Markers of endothelial cell activation are associated with the severity of pulmonary disease in COVID-19. 2021;95:e0139621. 2020;116:166687. Thus, hyperinflammation and inflammasome activation associated with SARS-CoV-2 infection will lead to endothelial cell injury and death (such as pyroptosis). Direct activation of endothelial cells by SARS-CoV-2 nucleocapsid protein is blocked by simvastatin. The net consequence is the extravasation of inflammatory and immune cell infiltrations [74]. L-arginine improves endothelial dysfunction by being the substrate of NO generation in endothelial cells. Antiviral therapies and effective vaccination reduce viral load and could potentially offer endothelial protection in perivascular spaces [19]. CD209L/L-SIGN and CD209/DC-SIGN act as receptors for SARS-CoV-2. The thermoregulation system includes the hypothalamus in the brain, as well as the sweat. SARS-CoV-2 and COVID-19: The most important research questions. SGLT2 inhibitors can reduce the composite endpoint of cardiovascular death and HF hospitalizations in heart failure patients either with reduced ejection fraction or preserved ejection fraction.

CAS Based on these protective effects, statin may be used as an adjunctive therapy to mitigate endothelial dysfunction accompanying SARS-CoV-2 infection. A new study by investigators from the Smidt Heart Institute at Cedars-Sinai suggests long COVID-19 might be caused by a dysfunction of .

PubMed 2021;348:109657. The fight against coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 infection is still raging. Direct SARS-CoV-2 infection or indirect effect arising from SARS-CoV-2 infection leads to endothelial dysfunction in pan-vasculature, which results in the development of multi-organ tissue injury. S protein treatment of HAECs leads to increased secretion of inflammatory molecules (IL-6, MCP-1 and IL-18) and PAI-1, which can be attenuated by minerocorticoid receptor antagonists [56]. 2022;23:6196. Noris M, Benigni A, Remuzzi G. The case of complement activation in COVID-19 multiorgan impact. 2021;40:101125. In a randomized clinical trial, L-arginine add-on therapy significantly reduces the length of hospitalization in severe COVID-19 patients and reduces the need of respiratory support, with no serious adverse events [147]. Injury to the endothelial glycocalyx in critically Ill patients with COVID-19. COVID-19 and Acute Coronary Syndromes: From Pathophysiology to Clinical 8600 Rockville Pike Nagashima S, Mendes MC, Camargo Martins AP, Borges NH, Godoy TM, Miggiolaro A, et al. Both SARS-CoV and SARS-CoV-2 utilizes ACE2 and membrane-bound co-factors for virus entry. Qian Y, Lei T, Patel PS, Lee CH, Monaghan-Nichols P, Xin HB, et al. The disrupted glycocalyx structure leads to hyperinflammatory response and oxidative stress, which leads to increased susceptibility to SARS-CoV-2 infection [67]. Sansone A, Jannini EA. 2021;9:1438. From a study cohort (consisting of 76% male and 24% female individuals), there was at least one abnormality of diaphragm muscle function on structure visualized by ultrasound in 80% of cases. EndoMT, defined as the loss of endothelial markers/characteristics (CD31, VE-cadherin and Tie2) and gaining of mesenchymal cell markers (FSP-1, -SMA and vimentin), is central to COVID-19 induced lung fibrosis and pulmonary artery hypertension [72, 73]. 2022;216:1204. In COVID-19 patients, heart failure and myocardial injury are frequent complications, underscoring the clinical utility of SGLT2 inhibitors [128]. In addition to the spike protein, nucleocapsid protein of SARS-CoV-2 can also promotes endothelial activation via TLR2/NF-B and MAPK signaling pathways. Till now, several TCM have shown good therapeutic effects in COVID-19, such as Lianhua Qingwen, Xuebijing Injection, Shuanghuanglian, Jinyinhua and Qingfei Paidu Decoction [161,162,163,164].

Pine AB, Meizlish ML, Goshua G, Chang CH, Zhang H, Bishai J, et al. 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). Thermoregulatory dysfunction is defined as significant loss of a person's capacity to control body temperature, and the medical conditions which result in the person's health and bodily function being seriously affected when exposed to extremes of environmental temperatures. Okada H, Yoshida S, Hara A, Ogura S, Tomita H. Vascular endothelial injury exacerbates coronavirus disease 2019: The role of endothelial glycocalyx protection. In addition, we need to screen for atherosclerotic plaque formation in COVID-19 survivors, as there are no actual clinical data providing the causal relationship between COVID-19 and atherosclerosis. Further outstanding questions and research directions in the realm of endothelial dysfunction and COVID-19 include the following: The development of assays of assessing endothelial function in long COVID-19 patients and convalescents, such as brachial artery flow-mediated dilation (FMD) and arterial stiffness [carotid-femoral pulse wave velocity (cfPWV)]; This aspect is important considering the recent observation showing the decreased FMD in patients with COVID-19 stemming from expression of inflammatory cytokines/chemokines [176]; Cellular and animal models of evaluating endothelial dysfunction in COVID-19 to accelerate drug discovery; The therapeutic potential of specialized pro-resolving lipid mediators, such as resolvin D1, resolvin E1, aspirin-triggered resolvin D1 in resolving cytokine storm induced inflammatory responses can be pursued; The identification of alternative receptors for SARS-CoV-2 infection into different vascular beds beyond known ones (such as ACE2, AXL and L-SIGN) remain to be identified; Drug repurposing or high-throughput drug screening to identify new drugs targeting endothelial dysfunction in COVID-19; The role of epigenetic modification arising from DNA methylation and histone modification and long-lasting epigenetic memory effects caused by SARS-CoV2 infection in long COVID (postacute COVID-19 syndrome) remain to be evaluated [7]; Metabolic disturbance has been shown to be associated with the pathogenesis of COVID-19 [177].
