====== T cell ======

T-cells are a type of [[white blood cell]] that plays a crucial role in the [[immune response]] by recognizing and destroying abnormal cells, including cancer cells.

[[T-cell]]s or T [[lymphocyte]]s are a type of [[lymphocyte]] (itself a type of [[white blood cell]]) that play a central role in cell-mediated [[immunity]]. They can be distinguished from other lymphocytes, such as [[B cell]]s and [[natural killer cells]] (NK cells), by the presence of a [[T-cell receptor]] (TCR) on the [[cell surface]]. They are called T cells because they mature in the [[thymus]] (although some also mature in the [[tonsil]]s).
----
T cells are generated in the Thymus and are programmed to be specific for one particular foreign particle ([[antigen]]). Once they leave the [[thymus]], they circulate throughout the body until they recognize their [[antigen]] on the surface of [[antigen-presenting cells]].

===== Subsets =====

There are several subsets of T cells, each with a distinct function.

There are 3 main types of T cells: cytotoxic, helper, and regulatory. Each of them has a different role in the immune response
