Exploring the Anti-Inflammatory Effect of Inulin by Integrating Transcriptomic and Proteomic Analyses in a Murine...

Area of Science:

• Immunology
• Nutritional Science
• Microbiology

Background:

• Inulin is a prebiotic soluble fiber with anti-inflammatory potential.
• Macrophages play a key role in gut microbiota-related inflammatory diseases.
• Understanding inulin's immunomodulatory mechanisms is crucial for health applications.

Purpose of the Study:

• To evaluate the anti-inflammatory properties of inulin in a murine macrophage model.
• To investigate the immunomodulatory mechanisms of inulin using omics technologies.
• To identify molecular targets for inulin's anti-inflammatory effects.

Main Methods:

• Murine macrophage (RAW 264.7) cell model of inflammation.
• Transcriptomic and proteomic analyses (omics technologies).
• Functional analysis of omics data to identify signaling pathways.

Main Results:

• Inulin demonstrated anti-inflammatory effects in macrophages.
• Omics data revealed inhibition of the NF-κB pathway, reducing pro-inflammatory factors like COX2.
• Inulin promoted the Nrf2 pathway, upregulating the phase II defense protein Hmox1.

Conclusions:

• Inulin exerts anti-inflammatory effects via NF-κB inhibition and Nrf2 activation in macrophages.
• These findings provide targets for immune modulation by dietary fibers.
• Inulin offers potential for developing functional foods and nutraceuticals for personalized nutrition.
