Figure 6From: Astrocytic Ca2+ signals are required for the functional integrity of tripartite synapsesInvolvement of astrocytic Ca2+in tripartite synapses. (A) Control astrocytes. (B) IP3 sponge-expressing astrocytes. Suppression of Ca2+ activity in IP3 sponge-expressing astrocytes leads to retraction of astrocytic processes from the synapse, which moves astrocytic glutamate transporters further away and allows for more glutamate spillover.Back to article page
