Abstract: Novel polypeptide combinations, polynucleotides encoding the polypeptides, and related compositions and methods are disclosed for soluble zalpha11 receptors that may be used as novel cytokine antagonists, and within methods for detecting ligands that stimulate the proliferation and/or development of hematopoietic, lymphoid and myeloid cells in vitro and in vivo. Ligand-binding receptor polypeptides can also be used to block zalpha11 Ligand activity in vitro and in vivo, and may be used in conjunction with zalpha11 Ligand and other cytokines to selectively stimulate the immune system. The present invention also includes methods for producing the protein, uses therefor and antibodies thereto.

Abstract: Methods for treating cancer by co-administering a therapeutic monoclonal antibody with IL-21 are described. Exemplary monoclonal antibodies that can be used are rituximab, trastuzumab and anti-CTLA-4 antibodies. The enhanced antitumor of the combination therapy is particularly useful for patient populations that are recalcitrant to monoclonal therapy, relapse after treatment with monoclonal antibodies or where the enhanced IL-21 antitumor effect reduces toxicities associated with treatment using the monoclonal antibodies.

Abstract: This present invention is directed to polypeptide and polynucleotide molecules that encode a four-helical bundle cytokine. The cytokine has been designated zsig81, and has restricted expression in primarily heart, lung and liver. zsig81 has been shown to stimulate proliferation of hematopoietic cells and will be useful expansion of these cells, as well as conditions associated with hematopoietic cells. The invention is directed to antibodies and methods of making zsig81 polypeptides, as well.
