Novel polypeptides and peptides, nucleic acids encoding them, and their use in the field of tumor therapy, inflammation or immunology

摘要

The invention relates: to a polypeptide containing in its peptidic chain the amino acid sequence of 311 amino acids of FIG. 3, or a fragment of this sequence, with said fragment being such that it is liable to produce antibodies capable of forming a complex with the amino acid sequence of FIG. 3, or an amino acid sequence having a percentage of homology of at least 50%, preferably 75%, and advantageously 90% with the amino acid sequence of FIG. 3, and to pharmaceutical compositions containing, as active substance, at least one of the polypeptides of the invention or of the antagonists of the polypeptides of the invention as antitumor compounds, or antiinflammatory compounds or as growth activators of T-cells and B-cells, as bone repair compounds as inducer of immunosuppressive cells, as inhibitors of anti-colony stimulating factor; or as trypoanocidal agents; or part of the polypeptides of the invention, capable of binding to the above-defined receptor.
