MeSH Heading: T-Lymphocytes
Tree Number(s): A11.118.637.555.567.569; A15.145.229.637.555.567.569; A15.382.490.555.567.569
Unique ID: D013601
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D013601
Annotation: general; prefer specifics; subpopulations: coordinate T-LYMPHOCYTE SUBSETS (IM) with specific T-LYMPHOCYTE (IM)
Scope Note: Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
Entry Term(s): T Cell; T Lymphocyte; T-Cells; Thymus-Dependent Lymphocytes
Previous Indexing: Lymphocytes (1966-1972)
See Also: CD4-CD8 Ratio; Immunity, Cellular; Lymphocyte Cooperation
