T cell, [Immunol.]
- Immunologyany of several closely related lymphocytes, developed in the thymus, that circulate in the blood and lymph and orchestrate the immune system's response to infected or malignant cells, either by lymphokine secretions or by direct contact: helper T cells recognize foreign antigen on the surfaces of other cells, then they stimulate B cells to produce antibody and signal killer T cells to destroy the antigen-displaying cells;
subsequently suppressor T cells return the immune system to normal by inactivating the B cells and killer T cells. Also called T lymphocyte.
