Xu S, Liu Y, Ding Y, Luo S, Zheng X, Wu X, et al. These evidences suggest that inhibition of complement pathway could be an effective strategy to manage endothelial injury/endotheliitis accompanying COVID-19 [97]. We also present emerging therapeutic agents and therapeutic targets which are directed at reducing the consequence of endothelial dysfunction/endotheliitis/endotheliopathy.

Mortality risk among patients with COVID-19 prescribed selective serotonin reuptake inhibitor antidepressants. Intriguingly, the main coronary arteries have no detectable expression of ACE2, suggesting the occurrence of COVID-19-induced endotheliitis in small vessel like capillaries; however, the culprit in the main coronaries are largely dependent on indirect mechanism arising from SARS-CoV-2 infection [47]. It is reported that COVID-19-patients had higher number of CECs than COVID-19-free subjects. EBioMedicine. Possible involvement of Syndecan-1 in the state of COVID-19 related to endothelial injury.

Tocilizumab improves oxidative stress and endothelial glycocalyx: A mechanism that may explain the effects of biological treatment on COVID-19. The existence of cytokine storm could trigger vascular leakage, endothelial permeability in particular. It is appreciated that SARS-CoV-2 infection can trigger systemic vascular injury through binding to ACE2. It has been increasingly appreciated that COVID-19 is not only an infectious disease involving the lung; but also, a vascular disease affecting extrapulmonary organs [174]. Mitochondria is an important organelle that regulates antioxidant/redox signaling, by fine-tuning mitochondria-derived reactive oxygen species (mtROS) production.

EClinicalMedicine. Under physiological conditions, ECs undergoing apoptotic process are released into circulating blood. Keywords: The decrease of NO bioavailability occurs partially because of a decrease in eNOS-derived NO production and enormous production of reactive oxygen species (ROS), which inactivates eNOS and causes eNOS uncoupling. In vivo, SARS-CoV-2-infected K18 mice develop severe COVID-19 and endothelial dysfunction in pulmonary vessels suggested by VCAM-1 and ICAM-1 upregulation and VE-cadherin downregulation [78]. Forensic Sci Med Pathol. 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]. XDB38010100). Dexamethasone treated group exhibited a significantly decreased levels of various markers associated with endothelial dysfunction, including Ang-2, ICAM-1, and sRAGE [135]. In addition, C-type lectin receptor L-SIGN, a receptor highly expressed on LSECs and lymphatic endothelial cells, was identified as the receptor for SARS-CoV-2 infection and may contribute to endotheliopathy in the liver [33].

Glycocalyx layer regulates vascular barrier integrity, leukocyte adhesion, mechanosensing, mechanotransduction, anti-inflammatory and anti-thrombotic functions [109]. Liu Z, Ma X, Ilyas I, Zheng X, Luo S, Little PJ, et al. COVID-19 is an endothelial disease in which endothelial dysfunction played a major role. 2022;21:e13646. Therefore, IL-6 trans-signaling represents the mechanistic link between the coagulopathy/endotheliopathy and COVID-19 associated liver injury [35]. Nutrients.

Heat exhaustion; Heat stroke; Hypohidrosis; Hypothermia; Rewarming; Small fiber neuropathy; Thermoregulation. SARS-CoV-2 targets the pulmonary system, as well as the extrapulmonary system [2]. Thus, metformin could be beneficial in reducing the mortality and composite outcomes in COVID-19 patients with T2DM [125]. Rotoli BM, Barilli A, Visigalli R, Ferrari F, DallAsta V.

Pathogenesis of COVID-19 described through the lens of an undersulfated and degraded epithelial and endothelial glycocalyx. In this regard, miR-24-3p has recently been identified as an essential regulator of Neuropilin-1 gene transcription, thereby maintaining barrier integrity via suppressing VEGF-induced endothelial leakage in human brain ECs [99]. 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. 2022;10:812. de Rooij L, Becker LM, Carmeliet P.

Further studies revealed that tocilizumab inhibited the expression of senescence markers (p21 and p16), ROS generation as well as endothelial adhesion molecule mediated leukocyte adhesion [90]. Because each symptom can be traced to the autonomic nervous system and its dysfunction, a platform for investigation is clear. Vitamin C is an essential, safe and inexpensive nutrient [152] that has anti-oxidant, anti-infectious, anti-inflammatory, anti-thrombotic and immune-modulatory effects [153]. Res Square. SARS-CoV-2 spike promotes inflammation and apoptosis through autophagy by ROS-suppressed PI3K/AKT/mTOR signaling. However, blockade of TLR9 significantly mitigated SARS-CoV-2-induced IL-6 release and reversed SARS-CoV-2-induced eNOS downregulation. Caccuri F, Bugatti A, Zani A, De Palma A, Di Silvestre D, Manocha E, et al. Similarly, in human aortic ECs (HAECs) treated with recombinant SARS-COV-2 S protein, increased secretion of inflammatory molecules and marker of thrombosis (IL-6, IL-18 and MCP-1 and PAI-1) were observed [56].
