Abstract

Use of antagonists to IL-31 are used to treat inflammation and pain by inhibiting, preventing, reducing, minimizing, limiting or minimizing stimulation in neuronal tissues. Such antagonists include antibodies and fragments, derivative, or variants thereof. Symptoms such as pain, tingle, sensitization, tickle associated with neuropathies are ameliorated.

Claims

1. A method of antagonizing signal transduction in spinal cord cells in a subject, comprising administering to the subject a monoclonal antibody or antigen-binding fragment thereof that specifically binds to a polypeptide sequence of amino acid residues 27-164 of SEQ ID NO:

2, and wherein after administration the signal transduction induced by the polypeptide in the spinal cord cells is reduced.

2. The method of claim 1, wherein the monoclonal antibody or antigen-binding fragment thereof is humanized.

3. The method of claim 1, wherein the antigen-binding fragment thereof is selected from the group consisting of a single-chain antibody, a Fab fragment, a Fab′

fragment, and a F(ab′

)₂ fragment.

4. The method of claim 1, wherein the monoclonal antibody is a chimeric antibody.

5. The method of claim 1, wherein the monoclonal antibody or antigen-binding fragment thereof is produced by the hybridoma selected from the group consisting of:

a) the hybridoma having the ATCC Patent Deposit Designation PTA-6815;

b) the hybridoma having the ATCC Patent Deposit Designation PTA-6816;

c) the hybridoma having the ATCC Patent Deposit Designation PTA-6829;

d) the hybridoma having the ATCC Patent Deposit Designation PTA-6830;

e) the hybridoma having the ATCC Patent Deposit Designation PTA-6831;

f) the hybridoma having the ATCC Patent Deposit Designation PTA-6871;

g) the hybridoma having the ATCC Patent Deposit Designation PTA-6872;

h) the hybridoma having the ATCC Patent Deposit Designation PTA-6875; and

i) the hybridoma having the ATCC Patent Deposit Designation PTA-6873.

6. The method of claim 5, wherein the monoclonal antibody or antigen-binding fragment thereof is humanized.

7. The method of claim 5, wherein the antigen-binding fragment thereof is selected from the group consisting of a single-chain antibody, a Fab fragment, a Fab′

fragment, and a F(ab′

)₂ fragment.
