Gpr174 is a regulator of regulatory T cells, which play an important role in angiogenesis after hindlimb ischemia. Here, the authors show GPR174-deficient Tregs promote AREG expression by inhibiting Gαs/cAMP/PKA signal pathway and increasing EGR1 nuclear accumulation to improve angiogenesis and vascular remodeling in response to ischemic injury.
