Abstract:
Modulation of the T-cell response depends chiefly on regulatory T cells (Treg), which express CD4 and CD25. Some Treg cells are present naturally, whereas others are induced in response to antigens. The immunomodulating effects of Treg cells are mediated by membrane molecules (e.g., CTLA4, GITR, and OX40) and cytokines. IL-35 seems to be a crucial mediator, although IL-10 and TGFbeta are also important. The role for Treg cells in rheumatoid arthritis (RA) has been established in both patients and animal models. Treg function is deficient in RA, whereas Treg counts vary. Treg counts increase in patients who are responding to TNFalpha antagonist therapy. Among current hypotheses, Treg expansion or transfer may hold promise for the treatment of RA.
