Aim: To identify the molecular signature of differentially expressed genes (DEGs) associated with PANoptosis in idiopathic pulmonary fibrosis (IPF) and to interpret their immune landscape and cellular distribution characteristics.
Methods And Results: We acquired two IPF datasets from the Gene Expression Omnibus (GEO) database to identify PANoptosis-related DGEs (PAN-DEGs), initially identifying thirty PAN-DEGs. Utilizing machine learning algorithms, we established a five-gene PANoptosis-related signature comprising IGF1, GPX3, GADD45β, SMAD7, and TIMP3, each demonstrating robust diagnostic performance. The expression of these hub genes was subsequently validated using a third GEO dataset and a bleomycin-induced pulmonary fibrosis model. Immune infiltration analysis revealed a close association of these genes with various immune cells, and single-cell RNA sequencing indicated significant expression changes in diverse pulmonary cell types, particularly endothelial cells and fibroblasts.
Conclusion: We identified and validated a PANoptosis-related gene signature in IPF, providing insights into their immune infiltration and potential cellular distribution. Further research is necessary to elucidate the biological functions and mechanisms of these genes in the pathogenesis of IPF.

Mechanistic studies have been suggested that toxic effects of bleomycin are generally attributed to formation of free radicals, mitochondria damages, oxidative stress and inflammation. For this purpose, we explored the direct exposure of bleomycin and protective effects of the betanin and vanillic acid separately against its possible toxicity in rat lung isolated mitochondria. Various mitochondrial toxicity parameters were evaluated including; succinate dehydrogenases (SDH) activity, reactive oxygen species (ROS) formation, mitochondrial swelling, mitochondrial membrane potential (MMP) collapse, malondialdehyde (MDA) and glutathione disulfide (GSSG) levels.

Objectives: To investigate the effect of (HP) on bleomycin (BLM)-induced pulmonary fibrosis in mice and on TGF-β1-induced human fetal lung fibroblasts (HFL1).
Methods: Thirty male C57BL/6 mice were randomly divided into control group, BLM-induced pulmonary fibrosis model group, low- and high-dose HP treatment groups (3 and 21 mg/kg, respectively), and 300 mg/kg pirfenidone (positive control) group. The effects of drug treatment for 21 days were assessed by examining respiratory function, lung histopathology, and expression of fibrosis markers in the lung tissues of the mouse models.

Background: Hermansky-Pudlak syndrome (HPS) is a rare disease characterized by excessive bleeding, oculocutaneous albinism, and pulmonary fibrosis (PF). However, few studies have systematically summarized the clinical characteristics of HPS.
Objectives: To summarize the clinical characteristics, risk factors of PF, radiological and pathological presentations, and prognostic factors in patients with HPS.

Recent improvements in cell-free DNA technology have enabled non-invasive prenatal testing (NIPT) to screen for fetal single-gene autosomal recessive conditions from maternal blood as early as the first trimester. This technique can determine the fetal risk for cystic fibrosis (CF) with a single blood sample from a pregnant person without the need for a partner sample, which is required for traditional carrier screening. A retrospective review of 100,106 consecutive general-risk pregnant patients who underwent CF carrier screening was completed.

This study introduces a novel dual-sensitive drug delivery system, gelatin-coated chitosan microparticles (GL-ChMPs), designed to enhance the lung targeting and therapeutic efficacy of semaglutide (SEM). GL-ChMPs were designed to respond to the acidic environment and metalloproteinases, conditions that are typical in pulmonary fibrosis. SEM-GL-ChMPs exhibited superior lung targeting and prolonged retention while minimizing systemic distribution.
