However, in studies with NOD mice carrying a null mutation at the beta 2-microglobulin (beta 2-mu) locus and thus lacking major histocompatibility complex class I molecules and CD8+ T cells, it was found that they did not develop diabetes.[27]. Finally, when the specific immune response is triggered, these naive and memory T cells are activated, giving rise to effector T cells that have the capacity to kill pathogens or tumor cells.[6][7]. [20] In some studies with mice, the injection with CXCR5+CD8+T cells show a significative decrease of HBsAg. 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.[1].

For this reason, T-cell receptors were difficult to isolate in the laboratory and were not identified until 1983. [4] T cells possess a wide functional plasticity after recognising infected or transformed cells, as they are able to produce cytokines (IFN-, TNF-, IL-17) and chemokines (IP-10, lymphotactin), trigger cytolysis of target cells (perforins, granzymes), and interact with other cells, such as epithelial cells, monocytes, dendritic cells, neutrophils and B cells. T-cells play a large role in our fight against cancer. It can be very confusing to talk about T-cells, especially when talking about cancers such as lymphoma, so we'll look at ways that T-cells work to fight cancer and how they may be affected by cancer.
