Ma et al. reported that DDX5 is a negative regulator of the retinoic acid-receptor (RAR)-related orphan receptor γ t (RORγt)-expressing regulatory T cells (RORγt + Tregs) suppressor activities [68], and that loss of DDX5 unleashes IL-10 production potential and suppressor activity in RORγt + Treg and protects against weight loss and pathology in murine models of T cell–mediated intestinal inflammation (Fig. 3D1) [68]. This evidence concerns the gene DDX5 and inflammation.
