PURPOSE: The selective contribution of neuronal gap junction (GJ) communication via connexin 36 (Cx36) channels to epileptogenesis and to the maintenance and propagation of seizures was investigated in both the primary focus and the mirror focus by using pharmacologic approaches with the 4-aminopyridine in vivo epilepsy model.

Moreover, epileptiform discharges elicited by 4-aminopyridine were attenuated in slices from Cx36 -/- mice.

However, bath application of the potassium channel blocker 4-aminopyridine (4-AP; 20-80 microM) produced a pattern of activity in control mice (13/16 slices), consisting of burst discharges occurring in conjunction with kainate-evoked gamma-frequency oscillations, that was similar to that seen in Cx36KO mice.

This finding suggested that pannexin1 and connexin36 are involved in different functional roles or that they are expressed in different cell types and that only those expressing the Cx36 are induced to apoptosis by epileptic seizures.

PURPOSE: The possible role of gap junctions in the manifestation and control of the duration of seizures was tested on the 4-aminopyridine-induced epilepsy model in rats in vivo, by using electrophysiologic, pharmacologic, and molecular biologic techniques.
RESULTS: After repeated seizures, the expression levels of Cx32, Cx43, and Cx36 mRNAs at the epileptic foci were increased significantly.
