Natural killer cells or NK cells are a type of cytotoxic lymphocyte critical to the innate immune system.his role of NK cells is critical to immune success particularly because T cells are unable to recognize pathogens in the absence of surface antigens. Tumor cell detection results in activation of NK cells and consequent cytokine production and release.
Natural killer cell: A cell that can react against and destroy another cell without prior sensitization to it. Abbreviated NK cell. NK cells are part of our first line of defense against cancer cells and virus-infected cells. NK cells are small lymphocytes that originate in the bone marrow and develop without the influence of the thymus. An NK cell attaches to a target cell, releases chemicals that breach its cell wall, and causes it to lyse (break up).
