Title	Predictive protein biomarker signatures and the corresponding transcriptional cell state changes in human lung fibrosis
Description	Single cell genomics enables characterization of disease specific cell states, while improvements in mass spectrometry workflows bring the clinical use of body fluid proteomics within sight. However, the correspondence of peripheral protein signatures with cell state changes in diseased organs is currently unknown. Here, we use single cell RNA-seq and proteomics from large patient cohorts of pulmonary fibrosis and establish that predictive protein signatures in body fluids correspond to specific cellular changes in the lung. We determined transcriptional changes in 45 cell types across three patient cohorts and quantified bronchoalveolar lavage fluid and plasma proteins to discover protein signatures and associated cell state changes that were linked to diagnosis, lung function, smoking and injury status. Altered expression of the novel marker of lung health CRTAC1 in alveolar epithelium is robustly reported in patient plasma. With further improvements of this concept and deeper coverage of plasma proteomes, we envision future longitudinal profiling of body fluid signatures coupled to deep learning for non-invasive prediction and monitoring of pathological cell state changes in patient organs.
