Highlights Meta-analysis of 11,115 gut metagenomes links uncultured species to human health Healthy individuals show enrichment and greater diversity of uncultured bacteria The genus CAG-170 contains uncultured taxa with the strongest health signatures CAG-170 is ecologically important in healthy populations Summary The human gut microbiome is important for host health, yet over 60% of gut species remain uncultured and inaccessible to experimental manipulation. Here, we analyze 11,115 human...

Highlights Severe IAV infection imparts a long-lasting decline in cardiac function Atypical GMP-independent CD319+ pro-DC3s transport infectious IAV to cardiomyocytes Direct IFN-I signaling on cardiomyocytes drives cardiac dysfunction mod-mRNA delivery of dominant-negative IFNAR1 on cardiomyocytes ameliorates damage Summary Abundant evidence has correlated influenza infection with cardiovascular disease, yet mechanisms linking infection with the heart remain poorly understood. Here, we show...
