Cell stress in the lung that may cause long-term transplant failure

Pathological activation of integrated stress response as a driver of Chronic allograft dysfunction after lung transplant

NIH-funded research Northwestern University · NIH-11252538

What this research studies

If you have had a lung transplant, researchers will collect airway samples and clinical data early after transplant and during follow-up to search for signs of a persistent cellular stress response. They will link early problems after surgery (primary graft dysfunction) with later scarring and chronic lung allograft dysfunction by measuring stress-related signals in airway and alveolar cells. Laboratory studies will use those human-derived samples alongside experimental models to test whether blocking the integrated stress response helps airway cells recover and prevents scarring. The work aims to connect what is seen in patients with molecular targets that could be used in future treatments.

Who could benefit from this research

Good fit: Ideal candidates are recent or past lung transplant recipients who can provide clinical follow-up and agree to airway sampling such as bronchoscopy/bronchoalveolar lavage.

Not a fit: People without a lung transplant or those who cannot undergo airway sampling or follow-up visits are unlikely to benefit directly from participation in this project.

Why it matters

Potential benefit: If successful, this work could point to new ways to prevent or treat chronic lung transplant failure and improve long-term survival and quality of life for transplant recipients.

How similar studies have performed: Prior laboratory and animal studies have linked immune cells and the integrated stress response to poor repair, but translating this link to human lung transplant outcomes is a newer and less-tested approach.
