摘要:
The present invention relates generally to a novel haemopoietin receptor or derivatives thereof and to genetic sequences encoding same. Interaction between the novel receptor of the present invention and a cytokine ligand facilitates proliferation, differentiation and survival of a wide variety of cells. The novel receptor and its derivatives and the genetic sequences encoding same of the present invention are useful in the development of a wide range of agonists, antagonists, therapeutics and diagnostic reagents based on ligand interaction with its receptor.

The present invention relates generally to amino acid sequences obtainable from SOCS proteins and which are capable of interacting with intracellular molecules. The present invention further relates to nucleic acid molecules encoding said amino acid sequences. The amino acid sequences and the nucleic acid molecules encoding same of the present invention are useful in modulating degradation of proteinaceous molecules such as but not limited to SOCS proteins and proteinaceous molecules associate therewith. The present invention provides a mechanism for modulating cytokine or cytokine-like molecule signaling by modulating the degradation of activated signal transduction molecules or their negative regulators, i.e. the SOCS proteins.
摘要:
The present invention relates generally to antibodies that bind to the Interleukin-13 receptor α1 chain (IL-13Rα1) and antagonize IL-13 receptor-mediated signaling by IL-13 and/or IL-4. More particularly, the present invention provides humanized or human antibodies to mammalian and in particular IL-13Rα1. These antibodies have uses in the treatment or prevention of IL-13- and/or IL-4-mediated diseases or conditions. The present invention further contemplates a method of modulating IL-13- and/or IL-4-mediated diseases or conditions by the administration of the subject antibodies. The present invention further provides an assay system useful for identifying antibodies or other agents which modulate IL-13 and/or IL-4 signaling through an IL-13 receptor complex. Accordingly, a method of screening for modulators of IL-13Rα1/ligand interaction is also provided.
摘要:
The present invention relates generally to a method for regulating cytokine signalling and agents useful for same. The method of the present invention is predicated in part on the identification of the molecular target of suppressor of cytokine signalling (SOCS) interaction in controlling cytokine signalling. The identification of the molecular target permits the development of assays to screen for a range of agonists and antagonists useful in modulating cytokine function. The present invention further provides, therefore, screening assays and more particularly high through-put screening assays for agonists and antagonists of SOCS-receptor interaction. Such agonists and antagonists are useful in the manufacture of medicaments for controlling cytokine signalling. Control of cytokine signalling is important for the treatment of a range of conditions including cancer, inflammatory conditions, immunological disorders and any other conditions involving aberrations of signal transduction.

The present invention is directed to a novel haemopoietin receptor or a derivative thereof and to genetic sequences encoding same. The receptor molecule and its derivatives and the genetic sequences encoding same of the present invention are useful in the development of a wide range of agonists, antagonists, therapeutics and diagnostic reagents based on ligand interaction with its receptor. The present invention particularly relates to a receptor for leptin.

The present invention relates generally to therapeutic and diagnostic agents. More particularly, the present invention provides therapeutic molecules capable of modulating signal transduction such as but not limited to cytokine-mediated signal transduction. The molecules of the present invention are useful, therefore, in modulating cellular responsiveness to cytokines as well as other mediators of signal transduction such as endogenous or exogenous molecules, antigens, microbes and microbial products, viruses or components thereof, ions, hormones and parasites.

The present invention relates generally to compounds which modulate cytokine-dependent processes. More particularly, the compounds of the present invention modulate responses to a colony stimulating factor and even more particularly to granulocyte-colony stimulating factor (G-CSF) by modulating the levels of molecules which inhibit G-CSF such as but not limited to a suppressor of cytokine signaling (SOCS) and in particular SOCS-3. The present invention further contemplates methods for regulating G-CSF-dependent processes by contacting cells in vitro with or administering to a subject a compound which up- or down-regulates the level of activity of G-CSF by modulating the level or activity of a SOCS molecule such as SOCS-3. The instant compounds are further useful for modulating a range of G-CSF-induced cellular responses including neutrophil recovery after chemotherapy or radiotherapy, mobilizing stem and progenitor cells, treating infection and treating inflammatory conditions.
摘要:
The present invention relates to the identification of a PEST motif in Suppressor of Cytokine Signalling (SOCS) proteins, the deletion/inactivation of which has been found to increase the stability of the protein whilst maintaining at least one biological activity of the protein. Such SOCS proteins with deleted/inactivated PEST motifs can be used in gene and protein therapy procedures to provide a more stable SOCS protein when compared to the native protein. The present invention also relates to the characterization of the structure of SOCS proteins, and methods of using this structural information to identify compounds which modulate the activity of SOCS.
