Patent ID: 10471119

Abstract:
A method of preventing or treating neurological disease includes administering to a subject in need thereof, a composition comprising an osmotin peptide selected from the group consisting of (a) an osmotin peptide having the amino acid sequence of SEQ ID NO: 1, and (b) an osmotin peptide having at least one amino acid residue substitution, deletion or insertion in the amino acid sequence of SEQ ID NO: 1. When a subject is treated with the osmotin peptide, nerve cells show no increase in growth rate, have little cytotoxicity, and suppress cell death, and when the osmotin peptide is administered to an animal model, the osmotin peptide infiltrated into the hippocampus of the brain and the hypothalamus of the brain, which is the deep part of the brain. Accordingly, the osmotin peptide is used as a composition for preventing, ameliorating, or treating neurological disease.
