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...
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...

Enteric neuronal Piezo1 maintains mechanical and immunological homeostasis by sensing force
Expression and functional analysis define how Piezo1-dependent cholinergic responses by enteric neurons directly sense luminal pressure to orchestrate digestion and inflammation in mice.

Interoception and gut–brain communication
The brain senses changes to the internal state of the body, eliciting responses that maintain homeostasis. Alhadeff and Yapici provide an overview of this process, termed interoception, with a particu...
