Toxic and idiopathic pulmonary fibrosis (PF) start classically in the subpleural area. It is known that 1) pleural mesothelial cells (PMCs) acquire a TGF-beta1-induced myofibroblast phenotype and 2) inflammation plays a significant role in fibrogenesis. The role of mesothelial cells in PF and in bleomycin lung toxicity has still to be investigated.C57Bl/6 mice were intravenously injected with bleomycin or NaCl. Repeated intravenous bleomycin induces a peculiar lung fibrotic response with 1) an histological peripheral distribution, 2) a collagen accumulation in pleural and subpleural area, 3) an overexpression of MMP-2, -9, HSP27, all involved in PMCs transformation and 4) a migration of PMCs into the lung.... %G English %L hal-01512935 %U https://u-bourgogne.hal.science/hal-01512935 %~ UNIV-BOURGOGNE %~ LNC-UMR866 %~ AGREENIUM %~ AGROSUP-DIJON %~ ENSBANA
