title: CGRP stimulates the adhesion of leukocytes to vascular endothelial cells.
abstract: Calcitonin gene-related peptide (CGRP) stimulates the adhesiveness of human umbilical vein endothelial cells for U937 cells and human neutrophils in a dose- and time-dependent manner. The onset of CGRP-induced adhesives of HUVEC was rapid (30 min), independent of protein synthesis, and lasted over 24 h in the continuous presence of the peptide. The stimulatory effect of CGRP was completely blocked by the CGRP antagonist, CGRP(8-37). The present study provides evidence in support of the potential role of sensory nerve-derived neuropeptides in the modulation of leukocyte adhesion to vascular endothelial cells.
