    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.

    摘要: The present invention relates generally to a method for modulating cell survival. Modulation of cell survival includes inducing, enhancing or otherwise promoting cell survival such as the survival of neural cells as well as facilitating cell death such as the death of targeted cancer cells. The modulation of cell survival is mediated by a region identified on the p75 neurotrophin receptor (p75NTR) required for death signalling. The present invention further provides genetic molecules which encode the death signalling region of p75NTR which are useful in antagonising death signal function as well as promoting cell death when expressed in targeted cells. The present invention also contemplates recombinant peptides, polypeptides and proteins s well as chemical equivalents, derivatives and homologues thereof which comprise the death signalling portion of p75NTR. Particularly useful molecules of the present invention comprise peptides corresponding to soluble forms of the death signalling portion of p75NTR. These molecules antagonise p75NTR-mediated cell death.

    摘要: The present invention relates generally to antibodies that bind to the Interleukin-13 receptor.alpha.1 chain (IL-13R.alpha.1) 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-13R.alpha.1. 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-13R.alpha.1/ligand interaction is also provided.
