The endothelial cells are the main regulator of vascular homeostasis, interacting with circulating cells on one hand, and cells present in the vascular wall, smooth muscle cells, on the other hand. Disturbing this tightly regulated equilibrium leads to endothelial dysfunction. Empagliflozin (10 mg/kg/day) treatment decreased the proportion of M1-polarized macrophages by 49% and increased that of anti-inflammatory M2 macrophages by 3.3-fold in adipose tissue, thus attenuating obesity-induced chronic inflammation in C57BL/6 J mice [82]. Tofogliflozin (0.005%) had no effect on chronic inflammation (inflammatory genes including Spp1 and Tnf-α were increased in visceral adipose tissue) and visceral adipose immunity, and had no influence on macrophage infiltration in visceral adipose tissues [106]. Substantial evidences support eNOS modulatory role of statins in affording cardiovascular protection. We use cookies to help provide and enhance our service and tailor content and ads. Endothelial cells also produce antithrombotic (NO and PGI2 both inhibit platelet aggregation) and prothrombotic molecules [von Willebrand factor, which promotes platelet aggregation, and plasminogen activator inhibitor-1 (PAI-1), which inhibits fibrinolysis] [5]. Endothelial cell sprouting is a fundamental process of physiological and pathological blood vessel growth. Interestingly, the cardioprotective effect of simvastatin was noted to be abrogated by genetic ablation of eNOS gene [77]. Short-term (7 days) luseogliflozin (0.1%) treatment inhibited the increased expression of inflammation-related genes, including F4/80 (a macrophage marker), IL-1β, IL-6, TNF-α, ICAM-1, PECAM-1, MMP2, and MMP9 in the aortas of NA/STZ-treated ApoE−/− mice [50]. Steady-state eNOS (EC 1.14.13.39) levels are regulated transcriptionally and posttranscriptionally, as well as epigenetically, since vascular endothelial cells perform epigenetic transmission of modifications during mitosis.8 In addition, the enzymatic activity of eNOS is regulated by protein–protein interactions.44,73–75, eNOS is mainly located in caveolae, and is tonically inhibited by caveolin-1. This contention is further supported by that fact that EPA improved vascular function in chronic type 2 diabetic Otsuka Long-Evans Tokushima fatty rats by maintaining the balance between endothelium-derived vasodilator and vasoconstrictor actions [75]. Vascular cells (endothelial, smooth muscle), fibroblasts, epithelial cells, nervous (afferent sensory) cells Levy and Zochodne (2000), and perhaps leukocytes (such as T lymphocytes) Prat et al (1999). Author information: (1)Department of Pediatrics, Albert Einstein College of Medicine, Bronx, New York 10461, USA. Abstract. Atorvastatin increased vascular BH4 bioavailability by upregulating GTP-cyclohydrolase I gene expression and activity, resulting in improved eNOS coupling and reduced generation of vascular superoxides. Mitochondria are the remnants of aerobic bacteria that invaded protoeukaryotic cells a billion years ago. 1. Both HDL2 and HDL3 stimulate secretion of PGI2 by endothelial cells [43] (Table 1, Figure 3e). Androgens modulate endothelial function, usually in a deleterious … Those stresses destroy the vital eNOS enzyme that produces nitric oxide, a signaling molecule that endothelial cells use to direct blood flow properly. Upon stimulation, endothelium releases H 2 S, leading to vasorelaxation mediated via activation of K + ATP and transient receptor membrane channel currents (Li et al. Blood must be contained inside the transporting vessels, but substances need to move in and out of it in a controlled manner. One measure of shear stability is the shear stress at which 50% of cells are detached. Indeed, since the early 1980s, the accumulating knowledge of the endothelial cell structure as well as of the functional properties of the endothelial cells shifted their role from a passive membrane or barrier to a complex tissue with complex functions adaptable to needs specific in time and location. In addition, rosuvastatin increased vascular endothelial nitric oxide production and subsequently attenuated myocardial necrosis following ischemia and reperfusion in the mouse [70]. In general, regional circulations regulate their flow so that they obtain required amounts of oxygen and nutrients, and all the mechanisms described can be invoked. Both types have unique functions throughout the circulatory system such as aiding in upholding homeostasis, fluid filtration, blood vessel tone and hormone trafficking. 