Bleomycin induced pulmonary toxicity and its subpleural onset
2016
Idiopathic Pulmonary Fibrosis (PF) is a rare and devastating disease without efficient treatment at this time. Idiopathic FP is characterized by accumulation of myofibroblasts and has a typical sub-pleural onset suggesting a role of the pleura in the disease. Transforming Growth Factor (TGF)-ß1 induces transformation of pleural mesothelial cells (PMC) into active cells exhibiting myofibroblast phenotype. Heat shock proteins can act as regulator of the TGF-ß1 signaling. A role for caspase-1/IL-1ß axis has already been described in animal models of PF.The heat shock protein AlphaB-crystallin has been studied in PF at the PMC level and the importance of caspase-1/IL-1ß axis has been investigat…

Idiopathic pulmonary fibrosis (IPF) has no effective current treatment. It is characterized by a sub-pleural onset and the presence of myofibroblasts, responsible for the excessive extracellular matrix synthesis. Transforming Growth Factor (TGF)-β1 is considered as the major profibrotic cytokine. Its signaling pathway occurs through the Smads proteins, including Smad4. TGF-β1 allows the differentiation of lung fibroblasts and epithelial and mesothelial cells into myofibroblasts. AB-crystallin is a small heat shock protein overexpressed in liver, renal and vascular fibrosis and can be induced by TGF-β1. In this study, we assessed the role of αB-crystallin in pleural and pulmonary fibrosis. W…
