Background: Pulmonary fibrosis is a progressive disease with high incidence and poor prognosis. It is urgent to explore new therapeutic methods for pulmonary fibrosis. As a new treatment method, gene therapy has attracted more and more attention. CCDC59 is a transcriptional coactivator of SP-B and SP-C. Our study mainly aims to explore the effect of overexpression of CCDC59 gene in pulmonary fibrosis of mice.
Methods: CCDC59 overexpressing lentivirus was constructed and then concentrated. RT-qPCR, Western blotting, and immunofluorescence assays were used to detect the expression of CCDC59, SP-B and SP-C protein in cell line and lung tissues after infected with lentivirus. Immunohistochemical staining and hematoxylin-eosin staining assays were used to assess the degree of fibrosis and ELISA assay was used to detect the concentrations of inflammatory factors, SP-B, and SP-C in bronchoalveolar lavage fluid of mice. Dynamic changes of mice lung function at various time points were assessed by lung function test assay. HIPPO pathway and proliferation capacity of alveolar type II epithelial cells were evaluated by immunofluorescence staining and Western blotting.
Results: Results showed that endotracheal instillation of CCDC59 overexpressed lentivirus significantly alleviated bleomycin-induced inflammation and pulmonary fibrosis in mice. Overexpression of CCDC59 protein in type II alveolar epithelial cells can enhance the expression of SP-B and SP-C. Overexpression of CCDC59 protein significantly protected against pulmonary inflammatory response and improved lung function of mice. Overexpression of CCDC59 protein significantly alleviated the hyperactivation of HIPPO pathway and increased the proliferative capacity of type II alveolar epithelial cells in lung.
Conclusion: CCDC59 can alleviate inflammation and pulmonary fibrosis in mice by upregulating the expression of SP-B and SP-C in type II alveolar epithelial cells and alleviating the hyperactivation of HIPPO pathway. Our study offers a new potential treatment for pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a severe and progressive lung disorder with an average survival rate of 3 to 5 years. IPF presents a significant challenge in clinical management, necessitating novel therapeutic approaches. Nanostructured lipid carriers (NLCs) have proven to be promising vehicles for targeted drug delivery to the lung tissues.

Pulmonary ionocytes express high levels of cystic fibrosis transmembrane conductance regulator (CFTR) channels. When studied using the short-circuit current technique, ionocytes produce CFTR-dependent short-circuit currents consistent with Cl secretion. However, when studied without a voltage-clamp, data indicate that ionocytes absorb Cl.

BACKGROUND Acute respiratory distress syndrome (ARDS) due to coronavirus 2019 (COVID-19) can result in severe disease requiring mechanical ventilatory support. A subset of these patients, however, demonstrate refractory hypoxemia/hypercarbia requiring veno-venous extracorporeal membrane oxygenation (V-V ECMO) as adjunctive therapy. The primary goal of V-V ECMO is a "bridge" to recovery of native lung function; however, patients may progress to irreversible pulmonary damage requiring lung transplantation.

Background: Nutritional support for people with cystic fibrosis (PwCF) after the implementation of novel drug therapies is shifting from managing malnutrition through a high-fat, high-calorie diet to managing emerging incidences of obesity in this population. Additionally, dietary recommendations prescribed with elexacaftor/tezacaftor/ivacaftor (ETI) recommend taking this drug with a fat-containing meal, which is variably interpreted by patients. This pilot and feasibility study was conducted to assess dietary fat intake and body composition on ETI plasma concentrations.

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), causes acute coronavirus disease-19 (COVID-19) that has emerged on a pandemic level. Coronaviruses are well-known to have a negative impact on the lungs and cardiovascular system. SARS-CoV-2 induces a cytokine storm that primarily targets the lungs, causing widespread clinical disorders, including COVID-19.
