Circulating Biomarker Analyses in a Longitudinal Cohort of Patients with IPF
In this study, we asked whether levels of select circulating biomarkers in patients with IPF demonstrated changes in response to treatment over time, and whether treatment with pirfenidone and nintedanib led to differential biomarker expression. Serial plasma samples from 48 IPF patients on usual treatment and 6 healthy volunteers were analyzed to identify differentially expressed blood protein. Hypothesis-driven potential biomarker selection was based on recent literature, internal preclinical data, and the PROLIFIC Consortium (1) proposed biomarkers of pulmonary fibrosis. We compared our findings to public databases to p...

Small airway fibroblasts from Chronic Obstructive Pulmonary Disease patients exhibit cellular senescence
CONCLUSIONS: These data suggest COPD SAF are senescent and may be associated with fibrotic properties and mitochondrial dysfunction. Further understanding cellular senescence in SAF may lead to potential therapies to limit SAD progression.PMID:38150543 | DOI:10.1152/ajplung.00419.2022 (Source: American Journal of Physiology.

Viral airway injury promotes cell engraftment in an in vitro model of cystic fibrosis cell therapy
We examined competition dynamics by time-lapse confocal imaging and found that delivered cells accelerate airway regeneration by incorporating into the epithelium. Irradiating the repairing epithelium granted engrafting cells a competitive advantage by diminishing resident stem cell proliferation. Intentionally, causing severe injury to the lungs of people with CF would be dangerous. However, naturally occurring events like viral infection can induce similar epithelial damage with patches of denuded epithelium. We found that viral preconditioning promoted effective engraftment of cells primed for viral resistance.NEW &...

Hemopexin Reverses Activation of Lung eIF2a and Decreases Mitochondrial Injury in Chlorine Exposed Mice
Am J Physiol Lung Cell Mol Physiol. 2023 Dec 27. doi: 10.1152/ajplung.00273.2023. Online ahead of print.ABSTRACTWe assessed the mechanisms by which non-encapsulated heme, released in the plasma of mice post exposure to chlorine (Cl2) gas, resulted in the initiation and propagation of acute lung injury. We exposed adult male and female C57BL/6 mice to Cl2 (500 ppm for 30 min), returned them to room air, and injected them intramuscularly with either human hemopexin (hHPX; 5 µg/ g BW in 50 µl saline) or vehicle at 1h post exposure. Upon return to room air, Cl2 exposed mice, injected with vehicle, developed respiratory acido...
