Summary
This research article investigates the link between heat stress and metabolic dysfunction. Using mouse models, the study reveals that exposure to heat stress increases susceptibility to diet-induced metabolic disorders. The mechanism involves a skin-hypothalamus axis where elevated skin-derived KLK14 (kallikrein-related peptidase 14) epigenetically reprograms hypothalamic LRRC7+ astrocytes, which in turn suppress neighboring paraventricular nucleus (PVN) OXT neurons. The study also demonstrates that Vitamin A can reduce KLK14 levels and mitigate metabolic impairment in both mice and humans, suggesting a potential therapeutic approach for heat-stress-related metabolic conditions.
