Pulmonary alveolar proteinosis is a rare condition characterized by accumulation of intra-alveolar surfactant. Here, we report a case of interstitial lung disease which developed over the years in a patient with pulmonary alveolar proteinosis.

Radiotherapy can be limited by pneumonitis which is impacted by innate immunity, including pathways regulated by TRAIL death receptor DR5. We investigated whether DR5 agonists could rescue mice from toxic effects of radiation and found two different agonists, parenteral PEGylated trimeric-TRAIL (TLY012) and oral TRAIL-Inducing Compound (TIC10/ONC201) could reduce pneumonitis, alveolar-wall thickness, and oxygen desaturation. Lung protection extended to late effects of radiation including less fibrosis at 22-weeks in TLY012-rescued survivors versus un-rescued surviving irradiated-mice.

Background: Acute lung injury (ALI) is a severe condition with multifaceted causes, including inflammation and oxidative stress. This research investigates the influence of m6A (N6-methyladenosine) modification on GBP4, a protein pivotal for macrophage polarization, a critical immune response in ALI.
Methods: Utilizing a mouse model to induce ALI, the study analyzed GBP4 expression in alveolar macrophages.

Background: Recent advances in comprehensive gene analysis revealed the heterogeneity of mouse lung fibroblasts. However, direct comparisons between these subpopulations are limited due to challenges in isolating target subpopulations without gene-specific reporter mouse lines. In addition, the properties of lung lipofibroblasts remain unclear, particularly regarding the appropriate cell surface marker and the niche capacity for alveolar epithelial cell type 2 (AT2), an alveolar tissue stem cell.

Background: Lung ultrasound (LUS) is increasingly utilized in veterinary medicine to assess pulmonary conditions. However, the characterization of pleural line and subpleural fields using different ultrasound transducers, specifically high-frequency linear ultrasound transducers (HFLUT) and curvilinear transducers (CUT), remains underexplored in canine patients. This study aimed to evaluate inter-rater agreement in the characterization of pleural line and subpleural fields using B- and M-mode ultrasonography in dogs with and without respiratory distress.
