Gut microbiota and metabolites drive chronic sickle cell disease pain in mice Brandow et al. describe how the gut microbiome drives chronic sickle cell disease (SCD) pain. SCD guts contain excessive heme catabolites, fewer bacteria that metabolize bilirubin, and low levels of A...

1st paper from Sadler Lab is out!! Highlights: 1) A. muciniphila reverses sickle cell (SCD) pain, 2) fecal transplant from SCD mice induces pain via bilirubin-TRPM2 vagal signaling, 3) BilR+ bacteria less abundant in SCD patient poo, 4) RNAseq on HUMAN nodose ganglia! www.cell.com/cell-host-mi...
