In this study chronic oral administration of the TrkB agonist 7,8-DHF activated TrkB signaling and prevented Aβ deposition in transgenic mice that coexpress five familial Alzheimer's disease mutations (5XFAD mice). Moreover, 7,8-DHF inhibited the loss of hippocampal synapses, restored synapse number and synaptic plasticity, and prevented memory deficits. These results suggest that 7,8-DHF represents a novel oral bioactive therapeutic agent for treating AD.
