Kang S , Lazareth I The endothelium is an important target for SARS-CoV-2 infection, and vascular disorders are a major problem in COVID-19. , Tresoldi M , Püschel K When the endothelial cells undergo the cytopathic effect of a viral infection such as SARS-CoV-2, or encounter pathogen-associated molecular patterns (PAMPs) derived from viruses or bacteria such as lipopolysaccharide, proinflammatory cytokines such as IL-1 or TNF, or damage-associated molecular patterns (DAMPs) derived from dead or dying cells, the endothelial cells become activated. Epub 2020 Sep 12. IL-1 also causes substantial increases in production by endothelial and other cells of IL-6, the instigator of the hepatocyte acute phase response. , Lundstrom A , Neagoe RAI , Bauer E Great attention has been paid to endothelial dysfunction (ED) in coronavirus disease 2019 (COVID-19). , Mann DL The endothelial monolayer that lines the intima of arteries, veins, and microvessels measures up to 7000 m 2 in surface area.

COVID-19; SARS-CoV-2; coagulation; cytokines; endothelial dysfunction; thrombosis; von Willebrand factor. , Weber A , Le Pavec J SUMMARY: Coronavirus disease 19 (COVID-19) is a pandemic originating in Wuhan, China, in December 2019. In: Zipes DP , Huang J Vascular endothelial cell pathology in COVID-19 The vascular pathology of COVID-19 is a topic of great interest [ 37 ]. , Capretti G Yet how SARS2 dysregulates vascular functions causing an acute respiratory distress syndrome (ARDS) in Covid-19 patients remains an enigma. The Multifaceted Covid-19 We see all imaginable symptoms with Covid-19, which is supposed to be a pneumonia disease. , Schoenborn M , Woods RJ , Watson SP , Zhang P To explain these widespread injuries, researchers are studying how the virus affects the vascular … , Huang LS , von Hundelshausen P , Gerakari S , Kanonidis I , Naccache J-M P-selectin (CD62P) and L-selectin (CD62L) also mediate interaction of the endothelial surface with various classes of blood leucocytes. , Farina N , Schwartz RE , Mehran R , Stulz P , Zheng X , Brown H , Kaul DR , Zhao G-N Thus, disordered endothelial homeostasis provoked by cytokines provides a common thread in numerous complications of COVID-19.13,50–52. “We found greater numbers of ACE2-positive endothelial cells and significant changes in endothelial morphology, a finding consistent with a central role of endothelial cells in the vascular phase of COVID-19,” Ackermann and colleagues write. , Leader A HHS Small, non-randomized studies of a recombinant form of the endogenous IL-1 receptor antagonist, anakinra, have furnished sufficient encouragement to merit further definitive investigation.57,58 Anakinra blocks both IL-1α and IL-1β, and requires daily dosing. has no conflicts to declare. , Soehnlein O However, when stimulated by proinflammatory cytokines, pathogen-associated molecular patterns such as bacterial endotoxins, or neutrophil extracellular traps (NETs; see below), the endothelial cell can express and in turn exert tissue factor activity.12,13 Tissue factor activates the coagulation system by amplifying many-fold the enzymatic capacity of factors VII and X, triggering thrombin generation and clot formation.14 The endothelial cell also stores pre-formed von Willebrand factor (vWf) in intracellular granules called Weibel–Palade bodies. , de Heer G , Rao G , Sheikhzadeh-Eggers S , Yost CC This could trigger endothelial dysfunction, pyroptosis, and thrombosis, which are the vascular changes, commonly referred to as coronavirus disease 2019 (COVID-19) endotheliopathy.  |  The new coronavirus disease-2019 (COVID-19), which is spreading around the world and threatening people, is easily infecting a large number of people through airborne droplets; moreover, patients with hypertension, diabetes, obesity, and cardiovascular disease are more likely to experience severe conditions. Yet Covid-19 can affect … , Pan A As noted above, the normal endothelial cells also secrete PGI2 that, in addition to its antiaggregatory effects on platelets, potently vasodilates.18 This array of vasodilatory actions can also modulate moment-to-moment local blood flow in a paracrine fashion. , Shi H , Angelidis C , Tanner FC , Haverich A Angiotensin II is one of the strongest stimulants of Na + /H + exchanger (NHE).

