Detouring adrenergic stimulation to induce adipose thermogenesis

Harnessing the thermogenic, energy-expending capacity of adipocytes has the potential to combat metabolic disorders. Although β 3 -adrenergic receptor agonists are the best-known activators of thermogenesis, they carry considerable cardiovascular risks. A new study demonstrates the ability of G protein-coupled receptor 3 to intrinsically drive adipose thermogenesis independent of β 3 -adrenergic receptor signalling.
