WebMay 19, 2024 · A chemokinesis assay was developed that measures the speed of cells before and after uniform stimulation with folic acid. This assay was used to measure the response of wild-type Ax2 cells, cells treated with chemical inhibitors, and genetic knockout mutants lacking critical components of the cAMP chemotactic signaling pathways. WebChemotaxis and chemokinesis were markedly impaired, but staphylococcal killing was normal, and neutrophil oxidative burst was increased both basally and on stimulation. Neutrophil spreading on glass and cell polarization were also impaired. Neutrophil F-actin was elevated fourfold, suggesting an abnormality in F-actin regulation.

WebIn particular, the invention provides methodology for promoting CD4+ cell chemotaxis to a localized site of infection as a means of augmenting the efficacy of extant chemotherapeutic methods. The invention further provides methodology for diverting CD4+ cell infiltration from a localized site where the presence of CD4+ cells is detrimental to ...

WebChemotaxis is described as the directed migration of cells towards a chemoattractant. This process is different from chemokinesis, which is undirected cell migration. When cells undergo chemokinesis, they alter …

WebChemokines promote the directional migration of cells expressing CKRs, which can be measured in chemotaxis assays using a Boyden chamber. Cells are placed in the upper chamber, which is separated with a porous membrane from the lower chamber containing the chemoattractant (e.g., chemokines) and cells migrate toward the lower chamber. … gulf coast rhythmicsWebOver-expression of PTEN inhibited EGF-induced chemotaxis, probably due to an overall reduction of PIP3 levels. Disruption of PTEN by siRNA caused a marked decrease in chemokinesis, cell adhesion, and membrane spreading, resulting in a severe defect in chemotaxis.
