Serum deprivation and NGF induce and modulate voltage-gated Na(+) currents in human astrocytoma cell lines.

abstract：:Accumulating evidence supports the idea that synapses are tripartite, whereby perisynaptic astrocytes modulate both pre- and postsynaptic function. Although some of these features have been uncovered by using electrophysiological methods, less is known about the structural interplay between synapses and glial processe...
