Abstract Disruption of endothelial barrier is a crucial factor in the pathogenesis tissue inflammation, hallmark inflammatory diseases such as diabetes and atherosclerosis. Increased permeability occurs because loss cell–cell contacts disruption cell–extracellular matrix (ECM) adhesions. Vascular injury associated with activation coagulation cascade release thrombin, which increases by activati...

We have previously reported the production of endothelin, a potent vasoconstrictor peptide, by porcine cerebral microvessel endothelia and suggested its important role in the regulation of local blood flow within the brain. In our present study, radioimmunoassay with anti-porcine endothelin antiserum revealed that endothelin, produced by cerebral microvessel endothelia grown on a filter, is rel...

Computer-assisted analysis of endothelial morphology provides useful indices of cell shape and size which appear to correlate to the monolayer's functional status. In this study morphometric data obtained by wide-field specular microscopy of in situ corneal endothelia are compared to data obtained by alizarin red S staining of excised corneas. Both human donor corneas and rabbit corneas were st...

Toll-like receptors (TLRs) recognize microbial molecular signatures and can initiate innate immune responses against invading pathogens. A new study (see the related article beginning on page 1234) reports how TLR2 expression by endothelia is locally upregulated by the action of activated polymorphonuclear neutrophils via an unprecedented mechanism involving cell-cell interaction and NAD(P)H ox...

Bacterial dissemination via the cardiovascular system is the most common cause of infection mortality. A key step in dissemination is bacterial interaction with endothelia lining blood vessels, which is physically challenging because of the shear stress generated by blood flow. Association of host cells such as leukocytes and platelets with endothelia under vascular shear stress requires mechan...

Homotypic cell-cell adhesion is essential for tissue and organ development, remodeling, regeneration, and physiological function. Whereas a significant number of homotypic cell-cell adhesion molecules have been identified, much more is known about those concentrated in epithelia than in endothelia. Among the endothelial cell-cell adhesion molecules, very little is known that is specific to endo...
