Peptidergic and non-peptidergic innervation and vasomotor responses of human lenticulostriate and posterior cerebral arteries
(2004) In Peptides 25(12). p.2105-2114- Abstract
- The aim of the present study was to compare in man the innervation pattern and the functional responses to neuronal messengers in medium sized lenticulostriate and branches of the posterior cerebral arteries (PCA). The majority of the nerve fibers found were sympathetic and displayed specific immunoreactivity for tyrosine hydroxylase (TH) and neuropeptide Y (NPY). Only few nerve fibers displayed vasoactive intestinal polypeptide (VIP), calcitonin gene-related peptide (CGRP) and substance P (SP) immunoreactivity. In both arteries. the contractions induced by noradrenaline (NA), NPY and 5-hydroxytryptarnine (5-HT) and the relaxant responses induced by acetylcholine (ACh). VIP and pituitary adenylate cyclase activating peptide-27 (PACAP) as... (More)

VIP and pituitary adenylate cyclase activating peptide-27 (PACAP) as well as CGRP and SP were compared in vitro. In conclusion. there was no major difference in innervation pattern or vasomotor sensitivity (pEC(50) and pIC(50) values) between the two vessels'. However. the general pattern indicates stronger vasomotor responses (E-max and I-max) in the PCA branches as compared to the lenticulostriate arteries which may lend support for the clinical observation of a difference in stroke expression between the two vascular areas.
