Description_x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ Cholecystokinin is expressed in the gastrointestinal tract and the central nervous system. Cholecystokinin receptor type 2 (CCK2) is a GPCR that is highly expressed in brain and spinal cord. CCK2 is implicated in many brain processes, including mood, anxiety, and pain, through its modulation of GABA neurotransmission._x000D_ LY225910 is a potent, selective CCK2 antagonist. LY225910 blocks agonism of CCK2 by CCK-8S, the peptide agonist. LY225910 has been measured in multiple systems, including GABA efflux from cortical cultures, depolarization of spinal cord neurons (via potassium conductance), modulation of excitatory postsynaptic potentials (EPSPs) in nucleus accumbens slices, and enhancement of morphine analgesia._x000D_ Features and Benefits_x000D_ This compound is featured on the Cholecystokinin and Gastrin Receptors page of the Handbook of Receptor Classification and Signal Transduction.
