Immune communication in lung scarring and injury

Immune crosstalk in lung injury and fibrosis

NIH-funded research University of Michigan at Ann Arbor · NIH-11251966

What this research studies

If you have lung injury or scarring (fibrosis), this research looks at how lung cells send signals that bring in immune cells and drive scarring. The team focuses on a molecule called HB-EGF made by epithelial cells and how cell-to-cell contact changes immune behavior. They will use lab experiments, animal models, and human tissue or patient samples to study why fibrotic lungs struggle to recruit neutrophils and fail to clear gram-positive bacteria. Understanding these steps could point to ways to protect people with fibrosis from infections and slow scarring.

Who could benefit from this research

Good fit: People with pulmonary fibrosis or those who have trouble clearing lung infections—such as some patients after hematopoietic stem cell transplant—are the most likely candidates.

Not a fit: People without lung disease or whose infections are primarily due to gram-negative bacteria are unlikely to see direct benefit from this specific work.

Why it matters

Potential benefit: Could point to new treatments that reduce lung scarring and help patients with fibrosis fight certain bacterial lung infections.

How similar studies have performed: Previous laboratory and animal studies link epithelial signals to fibrosis and the investigators' past work supports this approach, but the specific link between HB-EGF and poor gram-positive clearance is a relatively new focus.
