Natural killer cells (NK cells) are a component of the innate immune system that does not directly attack invading microbes. Rather, NK cells destroy compromised host cells, such as tumor cells or virus-infected cells, recognizing such cells by a condition known as missing self..
This 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.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.
