All-<i>trans</i>Retinoic Acid Inhibits Type 1 Diabetes by T Regulatory (Treg)-Dependent Suppression of Interferon-γ–Producing T-cells Without Affecting Th17 Cells

Abstract

These results demonstrate that ATRA treatment promoted in vivo expansion of Treg cells and induced Treg cell-dependent immune tolerance by suppressing IFN-gamma-producing T-cells, without affecting Th17 cells. Our study also provides novel insights into how ATRA induces immune tolerance in vivo via its effects on Teff and Treg cells.
