Pulmonary alveolar proteinosis (PAP) results from a dysfunction of alveolar macrophages (AMs), chiefly due to disruptions in the signaling of granulocyte macrophage colony-stimulating factor (GM-CSF). We found that mice deficient for the B lymphoid transcription repressor BTB and CNC homology 2 (Bac...

The chromatin remodeling complex PRC2 safeguards cell fate in alveolar epithelial type 2 cells
During influenza pneumonia, the alveolar epithelial cells of the lungs are targeted by influenza virus. The distal airway stem cells (DASCs) and proliferating alveolar type II (AT2) cells are reported to be putative lung repair cells. However, their relative spatial and temporal distribution is stil...

We compared gene expression in T1alpha (-/-) lungs vs wild type at dpc 18.5 when the phenotype is moderate and at term when the phenotype is more severe. Lungs present narrow and irregular alveolar spaces, thicker mesenchyme, reduced number of attenuated type I cells, normal numbers of type II cells...

Maintenance of the gas exchange surface throughout life and regeneration of the lung after injury requires tight regulation of epithelial cell fate and function. Alveolar epithelial type 2 (AT2) cells serve as the progenitors of the distal epithelium, differentiating into alveolar epithelial type 1 ...

Obstructive sleep apnea (OSA) leads to increased cardiovascular morbidity and mortality, which have been attributed to intermittent hypoxia (IH). The effects of IH on lung structure and function are unknown. We used a mouse model of chronic IH, which mimics the O2 profile in patients with OSA. We ex...
