■Synaptogenesis molecule Cbln1 is secreted from the lysosomes of neuronal activity-dependent manner granule cell axons（Neuron）2019.5.7

Lysosomes is、A cell organelles with enzymes that break down proteins、It plays a decomposition of no longer needed intracellular protein。Protein Cbln1 with new produce work the synapse by the present study was found to be present in the lysosome in the axons of nerve cells。Also, when the neural activity is enhanced、The contents of the lysosomes from axons that (a proteolytic enzyme and Cbln1) are both secreted out of the cells was found for the first time。From these experimental results、Proteolytic enzyme by disruption of the extracellular environment (scrap) and synapse formation by Cbln1 (build) is、By working in concert、Possibility that the restructuring takes place in the synapse in response to neural activity is suggested。Synaptic reorganization is an entity of memory and learning、The failure have been reported in a number of mental illnesses and neurodevelopmental disorder、The results of this research are expected to lead to the development of understanding and new treatments for the normal development mechanism and these conditions。
