Th1 Cells

**Definition:** A subset of helper-inducer T-lymphocytes which synthesize and secrete INTERLEUKIN-2; INTERFERON-GAMMA; and INTERLEUKIN-12. Due to their ability to kill antigen-presenting cells and their lymphokine-mediated effector activity, Th1 cells are associated with vigorous delayed-type hypersensitivity reactions.
