Inflammatory bowel disease (IBD) involves T helper 17 (Th17) cells, a distinct T-cell lineage. Interleukin-23 (IL-23) amplifies Th17-driven inflammation, offering new therapeutic targets for IBD.
Area of Science:
- Immunology
- Gastroenterology
- Cell Biology
Background:
- Inflammatory bowel disease (IBD) pathogenesis traditionally linked to T helper 1 (Th1) and T helper 2 (Th2) responses.
- Emerging evidence implicates a distinct T helper cell subset, Th17 cells, in driving gut inflammation in IBD.
- The cytokine IL-23, produced by antigen-presenting cells, is crucial for Th17 cell amplification and associated inflammation.
Purpose of the Study:
- To review the role of Th17 cells in the modulation of intestinal tissue inflammation in IBD.
- To discuss the interplay between Th17 cells and other mucosal cell types in IBD pathogenesis.
- To highlight new therapeutic strategies targeting Th17-mediated pathways in IBD.
Main Methods:
- Literature review of existing data on Th17 cells in IBD.
- Analysis of cytokine production and T-cell responses in the gut mucosa.
- Examination of the role of IL-23 in amplifying Th17 cell activity.
Main Results:
- Th17 cells are key players in the immune-mediated pathology of IBD.
- IL-23 is essential for sustaining Th17 cell-driven intestinal inflammation.
- Understanding Th17 cell interactions elucidates novel pathways of intestinal tissue damage.
Conclusions:
- Th17 cells represent a critical component of the inflammatory response in IBD.
- Targeting the IL-23/Th17 axis offers promising therapeutic avenues for IBD treatment.
- Further research into mucosal cell interactions is vital for comprehensive IBD management.

Inflammatory Bowel Disease II: Crohn's Disease
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 transmural...
Inflammatory Bowel Disease I: Ulcerative Colitis
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...
