Macrophage-activating lipopeptide 2 (MALP-2) is an agonist of Toll like receptors TLR-2/TLR-6. Macrophage-activating lipopeptide-2 can enhance endothelial nitric oxide synthase ( eNOS ) phosphorylation and endothelial cell release of NO, thereby improving vasodilation. Macrophage-activating lipopeptide-2 can enhance endothelial adhesion of white blood cells and improve perfusion recovery and collateral growth in the hind limbs of hypercholesterolemic Apoe deficient mice undergoing experimental femoral artery ligation (FAL).
