Identification of novel agonists of the integrin CD11b/CD18.
We report the identification of novel small molecule agonists of integrin CD11b/CD18, which increased, in a dose-dependent manner, the adhesion of the integrin CD11b/CD18 expressing cells to two physiologically relevant ligands: Fibrinogen and iC3b. Compound 6 showed an ex vivo EC(50) of 10.5 microM and in vitro selectivity for binding to the recombinant alphaA-domain of CD11b/CD18. In silico d...
متن کاملNeutrophil activation and priming during engagement of CD11b/CD18 integrins.
An early first stage of the inflammatory response is neutrophil extravasation, during which neutrophils adhere to endothelial cells lining blood vessels, change shape, and become motile. The neutrophils subsequently migrate through the endothelial layer and chemotax towards the site of inflammation [ I ] . One of the important neutrophil integrins involved in this process is CDI lb/18 (Mac-I) [...
متن کاملMyeloperoxidase mediates neutrophil activation by association with CD11b/CD18 integrins.
Recruitment and activation of polymorphonuclear neutrophils (PMNs) reflects a primary immunological response to invading pathogens and has also emerged as a hallmark of vascular inflammation. One of the principal enzymes released upon PMN activation is myeloperoxidase (MPO), a heme protein that not only generates cytotoxic oxidants but also impacts deleteriously on nitric oxide-dependent signal...
متن کاملContinuous activation and deactivation of integrin CD11b/CD18 during de novo expression enables rolling neutrophils to immobilize on platelets.
In an in vitro flow model, unstimulated neutrophils rolled steadily over a surface coated with platelets, until superfusion of the chemotactic peptide formyl-methionyl-leucyl-phenylalanine (fMLP) caused a dose-dependent (10(-11) to 10(-7) mol/L) transition from rolling to stationary attachment in seconds, followed more slowly by neutrophil shape change and spreading on the surface, However, at ...
متن کاملPhospholipase D-derived phosphatidic acid is involved in the activation of the CD11b/CD18 integrin in human eosinophils.
Priming of human eosinophils is an essential event for the respiratory burst induced by serum-opsonized particles [serum-treated zymosan (STZ)]. In this study we have found that treatment of eosinophils with platelet-activating factor (PAF) leads to activation of phospholipase D. Inhibition of the formation of phospholipase D-derived products by ethanol resulted in about 90% inhibition of PAF-i...
