Human galanin is a 30-amino acid neuropeptide and galanin (GAL) receptor agonist.1,2,3,4It inhibits forskolin-induced cAMP production in HEK293E cells expressing recombinant human GAL1receptors (EC50= 0.031 nM) and stimulates inositol phosphate accumulation in CHO cells expressing recombinant human GAL2receptors (EC50= 12.3 nM).1,2Human galanin induces contractions in isolated rat longitudinal fundus strips with an EC50value of 13.8 nM.3Intrathecal administration of human galanin (3, 10, and 30 nmol/animal) reduces paw licking and flinching in the second, but not first, phase of the formalin test in rats.4
