SARS-CoV2-mediated suppression of NRF2-signaling reveals potent | ResearchBunny

Abstract

This study demonstrates that the NRF2 antioxidant gene expression pathway is suppressed in COVID-19 patients. NRF2 agonists, 4-octyl-itaconate (4-OI) and dimethyl fumarate (DMF), inhibit SARS-CoV-2 replication across various cell lines. This antiviral effect extends to other viruses like HSV-1, HSV-2, Vaccinia, and Zika, through a type I interferon (IFN)-independent mechanism. 4-OI and DMF also limit inflammatory responses to SARS-CoV-2 infection. Therefore, NRF2 agonists show promise as broad-spectrum antiviral and anti-inflammatory agents, with DMF potentially repurposed for COVID-19 treatment.
