CLAIM CARD
Mechanistically, the findings from Sarmiento-Ortega et al. (2025) implicate direct toxicological pathways in BAT dysfunction, offering a counterpoint to studies focusing on beneficial activators of thermogenesis. The preclinical data suggest that cadmium, a prevalent environmental toxicant, can induce histological damage and functional impairment in BAT at doses previously considered to pose minimal risk. This mechanistic substrate underscores the complexity of BAT regulation, where the organ is responsive not only to cold exposure and sympathetic activation but also to chemical insults. Understanding these adverse pharmacokinetic profiles is critical for a holistic view of BAT health in human populations exposed to environmental pollutants.
