Congratulations, Sarah Shapley on her first author manuscript published this month! In collaboration with Dr. Stacey Rizzo’s team at the University of Pittsburgh, we investigated the presence of tau in marmoset brains to establish the foundational translatability of this animal model to human disease. Tau was not only present in adult marmoset brains, but also found to be at a ~40%:60% ratio of 3R:4R.
