Cytolytic cd8+ t cell
CD8 + T cells are recognized as T C cells once they become activated and are generally classified as having a pre-defined cytotoxic role within the immune system. However, CD8 + T cells also have the ability to make some cytokines, such as TNF-α and IFN-γ, with antitumour and antimicrobial effects. See more 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 … 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. … 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 T cells go through different stages, depending on the number of times they have been in contact with the antigen.
