Why COVID-19 affects people’s lungs differently

Mechanistic modeling of the innate immune responses of the human lung to understand the inter-individual heterogeneity of COVID-19 pneumonia

NIH-funded research University of Florida · NIH-11132659

Researchers will use lab-grown 3D lung tissue, mice with the human ACE2 receptor, and computer models to find biological reasons some people with COVID-19 develop severe pneumonia while others do not.

What this research studies

If you've had COVID-19, this project looks at why some people get much worse lung disease than others by combining lab-grown 3D human lung tissue, mice engineered with the human ACE2 receptor, and personalized computer simulations of infection. The team will expand a multi-scale mathematical model and tailor it to individual biological differences using data from the 3D cultures and animal studies. They will test whether different activation of the mTOR pathway in type I alveolar epithelial cells helps explain divergent outcomes. The aim is to identify host-specific immune pathways that could guide more personalized approaches to preventing or treating severe COVID-19 pneumonia.

Who could benefit from this research

Good fit: Adults who have had SARS-CoV-2 infection or who can provide clinical data or biological samples for model personalization would be the most relevant candidates.

Not a fit: People without any connection to SARS-CoV-2 infection or those seeking immediate clinical treatment are unlikely to receive direct benefit from this primarily lab- and model-focused research.

Why it matters

Potential benefit: If successful, this work could identify biological markers and host-targeted strategies to reduce the risk of severe COVID-19 pneumonia in individual patients.

How similar studies have performed: Related 3D lung models, animal studies, and computational approaches have previously helped reveal disease mechanisms, but the specific combination and personalization proposed here is relatively novel for COVID-19.
