Detailed explanation-1: -In previous studies researchers identified a special group of T cells, called suppressor T cells, which can shut down the normal function of other important immune system cells called monocytes and dendritic cells.
Detailed explanation-2: -A type of immune cell that blocks the actions of some other types of lymphocytes, to keep the immune system from becoming over-active. Suppressor T cells are being studied in the treatment of cancer.
Detailed explanation-3: -Regulatory T cells (Treg cells) also have CD4 on their surface, but they do not activate the immune system like helper T cells do. Instead, regulatory T cells play a protective role by shutting off the immune response when it is no longer needed.
Detailed explanation-4: -Tr1 cells have many suppressive mechanisms, including secretion of the suppressive cytokines IL-10 and TGF-, as well as the surface molecules CTLA-426 and programmed death 1 (PD-1).
