PACAP (1-38), human, ovine, rat is a neuropeptide with 38 amino acid residues. PACAP (1-38) binds to PACAP type I receptor, PACAP type II receptor VIP1, and PACAP type II receptor VIP2 with IC50s of 4 nM, 2 nM, and 1 nM, respectively.
PACAP (1-38), human, ovine, rat is a fragment of pituitary adenylate cyclase activating polypeptide[1]. PACAP (1-38) shows high affinity for PACAP specific (PAC1) receptor in membranes from various tissues including the endocrine pancreas[2]. In vitro, PACAP (1-38) relaxes guinea-pig and rabbit tracheal smooth muscle precontracted by histamine and by acetylcholine. PACAP (1-38) also increases adenosine 3':5'-cyclic monophosphate (cyclic AMP) in tracheal smooth muscle, providing a possible mechanism for the relaxant effect of PACAP (1-38)[3].
PACAP (1-38) alone in sham animals does not result in changes in any of the retinal layers. PACAP (1-38) dissolved in solutio ophthalmica cum benzalkonio leads to significant protection in the retina in bilateral common carotid artery occlusion (BCCAO)-lesioned retinas
retinas treated with PACAP (1-38) eye drops have preserved structure compared to control retinas. OLM-ILM (outer limiting membrane-inner limiting membrane) distance is reduced by 49.7% (p[4].
Rats[4] Wistar rats (n=20:n=12 for histological analysis, n=8 for immunohistochemical analysis) weighing 250-300 are fed and watered ad libitum, under light/dark cycles of 12/12 h. Directly after the operation within 1 min, the right eye is treated with PACAP (1-38) eye drops (1 µg/drop). The vehicle used is benzalkonium-chloride in a concentration of 0.005%, as it is the most effective vehicle to achieve neuroprotection with PACAP1-27 eye drops. The left eye serves as a control, treated only with the vehicle. A group of animals serve as the sham-operated group that undergo anesthesia and all steps of the surgical procedure except ligation of the carotid arteries. Rats are treated twice a day with one drop, for 5 consecutive days[4].
