Project Description
The intestine harbors a complex microbial community. The microorganisms residing in the intestinal lumen have a significant impact on brain function and behavior. However, the cellular and molecular mechanisms by which gut microbiota modify brain function are unclear. Our lab’s previous research revealed that a group of specialized sensory cells called enteroendocrine cells (EECs) in the intestinal epithelium is able to sense gut bacteria and directly transmit the bacterial information to the vagus nerve, the primary sensory neurons that connect the gut and brain. Gut bacteria can secrete certain metabolites to activate or inhibit the EEC-vagal pathway to change brain activity and function. The Ye lab uses the zebrafish animal model, gnotobiotic technology, and in vivo microscopic imaging to dissect the molecular mechanisms by which gut bacteria talk to the brain. We use genetic recombination, transposase-mediated insertion, and CRISPR-cas9 genetic editing in both bacteria and zebrafish to dissect the signaling pathway that underlies bacterial and brain communication.
