Tau is a protein best known for forming toxic tangles in Alzheimer disease. It also drives faulty brain wiring in childhood conditions, including brain injury from oxygen and blood-flow loss around birth (hypoxic-ischemic injury) and its common later effects, epilepsy and autism.

What they work on

  1. Determine whether tau's interaction with NMDA receptors, signaling channels at nerve connections, is needed for human neurons to mature and grow dendrites, using tau knockout human neurons.
  2. Test the role of human tau's unique N-terminal insert in neurodevelopment, including its interaction with fyn kinase, an enzyme that boosts NMDA receptor signaling.
  3. Define a normal, human-specific developmental function of tau to help set a safe window for tau-reducing therapies in neurodevelopmental disorders.

More about the research

Drugs that lower tau levels have been developed for Alzheimer disease and are safe in adults. They could perhaps be adapted for these developmental disorders. But tau has been preserved across all mammals, which suggests it does something useful. Before tau-lowering drugs can safely be given to a developing brain, researchers need to know what tau normally does there.

Why it matters

Children with epilepsy, autism or early-life hypoxic-ischemic brain injury might one day benefit from tau-lowering drugs first developed for Alzheimer disease. Knowing whether tau is needed for normal brain development would help define when reducing tau is safe. This knowledge is needed before such therapies could move forward for these lifelong conditions.
