T-4 cell

    0.06 sec.
T-4 cell,
a thymus-derived lymphocyte of the body's immune system that activates the humoral immune system (B cells) and destroys or neutralizes cells or substances identified as "nonself." T-4 cells secrete a substance, interleukin-2, which stimulates the activity of natural killer cells, gamma interferon, and suppressor T-8 cells. The human immunodeficiency virus commonly targets T-4 cells, with the result that the body's immune defenses are severely damaged and opportunistic infections are allowed to flourish.
