T-8 cells

T cells that express the CD8 transmembrane glycoprotein (CD8+ T cells).

They close down the immune response after invading organisms are destroyed.

Suppressor T cells are sensitive to high concentrations of circulating lymphokine hormones, and release their own lymphokines after an immune response has achieved its goal.

This signals all other immune-system participants to cease their attack.

Some memory B-cells remain after this signal to ward off a repeat attack by the invading organism.

Also known as T-suppressor cells.
