Abstract Background. The blood-brain barrier represents the selective diffusion barrier at the level of the cerebral microvascular endothelium. Other functions of blood-brain barrier include transport, signaling and osmoregulation. Endothelial cells interact with surrounding astrocytes, pericytes and neurons. These interactions are crucial to the development, structural integrity and function of the cerebral microvascular endothelium. Dysfunctional blood-brain barrier has been associated with pathologies such as acute stroke, tumors, inflammatory and neurodegenerative diseases. Conclusions. Bl

The regulatory interplay between laminar shear stress and proinflammatory cytokines during homeostatic maintenance of the brain microvascular endothelium is largely undefined. We hypothesized that laminar shear could counteract the injurious actions of proinflammatory cytokines on human brain microvascular endothelial cell (HBMvEC) barrier properties, in-part through suppression of cellular redox signaling. For these investigations, HBMvECs were exposed to either shear stress (8 dynes/cm2, 24 hours) or cytokines (tumor necrosis factor-α (TNF-α) or interleukin-6 (IL-6), 0 to 100 ng/mL, 6 or 18

SummaryEndothelial cells produce platelet-activating factor (PAF), which is the key process in the interactions between the vascular wall and blood cells. To examine the production of PAF in brain microvasculature we have cultured brain endothelial cells and performed a comparative study with aortic endothelial cells. Fresh porcine brain was homogenized, and microvascular endothelial cells were separated by enzyme digestion. The cells were cultured in medium containing epidermal growth factor and bovine brain extract. Endothelial cells from the aorta of the same animal were cultured in a simil

The endothelium plays an important role in the modulation of vascular tone and blood cell activation. Extensive work has demonstrated that the release of endothelium-derived relaxing factor (EDRF) from the endothelium is evoked by a number of physical and chemical stimuli requiring Ca2+. Because endothelial cells do not express voltage-dependent Ca2+ channels, Ca2+ influxes following receptor activation may be facilitated by cell hyperpolarizations mediated by the activation of K+ conductances. There has been recent interest in the role of ATP-sensitive K+ channels (KATP) suggesting that KATP

Microvascular endothelial cells at the blood–brain barrier exhibit a protective phenotype, which is highly induced by biochemical and biomechanical stimuli. Amongst them, shear stress enhances junctional tightness and limits transport at capillary-like levels. Abnormal flow patterns can reduce functional features of macrovascular endothelium. We now examine if this is true in brain microvascular endothelial cells. We suggest in this paper a complex response of endothelial cells to aberrant forces under different flow domains.

SummaryEnterohaemorrhagic Escherichia coli (EHEC) cause haemolytic uraemic syndrome (HUS),a thrombotic microangiopathy resulting from endothelial injury in the renal glomeruli and other organs. EHEC virulence factors that damage the microvascular endothelium play therefore major roles in the pathogenesis of HUS.We identified an EHEC strain that vacuolates and kills primary human glomerular microvascular endothelial cells (GMVECs) and a human brain microvascular endothelial cell (HBMEC) line. Because the vacuolating effect closely resembles those elicited on other cells by the vacuolating cytot

This study investigated whether HSYA protected ZO-1 by targeting ROS-generating NADPH oxidases (NOXs).

Impaired formation of PKa in dengue-plasmas correlated with the presence of cleaved Factor XII and high mol

AbstractGrowth hormone releasing hormone is a hypothalamic neuropeptide, which regulates the release of growth hormone from the anterior pituitary gland.

There is a correlation between adherent Pf-IRBC and increased expression of intercellular cell adhesion molecule 1 (ICAM-1), which is also a receptor for Pf-IRBC on human brain microvascular endothelial cells (HBMEC). The underlying mechanism for the increased ICAM-1 expression has not been clearly defined. Therefore, we investigated the mechanisms of ICAM-1 expression on isolated HBMEC after exposure to Pf-IRBC.

Abstract Triple negative breast cancer (TNBC) is subtype of breast cancer that has no expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). TNBC metastasizes to specific tissues such as brain and bone in a process termed organotropism. In this process, TNBC cells cross the vascular endothelium; transport across endothelial cells is, in part, regulated by cell-cell junctions. The TNBC cell secretome has been shown to contain factors such as vascular growth factor (VEGF) and matrix metalloproteinases (MMPs) that could play a role i

Most neurological diseases, including stroke, lead to some degree of blood–brain barrier (BBB) dysfunction. A significant portion of BBB injury is caused by inflammation, due to pro-inflammatory factors produced in the brain, and by leukocyte engagement of the brain endothelium. Recently, microRNAs (miRNAs) have appeared as major regulators of inflammation-induced changes to gene expression in the microvascular endothelial cells (BMVEC) that comprise the BBB. However, miRNAs’ role during cerebral ischemia/reperfusion is still underexplored. Endothelial levels of miR-98 were significantly alter
