    摘要: Methods of activating a signaling cascade comprising, introducing leptin and/or a cytokine to a receptor complex comprising gp 130, optionally in combination with a compound acting on adenylate cyclase or acting on one or more downstream targets of adenylate cyclase, thereby inducing genes in neuro-endocrine cells or cells of neuro-endocrine origin. Two distinct gene-sets are induced, immediate early response genes (STAT-3, SOCS-3, Metallothionein-II, the serine/threonine kinase Fnk and the rat homologue of MRF-1), and late induced target genes (Pancreatitis Associated Protein I, Squalene Epoxidase, Uridinediphosphate Glucuronyl Transferase and Annexin VIII). Strong co-stimulation with the adenylate cyclase activator forskolin was shown with respect to late induced target genes. Transcripts encoding Leptin Induced Protein I (LIP-I) and Leptin Induced Protein II (LIP-II) were identified; however, no forskolin co-stimulatory effect was observed. It is also demonstrated that leptin modulates in vivo expression of MT-II, Fnk and Pancreatitis Associated Protein I genes.

    摘要: It is an object of this invention to provide a human Tumor Necrosis Factor mutein or a pharmaceutically acceptable salt thereof characterized in that the TNF sequence is changed by a deletion, insertion, substitution or combinations thereof, of one or more amino acids so that the mutein shows a significant difference between its binding affinity to the human p75-Tumor-Necrosis-Factor-Receptor and to the human p55-Tumor-Necrosis-Factor-Receptor. The invention also includes DNA sequences coding for such muteins, vectors comprising such DNA sequences, host cells transformed with such vectors and a process for the production of such muteins employing such transformed host cells and pharmaceutical compositions containing such muteins and their use for the treatment of illnesses, for example cancer.

    摘要: The invention relates to a recombinant receptor, comprising a ligand-binding domain and a signaling domain that comprises a heterologous bait polypeptide, which receptor is inactivated by binding of a prey polypeptide to the heterologous bait peptide, either in presence or absence of a ligand binding to the ligand-binding domain. The receptor is activated by addition of a compound that disrupts the bait-prey interaction. The invention also relates to a method of screening compounds that disrupt compound-compound binding using the recombinant receptor.

    摘要: The present invention relates to an antagonist or inhibitor of leptin signaling via the leptin receptor. The leptin antagonist binds to the leptin receptor, but is unable to induce JAK-STAT signal transduction via the leptin receptor. By binding to the leptin receptor, the leptin antagonist impairs binding of leptin to the leptin receptor and blocks leptin signaling.
