Bistable Regulation of Adipocyte Heterogeneity Controls Thermogenesis

This study reveals that brown adipocytes exist in two states distinguished by UCP1 expression, with IL-1β from immune cells stabilizing the low-UCP1 state. The mechanism involves IL-1β preventing degradation of H6PD, promoting glucocorticoid activation and suppression of thermogenic gene expression. These findings provide insight into how immune signaling influences adipocyte function and energy homeostasis.
