New paper on the non-specific effects of BCG vaccine: Priming monocytes with BCG induces glycolysis and lactate production. This results in increased inflammatory cytokine release upon restimulation with LPS and is linked to p300-mediated histone lactylation that can persist over

#WeekendRead #InterferonsFriendsOrFoes?! @RuthFranklinLab @RMedzhitov &co show @ScienceMagazine that macrophage-derived oncostatin M overcomes type I IFN detrimental effects during influenza lung infections by driving AT-II epithelial cell proliferation!
science.org
Tissue repair programs must function alongside antiviral immunity to restore the lung epithelial barrier following infection. We found that macrophage-derived oncostatin M (OSM) counteracted the...

In a new paper, we hypothesize that intradermal administration of BCG to the human newborn leads to low-grade bacteremia and that this systemic dissemination improves protection against tuberculosis. The hypothesis is based on supporting observations including animal and human
