IL-31 monoclonal antibodies
The present invention relates to methods of treating pruritic diseases, including but not limited to Contact dermatitis, Atopic Dermatitis, Drug induced delayed type cutaneous allergic reactions, Toxic epidermal necrolysis, Cutaneous T cell Lymphoma, Bullous pemphigoid, Alopecia wereata, Vitiligo, Acne Rosacea, Prurigo nodularis, Scleroderma, Herpes simplex virus, or combination thereof by administering IL-31 monoclonal antibodies. The invention further provides the hybridomas that generate the monoclonal antibodies.
1. An isolated monoclonal antibody or antigen-binding fragment thereof that specifically binds to a polypeptide consisting of amino acid residues 27-164 of SEQ ID NO:2, wherein the monoclonal antibody or antigen-binding fragment binds to the same epitope as the antibody produced by the hybridoma deposited with the American Type Culture Collection (ATCC) having the ATCC Patent Deposit Designation PTA-6815.
2. The monoclonal antibody or antigen-binding fragment of claim 1 , wherein the monoclonal antibody or antigen-binding fragment neutralizes the signal transduction of the polypeptide through its cognate receptor.
3. The monoclonal antibody or antigen-binding fragment of claim 1 , wherein the monoclonal antibody or antigen-binding fragment further comprises a radionuclide, enzyme, substrate, cofactor, fluorescent marker, chemiluminescent marker, peptide tag, magnetic particle, or toxin.
4. The monoclonal antibody or antigen-binding fragment of claim 1 , wherein the monoclonal antibody or antigen-binding fragment is conjugated to a polyethylene glycol.
5. The monoclonal antibody or antigen-binding fragment of claim 1 , wherein the monoclonal antibody or antigen-binding fragment is chimeric.
6. The monoclonal antibody or antigen-binding fragment of claim 1 , wherein the monoclonal antibody or antigen-binding fragment is humanized.
7. The monoclonal antibody or antigen-binding fragment of claim 1 , wherein the antigen-binding fragment is a Fab or a F(ab′) 2 .
