Synapses are specialized cellular junctions essential for communication between neurons. Synapse loss occurs in many neurodegenerative diseases. Harnessing our molecular knowledge of the development and maintenance of synapses, Suzuki et al. present the first comprehensive attempt to use a synthetic protein to bridge the pre- and postsynaptic membranes¹. They show that this powerful approach can stimulate the formation of pre- and postsynaptic specializations in vitro, rescue synaptic deficits of mutant mice in vivo, and ameliorate synapse loss and behavioral abnormalities in both Alzheimer's disease and spinal cord injury mouse models.
