Effects of ischaemic conditions on uptake of glutamate, aspartate, and noradrenaline by cell lines derived from the human nervous system.

abstract：:Ras-related GTPases of the Rho family, such as RhoA and RhoB, are well-characterised mediators of morphological change in peripheral tissues via their effects on the actin cytoskeleton. We tested the hypothesis that Rho family GTPases are involved in synaptic transmission in the CA1 region of the hippocampus. We show ...
