Bible DictionaryGlossary of HIV(AIDS)-Related Terms
(T Lymphocytes.) T cells are white blood cells, derived from the thymus gland<!-- (see) -->, that participate in a variety of cell-mediated immune reactions. Three fundamentally different types of T cells are recognized: helper, killer (see killer T cells), and suppressor. They are the immune system's "border police," responsible for finding infected or cancerous cells. The killer T cell receptors (TCR) bind to an infected cell's distress signal -- a combination of one of the cell's own proteins and a tiny fragment of the invader's protein. The bits of foreign protein are made with the help of enzymes inside the invaded cell that chew up the pathogens into protein fragments (peptides), which are then scooped up by the major histocompatibility complex (MHC; see) and carted through the cell membrane.
