Idiopathic pulmonary fibrosis is a chronic inflammatory lung disease with interstitial fibrosis. As a potent proinflammatory cytokine, TNF has been suggested to play critical roles in the pathogenesis of the human disease and its animal model, bleomycin-induced pneumopathy. However, studies using TNF-deficient mice have demonstrated that TNF also has an anti-inflammatory function. To determine ...

Pulmonary fibrosis is a chronic condition characterized by progressive scarring of lung parenchyma. The aim of this study was to examine the effects of an ultramicronized preparation of palmitoylethanolamide (PEA-um(®)), an endogenous fatty acid amide, in mice subjected to idiopathic pulmonary fibrosis. Idiopathic pulmonary fibrosis was induced in male mice by a single intratracheal administrat...

A similar immune response is implicated in the pathogenesis of pulmonary fibrosis and allergic disorders. We investigated the potential therapeutic efficacy and mechanism of rupatadine, a dual antagonist of histamine and platelet-activation factor (PAF), in bleomycin- (BLM-) and silica-induced pulmonary fibrosis. The indicated dosages of rupatadine were administered in rodents with bleomycin or...

Coronavirus disease 2019 (COVID-19) has caused nearly 15 million deaths worldwide. The rapid development of COVID-19 vaccines and anti-viral drugs significantly decreased the level mortality related to COVID-19. However, post-COVID-19 pulmonary fibrosis become a severe problem for some patients. previous articles present results mesenchymal stem cell (MSC) transplantation treat patients; in thi...

BACKGROUND Therapy-induced inflammation and progressive fibrosis limit the efficacy of thoracic radiotherapy for lung neoplasms. However, mice bearing a null mutation of intercellular adhesion molecule 1 (ICAM-1) have previously been found to display no inflammatory cell infiltration into the lung following thoracic irradiation. We investigated the role of ICAM-1-mediated inflammation in the pa...

The molecular mechanisms of pulmonary fibrosis are poorly understood. Previous reports indicate that activation of TGF-beta1 is essential for the development of pulmonary fibrosis. Here, we report that the proapoptotic Bcl-2 family member Bid is required for the development of pulmonary fibrosis after the intratracheal instillation of bleomycin. Mice lacking Bid exhibited significantly less pul...

The pulmonary endothelin (ET) system has been implicated in the pathogenesis of chronic lung diseases such as pulmonary hypertension, asthma, chronic obstructive lung disease, idiopathic pulmonary fibrosis, and bronchiolitis obliterans. However, the etiologic role of ET-1 in these diseases has not yet been established. We recently demonstrated that ET-1 transgenic mice, generated using the huma...

Idiopathic Pulmonary Fibrosis is a chronic lung disease characterized by lung inflammation and progression to fibrosis. Anti-fibrotic efficacy of lutein was studied in mouse model of bleomycin induced pulmonary fibrosis. The mice were orally administrated with 100 or 200 mg/kg of lutein three days prior to intra-tracheal instillation of bleomycin on day 0 and continued up to day 21. Total cell ...

Pulmonary fibrosis refers to a group of lung diseases characterized by inflammation, fibroblast proliferation, and excessive collagen deposition. Although the mechanisms underlying pulmonary fibrosis are poorly understood, current evidence suggests that epithelial injury contributes to the development of fibrosis. Regenerative medicine approaches using extracellular matrix (ECM) scaffolds have ...

A number of studies have previously provided evidence on the Anti-inflammatory properties of plant-derived compounds that can prevent lung injury. In this study, we attempted to analyze the therapeutic effects of PM 014 on inflammation and pulmonary fibrosis in COVID-19 as well as describing the treatment of one of the most challenging problems related to the coronavirus-19 (COVID-19). We belie...
