Secretory vesicles of human neutrophils European

The emigration is a sequential process that includes three steps (Smith et al 1991 von Andrian et al 1991 Springer 1995) 1) A selectin-mediated reversible tethering that brings the neutrophil to roll along the endothelial wall 2) Stimulation of the neutrophil by chemoattractants resulting in upregulation of membrane proteins on the neutrophil surface and 3) Firm adhesion mediated by

Isoflurane inhibits neutrophil recruitment in the

Neutrophil recruitment to the inflammatory sites is regulated by a variety of adhesion molecules including β2 integrins The dependency of neutrophil recruitment on β2 integrins is variable in different tissues but has not yet been verified in the cutaneous passive reverse Arthus reaction We examined this question and also evaluated the impact of isoflurane on neutrophil recruitment to the

Molecular events during leukocyte diapedesis

Dangerfield et al showed that homophilic neutrophil–endothelial PECAM‐1 binding is important for neutrophil passage through the perivascular basement membrane in vivo [] and that these interactions result in an up‐regulation of α 6 β 1 integrin (the leukocyte receptor for laminin) mediating leukocyte migration through the perivascular basement membrane [] To date most studies

While the contribution of intracellular adaptor proteins to lymphocyte activation has been well studied the function of these molecules in innate immune effector cells such as neutrophils has not been extensively addressed Here we demonstrate a critical role for the adaptor molecule SH2 domain-containing leukoctye-specific phosphoprotein of 76 kDa (SLP-76) in FcγR and integrin signaling

Frontiers

While integrins can utilize both clathrin-dependent and -independent pathways LFA-1-dependent endocytosis is primarily mediated through clathrin-independent cholesterol-sensitive mechanisms and play an important role both in mediating cell migration and cell polarization through the partitioning of molecules near LFA-1 (68–70) Upon internalization a series of steps determine the fate of

Neutrophil rolling is a prerequisite for the transition to a shear-resistant firm adhesion on the endothelium (2-4 7) Neutrophil arrest is mediated by the β 2-integrins whose expression level and avidity for ligands are increased by the binding of chemotactic receptors early in the process of emigration

Additionally LFA-1-mediated adhesion of mouse thymocytes (Krauss and Altevogt 1999) and human T-cell adhesion through LFA-1 and α4β1 (Leitinger and Hogg 2002) is abolished when lipid rafts are disrupted by the extraction of cholesterol with methyl-β-cyclodextrin These data suggest that activation of integrins results in their localization to a lipid raft compartment and that this

Neutrophil Function: From Mechanisms to Disease

Stimulation of the neutrophil by a chemoattractant often results in endocytosis of the corresponding receptor thus leading to a desensitization of the neutrophil to repeated stimulation with the same molecule (30 31) The rich and varied input received by a neutrophil during this final leg of the activation process is complex and the exact effects of priming desensitization and signaling
