RNA Sensing by Gut Piezo1 Is Essential for Systemic Serotonin Synthesis.

abstract：:Motor neurons stimulate their postsynaptic muscle targets to synthesize neurotransmitter receptors. Polypeptide signaling molecules may mediate this inductive interaction. Here we report the purification of ARIA, a protein that stimulates the synthesis of muscle acetylcholine receptors, and the isolation of ARIA cDNA....
