title: Effect of synthetic PAF-acether on human neutrophil function.
abstract: Synthetic PAF-acether was studied for its effect on human neutrophil migration and secretion. Based on checkerboard analysis, the factor is chemokinetic for neutrophils, but it also enhances ECF-stimulated chemotaxis. By itself, PAF-acether does not induce ECF or beta-glucuronidase secretion from neutrophils, but it causes a dose-dependent enhancement of release in the presence of zymosan. PAF-acether thus potentially modulates neutrophil functions during inflammatory events.
