The aquaporin-4 (AQP4) pool in the perivascular astrocyte membranes has been shown to be critically involved in the formation and dissolution of brain edema. Cerebral edema is a major cause of morbidity and mortality in stroke. It is therefore essential to know whether the perivascular pool of AQP4 is up- or down-regulated after an ischemic insult, because(More)
AMPA receptors have been identified in different populations of presynaptic terminals and found to be involved in the modulation of neurotransmitter release. The mechanisms that govern the expression of presynaptic AMPA receptors are not known. One possibility is that pre- and postsynaptic AMPA receptors are regulated according to the same principles.

Functional evidence suggests that neuronal enriched endosomal protein of 21 kDa (NEEP21) takes part in facilitating transport of AMPA receptors (AMPAR) in the synapse. To explore the anatomical basis for a role in this synaptic trafficking, we investigated the ultrastructural localization of NEEP21 in rodent brain. Using immunogold electron microscopy, we(More)
