Aged mutant amyloid
precursor protein mice with established disease showed a near complete restoration in levels of synaptic and neuronal proteins after exposure to young blood in parabiosis (synaptophysin P =.02; calbindin P =.02) or following intravenous plasma administration (synaptophysin P <.001; calbindin P =.14).
