TLQP 21 is a VGF-derived peptide. TLQP 21 can protect cerebellar granule cells (CGCs) from serum and potassium deprivation-induced apoptosis and increases energy expenditure and prevents early phase diet-induced diabetes.
Chronic intracerebroventricular (ICV) injection of a VGF peptide named TLQP-21 increased resting energy expenditure and temperature in mice. Furthermore, in mice fed a high-fat diet, the same peptide prevented the increase in body and white adipose tissue
