Endothelial dysfunction and thrombosis in patients with COVID-19-brief report. 2022; 2090792. https://doi.org/10.1080/21688370.2022.2090792. Vitamin C is an essential, safe and inexpensive nutrient [152] that has anti-oxidant, anti-infectious, anti-inflammatory, anti-thrombotic and immune-modulatory effects [153]. Emerging evidence has suggested that thinning of endothelial glycocalyx layer is associated with COVID-19, and thus the glycocalyx integrity was perceived as an important therapeutic target in COVID-19 [109, 110]. Int J Mol Sci. It has been reported that the secretion of multiple markers of endothelial activation/dysfunction is elevated in COVID-19 patients, such as D-dimer (marker of coagulopathy and systemic thrombosis), vWF (a primary component of coagulation pathway and mediator of vascular inflammation and thrombo-inflammation released from Weibel-Palade bodies), factor VIII (marker of coagulation), PAI-1 (a marker of endothelial damage and senescence), soluble thrombomodulin (sTM), soluble P-selectin (marker of platelet and endothelial activation), soluble ICAM1 (sICAM1, marker of endothelial inflammation), soluble VCAM1 (sVCAM1, marker of endothelial inflammation), angiopoietin-2 (Ang-2, marker of angiogenesis and thrombosis), soluble E-selectin (sE-selectin, marker of endothelial inflammation), ET1 (a potent vasoconstrictor), VEGF-A (marker of angiogenesis and endothelial hyperpermeability), IL-6 and IL-8 (markers of endothelial inflammation), MCP-1 (marker of endothelial inflammation), resistin (an adipokine associated with endothelial damage and vasoconstriction), nitrosylhemoglobin (HbNO), lactate, and syndecan-1 (marker of endothelial glycocalyx damage) [19, 23, 80, 102,103,104,105,106]. 8600 Rockville Pike These evidences suggest that inhibition of complement pathway could be an effective strategy to manage endothelial injury/endotheliitis accompanying COVID-19 [97]. Management requires the immediate reduction of core temperature. ACE2 is highly expressed in renal tissues, the injury of which leads to proteinuria, hematuria and abnormal renal radiography [38]. SARS-CoV-2 spike protein induces degradation of junctional proteins that maintain endothelial barrier integrity. Increased heparanase activity and heparan sulphate level have been observed in plasma derived from COVID-19 patients [113]. Studies in the past two years altogether provide important mechanistic insights into the pathogenesis of COVID-19 and yield promising new therapeutic targets (Fig. Of translational relevance, several candidate drugs which are endothelial protective have been shown to improve clinical manifestations of COVID-19 patients.

Metformin in cardiovascular diabetology: a focused review of its impact on endothelial function. Researchers from the University of Milan, Italy have found a link between thyroid dysfunction and moderate-to-severe COVID-19. Statins are prescribed as the first-choice treatment for patients with hypercholesterolemia and coronary artery disease due to their lipid-lowering and pleiotropic anti-inflammatory, antioxidant, anti-thrombotic and immune-modulatory effects. However, COVID-19 serum induced glycocalyx destruction was reversed by a non-anticoagulant heparin fragment [113]. A new study by investigators from the Smidt Heart Institute at Cedars-Sinai suggests long COVID-19 might be caused by a dysfunction of . Since atherosclerosis is an important cause for coronary artery disease, it might be of interest to investigate whether COVID-19 can accelerate the development of endothelial dysfunction and new onset atherosclerosis [26].

