Inflammatory bowel disease, past, present and future: lessons from animal models

Area of Science:

• Immunology
• Gastroenterology

Background:

• Inflammatory bowel disease (IBD) pathogenesis is more complex than initially understood.
• Disease mechanisms vary based on induction, cell type, disease stage, and environment.

Purpose of the Study:

• To review and synthesize current and emerging concepts in IBD pathogenesis.
• To bridge the gap between basic research (animal models) and clinical applications.

Main Methods:

• Literature review of IBD models and concepts.
• Discussion of key molecular and cellular players in IBD.
• Analysis of bench-to-bedside translation.

Main Results:

• IBD involves intricate interactions including T helper (Th) 1, Th2, Th17 cells, antigen presentation, and regulatory networks.
• Emerging concepts include NOD2, Toll-like receptors, microbiota-epithelial interactions, stem cells, autophagy, microRNAs, and glycoimmunology.

Conclusions:

• Novel concepts are refining our understanding of IBD mechanisms.
• Translating these bench discoveries to clinical practice is crucial for advancing IBD treatment.
