Airway cell and immune cell talks in lung transplant failure

Official title: Airway epithelial cell and lymphocyte interactions in chronic lung allograft dysfunction pathogenesis

Funded at University of California, San Francisco · NIH-11629839 · Data updated 2026-11-12

This grant tests how airway cells and immune cells interact to drive chronic rejection after lung transplant, with the goal of slowing or preventing scar-like damage.

Who could benefit from this research

Could help

Lung transplant recipients or airway samples from those patients who develop chronic lung allograft dysfunction.

Less likely to help

If you do not have a lung transplant or CLAD, this study is unlikely to affect you.

What this research studies

If funded, researchers will study how airway epithelial cells and activated lymphocytes communicate during chronic lung allograft dysfunction, using patient-derived airway brushings and laboratory models to map gene expression and signaling pathways. They will focus on hypoxia-related changes and TNF-related apoptotic signals that may push T cells to attack the transplanted lung. The work builds on transcriptional analyses already done at multiple transplant centers to uncover mechanisms behind CLAD. Findings could reveal new targets to interrupt this harmful crosstalk and improve long-term lung function after transplant.

Why it matters

Potential benefit: Understanding these interactions could lead to therapies that reduce CLAD risk and help transplant recipients breathe easier longer.

How similar studies have gone: Prior work from multiple centers has linked gene expression changes to CLAD, suggesting this approach can identify meaningful mechanisms.
