P-selectin- and CD18-mediated recruitment of canine neutrophils under conditions of shear stress

Abstract

Neutrophil mobilization at sites of inflammation or thrombosis involves the participation of several adhesion molecules expressed on neutrophils and vascular endothelial cells. Local vascular damage with disruption of the endothelium results in adhesion of platelets to the exposed subendothelium, and these platelets could also participate in neutrophil recruitment. This initial phase of mobilization could be followed by heterotypic aggregation to recruit more leukocytes in the area. The present study first examined the interactions of adherent canine platelets and flowing canine neutrophils using an in vitro system that simulates vascular flow conditions. Results showed that collagen-adherent platelets express the adhesion molecule P-selectin on their surface and can support neutrophil arrest (612 +/- 43 neutrophils/mm2) at shear stresses of approximately 2.5 dynes/cm2. Both transient adhesion (manifested by a rolling-type behavior) and complete arrest were observed. These interactions could be totally inhibited by a monoclonal antibody directed against platelet P-selectin (24 +/- 18 neutrophils/mm2) but not by a monoclonal antibody against neutrophil CD18 (625 +/- 46 neutrophils/mm2). Additionally, under shear mixing condition...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
