587-The Cellular Landscape and Heterogeneity of COPD
This research study utilizes single-nucleus RNA sequencing and spatial transcriptomics to establish a biological framework for Chronic Obstructive Pulmonary Disease (COPD). By analyzing lung tissue and plasma, researchers identified that the disease is not a single entity but a collection of aberrant cell states, including specific shifts in epithelial, endothelial, and fibroblast populations. The findings show that as the disease progresses, cells responsible for gas exchange decline while inflammatory and remodeling cell types increase. The study also identifies protein biomarkers in the…
