Methods and compositions for improved cognition
View Patent ↗Provided herein are klotho polypeptide compositions and methods for improving cognitive function in an individual comprising treatment of with klotho polypeptides.
1. A method of treating cognitive decline in an individual having a mental or mood disorder, comprising administering systemically to the individual an effective amount of a recombinant polypeptide comprising an amino acid sequence having at least 95% identity to the sequence of amino acids 34-979 of SEQ ID NO:1, with the proviso that the polypeptide is not a FGF fusion protein.
2. The method of claim 1 , wherein the individual's mental or mood disorder is depression, schizophrenia, attention deficit/hyperactivity disorder, autism spectrum disorder, or intellectual disability.
3. The method of claim 2 , wherein the individual's mental or mood disorder is depression.
4. The method of claim 2 , wherein the individual's mental or mood disorder is schizophrenia.
5. The method of claim 2 , wherein the individual's mental or mood disorder is attention deficit/hyperactivity disorder.
6. The method of claim 2 , wherein the individual's mental or mood disorder is autism spectrum disorder.
7. The method of claim 2 , wherein the individual's mental or mood disorder is intellectual disability.
8. The method of claim 1 , wherein the amino acid sequence is at least 99% identical to amino acids 34-979 of SEQ ID NO:1.
9. The method of claim 1 , wherein the amino acid sequence comprises amino acids 34-979 of SEQ ID NO:1.
10. The method of claim 1 , comprising:
determining cognitive function in the subject before administration of the polypeptide,
determining cognitive function in the subject following systemic administration of the polypeptide, and
comparing the cognitive function in the subject before administration of the klotho to the cognitive function of the subject following administration of the polypeptide.
11. The method of claim 1 , wherein the polypeptide is administered to the subject intravenously.
