1222-Cellular Origins of Checkpoint Inhibitor
This research identifies the distinct cellular mechanisms behind checkpoint inhibitor pneumonitis (CIP) and radiation pneumonitis (RP) through advanced single-cell profiling of lung and blood samples. The study demonstrates that CIP is primarily driven by tissue-resident ZNF683hi CD8+ exhausted T cells, whereas RP originates from peripherally derived GZMKhi CD8+ T cells. These divergent biological pathways offer clear mechanistic differences that help clinicians distinguish between the two types of lung inflammation. By identifying specific cytological biomarkers, such as the CD8+ T/CD4+ T…
