Dual mechanisms of rapid expression of anxiety-related behavior in pilocarpine-treated epileptic mice.

A mouse model of epilepsy was generated by inducing status epilepticus (SE) for either 1.5 or 4.5h with pilocarpine to study anxiety-related behaviors, changes in the electroencephalogram of the cerebral cortex and hippocampus, and expression of hippocampal proteins.

NMDA receptor-dependent recruitment of calnexin to the neuronal plasma membrane.

Calnexin is a molecular chaperone that resides in the endoplasmic reticulum and participates in the folding and assembly of nascent proteins. In the present study, calnexin was found in both synaptic and non-synaptic membrane components of rat brain tissue. Immunohistochemical staining of mouse hippocampal sections revealed the presence of calnexin in the neuronal cell soma, as well as dendrite-enriched regions.
