| Research Abstract |
In this study, we examined the functional role of a D-serine highly existing in the developing cerebella. D-Serine in the cerebellum, which was released from glial cells in a neuronal activity-dependent manner, bound to the postsynaptically-expressing delta2-type ionotropic glutamate receptors (delta2 receptors) to regulate synaptic plasticity, a molecular basis of learning and memory. Interestingly, we revealed that delta2 receptor controlled the synaptic plasticity by binding to the tyrosine phosphatase PTPMEG via its intracellular C-terminus. Thus, D-serine-delta2 signaling is a unique D-serine signaling, which may gain new insights into the glia-neuron interaction.
