Similar effects have been demonstrated in several mouse studies with the ability to reduce virus titers in lung tissues and modulation of antiviral and pro-inflammatory gene expression before and after viral infection. The upregulation of IFN response seems to prime cells for better resistance against virus infection as probiotics were shown effective in inhibiting the replication of various respiratory viruses, including influenza viruses and RSV. Similar effects have been demonstrated in mice with the ability of the probiotics to reduce virus titers in lung tissues and to modulate antiviral and pro-inflammatory gene expression before and after viral infection.
