WebBriefly, neutrophils were mixed with ferricytochrome c or the elastase substrate at 37 °C, and then treated with testing drugs for 5 min. FMLP (30 nM) or MMK-1 (100 nM) in the pretreatment of cytochalasin B as well as PMA (5 nM) were added to activate neutrophils. The change in absorbance was monitored continuously at 550 and 405 nm ... WebSuspended in media containing calcium and magnesium, human neutrophils aggregate briefly when exposed to arachidonic acid. The magnitude and duration of this response was enhanced by the presence of increased magnesium concentration, increased magnesium plus calcium concentrations, and cytochalasin B.

WebJan 18, 2024 · The time-course (A), activation ratio (B), peak intensity (C) and delay time (D) of P-selectin-induced calcium signaling of neutrophils, treated with or without cytochalasin B (cytoskeleton actin depolymerization agent) and MβCD (membrane lipid rafts disruption), at a wall shear stress of 0.2 Pa.
WebAim 1. Uncover specific mechanical or biochemical cues that are necessary and/or sufficient to induce calcium bursts. Before micropipette experiments, human neutrophils will be treated with an actomyosin inhibitor (e.g. latrunculin A, cytochalasin D, blebbistatin) or a β 2-integrin (LFA-1 or Mac-1) blocking antibody. Our analysis of the calcium response will …
