Abstract: Immunotherapy for Alzheimer\''s disease has emerged as a promising approach for clearing pathological tau protein conformers. To explore this kind of treatment we tested an active immunization with pseudo-phosphorylated tau fragments in P301L tangle model mice that develop neuronal tau aggregates as observed in frontotemporal dementia and Alzheimer’s disease. We found that an immunization reduces neurodegeneration in α-motor neurons in the spinal cord and slows progression of the tangle-related behavioral phenotype. Performance on behavioral assays correlated with tau pathology at the corresponding spinal cord level. Interestingly, a slowed progression of these tauopathy related characteristics were only seen in mice that received a specific immunization with pseudo-phosphorylated tau fragments, not in animals that received a non-specific activation of the immune system. An immunization witch pseudo-phosphorylated tau fragments may be a valuable therapeutic option in targeting one of the major hallmarks of Alzheimer’s disease and frontotemporal dementia.
