CTRP Terminology Natural Killer Cell 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. Natural Killer Cell killer cell NK Cell NK Natural_Killer_Cell CDISC NATURAL KILLER CELL Natural Killer Cell Cells resembling large granular lymphocytes that do not express markers of either T or B cell lineage. These cells express Fc receptors for IgG and can kill target cells using antibody-dependent cell-mediated cytotoxicity. They can also use perforin to kill cells in the absence of antibody, and may occur without previous sensitization. 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. These cells do possess Fc receptors for IgG and can kill target cells using antibody-dependent cell-mediated cytotoxicity. They can also use perforin to kill cells in the absence of antibody and killing may occur without previous sensitization.
