IBD immunopathogenesis: A comprehensive review of inflammatory molecules

Area of Science:

• Gastroenterology and Immunology
• Molecular Biology

Background:

• Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, involves chronic gastrointestinal inflammation.
• Imbalances in pro- and anti-inflammatory molecules disrupt gut immunity, driving IBD pathogenesis.
• Research focuses on identifying novel molecular targets for IBD therapy.

Purpose of the Study:

• To comprehensively review the roles of various inflammatory molecules in IBD.
• To analyze the expression status of these molecules in ulcerative colitis and Crohn's disease.
• To elucidate their impact on the intestinal inflammatory process.

Main Methods:

• Literature review of inflammatory molecules in IBD.
• Analysis of cytokines, chemokines, inflammasomes, microRNAs, and neuropeptides.
• Comparison of molecular expression in ulcerative colitis versus Crohn's disease.

Main Results:

• Inflammatory molecules significantly contribute to IBD development and progression.
• Distinct immunopathogenesis exists between ulcerative colitis and Crohn's disease, despite shared symptoms.
• Specific molecules show differential expression patterns in each IBD type.

Conclusions:

• Targeting specific inflammatory molecules offers potential therapeutic strategies for IBD.
• Understanding molecular differences is crucial for differentiating and treating ulcerative colitis and Crohn's disease.
• Further research into these molecules can refine IBD management.
