Stem cell-derived tissue-associated regulatory T cells ameliorate the development of autoimmunity.

ABSTRACT: Pluripotent stem cells (PSCs) have the potential to produce almost all of the cells in the body, including regulatory T cells (Tregs). However, the exact conditions required for the development of antigen (Ag)-specific Tregs from PSCs (i.e., PSC-Tregs) are not well delineated. Ag-specific PSC-Tregs can be tissue/organ-associated and migrate to local inflamed tissues/organs to suppress the autoimmune response after adoptive transfer, thereby avoiding potential overall immunosuppression from non-specific Tregs. In this study, we developed a new approach to generate functional Ag-specific Tregs from induced PSCs (iPSCs), i.e., iPSC-Tregs, which had the ability to generate an Ag-specific immunosuppressive response in a murine model of arthritis. We retrovirally transduced murine iPSCs with a c
