Description | PACAP-38 (human, mouse, ovine, porcine, rat) also called Pituitary Adenylate Cyclase Activating Polypeptide-38 (human, mouse, ovine, porcine, rat), PACAP (1-38), human, ovine, rat. Kojro et al. observed that the PAC1 agonists PACAP-27 and PACAP-38 strongly increased the activity of α-secretase. Upregulation of this APP-degrading enzyme promotes the non-amyloidogenic processing of APP, i.e. reduces the production of Aβ40/42, and thus may help to prevent Alzheimer’s disease. Nasally applied PACAP-38 in APP[V717I]-transgenic mice additionally enhanced the production of the Aβ-degrading enzyme neprilysin via induction of somatostatin. |