ACE2 receptors are also expressed by endothelial cells. , Prudon B , Cannon JG , Katritsis D , Green C , Olie RH The endgame of COVID-19 usually involves a cytokine storm, a phlogistic phenomenon fed by well-understood positive feedback loops that govern cytokine production and overwhelm counter-regulatory mechanisms. , Fasol R , Narazaki M Under physiological circumstances, the endothelial gateway selectively regulates endothelial permeability and fosters vascular integrity. It is known that the angiotensin II level increases during infection of the virus. , Gargalianos P , Kappas A. Camici GG , Kluge S. Barnes BJ Lancet Haematol. The acute phase reactants include fibrinogen, the precursor of clot, and PAI-1, the major inhibitor of our endogenous fibrinolytic system. Patients with COVID-19 can have bowel abnormalities, ... “ACE2 expression is most abundant in lung alveolar epithelial cells, enterocytes of the small intestine, and vascular endothelium suggesting that small bowel and vasculature may be susceptible to SARS-CoV-2 infection,” they wrote. , Martinenghi S , Dupont S The complications of COVID-19 follow very closely the consequences of excessive cytokine actions on endothelial cells outlined above and depicted in Figure 1. However, we now recognize that SARS-CoV-2’s destructive actions range far and wide beyond the pulmonary parenchyma. , Koenen R , Libby P. Oemar BS , Frame D , Tschudi MR , Stang A, The endothelium serves as one of the main targets of the SARS-CoV-2 virus, and endothelial dysfunction largely determines the pathogenesis and clinical outcome in COVID-19 (Teuwen et al., 2020). , Vogler TO , Han M , Song X Integrins associated with the endothelial surface also participate in these adhesive interactions and furnish cognate ligands for the adhesion molecules.25 Once tightly bound to the endothelial surface, chemoattractant cytokines of various classes can beckon the bound cells to traverse the endothelial monolayer and enter tissues where they can combat invaders or contribute to tissue repair.26. They can express adhesion molecules that attract leucocytes and chemokines that direct their migration into the subendothelial space. The characteristic hyperinflammatory and procoagulatory state of COVID-19 implies a critical role of the endothelium, both as an effector contributing to inflammation and thrombosis, and as a target organ, whose dysfunction may contribute to poor outcome. , Luscinskas FW , van den Kerkhof D , Kotanidou A , Henskens YMC , Canetti D Induction of circulating interleukin-1 in rabbits, Interleukin-1 induces interleukin-1. While these functions participate in the moment-to-moment regulation of the circulation and coordinate many host defence mechanisms, they can also contribute to disease when their usually homeostatic and defensive functions over-reach and turn against the host. , Boffini N , Volpe M , Konkle BA , Wang D , Ceska M Several studies have linked COVID-19 with chilblains, or reddish-purple lesions on … Sloughing of endothelial cells uncovers the thrombogenic basement membrane. , Egeblad M In this study, we sought to investigate the status of vascular endothelial function in COVID-19 patients from a non-invasive approach. , Landoni G "When the virus damages the inside of the blood vessel and shreds the lining, that's like the ice after a hockey game," noted Dr. Li, a researcher and founder of the Angiogenesis Foundation. , Tomelleri A JAMA Netw Open, In-hospital use of statins is associated with a reduced risk of mortality among individuals with COVID-19, Interleukin-1 blockade with high-dose anakinra in patients with COVID-19, acute respiratory distress syndrome, and hyperinflammation: a retrospective cohort study, Anakinra for severe forms of COVID-19: a cohort study, Effective treatment of severe COVID-19 patients with tocilizumab, Tocilizumab for treatment of mechanically ventilated patients with COVID-19, SARS-CoV-2 and COVID-19: is interleukin-6 (IL-6) the ‘culprit lesion’ of ARDS onset? , Gao X Upon viral infection of ECs by severe acute respiratory syndrome coronarvirus 2 (SARS-CoV-2), ECs become activated and dysfunctional. The vascular endothelium: the cornerstone of organ dysfunction in severe SARS-CoV-2 infection. , Battista R , Reitsma PH Pre-clinical and autopsy studies have fueled the hypothesis that a dysregulated vascular endothelium might play a central role in the pathogenesis of ARDS and multi-organ failure in COVID-19. , Béa ML Therefore, it is reasonable to assume that ED contributes to COVID-19-associated vascular inflammation, particularly endotheliitis, in the lung, heart, and kidney, as well as COVID-19-associated coagulopathy, particularly pulmonary fibrinous microthrombi in the alveolar capillaries. , van Mourik M COVID-19 often causes thrombosis attacks during its infection. When subjected to normal laminar shear stress, the endothelium produces superoxide dismutase that scavenges the important reactive oxygen species O2–⁠.24 The endothelial cell can also express glutathione peroxidases that can mitigate oxidative stress.27 Likewise, haem oxygenase provides another mechanism by which the endothelial cell can resist local oxidative stress.28,29 In contrast, when stimulated by proinflammatory cytokines and other agonists, the endothelial cell can mobilize NADPH oxidases that generate superoxide anions, contributing to local oxidative stress.30 As with other beneficial properties, the endothelium can also contribute to disease through impaired antioxidant defences or actual generation of reactive oxygen species, as is the case in hypertension,31 hyperlipidaemia, and diabetes,32 among other cardiovascular conditions. , Weber A , Pogue JM. , Jeffery K , Li T 2020 Nov 21;9(11):3746. doi: 10.3390/jcm9113746.

While under usual circumstances the antiaggregatory arachidonate product prostacyclin (PGI2) dominates endothelial vasoactive prostanoid production, the endothelial cell can also produce thromboxane, a pro-platelet aggregatory and vasoconstrictor prostaglandin.16 The activated endothelial cell can also manufacture plasminogen activator inhibitor-1 (PAI-1), which can antagonize the endogenous fibrinolytic properties conferred upon the endothelial surface by the expression of uPA and tPA, as noted above. , Faust SN Under normal conditions, the endothelial cells promote tonic vasodilatation through the well-known mechanism of production of the vasodilatory gas nitric oxide from l-arginine via the activity of endothelial nitric oxide synthase.17 The endothelial cell can also elaborate diverse hyperpolarizing factors that promote relaxation of smooth muscle and hence dilatation of muscular arteries. The untrammelled production of proinflammatory cytokines contributes to a condition termed a cytokine storm (Figure 2). , Weber C All authors declare no conflicts of interest. Aggravation of endothelial dysfunction in COVID-19 may therefore impair organ perfusion and cause a procoagulatory state resulting in both macro- and microvascular thrombotic events. , Shen L , Tsioufis K He says that while COVID-19 can certainly cause breathing problems, he doesn’t think it’s just a lung disease. , Campochiaro C The Specter of Endothelial Injury in COVID-19 Studies signal that damage to the endothelium—cells that cover blood vessels like wallpaper—could underpin the thrombosis and inflammation induced by coronavirus infection. , Oltolini C , Leopold JA This unifying hypothesis can help to understand the complex pathophysiology of this current plague and may also help to inform our therapeutic approaches to combatting the consequences of SARS-CoV-2 infection.
