DE LA SUPERFICIE CELULAR inhibidores y estimuladores. Un subconjunto de LINFOCITOS T, denominadas CÉLULAS T ASESINAS NATURALES, comparten algunas propiedades de este tipo celular.

Scope note: 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.
Annotation: do not confuse with NATURAL KILLER T-CELLS; if subpopulations are discussed, coordinate IM with LYMPHOCYTE SUBSETS (IM)
