WebApr 7, 2024 · The high-affinity conformation of LFA-1 interacts with its endothelial ligand ICAM-1, which stops slow rolling and arrests the neutrophil on the endothelial surface. 39 In addition to the β 2-integrin LFA-1, the β 1-integrins very late antigen 6 (VLA-6; binding to laminins) and VLA-4 (binding to VCAM-1) have been implicated in neutrophil ... The phases of the leukocyte extravasation depicted in the schema are: approach, capture, rolling, activation, binding, strengthening of the binding and spreading, intravascular creeping, paracellular migration or transcellular migration. Selectins are expressed shortly after cytokine activation of endothelial cells by tissue macrophages. Activated endothelial cells initially express P-selectin molecules, but within two h…
