1 Plasmin regulates the activation of cell-associated latent TGF-beta 1 secreted by rat alveolar macrophages after in vivo bleomycin injury. Bleomycin transforming growth factor, beta 1 Rattus norvegicus
2 In a model of pulmonary inflammation and fibrosis induced by the antineoplastic antibiotic, bleomycin, we have demonstrated that explanted alveolar macrophages secrete progressively increasing quantities of a biologically active form of TGF-beta 1, the secretion of which was maximal 7 days after bleomycin administration. Bleomycin transforming growth factor, beta 1 Rattus norvegicus
3 In a model of pulmonary inflammation and fibrosis induced by the antineoplastic antibiotic, bleomycin, we have demonstrated that explanted alveolar macrophages secrete progressively increasing quantities of a biologically active form of TGF-beta 1, the secretion of which was maximal 7 days after bleomycin administration. Bleomycin transforming growth factor, beta 1 Rattus norvegicus
4 Because the diminution of active TGF-beta 1 coincides with the resolution of inflammation, this suggests that the availability of plasmin regulates the biologically active form of TGF-beta 1, and thus, the inflammation seen after bleomycin-induced lung injury. Bleomycin transforming growth factor, beta 1 Rattus norvegicus
