CD207‐Positive Dendritic Cells Promote Emphysema Through CD8+ T Cell Pathway in Chronic Obstructive Pulmonary Disease

Advanced Science, EarlyView.
CD207+ dendritic cells (DCs) drive emphysema by promoting CD8⁺ T cell cytotoxicity via Birbeck granule‐dependent MHC‐I antigen presentation. This DC subset is expanded by cigarette smoke‐induced oxidative stress, which triggers granulocyte‐macrophage colony‐stimulating factor (GM‐CSF) release from airway epithelium.

Rupestonic Acid of Artemisia Rupestris L. Extract Treats Pulmonary Fibrosis in COPD by Targeting TGF‐β1

Advanced Science, EarlyView.
RA of EEAR inhibits TGF‐β1 ubiquitination and changes conformation by target binding TGF‐β1, regulating TGF‐β1/Smad2/3 signaling pathway. Thus it down‐regulated downstream protein expression, inhibited EMT and collagen deposition of ECM, in order to EEAR preventing PF in COPD.

Spatial Profiling Reveals Distinct Molecular and Immune Evolution of Mouse Lung Adenocarcinoma Precancers with or Without Carcinogen Exposure

Advanced Science, EarlyView.
Tumor evolution in lung adenocarcinoma is shaped by genetic alterations and spatial immune dynamics. By integrating whole‐exome sequencing, imaging mass cytometry, and spatial transcriptomics across two mouse models, this study reveals how mutational burden, immune infiltration, and cell–state interactions evolve during early and late carcinogenesis ...
