Dysregulated immunometabolism in gut inflammation

Area of Science:

• Gastroenterology
• Immunology
• Metabolic Biology

Background:

• Gut inflammatory diseases, including inflammatory bowel disease (IBD), are common intestinal disorders.
• Immune cell function is critical for gut homeostasis, balancing pro-inflammatory and anti-inflammatory signals.
• Dysregulated immune cell activity can lead to tissue damage and disease exacerbation.

Purpose of the Study:

• To explore how metabolic reprogramming influences immune cell function in intestinal inflammatory diseases.
• To review the impact of cellular metabolism and microenvironmental changes on immune cells.
• To connect metabolic alterations to disease progression in the gut.

Main Methods:

• Review of existing literature on immune cell metabolism in inflammatory conditions.
• Analysis of metabolic reprogramming in immune cells (e.g., macrophages).
• Examination of microenvironmental metabolites and their effects on immune responses (e.g., bile acids).

Main Results:

• Metabolic reprogramming is a key regulator of immune cell function and polarization in inflammation.
• Altered cellular energy metabolism (glycolysis, fatty acid oxidation) affects immune cell phenotypes.
• Microenvironmental metabolites modulate immune cell differentiation and balance (e.g., Th17/Treg).

Conclusions:

• Cellular metabolic reprogramming, microenvironmental changes, and gut dysbiosis collectively impact immune cell behavior.
• These metabolic factors influence immune cell differentiation, proliferation, and function in intestinal inflammation.
• Understanding these metabolic-immune interactions is vital for addressing disease progression in gut inflammatory disorders.
