A major cause of respiratory failure during influenza A virus (IAV) infection is damage to the epithelial-endothelial barrier of the pulmonary alveolus. Damage to this barrier results in flooding of the alveolar lumen with proteinaceous oedema fluid, erythrocytes and inflammatory cells. To date, the exact roles of pulmonary epithelial and endothelial cells in this process remain unclear.Here, w...

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...

BACKGROUND Endothelial dysfunction is present in established rheumatoid arthritis, but it is not clear at what stage of the disease this abnormality develops. We set out to determine whether endothelial damage/dysfunction is present in a group of patients with early arthritis (EA) (new onset inflammatory arthritis, EA). MATERIALS AND METHODS Eighteen patients with EA, 48 healthy controls and ...

The endothelial cell layer is a multifunctional barrier between the blood stream and the vascular wall. Reactive oxygen species can damage endothelial cells and may so potentiate atherosclerotic lesion formation. Therefore, we established an in vitro model for the qualitative and quantitative investigation of oxidative DNA damage and repair in human coronary arterial endothelial cells (CAEC). O...

INTRODUCTION Chemotherapy-related endothelial damage contributes to the early development of cardiovascular morbidity in testicular cancer patients. We aimed to identify relevant mechanisms of and search for candidate biomarkers for this endothelial damage. METHODS Human micro-vascular endothelial cells (HMEC-1) were exposed to bleomycin or cisplatin with untreated samples as control. 18k cDN...

STUDY OBJECTIVES This study tries to assess the endothelial function in vivo using flow-mediated dilatation (FMD) and several biomarkers of endothelium formation/restoration and damage in patients with obstructive sleep apnoea (OSA) syndrome at baseline and after three months with CPAP therapy. DESIGN Observational study, before and after CPAP therapy. SETTING AND PATIENTS We studied 30 pat...
