Synonyms:	T lymphocyte activation via T cell receptor contact with antigen bound to MHC molecule on antigen presenting cell, T-cell activation via T cell receptor contact with antigen bound to MHC molecule on antigen presenting cell, T-lymphocyte activation via T cell receptor contact with antigen bound to MHC molecule on antigen presenting cell
Definition:	The change in morphology and behavior of a mature or immature T cell resulting from exposure to an antigen for which its T cell receptor is specific bound to an MHC molecule on an antigen presenting cell, leading to the initiation or perpetuation of an immune response.
