| Research Abstract |
Epileptic seizures cause continuous pathological and electrophysiological hippocampul (HIPP) changes, inducing epileptogenesis (EG). Control of this process has not been found until now. Aiming pharmacological control on induced EG, we evaluated treatment effect of levetiracetam (LEV) on pathological changes in epileptic mice HIPPi where continuous LEV treatment suppressed epilepsy-induced neurogenesis. Preventive LEV treatment potentially inhibits such pathological changes. Cellular and molecular mechanisms of EG induction, however, remain unclear. Brain inflammatory mechanisms activation received recently broad attention as a factor in acquired EG. Our preliminary clinical study suggested elevated expression of HMGB1 and TLR4 in sclerotic HIPPi, indicating HMGB1-TLR4 pathway involvement in human EG. More, in human EG HIPP, HMGB1 involved consequently TLR4, probably in relation to HIPP sclerosis induction (CA1> DG> CA2) and atrophy,
