Project Snapshot

Alzheimer's disease is the most common cause of dementia, accounting for 60-70% of all cases. Current Alzheimer’s disease medications only alleviate symptoms and do not modify the underlying mechanisms that cause the disease. Consequently, finding an effective therapeutic for Alzheimer’s disease is of critical importance. One major contributor to the spread of Alzheimer’s disease within the brain is the transmission of abnormal forms of a protein called tau. In this process, abnormal tau is released from diseased brain cells and taken up by neighbouring healthy brain cells, triggering the misfolding of the normal tau inside those cells. Thus, Alzheimer’s disease progressively spreads throughout the brain. Nanoparticles are tiny balls that can be engineered to package drugs and deliver them precisely to diseased tissue inside a patient, thus enhancing a drug treatment’s efficacy and improving the outcomes of patients. This project aims to harness the properties of unique nanoparticles found inside bacteria by re-engineering them into a novel nanotechnology that can be utilised to treat dementia. These naturally-occurring nanoparticles will be altered into tiny drug carriers that selectively target and disrupt tau pathology, halting the progression Alzheimer’s disease inside the brain. To reach this goal, I will combine a set of novel tools and techniques found in protein engineering, drug delivery, pharmacology and neurobiology. This research has the potential to provide a disease-modifying treatment that would be of significant benefit to the millions of individuals living with Alzheimer’s disease.
