Gut-Brain Axis and Gut Physiology
The enteric nervous system (ENS) is often called the second brain because of the high number of neurons along the GI tract. While this enables the gut to remarkably function independent of the rest of the body, there is a fair amount of communication between the gut and the brain. In particular, about ~80% of nerve fibers between the gut and brain are dedicated to send information to the brain.1 Recent studies involving the gut microbiome have demonstrated how this connection has the ability to impact the brain itself and may play a role in a number of central nervous system disorders.
ABNEL conducts research focusing on the intersection of the gut lumen (space containing food and microbes), epithelium (permeable barrier to the body), and ENS. This work aims to enable a better understanding of their impact on some CNS diseases like Parkinson’s disease. For more general information on the epithelium itself, please check out our recent review below led by Jessica.
