Human tau seeds trigger disease-specific shapes in mouse brains, new study finds

Tau is a protein that occurs naturally in the brain. It is essential for proper neuron development and for how neurons communicate with each other. The same protein, however, when misshapen or misfolded, can act as a driver of neurodegenerative diseases. Abnormal buildup of tau is a hallmark of Alzheimer's disease, and scientists have also found an association between misfolded tau and more than 20 neurodegenerative diseases.
