Who could benefit from this research

Could help

Patients with a history of severe viral infection and ongoing lung fibrosis or dyspnea may be eligible for future related studies and tissue/biospecimen contributions.

Less likely to help

Patients without post-viral lung complications or fibrosis may not directly benefit from this work.

What this research studies

The grant will use mouse models and patient samples to map how immune cells, especially CD8 T cells, interact with lung tissue to cause chronic inflammation and fibrosis after viral infections. Researchers will look at how immune signals keep T cells active and how this affects the fate of airway cells and the surrounding macrophage environment. The work aims to connect these immune processes to observed patterns of lung scarring seen in patients with post-viral fibrosis and other lung diseases. By coordinating with core facilities, the project will integrate data across models and human samples to build a systems-level view of virus-driven lung fibrosis.

Why it matters

Potential benefit: If successful, this work could identify targets to prevent or treat chronic lung scarring after viral infections, potentially improving breathing and quality of life for affected patients.

How similar studies have gone: Prior research in lung fibrosis has shown immune-epithelial interactions contribute to scarring, but this project aims to clarify mechanisms in post-viral contexts.
