Methods for treating pain by administering peptides derived from human basic proline-rich lacrimal protein

摘要

The invention relates to an in vitro method for prognosis, diagnosis or determination of the evolution of a condition involving an altered production of Basic Proline-rich Lacrimal Protein (BPLP) or of any of its maturation products, by detecting, or quantifying in a biological sample of a test subject, a BPLP protein or a maturation product thereof, and comparing the production of BPLP protein or maturation product with the production of the same in a biological sample of a control subject.

主权项

1. A method for treating pain comprising administering an effective amount of an isolated peptide consisting of up to 15 amino acids to a human subject,
wherein the peptide comprises the sequence Glu-Arg-Phe-Ser-Arg (SEQ ID NO: 3) or Glp-Arg-Phe-Ser-Arg (SEQ ID NO: 7), wherein the peptide exhibits an inhibitory property against a neutral endopeptidase or an aminopeptidase and wherein the peptide has the same amino acid sequence as that found within human Basic Proline-rich Lacrimal Protein (SEQ ID NO:2) or differs from the amino acid sequence found within SEQ ID NO:2 by two or less amino acid substitutions.
