Maintenance of tissue homeostasis is dependent on the communication between stem cells and supporting cells in the same niche. Regulatory T cells (Treg) are a critical component of the stem cell niche to support their differentiation. How Treg cells sense dynamic signals in this microenvironment and communicate with stem cells is mostly unknown. Here, by using hair follicles (HF) to study Treg-stem cell crosstalk, we show that the steroid hormone glucocorticoid instructs skin-resident Treg cells to facilitate HF stem cell (HFSC) activation and HF regeneration. Ablation of the glucocorticoid receptor (GR) in Treg cells blocks hair regeneration without affecting immune homeostasis. Mechanistically, GR and Foxp3 cooperate in Treg cells to induce TGF-β3, which activates Smad2/3 in HFSCs and facilitates HFSC proliferation. This study identifies crosstalk between Treg cells and HFSCs mediated by the GR/TGF-β3 axis, highlighting a possible means to manipulate Treg cells to support tissue regeneration.
