Research image of tau proteins in the brains of people with Alzheimer’s disease.

Supersized version of Alzheimer’s protein avoids clumping in brain

“Big tau” may explain why some brain regions, such as the cerebellum and brainstem, are largely spared from neurodegeneration, even though tau is expressed throughout the nervous system.

Abstract illustration of antibodies scattered against a peach-colored background.

We found a major flaw in a scientific reagent used in thousands of neuroscience experiments — and we’re trying to fix it.

As part of that ambition, we launched a public-private partnership to systematically evaluate antibodies used to study neurological disease, and we plan to make all the data freely available.
