K cells: killer cells; cells mediating antibody-dependent cell-mediated cytotoxicity (ADCC). They are small lymphocytes without T or B cell surface markers. K cells recognize IgG antibody coating the target cell by means of Fc receptors. Lysis of the target cell is extra-cellular, requires direct cell-to-cell contact, and does not involve complement.
A group of lymphocytes which are able to destroy their targets by antibody-dependent cell-mediated cytotoxicity. They have Fc receptors.Terme :
