Within the immune system, a subtle balance exists between the cells that destroy alien pathogens and those that preserve the body's own tissues. When the balance gets out of whack, the cells that normally target viruses or bacteria can go astray, attacking innocent cells and causing autoimmune and inflammatory disease. Now, researchers at the University of North Carolina at Chapel Hill have revealed the genetic underpinnings of the cells —called Foxp3-expressing regulatory T cells or...

T-regulatory lymphocytes (Tregs) are a subset of T lymphocytes that are involved in the mechanism of immunotolerance to self- and allo-antigens. Activity of these cells is one of the mechanisms of immune evasion of tumors, which inhibits the antitumor activity of effector cells. Tregs are among the tumor-infiltrating lymphocytes and circulate in the peripheral blood. In various cancer types, increased prevalence of Tregs has been observed, and in some studies, this has been reported as a...
