GMP-140 (P-selectin) inhibits human neutrophil activation by lipopolysaccharide: analysis by proton magnetic resonance spectroscopy.
Proton magnetic resonance spectroscopy has been used to monitor the effect of GMP-140 on the stimulation of human peripheral blood neutrophils. Stimulation of neutrophils by lipopolysaccharide gives rise to a high resolution lipid spectrum from the intact cells. Fluid phase GMP-140, which prevents adhesion and development of inflammatory responses of neutrophils, was found to inhibit these changes in the lipid spectrum by up to 40%. Anti-GMP-140 Fab fragments reversed this effect while non-immune Fab fragments did not affect the observed inhibition by GMP-140.
