Antibodies that bind to polypeptides and peptides comprising the sequence of zalpha11 Ligand as shown in SEQ ID NO: 2 are described. The antibodies may bind the full length sequence of 162 amino acid residues or a fragment thereof, including a mature polypeptide of 131 amino acid residues and smaller polypeptide and peptide sequences. The antibodies may include antibodies that are polyclonal, monoclonal, murine, humanized or neutralizing. Methods for producing the antibodies are also described.

Cytokine zalpha11 ligand antibodies and methods of use

Methods for treating mammals with infections, particularly viral infections using molecules that have an IL-21 functional activity are described. The molecules having IL-21 functional activities include polypeptides that have homology to the human IL-21 polypeptide sequence and proteins fused to a polypeptide with IL-21 functional activity. The molecules can be used as a monotherapy or in combination with other known antimicrobial or antiviral therapeutics.

Method for expanding hematopoietic cells using cytokine zalpha11 ligand

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.

Zalpha11 cytokine receptors

The present invention relates to zalpha11 Ligand polynucleotide and polypeptide molecules. The zalpha11 Ligand is a novel cytokine. The polypeptides may be used within methods for stimulating the proliferation and/or development of hematopoietic cells in vitro and in vivo. The present invention also includes methods for producing the protein, uses therefor and antibodies thereto.