It is possible that these cytokines will disrupt the integrity of various types of junctional proteins, including VE-cadherin, ZO-1, -catenin and gap junction proteins. : Experimental results and a cautionary note on challenges in translational research. Published evidence indicates that Severe Acute Respiratory Syndrome-Corona Virus (SARS-CoV-2) infection causes endothelial cell (EC) injury in the Coronavirus Disease 2019 (COVID-19). In light of the important contribution of endothelial dysfunction to COVID-19 and its sequelae, we overviewed, in this article, the pivotal role and mechanistic basis of endothelial dysfunction in COVID-19 and its multi-organ complications and markers of endothelial activation. A recent study has shown that SARS-CoV-2-infection of human brain microvascular ECs showed augmented caspase 3 cleavage and apoptotic cell death of endothelial cells. Tocilizumab improves oxidative stress and endothelial glycocalyx: A mechanism that may explain the effects of biological treatment on COVID-19. The evidence discussed below support both a direct mechanism (virus infection via ACE2, L-SIGN and other receptors) and indirect mechanisms (such as cytokine storm) are involved in SARS-CoV-2 infection associated endothelial dysfunction (Fig. Several histopathological evidence has supported direct viral infection of endothelial cells, for example, electron microscopy of kidney tissues shows the existence of endotheliitis and viral particles in ECs [52]. These findings suggest that fluvoxamine can be repurposed as novel anti-COVID-19 drugs although further studies are warranted to assess the therapeutic potential of fluvoxamine in patients [151]. Even in convalescent COVID-19 patients, the level of SDC-1 levels was significantly elevated compared to healthy controls, demonstrating the existence of persistent endothelial damage after severe COVID-19 progression [71]. 2021;321:L477l84. Another recent study has demonstrated that, SARS-CoV-2 infection in human brain microvascular ECs increased the secretion of angiogenic factors and altered mitochondrial dynamics, such as increased the expression of mitofusin-2 (a protein involved in a maintenance of an appropriate mitochondrial architecture, metabolism and signaling) and fostered the formation of mitochondrial networks [65]. Evidently, based on the cytokine storm in severe or critically ill COVID-19 patients, targeted inhibition of pro-inflammatory cytokines, such as IL-1, IL-6 and downstream signal transduction pathways appears to be important avenues [93]. Kang S, Kishimoto T. Interplay between interleukin-6 signaling and the vascular endothelium in cytokine storms. Recent studied have shown that colchicine is able to reduce the length of stay in hospitalized COVID-19 patients with the possible mechanism of inhibition of NLRP3 inflammasome and resultant IL-1 production [143, 144]. However, the underlying cellular and molecular mechanisms driving this condition are . However, data from a small study cohort demonstrate that the majority of patients with acute myocardial infarction developed symptoms after COVID-19 vaccinations [32]. Human lung microvascular endothelial cells (HLMVEC) are activated after infection with the S1 protein or S1 infected human macrophages, evidenced by increased expression of pro-coagulant marker (tissue factor), and cytokines/chemokines (ICAM-1, VCAM-1 and MCP1) [54]. Nat Neurosci. [132] and the expert recommendations from the professional cardiovascular societies, supporting that ACEIs and ARBs does not alter SARS-CoV-2 infection and should not be discontinued in COVID-19 patients [133]. Zhang P, Zhu L, Cai J, Lei F, Qin JJ, Xie J, et al. 2022;3:100663. We also present emerging therapeutic agents and therapeutic targets which are directed at reducing the consequence of endothelial dysfunction/endotheliitis/endotheliopathy. Since the outbreak of COVID-19 in early 2020, emerging evidence has demonstrated endothelial dysfunction as the unifying and central mechanism of COVID-19 [6]. Results of the first interim analysis. Respir Med. Kaundal RK, Kalvala AK, Kumar A. Here, we reviewed the potential mechanism of endothelial activation in COVID-19 by overviewing the most recent literature, with the aim to provide targeted therapies (Fig. Falleni M, Tosi D, Savi F, Chiumello D, Bulfamante G. Endothelial-mesenchymal transition in COVID-19 lung lesions. Lancet Rheumatol. 2020;96:6157.

Mller R, Rink G, Uzun G, Bakchoul T, Wuchter P, Klter H, et al. Furthermore, spike protein S1 receptor-binding domain (S1-RBD) infection in mouse brain microvascular ECs induced the degradation of endothelial junctional proteins (VE-Cadherin, junctional adhesion molecule-A, Connexin-43 and PECAM-1), thereby impaired endothelial barrier function and caused vascular leakage and endotheliitis in COVID-19 patients [57, 58]. The purpose of this review is to provide a latest summary of biomarkers associated with endothelial cell activation in COVID-19 and offer mechanistic insights into the molecular basis of endothelial activation/dysfunction in macro- and micro-vasculature of COVID-19 patients. Excessive production of mtROS causes oxidative stress that perpetuates ECs inflammation, senescence and dysfunction. 2020;73:123140. Neurological implications of COVID-19: role of redox imbalance and mitochondrial dysfunction. In another translational study, treatment of human pluripotent stem cell-derived endothelial cells (hECs) with SARS-CoV-2 leads to enriched gene program involved in immunity, inflammation and viral response (such as TNF-, IFNs and NF-B signaling pathway). This leads to decreased expression of VE-cadherin in lung endothelial cells. Jothimani D, Venugopal R, Abedin MF, Kaliamoorthy I, Rela M. COVID-19 and the liver.
