| Outline of Final Research Achievements |
We investigate our hypothesis that inhibition of SV2A can stabilize the neurogenesis and consequently prevent the epileptogenesis. We evaluated an appearance and electrical characteristics of newborn cells in the hippocampus after initial seizure insult in this study. We counted and observed its morphology of newborn cells among Levetiracetam (LEV) (SV2A stabilizer) treatment and non-treatment groups. The number of newborn neurons in the LEV group was significantly less than that of the non-treatment group. Furthermore, LEV made normalized the cell appearance. In the results of patch-clump method, early appeared newborn neurons were immature with easily excitable characteristics, however survived neuron for 28 days from initial seizure insult showed the same electrical characteristics as that of matured neuron. From these results, stabilization of SV2A after an initial incentive has a possibility to prevent inducing epileptogenicity through neurogenesis.
