Cerebellin TFA 

Cerebellin TFA is a neuromodulatory hexadecapeptide that serves as a marker for Purkinje cell maturation. Cerebellin TFA stimulates norepinephrine release via the adenylate cyclase/PKA-dependent signaling pathway. Cerebellin TFA reduces insulin secretion from pancreatic islets under high-glucose conditions. Cerebellin TFA also regulates synaptic structure formation and controls catecholamine secretion in peripheral tissues. Cerebellin TFA can be used in neurological research^[1][2][3][4].

Cerebellin (1-100 nM; 10-30 min) TFA potently stimulates the production of norepinephrine and cyclic adenosine monophosphate in rat adrenal medullary tissues via an adenylate cyclase/PKA-dependent pathway^[1].
Cerebellin (1-100 nM; 90 min) TFA inhibits glucose-stimulated insulin secretion from isolated rat islets^[2].
Cerebellin (100 nM-1 μM; 1 hour) TFA inhibits glucose/Exendin-4 (HY-13443)-stimulated insulin secretion in INS-1 cells^[2].
Cerebellin (10 nM-1 μM; 5 min) TFA reduces Forskolin (HY-15371)-induced cAMP accumulation in INS-1 cells in a concentration-dependent manner^[2].
Cerebellin (100 nM) TFA irreversibly reduces the intracellular free calcium concentration in INS-1 cells^[2].

Cerebellin (1-1000 nM; intrarenal adrenal perfusion; continuous administration during sample collection) TFA potently stimulates norepinephrine release from perfused rat adrenal glands via an adenylate cyclase/PKA-dependent pathway^[1].
Cerebellin (0.5-1.5 nmol/100 g body weight; subcutaneous injection; single bolus) TFA acts as an insulin inhibitor in healthy female Wistar rats^[2].
