Insulin-like growth factor-I (IGF-I) has been implicated in postnatal alveolar development, pulmonary fibrosis, and non-small cell lung cancer. To further investigate the role of IGF-I, we created a line of transgenic mice in which alveolar type II epithelial cells express human IGF-IA under the control of the surfactant protein C promoter. We determined the effect of pulmonary overexpression o...

Pulmonary toxicity, including fibrosis, is a serious adverse effect associated with the antidysrhythmic drug amiodarone (AM). We tested the potential usefulness of pirfenidone against AM-induced pulmonary toxicity in the hamster model. Intratracheal AM administration resulted in pulmonary fibrosis 21 days posttreatment, as evidenced by an increased hydroxyproline content and histological damage...

Oncostatin M (OSM), an IL-6 family cytokine, has been implicated in a number of biological processes including the induction of inflammation and the modulation of extracellular matrix. In this study, we demonstrate that OSM is up-regulated in the bronchoalveolar lavage fluid of patients with idiopathic pulmonary fibrosis and scleroderma, and investigate the pathological consequences of excess O...

BACKGROUND Naja naja atra venom (NNAV) displays diverse pharmacological actions including analgesia, anti-inflammation and immune regulation.In this study, we investigated the effects of NNAV on pulmonary fibrosis and its mechanisms of action. METHODS To determine if Naja naja atra venom (NNAV) can produce beneficial effects on pulmonary fibrosis, two marine models of pulmonary fibrosis were ...

Idiopathic pulmonary fibrosis (IPF) exhibits a complex and poorly understood pathogenesis. Overt inflammation in the lungs of patients with established IPF is absent, and classic anti-inflammatory therapies are inefficacious; however, inflammation may contribute to the disruption of the normal alveolar architecture, allowing interaction between fibroblasts and the epithelium. The polarisation o...

Chronic inflammation of the lungs is a major cause morbidity and mortality in patients with cystic fibrosis. One macrolides, azithromycin has antimicrobial, immunomodulatory, anti-inflammatory effects that are useful diseases chronic inflammatory processes such as This systematic review aimed to determine efficacy safety administration for fibrosis improving lung function. Pulmonary function wa...

Idiopathic pulmonary fibrosis (IPF) is a disease with a poor prognosis and very few available treatment options. The involvement of the purinergic receptor subtypes P2Y2 and P2X7 in fibrotic lung disease has been demonstrated recently. In this study, we investigated the role of P2Y6 receptors in the pathogenesis of IPF in humans and in the animal model of bleomycin-induced lung injury. P2Y6R ex...

BACKGROUND Pulmonary fibrosis is an untreatable, fatal disease characterized by excess deposition of extracellular matrix and inflammation. Although the etiology of pulmonary fibrosis is unknown, recent studies have implicated dysregulated immune responses and wound healing. Since n-3 polyunsaturated fatty acids (n-3 PUFAs) may beneficially modulate immune responses in a variety of inflammatory...

Idiopathic pulmonary fibrosis (IPF) is a chronic devastating disease with poor prognosis. Multiple pathological processes, including inflammation, epithelial mesenchymal transition (EMT), apoptosis, and oxidative stress, are involved in the pathogenesis of IPF. Recent findings suggested that nuclear factor-κB (NF-κB) is constitutively activated in IPF and acts as a central regulator in the path...

Introduction: Edema and collagen deposition are processes involved in the inflammatory response, which are fundamental to wound-healing [1]. Despite their diverse symptoms and etiologies, asthma and chronic obstructive pulmonary disease, as well as many other forms of pulmonary pathologies, share the common features of airways remodeling and excess collagen deposition [2]. The mechanisms behind...
