Polish researcher: vast computer compound search indicates Dexamethasone Vitamin D Vitamin E may help calm or prevent Cytokine Storm in worst covid-19
Sample quote
Co-author Artur Wnorowski, Ph.D., Department of Biopharmacy, Faculty of Pharmacy, Medical University in Lublin, Poland, undertook an intriguing challenge that yielded surprising results. "I analyzed major databases to identify chemicals that downregulate both AhR and IDO1, or AhR gene expression. I selected 596 molecules and an in-depth analysis of 23,526 experiments involving these molecules identified either a single molecule that repeatedly reduced AhR and IDO1 or AhR gene expression in human cells."
The molecules were dexamethasone for AhR and IDO1, and calcitriol, the active form of vitamin D, which is also known to inhibit the spread of other viral infections, for the AhR gene. Likewise, tocopherol, a form of Vitamin E, might downregulate IDO1 and is known to play a positive role in response to viral infections and inflammation in aging.
The authors call for epidemiological studies and prospective trials to determine if calcitriol and tocopherol supplementation should be recommended for the prevention of SARS-CoV-2 infections.
"Our concept is based on 40 years of research experience with the metabolism of tryptophan. Activation of IDO1 in immune cells leads to release of kynurenine, a tryptophan metabolite, activates AhR. IDO1 was the clue that brought us to the AhR-IDO1 axis concept and exposed the role that AhR may play in the pathogenesis of COVID-19," says Dr. Waldemar Turski.
