Stopping the accumulation of abnormal tau protein in the brain holds great potential to delay, slow or prevent Alzheimer’s dementia. The build up of amyloid "plaques" and tau "tangles" in the brain are the two major hallmarks of Alzheimer's disease. Scientists increasingly believe tangles are more closely linked to changes in memory, reasoning and behavior. Normal tau protein stabilizes neurons, but abnormal tau interferes with their structure and function, resulting in brain cell death and subsequent dementia. Toxic tau is also associated with other neurodegenerative disorders, including Parkinson's disease and progressive supranuclear palsy.
Recent research progress is generating exciting new opportunities to develop anti-tau therapies. Laboratory researchers are making great strides in identifying biological pathways that cause tau to accumulate. At the same time, the recent development of tau PET brain imaging is enabling clinical researchers to track the deposition of tau in the brains of living individuals and to determine how it is associated with cognitive decline. These advances are providing — for the first time — the foundation for the development and testing of innovative drug targets, pharmacological agents and other therapeutic strategies for tauopathies.
The Alzheimer's Association has launched a new funding initiative to accelerate the translation of tau research breakthroughs from "bench to bedside." There is a considerable gap between academic researchers and pharmaceutical companies that are looking for drug candidates to be taken into human trials. To bridge this gap, the Alzheimer's Association is partnering with the Rainwater Charitable Foundation to enable researchers to devise innovative clinical treatments that prevent, reduce, remove or otherwise mitigate the toxic effects of tau build-up. Grants awarded through the Tau Pipeline Enabling Program (T-PEP) aim to shorten the timeline from discoveries in the laboratory to clinical studies that evaluate their potential as effective treatments stop or slow disease progression.
TThe Alzheimer's Association is funding five multi-year research grants.. Each dollar provided by the Association, up to $1.5 million, is being matched by the Rainwater Charitable Foundation, leveraging our commitment to further advance promising new therapies through T-PEP.
