pubmed:abstractText
Pituitary adenylate cyclase-activating peptide (PACAP) is a neuropeptide with strong bronchodilator capacity, present in the human airways. There is recent evidence that PACAP decreases the release of proinflammatory cytokines. We have previously shown that PACAP inhibits neutrophil chemotaxis, but altogether little is known about the effects of PACAP on granulocytes. The present study was designed to investigate if PACAP and the closely related peptide vasoactive intestinal peptide (VIP) could affect the cell surface expression of CD11b, CD63 and CD66b in human neutrophils. Neutrophils isolated from 12 healthy blood donors were incubated with either PACAP or VIP, and the expression of neutrophil cell surface markers was assessed using flowcytometry. Neutrophils incubated with PACAP38 exhibited a marked, concentration-dependent increase in their expression of CD11b, CD63 and CD66b. In contrast, neutrophils incubated with VIP showed no increase of the investigated surface markers. This indicates a role for PACAP in granulocyte activation, mediated via a pathway not shared with VIP. Together with the previously presented data on leukocyte migration it suggests that PACAP acts as a regulator of neutrophil inflammation.
