A cytotoxic T cell (also known as TC, cytotoxic T lymphocyte, CTL, T-killer cell, cytolytic T cell, CD8 T-cell or killer T cell) is a T lymphocyte (a type of white blood cell) that kills cancer cells, cells that are infected by intracellular pathogens (such as viruses or bacteria), or cells that are damaged in other ways. Most cytotoxic T cells express T-cell receptors (TCRs) that can recognize a sp… WebAbstract: "These volumes, Cytolytic Lymphocytes and Complement: Effectors of the Immune System, originate from the realization that pathways of recognition and killings of foreign targets follow similar routes in the humoral and cellular part of the immune system. In particular, the homology of immunoglobins with the T-cell-MHC-antigen receptor ...

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.
