Omega-3s that help immune cells calm dust-related lung inflammation
Omega-3 fatty acids induce macrophage IL-22 signaling to promote resolution of dust-induced lung inflammation
This project looks at whether omega-3 fats and their natural products can switch on lung immune signals to help people with dust-related airway inflammation heal better.

What this research studies
This project examines how omega-3 fats like DHA and a related molecule called maresin-1 activate IL-22 signaling in lung macrophages. Researchers use laboratory studies with lung cells and animal models of repeated dust inhalation to see how these signals affect airway inflammation and repair. They will measure immune responses, epithelial barrier health, and levels of pro-resolving lipids to understand the protective mechanism. Findings will be compared to human lung biology where possible to guide future patient-focused trials.
Who could benefit from this research
Good fit: People with airway inflammation from repeated dust exposures — for example farmers, agricultural workers, or others with dust-related chronic bronchitis or similar conditions — would be the most relevant candidates for future trials based on this work.
Not a fit: Patients whose lung problems are primarily due to infections, genetic or structural lung disease, or causes unrelated to dust-driven inflammation may not benefit from interventions targeting this pathway.
Why it matters
Potential benefit: If successful, this work could point to dietary or drug strategies using omega-3–derived molecules to reduce dust-related airway inflammation and improve lung healing.
How similar studies have performed: Previous lab and animal studies have shown omega-3s and specialized pro-resolving mediators can reduce lung inflammation, but activating IL-22 in macrophages is a new finding and human benefits remain unproven.
