Abstract

The functional significance of E-selectin binding to neutrophils under shear flow in the absence of chemotactic stimulation is examined. Two experimental settings were used. One simulates the potential influence of hydrodynamic shear on intercellular adhesive interactions in a parallel plate flow chamber, and the other employs flow cytometry to examine the specificity in ligand binding and neutrophil activation in suspension. Evidence suggests the activation of neutrophils rolling on E-selectin that is independent of signaling through G-proteins. Neutrophil emigration appears to be regulated by shear and signals transduced through selectins during tethering and rolling.
