Abstract:
AIMS:Placental growth factor (PlGF), a homologue of vascular endothelial growth factor, is a pleiotropic cytokine with a pro-inflammatory activity. Previous gene-inactivation studies revealed that the loss of PlGF delays atherosclerotic lesion development and inhibits macrophage infiltration, but the activity of an anti-PlGF antibody (alphaPlGF mAb) has not been evaluated yet. METHODS AND RESULTS:We characterized the potential of short-term delivery of alphaPlGF mAb in inhibiting lesion development in ApoE-deficient mice (apoE(-/-)) and in CD4:TGFbetaRII(DN) x apoE(-/-) mice, a more severe atherosclerosis model. Short-term treatment of alphaPlGF mAb reduces early atherosclerotic plaque size and inflammatory cell infiltration in the lesion. CONCLUSION:These pharmacological alphaPlGF mAb results confirm previous genetic evidence that inhibition of PlGF slows down early atherosclerotic lesion development. Furthermore, the phenocopy of genetic and pharmacological loss-of-function strategies underscores that alphaPlGF acts by selectively neutralizing PlGF.
