Cytolytic lymphocyte
WebDec 3, 1999 · The gene encoding perforin, an important mediator of lymphocyte cytotoxicity, has been mapped to 10q22 ( 8 ), near one of the previously identified FHL-linked loci ( 9, 10 ). Thus, perforin deficiency may play a role in the pathogenesis of FHL. Unlike patients with FHL, perforin knockout mice are generally healthy when maintained … WebThis protein is found in immune cells (lymphocytes) called T cells and natural killer (NK) cells, which destroy other cells. Perforin is involved in the process of cell destruction (cytolysis) and the regulation of the immune system. Perforin is a major component of structures called cytolytic granules within T cells and NK cells.
