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. … See more The immune system must recognize millions of potential antigens. There are fewer than 30,000 genes in the human body, so it is impossible to have one gene for every antigen. Instead, the DNA in millions of white … See more When exposed to infected/dysfunctional somatic cells, TC cells release the cytotoxins perforin, granzymes, and granulysin. Through the action of perforin, granzymes enter … See more • Biology portal • CTL-mediated cytotoxicity • CD4 T cells See more • Media related to Cytotoxic T cells at Wikimedia Commons • T-cell Group - Cardiff University See more T cells go through different stages, depending on the number of times they have been in contact with the antigen.
