How air pollution harms heart and lung inflammation

Air pollution disrupts Inflammasome Regulation in HEart And Lung Total Health (AIRHEALTH)

NIH-funded research Harvard University D/b/a Harvard School of Public Health · NIH-11169783

This work looks at how traffic and wildfire pollution trigger inflammatory signals like IL‑1β in lungs and the heart, which matters for people with asthma or heart disease.

What this research studies

This project studies how tiny particles from car exhaust and wildfires activate inflammatory pathways such as IL‑1β that can damage lung and heart tissue. Researchers will combine blood and tissue biomarker work with lab experiments in cells/animals and computer-based systems biology to map the key steps in that response. The team plans to use human biomarker samples alongside unbiased molecular analyses to find points where existing drugs or new therapies could block harmful inflammation. If you live in polluted areas or have asthma or heart disease, their findings could point to treatments or public-health steps that reduce your risk.

Who could benefit from this research

Good fit: People exposed to high air pollution—including children, adolescents, people with asthma, or those with cardiovascular disease—would be the most relevant candidates for participation or future therapies.

Not a fit: People without significant pollution exposure or without cardiopulmonary conditions are less likely to benefit directly from these findings in the near term.

Why it matters

Potential benefit: If successful, this could point to treatments (for example drugs that block IL‑1β) or policy actions that lower pollution-related lung and heart harm.

How similar studies have performed: Prior clinical work targeting IL‑1β has reduced certain types of heart inflammation, but applying that approach specifically to pollution-triggered disease is still emerging.
