摘要
Human recombinant granulocyte-macrophage colony-stimulating factor (GM-CSF) was analysed for effects on the migration of human neutrophilic granulocyte by the Boyden chamber assay. At concentrations ranging from 0.1 to 10 000 U/ml (or 10-12 to 10-7 mol/1) GM-CSF had neither chemokinetic nor chemotactic activity. When added to the cells in the upper compartment of the chamber GM-CSF dose-dependently inhibited the chemotactic migration towards the tripeptide f-Met-Leu-Phe and the complement split product C5a. Chemotaxis towards f-Met-Leu-Phe was inhibited more efficiently by GM-CSF than C5a-induced migration. © 1990.
