Abstract

The disclosure provides polypeptides and pharmaceutical compositions thereof. Such polypeptides can be useful, for example, in treating pain in a subject. In some embodiments, the polypeptides are useful for treating neuropathic and/or inflammatory pain.

Claims (13)

1. A method of treating pain in a subject in need thereof, the method comprising administering to the subject a therapeutically effective amount of a polypeptide having the amino acid sequence shown in to SEQ ID NO: 2, or a pharmaceutical composition thereof.

2. The method of claim 1 , wherein administration of the polypeptide or a pharmaceutical composition thereof increases glutamate delta 1 receptor (GluD1)-cerebellin 1 (Cbln1) signaling.

3. A method of increasing GluD1-Cbln1 signaling in a subject in need thereof, the method comprising administering to the subject a polypeptide having the amino acid sequence shown in SEQ ID NO:2, or a pharmaceutical composition thereof.

4. The method of claim 1 , wherein the pain comprises neuropathic pain.

5. The method of claim 4 , wherein the neuropathic pain is associated with nerve compression, nerve damage, abnormal processing of pain signals, or a combination thereof.

6. The method of claim 4 , wherein the neuropathic pain is a side effect of a therapeutic agent.

7. The method of claim 6 , wherein the therapeutic agent is a chemotherapy.

8. The method of claim 7 , wherein the chemotherapy comprises a taxane, a platinum-based agent, a vinca alkaloid, an epothilone, eribulin, bortezomib, thalidomide, or a combination thereof.

9. The method of claim 1 , wherein the subject has chemotherapy-induced neuropathic pain.

10. The method of claim 1 , wherein the pain comprises inflammatory pain.

11. The method of claim 10 , wherein the inflammatory pain is associated with surgery, trauma, arthritis, or a combination thereof.

12. The method of claim 1 , wherein the polypeptide or a pharmaceutical composition thereof is administered to the central nervous system of the subject.

13. A method of reducing an amount of opioid administered to a subject, the method comprising administering to the subject a therapeutically effective amount of a polypeptide having the amino acid sequence shown in SEQ ID NO: 2, or a pharmaceutical composition thereof.
