FXR inhibition may protect from SARS-CoV-2 infection by reducing ACE2

This manuscript (1) reports on extensive and compelling experimental evidence and translational data from retrospective review of clinical registries, which show that pharmacological inhibition of the farnesoid X receptor (FXR) could be a novel intervention for the prevention or treatment of COVID-19. The in vitro and in vivo studies show that FXR antagonism reduces ACE2 expression, which subsequently reduces SARS-CoV-2 infection in the lung, liver and gastrointestinal tract.
