Cell-cell and cell-matrix interactions driving progressive fibrosis in interstitial lung diseases

NIH-funded research University of California Los Angeles · NIH-11178483

What this research studies

As someone living with or at risk for ILD, this project explains how injured airway lining cells signal to nearby support cells and alter the tissue around them, leading to progressive scarring. Researchers will study very early lung lesions called interstitial lung abnormalities (ILA), early symptomatic ILD tissue, and later regions that still contain epithelial cells using patient-derived samples. They will combine spatial transcriptomics, single-cell protein secretion analysis, small-region proteomics, and a 3D scaffolded lung cell co-culture model that mimics progressive fibrosis. The work aims to map the cell-to-cell and cell-to-matrix conversations that start and sustain fibrosis.

Who could benefit from this research

Good fit: People with interstitial lung disease, especially those with interstitial lung abnormalities (ILA) or early-stage symptoms, would be the most relevant candidates.

Not a fit: Patients with very advanced, end-stage pulmonary fibrosis where most epithelial cells are lost, or people without ILD, are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could identify early drivers of lung scarring and point to ways to stop or slow fibrosis before severe lung damage occurs.

How similar studies have performed: Most prior studies focused on end-stage fibrotic lungs, so combining early human lesion samples with 3D models and spatial molecular tools is relatively new though supported by emerging technologies.
