COVID-19 is associated with pervasive ECs injury, increased capillary permeability, infiltration of inflammatory cells into perivascular tissues, interstitial edema and fluid retention in alveolar spaces [19]. IL-6 directly impacts vascular ECs by promoting the production of numerous cytokines/chemokines/adhesion molecules essential for promoting leukocyte adhesion, vascular leakage and activating the coagulation cascade [136]. Kim WY, Kweon OJ, Cha MJ, Baek MS, Choi SH. Pine AB, Meizlish ML, Goshua G, Chang CH, Zhang H, Bishai J, et al. Moreover, supernatant from virus-infected cells can trigger neutrophil extracellular trap formation and platelet activation [88]. Cytokine storm. The authors declare no competing interests.

In addition, due to the fact that trained immunity in ECs is an important mechanism in propagating endothelial response to inflammatory/immune insults after prior exposure to microbial stimuli [100], detailed mechanisms of epigenetic memory in transducing the SARS-COV-2 infection-induced immune signal needs further studies. 2017BT01S131), Hefei Comprehensive National Science Center (Grant No. 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. Besides directly infected by SARS-CoV-2, the ECs also undergo injury by systemic inflammation caused by over-activation of innate immune response, referring to cytokine storm [91, 92].

Direct or indirect mechanisms are operating to collectively indicate the alterations in vascular homeostasis in COVID-19 [54]. Although current pharmacotherapies against acute and post-acute COVID-19 mainly centered on blocking viral replication and limiting inflammation/inflammasome activation, it is likely that novel therapeutic approaches targeting endothelial dysfunction could represent a promising strategy to cardiovascular sequelae in COVID-19 convalescent patients [6] in light of elevated circulating level of biomarker soluble P-selectin in COVID-19 convalescent donors compared to healthy controls [175].

CAS 2020;32:53747. 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). SARS-CoV-2 infection alters the balance of endothelial protective molecules and endothelial damaging molecules, leading to endothelial dysfunction. Recent randomized clinical trials revealed that treatment with fluvoxamine (a selective serotonin reuptake inhibitors, SSRI) reduced the need for COVID-19 hospitalization, reduced mortality and improved outcome over 15 days [148,149,150]. Lee KCH, Sewa DW, Phua GC.
