Simultaneous Live Imaging of Multiple Endogenous Proteins Reveals a Mechanism for Alzheimer’s-Related Plasticity Impairment

？ FingR intrabodies enabled simultaneous live imaging of three endogenous proteins ？ Aβ inhibits CaMKII trafficking after LTP-, but not LTD-inducing, stimuli ？ The Aβ-induced block of CaMKII trafficking requires CaMKII activity ？ Aβ induced internalization of the extrasynaptic, but not synaptic, NMDA recepto
