Lung blood-vessel cell structure and ARDS
Cytoskeletal Regulation of Lung Endothelial Pathobiology in ARDS
This project looks at how the internal skeleton of lung blood-vessel cells makes vessels leak in adults with ARDS and aims to find targets for new treatments.

What this research studies
From your perspective, researchers are studying how the internal framework (the cytoskeleton) of lung endothelial cells controls whether blood vessels stay sealed or become leaky during ARDS and ventilator-induced injury. They use molecular and genomic testing, lab models, and analysis of human genetic differences—especially in people of African descent—to pinpoint genes, SNPs, and epigenetic sites involved in barrier repair. The team examines how reactive oxygen species change cell structure, focal adhesions, and lamellipodia that drive barrier integrity, and they test molecular approaches that might reduce permeability and inflammation. Results are intended to identify new drug targets and move promising therapies toward clinical testing.
Who could benefit from this research
Good fit: Adults with ARDS (including COVID-19–related ARDS), ARDS survivors, and people of African descent interested in genetic or biospecimen studies would be the most likely candidates to participate.
Not a fit: Children, people without ARDS, and those with unrelated chronic lung conditions or unwilling to provide samples are unlikely to receive direct benefit from this project.
Why it matters
Potential benefit: If successful, this work could lead to treatments that reduce lung blood-vessel leak and inflammation, lowering organ failure and deaths from ARDS.
How similar studies have performed: Previous laboratory and animal studies have shown promising approaches to stabilize the lung vascular barrier, but there are currently no widely approved drugs that stop ARDS vascular leak, so this work builds on preclinical findings toward clinical solutions.
