Vagotomy and insights into the microbiota-gut-brain axis

Liu Y, Forsythe P (2021) Vagotomy and insights into the microbiota-gut-brain axis. Neurosci Res 168:20-27. doi: 10.1016/j.neures.2021.04.001

Objective: To review the use of vagotomy as a tool to explore the role of the vagus nerve in gut to brain signaling.

Summary: This review article is a summary of the knowledge gained from vagotomy, a surgical procedure that involves removing part of the vagus nerve. The article discusses using CCK-SAP to specifically ablate afferent vagal nerves in the gastrointestinal tract.

Usage: The article references a study by Diepenbroek et al. that used CCK-SAP in the following dosages: In vitro: each well was treated with a different dose of saporin conjugates (0, 2.4, 24, or 240 ng) for 24 h. In vivo: An equal volume (rat: 1 µl; mouse: 0.5 µl) of CCK-SAP (250 ng/µl) or Saporin (250 ng/µl) was injected at two sites rostral and caudal to the laryngeal nerve branch.
