vascular endothelial cells function

The authors of this study concluded that atorvastatin can improve cardiac function in an experimental model of diabetic cardiomyopathy by inhibiting RhoA signaling and upregulating eNOS expression, independently of its cholesterol-lowering capacity [13]. Interventional studies with dietary fatty acids have shown that these molecules have varying effects on vascular function. Vascular endothelial (VE)‐cadherin, a major endothelial adhesion molecule, regulates vascular permeability, and increased vascular permeability has been observed in several cancers. Ipragliflozin (3 mg/kg/day) administration reduced the increase of inflammatory molecules (ICAM-1, VCAM-1 and MCP-1), increased Akt and eNOSSer1177 phosphorylation (which increases eNOS activity), and decreased ROS production in the abdominal aortae of STZ-induced diabetic mice. Pericytes support endothelial cell barrier formation and maintenance through paracrine and contact-mediated signaling and are critical to microvascular integrity.

It is worthwhile to note that low-dose simvastatin therapy significantly improved survival rate and cardiac function and reduced cardiac hypertrophy via eNOS-dependent mechanism in a murine model of heart failure [77]. When expressed, proteins such as the intercellular adhesion molecule-1 (ICAM-1) and the vascular cell adhesion molecule-1 (VCAM-1) promote inflammation by recruiting immune cells. EDHF has not yet been identified, but current evidence suggests the action of EDHF is dependent on K+ channels23 (see Figure 18-8). The underlying molecular mechanisms responsible for the diverse phenotypes of ECs from different organs are not well understood. Available via license: CC BY 3.0.

Vascular Endothelial Cell Function and Thrombosis. Author information: (1)Department of Pediatrics, Albert Einstein College of Medicine, Bronx, New York 10461, USA. Vascular endothelial cells line the entire circulatory system, from the heart to the smallest capillaries.. There are two separate and distinct states of macrophage polarization: M1 (classically activated) and M2 (alternatively activated). These cells have very distinct and unique functions that are paramount to vascular biology. Methods Male vascular endothelial cell-specific Pdpk1-knockout mice (Tie2 +/−/Pdpk1flox/flox mice) and their wild-type littermates (Tie2 −/−/Pdpk1flox/flox mice; control) were used for this study. Fig. Piezo1 Mediates Increased Lung Endothelial Permeability in Response to Vascular Pressure Rise. Another pathway involved in maintaining eNOS activity and endothelium-dependent vasorelaxation in endothelial cells is mediated by ABCG1 and involves cholesterol efflux by mature α-HDL [42]. We find that early endothelial cells in mouse embryos surround newly specified hepatic endoderm and delimit the mesenchymal domain into which the liver bud grows. Increasing experimental evidence points to a significant contribution of oxysterols and HNE in development of the atherosclerotic plaque. Introduction. Endothelial cells (ECs) covering the inner surface of blood vessels are constantly exposed to shear stress, the frictional force generated by flowing blood, and they have the property of sensitively changing their morphology and function in response to changes in shear stress. 88 Retinal capillaries are closely ensheathed by glial processes. However, another study obtained contradictory results; empagliflozin treatment (0.1–100 μmol/l) did not affect rat aortic smooth muscle cell (RAoSMC) proliferation, platelet-derived growth factor-directed migration in RAoSMCs, or vascular endothelial growth factor-induced proliferation in HUVECs (human umbilical vein endothelial cells) [47] (Fig. 2. The authors speculated that the anti-atherosclerotic effect of the drug was at least partially due to the attenuation of oxidative stress [101]. But endothelial function declines with age, through the ravages of chemical, metabolic, and inflammatory stresses. R.E. Pitchai Balakumar, ...

