Isoform-specific expression of sodium channels in astrocytes in vitro: immunocytochemical observations.

abstract：:Previous in vitro studies using cell cultures or brain slices have demonstrated that phospholipase D (PLD) in the nervous system is involved in the signaling mechanism in response to a variety of agonists. However, little is known about the pathophysiological role of PLD-mediated signaling in the adult brain. We exami...
