By doing so, anakinra significantly increased the survival rate of infected mice [140]. Antiviral therapies and effective vaccination reduce viral load and could potentially offer endothelial protection in perivascular spaces [19]. Heparin prevents in vitro glycocalyx shedding induced by plasma from COVID-19 patients. Would you like email updates of new search results? as well as ROS and RNS by inducing mitochondrial dysfunction and production of proinflammatory cytokines ( 15 ). J Hepatol. 2017;12:e0186116. Thus, the endothelium is regarded as the Achilles heel in COVID-19 patients [8]. The relationship between mechanisms and biomarkers of endothelial dysfunction in COVID-19 is provided in Fig. Acute brain dysfunction is highly prevalent in COVID-19 patients. Elevated level of VEGF in senescent ECs and COVID-19 patients are potent trigger of increased angiogenesis in patient tissues, underlying the clinical utility of anti-VEGF treatment for COVID-19 patients [86, 87]. 2022;11:1972. JCI insight. 2020;73:123140. 2021;2021:8671713. This article reviews what is known about the effects of severe acute respiratory syndrome . SARS-CoV-2 spike protein S1-mediated endothelial injury and pro-inflammatory state is amplified by dihydrotestosterone and prevented by mineralocorticoid antagonism. 2021;10:e69314. J Neuroinflammation. Gladka MM, Maack C. The endothelium as Achilles heel in COVID-19 patients. 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]. Atherosclerosis. In the meantime, to ensure continued support, we are displaying the site without styles The infected cell releases danger signals leading to multiple aspects of endothelial dysfunction, which finally leads to impaired vascular activity and multi-organ injury. It represents a potential biomarker for monitoring disease progression in COVID-19 patients [112]. SARS-CoV-2 Spike triggers barrier dysfunction and vascular leak via integrins and TGF- signaling. Possible involvement of Syndecan-1 in the state of COVID-19 related to endothelial injury.