6. Anti-inflammatory effects of SGLT2 inhibitors on atherosclerosis. NO diffuses into the smooth muscle cell and produces vascular relaxation by increasing concentrations of cGMP, via activation of soluble guanylate cyclase. This beneficial effect was paralleled with a normalisation of diabetes-induced increased RhoA activity and reduced eNOS production [13]. Declining endothelial function is the process that underlies a major cause of cardiovascular disease—atherosclerosis.” 3 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). Vascular endothelial cells serve as a protective barrier in blood-vessel walls and serve as an active source for the synthesis, metabolism, uptake, storage, and degradation of a number of vasoactive substances. The generation and progression of atherosclerotic lesions is a long-standing process characterized by the accumulation of excessive cholesterol crystals in the intima of arterial tissues. Likewise, mevastatin has protective effects on LDL-treated human endothelial cells by inducing eNOS expression and inhibiting lipid peroxidation [66]. Increasing interest in central nervous system localization and inducibility Ongali et al (2003). 88 Retinal capillaries are closely ensheathed by glial processes. Here, the shear stress patterns and its effect on gene expression and vascular function are reviewed. Oestrogens appear to have beneficial effects on endothelial function in both genders, by receptor-mediated and receptor-independent mechanisms, although this may require long-term administration in males. Moreover, both EPA and DHA increased plasma nitrite levels in SHRs, confirming their potential to generate NO [73]. Lu et al. 4). NCX 6560, a novel nitric oxide-releasing derivative of atorvastatin, exerted greater lipid-lowering, anti-thrombotic and anti-inflammatory effects than atorvastatin in various experimental settings, by reason of a large extent to release nitric oxide [83]. Empagliflozin treatment inhibited the proliferation of high glucose-treated vascular smooth muscle cells (VSMCs) in a dose-dependent manner in vitro via the inhibition of DNA synthesis in VSCMs, rather than by inducing apoptosis. The importance of the endothelium was first recognized by its effect on vascular tone. ETA receptors are located on vascular smooth muscle cells, and they mediate vasoconstriction. ETB receptors are located on endothelial cells and smooth muscle cells, and mediate both vasodilation and vasoconstriction. Die vaskulären endothelialen Wachstumsfaktoren (die englische Abkürzung VEGF für Vascular Endothelial Growth Factor ist auch im Deutschen üblich) sind eine Gruppe wichtiger Signalmoleküle, die hauptsächlich sowohl in der Vaskulogenese (de novo-Bildung des embryonalen Blutgefäßsystems und Lymphgefäßsystems) als auch in der Angiogenese und der Lymphangiogenese (dem Wachstum neuer … Table 14.3. Vascular endothelial growth factor (VEGF) has been identified as a major cytokine in the tumor microenvironment. Usually, Müller cells enhance the barrier function of vascular endothelia89 by the secretion of factors such as PEDF, thrombospondin-1, and glial cell line-derived neurotrophic factor (GDNF).90,91 However, in response to hypoxia, inflammation, or glucose deprivation, Müller cells produce factors such as vascular endothelial growth factor (VEGF) and tumor necrosis factor that increase vascular permeability.90,92,93 Müller cells are also a source of matrix metalloproteinases93,94 which degrade the tight junction protein, occludin.95, Laurent Camont, ... Anatol Kontush, in Trends in Molecular Medicine, 2011. Endothelial cells have been recently identified as targets for estrogens, and estrogen receptors have been demonstrated in endothelial cells from various vascular beds. The endothelium is a thin membrane that lines the inside of the heart and blood vessels. 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. These cells were used to fabricate functional tissue-engineered blood vessels that express key features of the progeria cardiovascular phenotype. eNOS = endothelial nitric oxide synthase; HMG-CoA = 3-hydroxy-3-methylglutaryl CoA; PKB = protein kinase B; PI3K = phosphotidyl inositol-3-kinase; LOX-1 = lectin like Ox-LDL; SR-B1 = scavenger receptor class B-type 1; E5′N = ecto-5′-nucleotidase; PPAR = peroxisome proliferator-activated receptor; PDK-1 = 3-phophoinositide-dependent kinase-1; ERK1/2 = extracellular signal-regulated kinase 1/2; TNF-α = tissue necrosis factor-α; t-PA = tissue plasminogen activator; PAI-1 = plasminogen activator inhibitor-1; ROS = reactive oxygen species; SOD = superoxide dismutase; NADPH oxidase = nicotinamide adenine dinucleotide phosphate oxidase. Through