Modern diets promote metabolic diseases by altering gut bacteria. Pathogenic bacteria use the type III secretion system (T3SS) to cause disease, and this review explores its role in metabolic disorders.
Area of Science:
- Microbiology
- Metabolic Diseases
- Gut Microbiota
Background:
- Modern lifestyles, characterized by high salt, sugar, and fat diets, are increasing chronic metabolic diseases like diabetes, obesity, and gout.
- Gut microbiota composition and diversity are significantly influenced by lifestyle and are closely linked to metabolic disease development.
- Pathogenic bacteria, including *Yersinia*, *Salmonella*, *Shigella*, and pathogenic *E. coli*, employ the type III secretion system (T3SS) for virulence.
Purpose of the Study:
- To review the structure and function of the type III secretion system (T3SS).
- To explore the role of T3SS in disrupting intestinal barrier integrity.
- To investigate the connection between T3SS-containing gut bacteria and metabolic diseases, including potential mechanisms and therapeutic applications.
Main Methods:
- Literature review on the type III secretion system (T3SS).
- Analysis of T3SS's role in intestinal barrier function.
- Examination of T3SS in the context of gut microbiota changes in metabolic diseases.
Main Results:
- The type III secretion system (T3SS) is crucial for the virulence of many human pathogens.
- T3SS contributes to the disruption of intestinal barrier integrity.
- Changes in T3SS-carrying bacteria are observed in metabolic diseases, suggesting a potential link.
Conclusions:
- The type III secretion system (T3SS) may play a significant role in the development and progression of metabolic diseases.
- Targeting the T3SS presents a potential therapeutic strategy for metabolic diseases.
- Further research into T3SS mechanisms and applications is warranted for disease diagnosis, prevention, and treatment.

Physiology of the Gastrointestinal System II: Digestion and Absorption
Digestion begins in the mouth, where food undergoes mechanical breakdown by chewing and combines with saliva. Salivary amylase, an enzyme in saliva, starts the breakdown of starches into maltose. The food then travels down the esophagus to the stomach.
In the stomach, a...
