Vasoactive intestinal peptide increases VEGF expression to promote proliferation of brain vascular endothelial cells via the cAMP/PKA pathway after ischemic insult in vitro.

abstract：:The location of the cells giving rise to the tachykinergic innervation of the rat arcuate nucleus was studied by combining immunohistochemistry and retrograde axonal transport of a protein-gold complex (WGA-ApoHRP-gold). Small volumes (20 nl) of this marker were injected into the arcuate nucleus of the rat. Twenty-fou...
