  Immune system - Wikipedia, the free encyclopedia
A cytotoxic T cell (also known as TC or killer T cell) is a sub-group of T lymphocyte (a type of white blood cell) which is capable of inducing the death of infected somatic or tumor cells; they kill cells that are infected with viruses (or other pathogens), or are otherwise damaged or dysfunctional.
Cytotoxic T cell activation With the exception of some cell types such as non-nucleated cells (including erythrocytes), Class I MHC is expressed by all host cells.
Cytotoxic T cells are activated when their TcR strongly interacts with a peptide-bound MHC class I molecule.

However, most organisms are under constant assult from pathogens, which must be kept in check by the fast-acting innate immune system.
Innate immunity does not recognize specific pathogens, but rather fights general classes of pathogens using less specific defenses.
Pathogens may also be recognized by molecules that distinguish generally between classes of pathogens such as Gram-negative or Gram-positive bacteria.

For instance, the plasma membrane of every nucleated cell contains molecules of a large glycoprotein called the major histocompatibility complex (MHC).
T cells, a group that encompasses cytotoxic T lymphocytes (CTLs), the cells that kill virally-infected cells, contain surface-mounted receptors that they use to determine if a given cell is virally infected by reading the peptides displayed on its MHC molecules.
