Chemotaxis and chemokinesis
WebChemotaxis and chemokinesis were markedly impaired, but staphylococcal killing was normal and neutrophil oxidative burst was increased both basally and upon stimulation. Neutrophil spreading on glass and cell polarization were also impaired. Neutrophil F-actin was elevated 4-fold, suggesting an abnormality in F-actin regulation. WebAug 28, 2003 · Both neutrophil chemotaxis and chemokinesis elicited by granulocyte-macrophage colony-stimulating factor (GM-CSF) were strongly inhibited by rapamycin with an IC(50) of 0.3 nM. Inhibition, although at a higher dose, was also observed when the chemoattractant was interleukin-8. As for the mechanism, rapamycin targeted the …

WebFeb 1, 2010 · Here we describe a novel chemotaxis assay based upon the invasion of cells into agarose spots into which chemoattractants are suspended. Our studies demonstrate that this system assays chemotaxis and not chemokinesis, and provide proof-of-principle for drug screening studies as well as analysis through high-resolution cellular imaging. WebChemotaxis assays enable the investigation of: Chemotactic behavior of cells after knockout, knockdown, or overexpression of the gene of interest. Chemotactic potential of substances. Effect of chemotaxis inhibitors and enhancers. Differentiation between chemotaxis and chemokinesis (enhanced migration)
WebThe CCL2-CCR2 AC-cancer cell axis drives cancer cell chemotaxis and chemokinesis at the BBB. Given its important role on TC transmigration, we next investigated the mechanism of action of AC-derived CCL2. First, we verified that the secreted chemokine could reach the intravascular TC. Immunofluorescence staining of triculture MVNs for CCL2 with ...
