Abstract (original English)
Objectives Brown adipose tissue (BAT) dissipates energy via non-shivering thermogenesis, but durable thermogenic benefit requires sustained cold remodeling that stabilizes a cold-adapted tissue state. While most studies have focused on adipocyte-intrinsic pathways that drive acute activation, how stromal niche cells-particularly the vasculature-sense and coordinate long-term adaptation remains poorly defined. Because GPCRs are key sensors of extracellular and neurohumoral cues, we mapped GPCR expression across mouse and human BAT at single-nucleus resolution and identified adhesion GPCRs as a prominent family enriched in vascular cells, with endothelial ADGRF5(GPR116) emerging as a leading candidate regulator. Methods Single-nucleus RNA sequencing of mouse and human BAT was used to map GPCR expression across cell types. Global, inducible endothelial-specific, and adipocyte-specific ADGRF5(GPR116) knockout mouse models were each challenged with acute and prolonged cold exposure. Endothelial and adipocyte states were analyzed using single-nucleus RNA sequencing transcriptional profiling, functional vascular assays, and cell-cell communication modeling. Results Endothelial deletion of ADGRF5(GPR116) impaired the ability of mice to sustain thermogenesis during prolonged cold exposure, whereas adipocyte-specific deletion did not affect thermogenic capacity in vivo.
