MOBILIZING BROWN FAT THERMOGENESIS
- Endogenously occuring natural peptide
- Non-adrenergic activator
- Increasing negative energy
Brown adipose tissue (BAT) harbors a remarkable capacity to evoke energy expenditure through its uncoupling protein 1 (UCP1) dependent thermogenic function. Upon activation, Ucp1 dissipates food energy as heat by uncoupling mitochondrial respiration from ATP synthesis. Therefore, BAT provides a potential therapeutic target against obesity and diabetes. As sympathomimetic drugs exhibit detrimental cardiovascular effects, their application as BAT-stimulating agents is considered problematic.
The endogenously occurring natural peptide secretin is a non-adrenergic activator of BAT. Treatment of primary brown adipocytes with unmodified recombinant secretin stimulates UCP1-mediated thermogenesis to a similar extent as an established adrenergic agonist (see Figure A, B). Moreover, secretin exerts an inhibitory effect on food intake (see Figure C,D).
