We examined the effects of dexamethasone on the expression of the inducible transcription factor c-fos in 4-aminopyridine (4-AP) seizures.

The expression level of the c-fos gene was estimated by counting the striatal c-fos-immunostained cell nuclei at the time intervals of the microdialysis. 4-aminopyridine elicited high-frequency seizure discharges in the EEG and significantly increased glutamate, aspartate, GABA, serotonin, noradrenaline, and dopamine levels in the extracellular dialysates.

METHODS: Depth electrode recordings and postmortem assessment of regional c-fos mRNA levels were used to characterize the distribution of aberrant discharge activity during spontaneous seizures in vivo.
Electrophysiologic recordings of spontaneous and evoked activity also were performed by using in vitro brain slices from the tish rat treated with proconvulsant drugs (penicillin and 4-aminopyridine).

J Neurochem. 2005 Oct;95(1):111-24.

Here we analysed the effects of one-sided lateral EC (LEC) and temporoammonic (alvear) path lesion on the development and properties of 4-aminopyridine-induced seizures.

We examined the effects of non-competitive NMDA glutamate receptor antagonists on seizures elicited by 4-aminopyridine (4-AP), and in particular, on the expression of the transcription factor c-fos induced by these seizures.

The systemic administration of the K+ channel blocker 4-aminopyridine (4-AP, 5 mg/kg, i.p.) induced expression of c-Fos in the hippocampal neuronal cell layer, which expression was completely abolished by the noncompetitive NMDA receptor antagonist MK-801, thus indicating that the administration of 4-AP would activate NMDA receptors in the hippocampal neurons.

The effect of acute brief seizures on neocortical c-fos expression was investigated in rats injected with 5 mg/kg 4-aminopyridine.

However, the effects on neuronal c-fos expression and astrocyte swelling were complex.
