Alzheimer's tau protein has a surprising secret role in memory
Researchers have identified that the tau protein, typically associated with Alzheimer's disease, plays a critical role in stabilizing long-term memories in the brain. The study suggests that while tau is not needed for initial learning, it is essential for the durability of memories over time.
Why it matters
This insight into memory formation could lead to new therapeutic strategies for dementia, focusing on how to preserve the stability of memories in aging populations.
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.
