Memory/effector (CD45RBlo) CD4 T cells are controlled directly by IL-10 and cause IL-22–dependent intestinal pathology


The role of direct IL-10 signaling in different T cell subsets is not well understood. To address this, we generated transgenic mice expressing a dominant-negative IL-10 receptor specifically in T cells (CD4dnIL-10Rα). We found that Foxp3-depleted CD45RB(lo) (regulatory T cell [T(reg) cell]-depleted CD45RB(lo)) but not CD45RB(hi) CD4(+) T cells are… (More)
