Tau black tangles and amyloid beta in the brain of a 57-year-old chimpanzee. The co-occurrence of these two proteins is a hallmark of Alzheimer's disease in humans. The tau-positive neuron in the center (black) is at the pretangle/tangle stage. The amyloid beta deposits are present in nearby blood vessels (red).
