Endothelin and PDGF do not stimulate peripheral blood monocyte chemotaxis, adhesion to endothelium, and superoxide production
Abstract
Endothelin is a potent vasoconstrictory endothelial-derived peptide which can induce smooth muscle proliferation and therefore may be proatherogenic. Platelet-derived growth factor is also a potent mitogenic vasoconstrictory protein which is proatherogenic. We report that neither endothelin nor PDGF stimulate superoxide production, or monocyte adhesion to porcine aortic endothelial cell monolayers; additionally endothelin is not a chemoattractant factor for monocytes. If endothelin and PDGF are important in atherogenesis it is unlikely that a monocyte response to these mediators is involved.
