Why people with osteogenesis imperfecta have lung problems

Investigating pulmonary complications due to abnormal collagen/ER stress in Osteogenesis Imperfecta

NIH-funded research University of California Los Angeles · NIH-11309113

This project looks at whether faulty type I collagen and ongoing cell stress cause lung damage and breathing problems in people with osteogenesis imperfecta.

What this research studies

Researchers will use two mouse models that carry common type I collagen mutations seen in OI to mimic how the disease may affect the lungs. They will study lung structure, cell types, and cell-to-cell communication at multiple stages of development and after lung injury. The team will measure abnormal collagen secretion, signs of chronic endoplasmic reticulum (ER) stress in collagen-producing cells, and changes in signaling pathways. Results will be compared to known OI lung problems to help point toward ways to monitor or protect lungs in people with OI.

Who could benefit from this research

Good fit: People with osteogenesis imperfecta, particularly those with known type I collagen mutations or with respiratory symptoms, would be most relevant to this research.

Not a fit: People without OI or whose lung disease is caused by unrelated conditions are unlikely to benefit directly from this specific project.

Why it matters

Potential benefit: If successful, this work could identify mechanisms behind lung problems in OI and suggest targets for monitoring or future treatments to protect breathing.

How similar studies have performed: Previous lab and animal work has suggested abnormal collagen and ER stress affect tissues in OI, but applying those findings to lung structure and therapies remains largely untested.
