摘要:
A method of treating an inflammatory disease is disclosed. The method comprises administering to the subject a therapeutically effective amount of a polypeptide comprising a pro-domain of TNF-alpha converting enzyme (TACE), said polypeptide being devoid of a catalytic domain of said TACE, said polypeptide comprising a modification at a site selected from the group consisting of R58, R56 and K57 which renders said polypeptide resistant to furin degradation said polypeptide being capable of downregulating an activity of TACE, thereby treating the inflammatory disease.
摘要:
The invention relates to a recombinant cell which expresses a substrate protein comprising at least one sequence region of 18 amino acids of the human amyloid precursor protein (APP) or a homologous protein. The sequence region contains the α-secretase cleavage site as well as 6 amino acid rests at the amino terminal and 12 amino acid rests at the carboxy terminal, in relation to the α-secretase cleavage site, and contains either a) a recombinant nucleic acid comprising at least one gene for a protease protein which contains either the sequence region(s), required for proteolytic action, of the disintegrin metalloprotease ADAM 10 obtained from cattle (Bos taurus), humans or another mammal or represents a mutein of a mammalian disintegrin metalloprotease ADAM 10 which has essentially the same enzymatic properties, the gene or genes being controlled by a heterologous promotor; or b) heterologous RNA coding for a substrate protein and a protease protein. The invention also relates to the use of the above cells.
