What is Monogastric Digestion?

What is Monogastric Digestion?

The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Physiology of Enteric Nervous System and Gut Health

Physiology of Enteric Nervous System and Gut Health

The gastrointestinal tract, responsible for the digestion and absorption of nutrients, is safeguarded by the intestinal barrier, which consists of secretory, physical, and immune components. At the forefront is the secretory barrier, composed of essential elements such as mucus, gut microbiota, and defense proteins. They collaborate to break down food particles, facilitate nutrient absorption, and maintain optimal gut health. These secretory components ensure the smooth functioning of the...

Summary

This summary is machine-generated.

Alpha-synuclein (αS) acts as an antimicrobial peptide in the gut, protecting enteric nerves from infection. Its accumulation in the enteric nervous system (ENS) may lead to Parkinson's disease, suggesting therapeutic targets.

Keywords:

Antimicrobial peptides Parkinson’s disease alpha-synuclein enteric nervous system

Area of Science:

Neuroimmunology
Gastroenterology
Microbiology

Background:

The gastrointestinal (GI) tract possesses innate immune defenses involving enteric nerves.
Neuropeptides and alpha-synuclein (αS) exhibit antimicrobial properties and modulate immune responses.
αS is induced in nerve cells during infection and confers resistance.

Purpose of the Study:

To investigate the role of alpha-synuclein (αS) in the gastrointestinal immune system.
To explore the link between αS, enteric infections, and neurodegenerative diseases like Parkinson's disease.

Main Methods:

Biophysical characterization of αS.
Analysis of αS induction in nerve cells during infection.
Investigation of αS trafficking to the central nervous system (CNS).

Main Results:

αS demonstrates antimicrobial activity and enhances nerve cell resistance to viral infections.
αS attracts immune cells like neutrophils and macrophages, and activates dendritic cells.
Chronic GI infection can lead to αS aggregation in the enteric nervous system (ENS), potentially causing neurotoxicity and Parkinson's disease.

Conclusions:

αS plays a dual role in immunity and neurodegeneration.
Targeting αS aggregation in the ENS may offer a therapeutic strategy for Parkinson's disease.
