| Description |
The T lymphocyte activation pathway is triggered when a T cell encounters its cognate antigen, coupled to an MHC molecule, on the surface of an infected cell or a phagocyte. T cells contribute to immune defenses in two major ways: some direct and regulate immune responses; others directly attack infected or cancerous cells. |
