OBJECTIVE: Neutrophils are involved in the inflammatory responses during
atherosclerosis. Human neutrophil peptides (HNPs) released from activated
neutrophils exert immune modulating properties. We hypothesized that HNPs play an
important role in neutrophil-mediated inflammatory cardiovascular responses in
atherosclerosis. METHODS AND RESULTS: We examined the role of HNPs in
endothelial-leukocyte interaction, platelet activation, and foam cell formation
in vitro and in vivo. We demonstrated that stimulation of human coronary artery
endothelial cells with clinically relevant concentrations of HNPs resulted in
monocyte adhesion and transmigration; induction of oxidative stress in human
macrophages, which accelerates foam cell formation; and activation and
aggregation of human platelets. The administration of superoxide dismutase or
anti-CD36 antibody reduced foam cell formation and cholesterol efflux. Mice
deficient in double genes of low-density lipoprotein receptor and low-density
lipoprotein receptor-related protein (LRP), and mice deficient in a single gene
of LRP8, the only LRP phenotype expressed in platelets, showed reduced leukocyte
rolling and decreased platelet aggregation and thrombus formation in response to
HNP stimulation. CONCLUSIONS: HNPs exert proatherosclerotic properties that
appear to be mediated through LRP8 signaling pathways, suggesting an important
role for HNPs in the development of inflammatory cardiovascular diseases.
