Definition of T-suppressor cell

T-suppressor cell: A type of immune cells, also called CD8 cells, these cells close down the immune response after it has destroyed invading organisms. CD8 cells are sensitive to high concentrations of circulating lymphokine hormones and release their own lymphokines after an immune response has achieved its goal, signaling all other participants to cease their attack. Some memory B-cells remain to ward off a repeat attack by the invading organism.
