Varying roles of E-selectin and P-selectin in different microvascular beds in response to antigen.
Expression of E-selectin and P-selectin is critical in the effector phase of leukocyte recruitment in response to Ag. Whether their relative roles differ between tissues in response to the same Ag is unknown. In this study, a type I hypersensitivity response was elicited in C57BL/6 mice by systemic sensitization with OVA. Following local Ag challenge, endothelial selectin expression was examine...
متن کاملOverlapping roles for L-selectin and P-selectin in antigen-induced immune responses in the microvasculature.
Although L-selectin mediates lymphocyte attachment to endothelial venules of peripheral lymph nodes, its role in leukocyte recruitment into tissues following Ag challenge is less well established. The objective of this study was to systematically examine the role of L-selectin in leukocyte rolling in the peripheral microvasculature during the first 24 h of an immune response. A type I hypersens...
متن کاملP - Selectin , L - Selectin , and a 4 lntegrin Have Distinct Roles in Eosinophil Tethering and Arrest on Vascular Endothelial Cells
The adhesive interactions of eosinophils with purified E-, P-, and L-selectins; vascular cell adhesion molecule-1 molecule; and HUVEC were examined in shear flow. Compared with neutrophils, eosinophils showed markedly less binding to E-selectin, but significantly stronger avidity for P-selectin. Both cell types showed a similar level of tethering and rolling on L-selectin. Eosinophils tethered ...
متن کاملCerebral microvascular responses to hypercholesterolemia: roles of NADPH oxidase and P-selectin.
Although hypercholesterolemia is widely accepted as a major risk factor for coronary artery and peripheral vascular diseases, its role in the pathogenesis of stroke is controversial. The objectives of this study were to determine how hypercholesterolemia affects the cerebral microcirculation under resting conditions and after ischemia-reperfusion (I/R). Platelet- and leukocyte-endothelial cell ...
متن کاملNeutrophil-platelet adhesion: relative roles of platelet P-selectin and neutrophil beta2 (DC18) integrins.
Neutrophils and platelets interact both physically and metabolically during inflammation and thrombosis, but the mechanisms responsible for their adhesion remain incompletely understood. Neutrophil-platelet adhesion was measured after specific stimulation of neutrophils, platelets, or both and quantified by flow cytometry. Specific stimulation of either the neutrophil or the platelet led to a m...
