WebCytotoxic T cells attempt to identify and destroy infected cells before the pathogen can replicate and escape, thereby halting the progression of intracellular infections. They also support NK lymphocytes to destroy early cancers. WebCytotoxic T cells (T C) are the key component of the cell-mediated part of the adaptive immune system and attack and destroy infected cells. T C cells are particularly important in protecting against viral infections; this is because viruses replicate within cells where they are shielded from extracellular contact with circulating antibodies.
