Activation of A2A adenosine receptors inhibits expression of alpha 4/beta 1 integrin (very late antigen-4) on stimulated human neutrophils.


The alpha 4/beta 1 integrin very late antigen-4 (CD49d/CD29) is up-regulated on circulating neutrophils of septic patients. Although no individual agent mimics this effect of sepsis, we now report that following priming of human neutrophils with lipopolysaccharide or tumor necrosis factor alpha (TNF-alpha), addition of formyl-Met-Leu-Phe (fMLP) results in a… (More)
