NIH-funded research R21 grant

Investigating how ozone exposure affects mucus production in the airways

Official title: Pathogenesis of mucous cell metaplasia in ozone-exposed airways

Funded at North Carolina State University Raleigh · NIH-11000656 · Data updated 2026-11-12

This study is looking at how breathing in higher levels of ozone can cause more mucus to build up in the airways, especially in kids and older adults, and aims to find ways to help people with breathing problems caused by too much mucus.

Who could benefit from this research

Could help

Ideal candidates for this research include children and elderly individuals with pre-existing respiratory conditions such as asthma or chronic bronchitis.

Less likely to help

Patients without respiratory conditions or those living in areas with low ozone exposure may not benefit from this research.

What this research studies

This research focuses on understanding how exposure to elevated levels of ozone can lead to increased mucus production in the airways, particularly in vulnerable populations such as children and the elderly. The study examines the mechanisms behind mucous cell metaplasia (MCM), a condition where airway cells change and produce excess mucus, worsening respiratory symptoms. By using animal models, researchers will explore how repeated ozone exposure impacts lung function and mucus production, aiming to identify potential therapeutic strategies for those suffering from muco-obstructive airway diseases.

Why it matters

Potential benefit: If successful, this research could lead to improved treatments for patients with respiratory conditions exacerbated by air pollution.

How similar studies have gone: Previous studies have shown that understanding the effects of environmental pollutants like ozone can lead to significant advancements in treating respiratory diseases, indicating a promising avenue for this research.