secretion of growth factors such as ET-1 (a potent vasoconstrictor with inotropic properties) and the expression of adhesion molecules, endothelial cells modulate vascular tone, thrombogenicity, and inflammation. Endothelialization on the vascular implants is of great importance for prevention of undesired postimplantation symptoms. Cristina M. Sena, ... Raquel Seiça, in Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2013. The statin therapy was suggested to participate in reversing the impaired functional regeneration capacities seen in patients with risk factors for coronary artery disease by explicitly interacting with progenitor cell function [84]. Leng et al. Bove´e,1,7,* and Valeria V. Orlova3,7,9,* Administration of rosuvastatin in the apoE−/− dyslipidemic mouse decreased the expression of caveolin-1 and as a result promoted the function of eNOS in vivo, with concurrent improvements in blood pressure and heart rate variabilities [71]. These cell functions are balanced between the regulation of physiological functions that maintain normal homeostasis and the endothelial dysfunction that is associated with pathobiology (Table 14.2). The vascular endothelium, a monolayer of endothelial cells (EC), constitutes the inner cellular lining of arteries, veins and capillaries and therefore is in direct contact with the components and cells of blood. 49 Shear stress is important in the pathogenesis of coronary artery disease and atherosclerosis, as atheromatous lesions tend to develop at areas of high shear stress. Mitochondria, Endothelial Cell Function and Vascular Diseases.pdf. ET-1 is a potent vasoconstrictor released by vascular endothelium. These functions include fluid filtration, such as in the glomeruli of the kidneys, blood vessel tone, hemostasis, neutrophil recruitment, and hormone trafficking. These shear stress activated-molecules include vasoactive compounds, extracellular matrix proteins and degradation enzymes, growth factors, and coagulation and inflammatory factors (Table 14.3). It must be noted that low-dose statin therapy might induce a pro-angiogenic effect through Akt activation and increased nitric oxide production [87]. 1. Of note, these proatherogenic compounds appear to have a dual effect: i) they first initiate impairment of vascular endothelium function, mainly caused by oxidative stress and inflammation; ii) subsequently, following excessive accumulation, they might contribute to foam cell formation, migration and proliferation of vascular SMCs, fibrous cap formation, and modulation of ECM, leading to plaque progression and instability with eventual rupture (Fig. The authors of this study suggested that atorvastatin-mediated induction of renal nitric oxide system through Rho-kinase inhibition and Akt activation may contribute to the antihypertensive and renoprotective effects of statins [14]. Interventional studies with dietary fatty acids have shown that these molecules have varying effects on vascular function. The endothelial cells are part of the blood-brain barri… 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. Atorvastatin reduced both intramyocardial inflammation and myocardial fibrosis in rats with diabetic cardiomyopathy that resulted in improved left ventricular function. In addition, atorvastatin afforded cardioprotection in rats subjected to myocardial ischemia-reperfusion by implicating cyclooxygenase-2-mediated signaling mechanism, which is downstream to NOS signals [75]. Nucleotide oligomerization domain-like receptor 3 (NLRP3) inflammasome participates in the inflammatory response associated with the pathogenesis of atherosclerosis [98]. However, phlorizin (400 mg/kg/day) treatment did not reverse the elevation in Vcam-1, Tnf-α, and Il-6 mRNA expression in the aortic roots of ApoE−/−mice [86]. A substance that damages or destroys endothelial cells to the extent that vasodilatory responses are altered could conceivably cause significant decreases in blood flow and subsequent tissue damage in certain organs. In addition, the loss of functional endothelial cells seems to transform normal vasodilator responses into potent vasoconstrictor activity. M1 macrophages induce the production of pro-inflammatory factors and ROS, favoring the progression of inflammation. Endothelial nitric oxide synthase (eNOS) expression levels are reduced in S. mansoni-infected mouse mesenteric endothelial cells. Fig. The main trigger of eNOS enzymatic activity is the increase in the intracellular calcium levels induced either by metabotropic G protein-coupled receptors or by ionotropic receptors. 