Tau fragments for immunotherapy
The present invention relates to methods of treating and preventing Alzheimer's Disease or other tauopathies in a subject by administering a tau protein, its immunogenic epitopes, or antibodies recognizing the tau protein or its immunogenic epitopes under conditions effective to treat or prevent Alzheimer's Disease of other tauopathies. Also disclosed are methods of promoting clearance of aggregates from the brain of the subject and of slowing progression of tangle-related behavioral phenotype in a subject.
1. An isolated immunogenic tau peptide consisting of the amino acid sequence of SEQ ID NO:2.
2. The isolated peptide according to claim 1 , wherein the peptide is phosphorylated.
3. The isolated peptide according to claim 1 , wherein the peptide is linked to a promiscuous t-helper cell epitope.
4. A pharmaceutical composition comprising:
the isolated peptide according to claim 1 , a pharmaceutically acceptable adjuvant effective to induce an immune response, and a pharmaceutical carrier.
