Definition
English
:
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.