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. Potassium channels also are present in endothelial cells. angioblasts or endothelial cells predominated where segments Liver Organogenesis Promoted by Endothelial Cells Prior to Vascular Function Kunio Matsumoto,1,2* Hideyuki Yoshitomi,1* Janet Rossant,1,3 Kenneth S. Zaret1† 1Cell and Developmental Biology Program, Fox Chase Cancer Center, 7701 Burholme Avenue, Philadelphia, PA 19111, USA. The eNOS-modulating potential of fish oil was further confirmed by the fact that administration of dietary fish oil prevented the dysfunction of vascular endothelium in fructose-fed rats by virtue of its ability to increase the expression of eNOS and decrease oxidative stress [30]. Nitric oxide (NO) is a soluble gas continuously synthesized from the amino acid L-arginine in endothelial cells by the constitutive calcium-calmodulin-dependent enzyme nitric oxide synthase (NOS). The endothelium is not only a mere barrier between blood and tissues but also an endocrine organ. Fish oil supplementation was shown to ameliorate glucocorticoid-induced hypertension by improving endothelium-dependent relaxation in the rat aorta [79]. The correlation between ET-1 expression levels and the degree of CHF has been well established.56 ET-1 contributes to essential hypertension, CAD, and chronic renal failure progression and promotes cardiac fibrosis.57 Furthermore, endothelial cells release proangiogenic growth factors that affect both heart size and cardiac function. Endothelial cells (ECs) make up the innermost layer throughout the entire vasculature. Finally, the potential therapeutic strategies to improve mitochondrial function in endothelial cells and vascular diseases are also discussed, with a focus on mitochondrial-targeted antioxidants and calorie restriction. Usually, Müller cells enhance the barrier function of vascular endothelia 89 by the secretion of factors such as PEDF, thrombospondin-1, and glial cell line-derived neurotrophic factor (GDNF). vascular endothelial growth factor and the suppressed production of tumor necrosis factor-α and IL-6. Pitchai Balakumar, Gaurav Taneja, in Free Radical Biology and Medicine, 2012. Abstract. Andreas Reichenbach, Andreas Bringmann, in Retina (Fifth Edition), 2013, Vascular leakage caused by opening of the tight junctions between vascular endothelial cells and/or by increased vesicular transport of serum proteins across vascular endothelia is an important pathogenic mechanism of retinal edema.88 Retinal capillaries are closely ensheathed by glial processes. Autocrine and paracrine functions of vascular endothelial growth factor (VEGF) in renal tubular epithelial cells. Immunological staining of the sections from aortic roots confirmed the effect of canagliflozin on MCP-1 and TIMP-1. Disruption of coordinated tissue growth and angiogenesis in the heart contributes to the progression from adaptive cardiac hypertrophy to CHF.58 In response to pressure overload, complete blockade promotes the transition from compensatory cardiac hypertrophy to failure.59, Lastly, vascular smooth muscle cells can move from the tunica media to the intima, where they contribute to vascular remodeling by synthesis of extracellular matrix components, specifically proteoglycans.60 When activated by proinflammatory cytokines, the smooth muscle cells produce more collagen, leading to arterial fibrosis and the release of matrix-remodeling proteinases.61. Regulation of the blood–retinal barrier Vascular leakage caused by opening of the tight junctions between vascular endothelial cells and/or by increased vesicular transport of serum proteins across vascular endothelia is an important pathogenic mechanism of retinal edema. 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. 50 It is believed that laminar and disturbed flows regulate endothelial function differently. Scheme of key steps promoting plaque vulnerability induced by oxysterols and HNE. In this study, we sought to investigate the status of vascular endothelial function in COVID-19 patients from a non-invasive approach. This finding suggests endothelins are primarily effective at the local site of release. Likewise, atorvastatin upregulates eNOS by inducing Rho-kinase inhibition and Akt activation in the kidney of spontaneously hypertensive rats [14]. Alterations of endothelial cells and the vasculature play a central role in the pathogenesis of a broad spectrum of the most dreadful of human diseases, as endothelial cells have the key function of participating in the maintenance of patent and functional capillaries. 