New research has revealed that tau, a protein best known for its connection to Alzheimer's disease, is also essential for creating long lasting memories. The discovery provides new insight into how healthy memory works and could help guide future efforts to develop treatments for dementia.
The study, led by Flinders University in partnership with researchers from the University of New South Wales and Macquarie University, was published in Nature Communications. It found that tau helps organize and stabilize memories so they can be retained over time.
The researchers studied "remote memory" in mice, which refers to memories recalled days or weeks after an experience. They discovered that tau is not necessary for learning something new or remembering it shortly afterward. Instead, it plays a crucial role in making those memories durable over the long term.
Because the research was conducted in mice, the findings cannot be directly applied to human memory or Alzheimer's disease. Even so, the results offer valuable clues that could shape future dementia research and treatment strategies.
