Neuroplastic changes in the enteric nervous system (ENS) occur during disease and aging. Studying ENS plasticity offers insights into gut disorders and potential new treatments.

Area of Science:

Neuroscience
Gastroenterology
Cell Biology

Background:

Enteric nervous system (ENS) plasticity is observed in development, aging, and diseases like inflammatory bowel disease (IBD) and Parkinson's disease.
Understanding ENS neuroplasticity is crucial for elucidating disease pathophysiology and developing novel therapeutic strategies.
This review focuses on ENS neuronal plasticity induced by gastrointestinal inflammation in IBD and inflammatory enteric neuropathies.

Purpose of the Study:

To review the major features of neuroplasticity within the enteric nervous system during inflammation.
To explore the mechanisms underlying ENS plasticity, including the role of neurotrophins and enteric glia.
To highlight the potential of understanding ENS plasticity for developing new therapeutic options.

Main Methods:

Review of existing literature on ENS plasticity in the context of gastrointestinal inflammation.
Analysis of structural and functional changes in the ENS, including nerve rearrangement, cell loss, neurotransmitter alterations, and receptor modulation.
Examination of gastrointestinal dysfunction, sensory-motor and secretory impairments, and remote neuroplastic changes.

Main Results:

Inflammation triggers structural ENS abnormalities like nerve hypertrophy, hyperplasia, and ganglion cell loss.
Neurotransmitter synthesis, content, release, and receptor systems are altered during ENS inflammation.
Gastrointestinal dysfunction, including sensory-motor and secretory impairments, characterizes ENS plasticity in disease.
Neuroplastic changes can occur in distant gut segments and are influenced by neurotrophins and enteric glia.

Conclusions:

ENS plasticity is a significant factor in the pathophysiology of inflammatory bowel disease and inflammatory enteric neuropathies.
Understanding these neuroplastic changes is key to developing targeted pharmacological interventions.
Further research into neurotrophins and enteric glia may unlock new therapeutic avenues for gut motility disorders.
