abstract = {Astrocytes play active roles in brain physiology by dynamic
interactions with neurons. Connexin 30, one of the two main
astroglial gap-junction subunits, is thought to be involved
in behavioral and basic cognitive processes. However, the
underlying cellular and molecular mechanisms are unknown. We
show here in mice that connexin 30 controls hippocampal
excitatory synaptic transmission through modulation of
astroglial glutamate transport, which directly alters
synaptic glutamate levels. Unexpectedly, we found that
connexin 30 regulated cell adhesion and migration and that
connexin 30 modulation of glutamate transport, occurring
independently of its channel function, was mediated by
morphological changes controlling insertion of astroglial
processes into synaptic clefts. By setting excitatory
synaptic strength, connexin 30 plays an important role in
long-term synaptic plasticity and in hippocampus-based
contextual memory. Taken together, these results establish
connexin 30 as a critical regulator of synaptic strength by
controlling the synaptic location of astroglial processes.},
