Respiratory syncytial virus (RSV)-induced bronchiolitis in infants is not responsive to glucocorticoids. We have recently shown that RSV infection of lung epithelial cells impairs glucocorticoid receptor (GR) function. In this current study, we have shown that the viral mimic poly I:C also represses GR-mediated gene activation in lung epithelial cells, suggesting that this might be a common phenomenon of other viral infections. However, we also show that neither RSV infection nor poly I:C affect GR-mediated gene activation in the monocytic cell line THP-1, suggesting that these effects on GR function may be cell-type specific.

: To explore the clinical value of miR-193a-5p in neonatal acute respiratory distress syndrome (ARDS) and its role in ARDS cell model . : RT-qPCR was utilized to detect miR-193a-5p level. Correlation analysis was implemented to assess the correlation between miR-193a-5p and clinical indicators (IL-6, IL-1β, TNF-α, LUS).

Hedgehog (HH) pathway is involved in pulmonary development and lung homeostasis. It orchestrates airway epithelial cell (AEC) differentiation and contributes to respiratory pathogenesis. The core elements Gli2, Smo, and Shh were found altered in the bronchial epithelium of patients with chronic obstructive pulmonary disease (COPD).

Introduction: Copine-3 (CPNE3) is a conservative calcium-dependent phospholipid-binding protein belonging to the copines protein family. CPNE3 has been implicated in the development and progression of several diseases, including cancer.
Method: Herein, we investigated the molecular mechanisms through which CPNE3 regulates the migration of lung adenocarcinoma (LUAD) cells in vitro.

Host metabolic fitness is a critical determinant of infectious disease outcomes. Obesity, aging, and other related metabolic disorders are recognized as high-risk disease modifiers for respiratory infections, including coronavirus infections, though the underlying mechanisms remain unknown. Our study highlights fatty acid-binding protein 4 (FABP4), a key regulator of metabolic dysfunction and inflammation, as a modulator of SARS-CoV-2 pathogenesis, correlating strongly with disease severity in COVID-19 patients.
