Lung-specific antibodies causing injury after lung transplant

Pathogenesis of lung injury mediated by lung-restricted antibodies

NIH-funded research Northwestern University · NIH-11377289

Looking at whether antibodies that attack lung proteins and certain donor immune cells cause early, serious lung injury after transplant and if blocking them can protect transplant recipients.

What this research studies

If you are getting a lung transplant, researchers will collect blood and lung samples from donors and recipients to look for antibodies that target lung proteins. They will measure immune signals such as complement activation and neutrophil recruitment and track donor and recipient immune cells that move into the new lung. Laboratory and animal experiments will test how these antibodies and cells cause damage and whether stopping their actions reduces injury. The team combines patient sample data with lab findings to identify targets for treatments to prevent primary graft dysfunction.

Who could benefit from this research

Good fit: Adults listed for or undergoing lung transplantation, especially those with chronic lung disease or ARDS, who can provide blood or lung samples and agree to follow-up.

Not a fit: People not undergoing lung transplant, children, or those unwilling to provide samples or visit the study center are unlikely to benefit directly.

Why it matters

Potential benefit: Could lead to new tests or treatments to prevent early transplant lung failure, improving short-term survival and long-term transplant outcomes.

How similar studies have performed: Prior clinical work has linked lung-restricted autoantibodies to worse early graft function, but treatments to block these effects remain mostly experimental.
