Regulatory CD4(+)CD25(+) T-cells are controlled by multiple pathways at multiple levels.
CD4(+)CD25(+) regulatory T-cells (Treg cells) are an important subset of T-cells that functions to negatively control immune responses to self or non-self antigens. Depletion of CD4(+)CD25(+) Treg cells leads to the occurrence of lymphoproliferative autoimmune diseases in animals and humans. Therefore, CD4(+)CD25(+) Treg cells must be tightly regulated in the physiologic situation. In this article, we try to summarize the regulating pathways of the development, survival, and function of CD4(+)CD25(+) Treg cells at multiple levels and multiple pathways, including the dendritic cells, costimulatory signals, cytokines, as well as intracellular signals.
