Normal adults have very few circulating endothelial cells (CECs) in their blood, but increased levels have been shown in association with conditions associated with endothelial damage such as myocardial infarction and stroke. As atrial fibrillation (AF) is associated with a hypercoagulable state and abnormalities of plasma indices of endothelial damage/dysfunction, we hypothesised that CECs wou...

objective(s): the aim of this study was to estimate effects of hyperbaric (hb) treatment by determination of cd15s and cd11b leukocyte proinflammatory markers expression.  in addition, this study describes changes in cd77 and cd34 expression on rat endothelial cells in renal, pulmonary and cardiac tissue following exposure to hyperbaric pressure. materials and methods:expression of cd11b and cd...

Endothelial cells present in brain are unique and differ from other peripheral tissues in a number of ways, which ensures specific brain endothelial barrier properties. Endothelial dysfunction is the earliest event in the initiation of vascular damage caused by inflammation. Various microRNAs (miRNA) have been discovered in different cellular components of the blood bran barrier (BBB). miRNAs a...

There is functional evidence suggesting that endothelial denudation stimulates inducible nitric oxide synthase (iNOS) activity in the vascular wall. In vitro studies have shown that iNOS expression in smooth muscle cells is reduced by endothelial cells. In the present study we have analyzed the time course of iNOS protein expression in the arterial wall after in vivo deendothelialization. Endot...

Candida albicans must penetrate the endothelial cell lining of the vasculature to invade the deep tissues during a hematogenously disseminated infection. We compared 27 C. albicans mutants with their wild-type parent for their capacity to damage endothelial cells in vitro and cause a lethal infection in mice following tail vein inoculation. Of 10 mutants with significantly impaired capacity to ...

tion and irrigation of the anterior chamber, and although lens design with surface protuberances may be of some importance, it is clear that a biophysical interaction between methacrylate and the corneal endothelial surface produces extensive cell damage. It appears that the methacrylate adheres instantaneously to the endothelial surface, and with separation of the two surfaces the anterior mem...

BACKGROUND AND PURPOSE The aim of this study was to test the hypothesis that, once formed, platelet aggregates may injure underlying cerebrovascular endothelium. Such injury could make the same site selectively attractive to the next wave of passing emboli or activated platelets. This vicious circle could account for repetitive, stereotypic symptoms in transient ischemic attacks. METHODS In p...

background: alzheimer’s disease (ad) is a progressive neurodegenerative disease and nowadays the role of endothelial cell (ec) injury has been proposed in pathological process in ad. peroxisome proliferator‑activated receptor‑γ (ppar‑γ) agonist has anti‑inflammatory properties through activation in glial cells and improves vascular function and prevent atherosclerotic disease progression. the a...
