Analysis of vesicular trafficking in primary neurons by live imaging.
Alzheimer's disease, the most common neurodegenerative disease, is characterized by a progressive loss of synapses and accumulation of amyloid-beta (Aβ) peptides in the brain. Previous studies demonstrated that acute increase in synaptic activity in cultured hippocampal slices and mouse brains (Cirrito et al. Neuron 48: 913-922, 2005; Kamenetz et al. Neuron 37: 925-937, 2003) enhanced secretion of
