Abstract: The present invention relates to recombinant chimeric proteins comprising a surfactant protein precursor N-terminally fused to a plasminogen activator or comprising a mature surfactant protein N-terminally or C-terminally fused to a plasminogen activator. The invention is also directed to the corresponding nucleic acid molecules encoding such fusion proteins as well as to a method for their production. The invention further refers to a pharmaceutical composition comprising such a fusion protein and to pharmacological uses of an inventive fusion protein for the prevention and/or treatment of inflammatory and interstitial lung diseases.

Abstract: Mature alveolar surfactant protein B and a process for producing the same is disclosed. The process includes the use of a fusion protein of SP-B having a propeptide only at its amino terminus. A propeptide at its carboxyl terminus is not necessary, and thus not included in the fusion protein, to produce the mature SP-B of this process. Cleavage of the amino-terminus propeptide results in the production of mature SP-B.
