| abstractText | Perivascular adipocyte progenitor cells (APCs) can generate cold temperature-induced thermogenic beige adipocytes within white adipose tissue (WAT), an effect that could counteract excess fat mass and metabolic pathologies. Yet, the ability to generate beige adipocytes declines with age, creating a key challenge for their therapeutic potential. Here we show that ageing beige APCs overexpress platelet derived growth factor receptor beta (Pdgfrbeta) to prevent beige adipogenesis. We show that genetically deleting Pdgfrbeta, in adult male mice, restores beige adipocyte generation whereas activating Pdgfrbeta in juvenile mice blocks beige fat formation. Mechanistically, we find that Stat1 phosphorylation mediates Pdgfrbeta beige APC signaling to suppress IL-33 induction, which dampens immunological genes such as IL-13 and IL-5. Moreover, pharmacologically targeting Pdgfrbeta signaling restores beige adipocyte development by rejuvenating the immunological niche. Thus, targeting Pdgfrbeta signaling could be a strategy to restore WAT immune cell function to stimulate beige fat in adult mammals. |
