tlqp 21

TLQP 21 acetate is a potent agonist of G-protein-coupled receptor complement-3a receptor 1 (C3aR1). The EC50 values are 10.3 μM for mouse and 68.8 μM for human. TLQP 21 acetate is a VGF-derived peptide with endocrine and extraendocrine properties.

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.

TLQP-21 TFA, a VGF-derived peptide with endocrine and extraendocrine properties, acts as a potent G-protein-coupled receptor complement-3a receptor1 (C3aR1) agonist (EC50: mouse TLQP-21=10.3 μM; human TLQP-21=68.8 μM), activating C3aR1 to increase intracellular Ca2+ levels, and is used in research on nociception regulation and other relevant physiological functions[1][2].

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
