In most experimental human or rodent models, the anti-inflammatory actions of E2 on innate immunity includes the suppression of the production of proinflammatory cytokines, for example, IL-6, IL-1β, and TNF-α, by monocytes and macrophages (a major factor in the COVID-19 cytokine storm) and a strong inhibition of CCL2, thus preventing innate immune cells migration into inflamed areas, particularly neutrophils and monocytes. Taken together, these findings suggest that E2 and related SERMs have 2 potential protective mechanisms of action against SARS-CoV-mediated pneumonias in mice: 1) an estrogen-dependent decrease in the deadly innate immune response and cytokine storm in the lungs, thus preventing respiratory failure, and 2) specific to SERMs, an off-target direct inhibition of SARS-CoV replication and cytopathic effects. ./cache/cord-327086-u3l8nr73.txt ./txt/cord-327086-u3l8nr73.txt
