Boosting protective lung immune cells to prevent ozone-related breathing disease

Harnessing Inflammatory Macrophages to Thwart Lung Disease Caused by Chronic Ozone Exposure

NIH-funded research Rutgers Biomedical and Health Sciences · NIH-11240276

This project aims to restore a natural switch in lung immune cells so people with long-term ozone-related inflammation (such as asthma or COPD) may heal their lungs instead of staying stuck in damaging inflammation.

What this research studies

Researchers are studying lung immune cells called macrophages to understand why they fail to switch from a proinflammatory to a healing state after repeated ozone exposure. They found a regulator called the farnesoid-X receptor (FXR) that helps this healing switch but becomes decreased after ozone exposure. Using laboratory and animal experiments, the team will work out how ozone suppresses FXR and whether restoring FXR activity helps lungs resolve inflammation. The goal is to point toward treatments that encourage the lungs to heal rather than only quieting inflammation temporarily.

Who could benefit from this research

Good fit: People with asthma or COPD thought to be worsened by repeated ozone or air-pollution exposure would be the most relevant candidates.

Not a fit: Patients whose lung disease is driven mainly by other causes (for example, long-term heavy smoking, certain genetic disorders, or active infection) may not benefit from this approach.

Why it matters

Potential benefit: Could lead to new therapies that help the lungs resolve pollution-driven inflammation and reduce the risk or severity of chronic asthma and COPD.

How similar studies have performed: Preclinical studies support a role for FXR in promoting macrophage reprogramming and reducing lung inflammation, but translating this into human therapies is still largely untested.