Anti-inflammatory effects of SGLT2 inhibitors on atherosclerosis. Endothelial cells in direct contact with blood are called vascular endothelial cells whereas those in direct contact with lymph are known as lymphatic endothelial cells. Endothelial cells are responsible for a number of physiological functions, including: 1) regulation of vascular tone through balanced production of vasodilators and vasoconstrictors; 2) control of blood fluidity and coagulation through production of factors that regulate platelet activity, the clotting cascade, and the fibrinolytic system; and 3) regulation of inflammatory processes through expression of cytokines and adhesion molecules. cAMP elevation by beta-adrenergic agents stimulating G s protein–coupled receptors reduces vascular leakage. Marchant, J. Zhu, in Comprehensive Biomaterials, 2011, Vascular EC in vivo are subjected to physical forces related to blood flow.104–107 Vascular ECs sense these forces and respond through phenotypic alterations in morphology and alignment, mechanical properties, and signal transduction.106 Shear stability has also been related to integrin–ligand interaction, although the relationship plateaus at high adhesivity and does not exhibit bimodal behavior. A recent study suggested that EPA might have the potential to repair hyperlipidemia-induced endothelial dysfunction of the carotid artery of rabbits on a high-cholesterol diet [80]. The endothelium is a thin membrane that lines the inside of the heart and blood vessels. 50 It is believed that laminar and disturbed flows regulate endothelial function differently. These results provided the framework to understand the functional role of Epac/Rap-dependent and PKA-independent pathways in endothelial cell barrier function. Fig. Rosuvastatin has been demonstrated to prevent ischemia-reperfusion-induced myocardial injury by upregulating myocardial eNOS expression in the mouse [70]. NLRP3 gene knockdown has been confirmed to prevent plaque formation and inhibit the expression of proinflammatory cytokines, leading to the stabilization of atherosclerotic plaques in mice [99]. The authors suggested that fish oil-associated upregulation of eNOS and enhanced generation of NO could contribute to the maintenance of vascular homeostasis and prevention of arterial disease [29]. An important difference exists in the capacity of the two HDL subclasses to modulate endothelial production of thromboxane A2, a vasoconstrictor and prothrombotic mediator, that is enhanced by HDL3 and decreased by HDL2 [37]. However, its most striking property is its sustained hypertensive action. Endothelial nitric oxide synthase (eNOS) expression levels are reduced in S. mansoni-infected mouse mesenteric endothelial cells. Depicted here the involvement of multifaceted signaling mechanisms with a central role of eNOS in statins-mediated cardiovascular protection. Yingxiu Kang, ... Xiaoxiao Song, in Vascular Pharmacology, 2020. Moreover, both EPA and DHA increased plasma nitrite levels in SHRs, confirming their potential to generate NO [73]. Luseogliflozin (0.1%) reduced triglyceride accumulation in the aortic roots to similar levels to untreated ApoE−/− mice as determined by Oil Red O staining [50]. Shear Stress-Regulated Factors in Endothelium, NO—endothelial Nitric Oxide Synthase (eNOS), Granulocyte Monocyte-Colony Stimulating Factor (GM-CSF), Insulin-Like Growth Factor Binding Protein (IGFBP), Protease-Activated Receptor-1—thrombin receptor (PAR-1), Extracellular superoxide dismutase (ecSOD), Sterol regulatory element binding protein (SREBP), Platelet/endothelial cell adhesion molecule (PECAM-1), Ashley Kaminski, ... Jan Lammerding, in Progress in Molecular Biology and Translational Science, 2014, Vascular endothelial cells experience constant fluid shear stress. Nasiri-Ansari demonstrated that canagliflozin (10 mg/kg/day) treatment for 5 weeks significantly reduced atherosclerosis progression in ApoE−/− mice. Your endothelial cells release nitric oxide, von Willebrand factors, and adhesion molecules, which all contribute to vascular homeostasis Timon Seeger, ... Joseph C. Wu, in Cardiac Electrophysiology: From Cell to Bedside (Seventh Edition), 2018, Vascular endothelial cells are strategically positioned between the vascular wall and the bloodstream, playing a critical role in the pathogenesis of cardiac hypertrophy, remodeling, and failure. Intriguingly, EPA and DHA were shown to decrease plasma levels of ADMA in spontaneously hypertensive rats (SHRs). Another SGLT-2 inhibitor, empagliflozin (0.03%), significantly reduced superoxide production in thoracic aortae (P < 0.01), significantly attenuated the impaired function of vascular endothelium, and partially improved vascular endothelium-dependent relaxation impaired by acetylcholine in db/db mice [100]. In addition, being the interface between blood and tissue, they are mostly susceptible to changes in blood composition and in blood flow. It is produced both in vascular endothelial cells and smooth muscle cells, and similar to NO, acute production of H 2 S from vascular endothelial cells is triggered by muscarinic cholinergic activation (Wang 2009). Thus, it may be suggested that ω-3-PUFAs could enhance endothelium-dependent relaxation in hypertensive individuals with high ADMA levels by enhancing NO generation. Further, it has been suggested that atherosclerosis induced by chronic inhibition of NOS using N(omega)-nitro-l-arginine methyl ester (L-NAME), a NOS inhibitor, in moderately hypercholesterolemic rabbits is suppressed by pitavastatin via inhibition of macrophage accumulation and macrophage foam cell formation [72].

Gabriella Leonarduzzi, in, Endothelial dysfunction — A major mediator of diabetic vascular disease, Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, Fish oil and vascular endothelial protection: Bench to bedside. The excessive production of ET-1 affects vascular tone, which may lead to coronary vasospasm [77]. Attracted by growth factors such as vascular endothelial growth factor-A (VEGF-A) secreted from hypoxic tissues, endothelial cells (ECs) break out of the quiescent vessel wall to form new vessel branches (Ferrara et al., 2003; Koch and Claesson-Welsh, 2012). Here, the shear stress patterns and its effect on gene expression and vascular function are reviewed. In addition, fish oil increased aortic eNOS expression and NO production in apoE−/− mice [74].
