Brown adipose tissue activation

Brown adipose tissue activation refers to the stimulation of specialized fat cell-rich tissue (brown adipose tissue) that is capable of dissipating energy as heat via non-shivering thermogenesis, primarily mediated by the action of the mitochondrial protein uncoupling protein 1 (UCP1). Activation typically occurs through sympathetic nervous stimulation, primarily via β-adrenergic receptors in response to cold, certain drugs (such as β3-adrenergic agonists, e.g., mirabegron), food bioactives (capsaicin/capsinoids), or hormonal triggers (secretin, bile acids). Induced BAT activation leads to glucose and lipid clearance, increased energy expenditure, and improved metabolic profiles, representing a therapeutic interest for obesity, metabolic syndrome, and related conditions. Brown adipose tissue as a research and therapeutic focus encompasses multiple molecular targets—including β-adrenergic receptors, UCP1, PRDM16, TGR5, and signaling pathways such as AMPK—but \"brown adipose tissue activation\" itself is not a singular molecular target. For structured drug target annotation, each responsible molecule (e.g., β3-adrenergic receptor, UCP1) should be considered separately.

Brown adipose tissue activation occurs through various pathways including β-adrenergic receptor agonism (mainly β3 in rodents, β1/β2/β3 in humans), TRP channel agonism (e.g., with food ingredients such as capsaicin), gut hormone/receptor signaling (such as secretin via the secretin receptor), bile acid activation of TGR5, PRDM16-mediated browning and gene activation, and AMPK activation.