1. Endothelial cells are normally exposed to mechanical forces that affect their function. Indeed, since the early 1980s, the accumulating knowledge of the Endothelial cells release substances that control vascular relaxation and contraction as well as enzymes that control blood clotting, immune function and platelet (a colorless substance in the blood) adhesion. Salvatori,2,6,8 Xu Cao,3,6 Francijna van den Hil,3 Inge H. Briaire-de Bruijn,1 Danielle de Jong,4 Hailiang Mei,5 Christine L. Mummery,3 Karoly Szuhai,4 Judith V.M.G. Taken together, these studies confirmed the pivotal role of statins-mediated upregulation and activation of eNOS and generation of nitric oxide in preventing cardiovascular complications. It suggests that atorvastatin directly improves vascular nitric oxide bioavailability and reduces oxidative stress through BH4-mediated induction of eNOS coupling [81]. Indeed, estrogens have direct effects on the vascular wall, including inhibition of vascular smooth muscle cell proliferation, powerful vasodilator activity, inhibition of inflammation, antioxidant properties, and accelerated endothelial cell recovery after vascular injury (Mendelsohn and Karas, 1999; Meyer et al., 2006). NO is a labile humoral factor produced by nitric oxide synthase (NOS) from Larginine in the vascular endothelial cell. Vascular endothelial cells (ECs), which are embryologically derived from splanchnopleuric mesoderm, form a thromboresistant barrier on the surface of the vascular tree. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Treatment with ipragliflozin (1 mg/kg/day) suppressed intra-plaque macrophage infiltration, which is an indicator of foam cell formation in the aortic roots of streptozotocin-induced diabetic ApoE−/− mice. Vascular endothelial cells line the entire circulatory system, from the heart to the smallest capillaries.. Dapagliflozin treatment reversed these changes, except for CD36 and ABCG1 in macrophages from diabetic ApoE−/− mice [44]. We hypothesize that many GWAS loci associated with vascular diseases modulate endothelial functions. Foam cell formation was approximately 3–4-fold higher in macrophages from diabetic ApoE−/− mice and diabetic db/db mice compared with that in macrophages from non-diabetic mice [44]. Content may be subject to copyright. Endothelial cells from certain arteries and veins seem to be directly involved in the decrease of vascular tone … Nasiri-Ansari demonstrated that canagliflozin (10 mg/kg/day) treatment for 5 weeks significantly reduced atherosclerosis progression in ApoE−/− mice. Empagliflozin (1–3 mg/kg/day) treatment reduced the size of the adipocytes in abdominal visceral adipose tissues, reduced the area occupied by lipid droplets, and decreased the number of histiocytes in the atherosclerotic lesions in ApoE−/− mice compared to the control or glimepiride-treated groups [47]. This consistent force results in the alignment of cells in the flow direction.22,125 Importantly, fluid shear stress application for 24 h also causes endothelial cell nuclei to flatten, lengthen, and increase up to 50% in stiffness.126 What is fascinating is that these changes persist even after nuclei are isolated, suggesting that stable nuclear reorganization or remodeling occurred.126 Some of these changes may be facilitated by reorganization of the actin cytoskeleton, as related to the magnitude of shear stress. 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. Your endothelial cells are responsible for the release of different factors geared to maintaining normal endothelial function. It has significantly impeded long-term success … Lox-1, CD36, and ACAT1 were up-regulated, whereas ABCA1 and ABCG1 were down-regulated in the peritoneal macrophages of diabetic ApoE−/− mice and diabetic db/db mice. In a recent study, a fish oil-rich diet was shown to reduce oxidative stress in apoE−/− mice and decrease the lipoxidative damage [74]. Rosuvastatin has been demonstrated to prevent ischemia-reperfusion-induced myocardial injury by upregulating myocardial eNOS expression in the mouse [70]. Fig. Given the multiple functions of receptors regulating Rac1 in pericytes, vascular smooth muscle cells, and macrophages (18 – 20), we decided to explore the direct function of Rac1 in endothelial cells by deleting the Rac1 gene specifically in this cellular compartment. The hemodynamic effects of ET-1 are mediated by at least two distinctive receptor populations: ETA and ETB. Vascular permeability in HUVECs was measured in an in vitro assay of leakage to fluorescein-dextran at 60 minutes after addition of the dye, a time point at which leakage is prominent.
