  • Title: Angiogenesis and lipoxins.
    Author: Fierro IM.
    Journal: Prostaglandins Leukot Essent Fatty Acids; 2005; 73(3-4):271-5. PubMed ID: 15982864.
    Abstract:
    Angiogenesis, the growth of new capillaries from pre-existing ones, occurs through dynamic functions of the endothelial cells (EC), including migration, proliferation and maturation, which are essential to achieve an organized formation of the vessel sprout. Aspirin-triggered lipoxins (ATL), the 15R enantiomeric counterparts of native lipoxins, are endogenous lipid mediators generated within the vascular lumen during multicellular responses, which display potent and well-described immunomodulatory actions. Here we present some of the findings regarding the inhibition of EC responses in vitro and in vivo by these novel compounds and the modulation of fundamental steps of the angiogenic process, identifying previously unappreciated vascular actions of locally generated ATL and their longer acting synthetic analogs.
