Abstract:
Pyroptosis is a unique form of programmed cell death characterized by intense inflammation. It involves the activation of Gasdermin proteins, which form membrane pores, leading to rapid cell rupture and the release of inflammatory molecules. Unlike other types of cell death, pyroptosis has distinct activation mechanisms and plays a complex role in chronic intestinal diseases, including inflammatory bowel disease, intestinal fibrosis, chronic infectious enteritis, and colorectal cancer. This review comprehensively examines how pyroptosis influences disease development and progression while exploring the therapeutic potential of targeting pyroptosis-related pathways. Moreover, the complex interplay between gut microbiota and pyroptosis is summarized, highlighting its critical role in the pathogenesis of chronic intestinal disorders. A deeper understanding of pyroptosis-related mechanisms in these diseases may provide valuable insights for future research and contribute to the development of innovative therapeutic strategies in gastroenterology.
Insights
Pyroptosis, a programmed cell death, drives inflammation in chronic gut diseases. Targeting pyroptosis pathways offers new therapeutic strategies for conditions like inflammatory bowel disease and colorectal cancer.
Area of Science:
- Gastroenterology
- Cell Biology
- Immunology
Background:
- Pyroptosis is a highly inflammatory form of programmed cell death.
- It involves Gasdermin protein activation, pore formation, and cell lysis.
- Distinct mechanisms differentiate pyroptosis from other cell death types.
Purpose of the Study:
- To review the role of pyroptosis in chronic intestinal diseases.
- To explore therapeutic strategies targeting pyroptosis.
- To summarize the gut microbiota's influence on pyroptosis in intestinal disorders.
Main Methods:
- Literature review of pyroptosis mechanisms.
- Analysis of pyroptosis's role in inflammatory bowel disease, intestinal fibrosis, infectious enteritis, and colorectal cancer.
- Examination of therapeutic targets and gut microbiota interactions.
Main Results:
- Pyroptosis significantly influences the development and progression of chronic intestinal diseases.
- Targeting pyroptosis pathways shows therapeutic potential.
- Gut microbiota play a critical role in pyroptosis-driven intestinal pathogenesis.
Conclusions:
- Understanding pyroptosis mechanisms is crucial for advancing gastroenterology.
- Targeting pyroptosis offers novel therapeutic avenues for chronic intestinal disorders.
- The interplay between gut microbiota and pyroptosis is key to disease pathogenesis.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
