Likewise, in a retrospective study involving ninety-nine patients with COVID-19, the degree of endothelial damage was correlated with disease severity in COVID-19, suggesting that number of CEC is a good predictor of disease severity [116]. 2020;11:605908. 2021;8:687783. 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]. Wu D, Lee TH, Huang RT, D Guzy R, Schoettler N, Adegunsoye A, et al. 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]. 2020;11:70722. Physiological functions of the endothelium include fine control of vascular tone, tissue hemostasis, barrier integrity, inflammation, oxidative stress, vascular permeability, and structural and functional integrity [4]. As well, nAChR activators through interaction with diverse signaling pathways can reduce the risk of inflammatory disorders in 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. 2020;7:629413.

Article Medicine (Baltimore). 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].

The disrupted glycocalyx structure leads to hyperinflammatory response and oxidative stress, which leads to increased susceptibility to SARS-CoV-2 infection [67]. These findings suggest that spike protein interactions with ECs contribute to inflammation, thrombosis, and the severity of COVID-19 and could offer novel mechanistic insights into SARS-CoV-2 induced vascular leakage and the development of targeted therapies [59]. In addition, mtDNA release also increased vascular reactivity to ET1[94]. Plasma level of resistin is increased in COVID-19 patients and associated with disease severity as well as the expression of inflammatory cytokines (IL-6, IL-8 and MCP-1) and adhesion molecules (ICAM1 and VCAM1) [80]. 2020;116:e195e7.

ACE2 is a key regulator of RAAS by catalyzing the production of Ang-(17) from AngII, and the Ang-(17) can act on MAS receptor to combat the harmful effects caused by activation of RAAS[87, 130]. Clinical and pathological investigation of patients with severe COVID-19.
