Our previous studies in the rabbit trigeminal nerve (TgN) showed that pituitary adenylate cyclase-activating peptide (PACAP) accelerated the extension of neuronal processes and recovery of corneal sensitivity. The purposes of the present study were 1) develop a procedure to culture...

Background Many patients with migraines suffer from allergies and vice versa, suggesting a relationship between biological mechanisms of allergy and migraine. It was proposed many years ago that mast cells may be involved in the pathophysiology of migraines. We set...

Pituitary adenylate cyclase-activating polypeptide (PACAP) increases cAMP production and stimulates hormone release from a variety of anterior pituitary cells. However, in anterior pituitary gonadotrophs PACAP stimulates oscillations in cytosolic free Ca2+ concentration ([Ca2+]i) that appear to be independent of cAMP....

The present study was aimed at investigating whether PACAP stimulates accumulation of cAMP, as well as hormonal secretion of homogeneous populations of pituitary proopiomelanocortin (POMC) cells, namely melanotrophs and AtT-20 corticotrophs. PACAP was shown to enhance cAMP accumulation in a...
