COVID-19 and Endothelial Cell Dysfunction Initial SARS-CoV-2 infection occurs within the lung epithelia, whereby serine proteases, most notably transmembrane protease serine 2 (TMPRSS2), cathepsin B, and cathepsin L1, prime the SARS-CoV-2 spike glycoprotein, which is followed by ACE2-mediated viral entry ( 29 ). The glycocalyx consists of highly sulfated proteoglycans with glycosaminoglycan side chains. Vasculopathy in COVID-19. The intact barrier structure of sulfated glycocalyx of the endothelium could repel SARS-CoV-2. All these reported effects could justify the curative effects of tocilizumab on COVID-19 [138]. 2021;58:457587.

EClinicalMedicine. However, pre-treatment of ECs with losartan (belonging to ARB) and lisinopril (belonging to ACEI), fail to affect the susceptibility of hEC to SARS-CoV-2 infection [131]. Protein Cell. ET. Management requires the immediate reduction of core temperature. Furthermore, SARS-CoV-2 infection leads to decreased expression of tight junction protein (ZO-1, occluding and claudin5) and blood brain barrier permeability [75]. In addition, reduced flow-mediated dilation (FMD, an easily obtainable method to assess endothelial dysfunction) was observed in COVID-19 patients, thus offering additional markers to serve as the proxy of endothelial cell activation [108]. TCM could significantly relieve clinical symptoms, reduce disease severity, reduce the need for mechanical ventilation, shortening the duration of hospitalization, accelerate symptom recovery, and ultimately reduce mortality rate [161,162,163,164]. In this regard, ACE2 downregulation and the disrupted balance between the RAAS and ACE2/Ang-(17)/MAS axis may also contribute to multiple organ injury in COVID-19 [87, 130].

Studies in the past two years altogether provide important mechanistic insights into the pathogenesis of COVID-19 and yield promising new therapeutic targets (Fig. CAS PubMed Central Therefore, IL-6 trans-signaling represents the mechanistic link between the coagulopathy/endotheliopathy and COVID-19 associated liver injury [35]. Lowenstein CJ, Solomon SD. According to the American-European Consensus Conference on acute respiratory distress syndrome (ARDS), the ARDS is the most severe form of the acute lung injury [17] as well as ongoing COVID-19 associated lethality [18]. SARS-CoV-2 spike protein S1-mediated endothelial injury and pro-inflammatory state is amplified by dihydrotestosterone and prevented by mineralocorticoid antagonism. ECs are also capable of counteracting ROS, by increasing superoxide dismutase (SOD), catalase, glutathione peroxidase, and NRF2-dependent heme-oxygenase 1 expression [2]. After virus infection, ensuing cytokine storm occurs in severe COVID-19 patients, particularly the elevated secretion of pro-inflammatory cytokine interleukin 6 (IL-6).

Taken together, the concerted actions of above factors lead to dysfunctional status of the vascular endothelium (endothelial dysfunction) (Fig. Targeting inflammation and cytokine storm in COVID-19. 2020;11:605908. 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. It is well-known that IL-1 induces the expression of itself and other pro-inflammatory and pro-adhesive molecules, such as TNF-, leading to the amplification of cytokine storm. Recently, miR-98-5p was identified as a negative regulator of TMPRSS2 gene transcription in human lung and umbilical vein ECs [98].

It remains to be investigated whether other mechanisms that are more closely related to COVID-19, such as long non-coding RNA, circular RNA, RNA methylation, microbiota and metabolites, are involved in triggering endothelial dysfunction following SARS-COV-2 infection. Severe COVID-19-induced cytokine storm (such as IL-6, IL-1, TNF-, MCP-1, etc) is a good predictor ofthe severity of COVID-19, which also aggravates multi-organ injury by propagating the vicious cycle of ECs damage, inflammation and thrombosis [93]. 2021;163:15362. Intern Emerg Med. The fight against coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 infection is still raging. Mounting evidence suggests that SARS-CoV-2 infection leads to multiple instances of endothelial dysfunction, including reduced nitric oxide (NO) bioavailability, oxidative stress, endothelial injury, glycocalyx/barrier disruption, hyperpermeability, inflammation/leukocyte adhesion, senescence, endothelial-to-mesenchymal transition (EndoMT), hypercoagulability, thrombosis and many others.

Front Immunol. Treatment of virus-infected human lung microvascular endothelial cells (HMVECs) with diminazene aceturate (an ACE2 agonist) reverses SARS-CoV-2 infection-induced hyperpermeability, indicating the possibility that ACE2 agonism indeed stabilizes endothelial barrier integrity without affecting viral uptake into ECs [23]. Front Med. The Erectile Dysfunction Drugs report tracks competitive progresses, strategies, mergers and acquisitions and new product development. 2021;3:e690e7. More recently, it is reported that thrombomodulin level was associated with augmented infiltration of immune cells in autopsy lung tissues [79], explaining the existence of thromboembolism in COVID-19 patients. COVID-19 can present with multiple manifestations arising from endothelial dysfunction/endotheliopathy as below (Fig. Milani GP, Macchi M, Guz-Mark A. Vitamin C in the treatment of COVID-19. SARS-CoV-2 infection primarily affects the pulmonary system, but accumulating evidence suggests that it also affects the pan-vasculature in the extrapulmonary systems by directly (via virus infection) or indirectly (via cytokine storm), causing endothelial dysfunction (endotheliitis, endothelialitis and endotheliopathy) and multi-organ injury. Consistent with this notion, elevated level of C3a in severe COVID-19 patients induced the activation of CD16+ cytotoxic T cells which promotes endothelial injury and the release of monocyte chemoattractant proteins as well as neutrophil activation [96]. Prevalence of Chemosensory Dysfunction in COVID-19 Patients: A The most common clinical presentation of severe COVID-19 is acute respiratory failure consistent with the acute respiratory distress syndrome. Arch Med Res. Microcirculation (N. Y, N. Y: 1994). In addition to the above drugs discussed, there are several other reports showing that serine protease inhibitors (camostat mesylate), KLF2 activators [120], RIPK3 inhibitors [166], spironolactone [77], glycocalyx repairing drugs [67], purified glycosaminoglycan mixture sulodexide [167], CCR5 blockers (Maraviroc), anti-VEGF (bevacizumab [168]), adrecizumab [169], mesenchymal stem cell therapy [170], estrogen [171], melatonin [172] and NO donor [173] could also be beneficial (Fig. In a single-center observational study, 82% of critically ill COVID-19 patients have significantly lower plasma level of vitamin C [154].
