A protein called transforming growth factor-beta (TGF-.beta.) is important in causing the inflammation and progressive scar tissue in pulmonary fibrosis. The TGF-.beta.1 isoform is important in the pathogenesis of pulmonary fibrosis. It is usually secreted non-covalently bound to a latency associated peptide (LAP) which renders it biologically inactive. The inactive form is called latent TGF-.beta.1 (L-TGF-.beta.1). Activation of L-TGF-.beta.1 involves L-TGF-.beta.1/TSP-1 complex which interacts with the TSP-1 receptor, CD36, to process L-TGF-.beta.1 to the mature form in the presence of plasmin. Synthetic or natural CD36 peptides or fragments thereof can be used to prevent activation of TGF-.beta.1 in mammalian alveolar macrophages, thereby controlling the inflammation process.

Une protéine dénommée facteur de croissance transformant bêta¿1? (TGF.beta.¿1?) joue un rôle important dans l'inflammation et la formation progressive de tissu cicatriciel en cas de fibrose pulmonaire. L'isoforme de TGF.beta.¿1? s'avère d'importance dans la pathogénie d'une fibrose pulmonaire. Elle est, d'ordinaire, sécrétée en étant lié de manière non covalente à un peptide associé à latence (LAP), ce qui la rend biologiquement inactive. Cette forme inactive est appelée TGF.beta.¿1? latent (L-TGF.beta.¿1?). L'activation de L- TGF.beta.¿1? fait intervenir un complexe, L-TGF.beta.¿1?/TSP-1, lequel interagit avec le récepteur de TSP-1, CD36, pour amener à maturation le L-TGF.beta.¿1? en présence de plasmine. Il est possible d'utiliser des peptides CD36, synthétiques ou d'origine naturelle, ou des fragments de ceux-ci, en vue d'empêcher une activation de TGF.beta.¿1? et, partant, de lutter contre le processus inflammatoire.
