Outline of Final Research Achievements |
Towards the goal of characterizing the dynamic interaction between astrocytes and synapses and identifying the underlying molecular mechanisms, we first constructed astrocyte-specific probes and validated promoters for astrocyte-specific expression. We then estabished virus production and stereotactic injection system to enable astrocyte-specific molecular manipulation in acute hippocampal slice preparations. Furthermore, we explored the role for gap junctions, which had previously been implicated in affecting asrtocyte-synapse structural contacts, and identified a functional role for the connexins, the gap junction proteins, in controlling synaptic strength and plasticity.
