Abstract Regulatory T cells (Tregs) are potent immune suppressors and critical to the maintenance of immunological tolerance. Interleukin 2 (IL-2) is essential for Treg survival, expansion, phenotypic stability, suppressive function. However, Tregs do not produce IL-2 dependent on exogenous sources IL-2. This poses a significant challenge cell therapies in tissues with no or limited availabilit...
