In addition to various pharmacological agents, many natural products have been examined for their ability to affect ACE2. Modulation of ACE2 expression has been proposed to assist in ameliorating the negative effects of SARS-CoV-2 infection. Based on this perspective, ACE1 inhibition and angiotensin receptor blockers would be beneficial for COVID-19 patients, as has been reported for SARS-CoV. When applied to the circulatory system, it has been suggested that this imbalance plays a major role in the injury caused by SARS-CoV-2 in different organ systems, due to increased AngII signaling. An imbalance in ACE1/ACE2 caused by infection would result in enhanced AngII production, promoting the progression of thrombotic and inflammatory processes and increased vasoconstriction. ACE1 converts angiotensin I to angiotensin II (AngII), a potent vasoconstrictor, whereas ACE2 hydrolyses AngII to angiotensin-(1–7), a vasodilator. Based on these data, as well as evidence that ACE1 levels are unchanged by infection, it is likely that SARS-CoV-2 infection causes an imbalance in the relative levels of angiotensin-converting enzyme 1 (ACE1) and 2 (ACE2). Consequently, identifying novel therapies that can stabilize endothelial function may provide alternative strategies to ameliorate the poor clinical outcomes associated with COVID-19 infection.īoth the presence of ACE2 in endothelial cell membranes and its catalytic activity are reduced by the shedding of ACE2 in response to the cellular entry of SARS-CoV viruses. Cytokine storms and associated endothelitis (inflammation of the endothelium) may be critical factors in the processes that promote organ failure, and subsequent COVID-19 morbidity and mortality. SARS-CoV-2 infection can contribute to endothelial dysfunction by triggering inflammatory and immune responses that cause a cytokine storm, hypoxia, and elevated oxidative stress. Endothelial dysfunction is one of the common underlying phenomena in diseases that elevate COVID-19-risk, such as CVD. The mortality and severity of COVID-19 is significantly higher in patients with pre-existing health conditions, such as cardiovascular disease (CVD), hypertension, and diabetes. Besides being a respiratory virus, SARS-CoV-2 is increasingly recognized as a vascular pathogen causing severe cardiovascular complications and renal dysfunction. The current COVID-19 pandemic, caused by the SARS-CoV-2 virus, has claimed millions of lives. Our findings warrant further evaluation of long-chain n3-PUFA supplements as a novel option for restricting SARS-CoV-2 infectivity in the general population. ![]() These results strongly suggest that DHA treatment may reduce the ability of SARS-CoV-2 to infect cells via a mechanism involving a decrease in the absolute level of ACE2 protein as well as its glycosylation. However, treatment of HEK293 cells with 80 and 125 µM DHA for 16 h inhibited the entry of the SARS-CoV-2 pseudovirus. Dietary supplementation with either DHA or ALA had no effect on plasma soluble ACE2 levels in humans. Docosahexaenoic acid (DHA), and in some cases eicosapentaenoic acid (EPA), but not α-linoleic acid (ALA), reduced both ACE1 and ACE2 (non-glycosylated p100 and glycosylated p130 forms) in the heart, aorta, and kidneys of obese rats, as well as in human EA.hy926 endothelial and HEK293 kidney cells. The ability of n3-PUFA to affect the entry of the SARS-CoV-2 pseudovirus into cells was also tested. In this study, the effects of omega-3 polyunsaturated fatty acids (n3-PUFA) on the protein levels of ACE1 and ACE2 in rodent tissues, human endothelial and kidney cell lines, and human plasma were examined. So far, reports describing conditions capable of altering ACE2 protein levels, especially via dietary components, are limited. Even though lower ACE2 levels may be beneficial in SARS-CoV-2 infectivity, maintaining the ACE1/ACE2 balance is also crucial for cardiovascular health. This review focuses on two majorĭemographic groups (smokers and nonsmokers) and evaluates the most recent data (earlyĢ017 to mid 2019) regarding the potential health effects of e-cigarettes.Angiotensin-converting enzyme 2 (ACE2) is a target of interest for both COVID-19 and cardiovascular disease management. Many nonsmokers, including youth, are using them. ![]() Although e-cigarettesĪre marketed as a smoking cessation tool by some manufacturers, the reality is that ![]() ![]() It necessary to regularly review and summarize available studies. Furthermore, e-cigarettes continue to evolve at a rapid rate, making One proposed solution to the problem has been e-cigarettes however, because theyĪre a relatively new product in the market, little is known about their potential Smoking continues to be a burden to economies and health-care systems across the world.
