Abstract: 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.

Abstract: The present invention relates generally to a biologically active complex comprising at least two heterologous molecules. More particularly, the biologically active complex of the present invention comprises at least two polypeptides or parts, fragments, truncates or protease-activated forms of one or more of the polypeptides wherein the complex alone or in association with a receptor, ligand or other molecule facilitates proliferation, differentiation and/or survival of a cell. The identification of the biologically active complex of the present invention permits the assay for agonists and antagonists of the formation of the biologically active complex as well as therapeutic and diagnostic reagents based on the biologically active complex or interaction between the biologically active complex and a receptor, ligand or other molecule.

Abstract: The present invention relates to the use of leukemia inhibitory factor (LIF) in the isolation and propagation of embryonic stem cells in vitro.

Abstract: The present invention relates to a method for regulating neuron development/maintenance and/or regeneration in a nervous system of a mammal and to pharmaceutical compositions comprising leukaemia inhibitory factor useful for same.
