It remains unclear how infantile febrile seizures (FS) enhance adult seizure susceptibility. Here we showed that the transient increase of interleukin-1β (IL-1β) after prolonged FS promoted adult seizure susceptibility, which was blocked by interleukin-1 receptor antagonist (IL-1Ra) within a critical time window. Postnatal administered IL-1β alone mimicked(More)
Low-frequency stimulation (LFS) is emerging as a new option for the treatment of epilepsy. The present study was designed to determine whether there is a crucial period for the treatment of epileptogenesis with LFS. LFS was delivered at different time-points to evaluate its anti-epileptogenic effect on amygdala-kindling rats. 18F-fluorodeoxyglucose(More)
High-frequency stimulation (HFS) of the anterior nucleus of thalamus (ANT) is a new and alternative option for the treatment of intractable epilepsy. However, the responder rate is relatively low. The present study was designed to determine the effect of low-frequency stimulation (LFS) in ANT on chronic spontaneous recurrent seizures and related(More)
A safe and effective therapy for epilepsy requires a drug delivery system that can penetrate the blood-brain barrier and subsequently release antiepileptic drugs rapidly to suppress neuronal discharges in a timely manner. We have developed electro-responsive hydrogel nanoparticles (ERHNPs) modified with angiopep-2 (ANG) to facilitate the delivery of the(More)
BACKGROUND Low-frequency stimulation (LFS, <5 Hz) has been proposed as an alternative option for the treatment of epilepsy. The stimulation pole, anode and cathode, may make different contributions to the anti-epileptic effect of LFS. OBJECTIVE To determine whether electrode polarity influences the anti-epileptic effect of LFS at the kindling focus in(More)
Brain inflammation is a major factor in epilepsy, and the high mobility group box-1 (HMGB1) protein is known to contribute significantly to the generation of seizures. Here, we investigated the therapeutic potential of an anti-HMGB1 monoclonal antibody (mAb) in epilepsy. anti-HMGB1 mAb attenuated both acute seizure models (maximal electroshock seizure,(More)
Positive transfer of secondary focus (PTS) refers to new epileptogenesis outside the primary focus and is minimally controlled by existing treatments. Low-frequency stimulation (LFS) has benefits on the onset of epilepsy and epileptogenesis. However, it's unclear whether LFS can retard the PTS in epilepsy. Here we found that PTS at both contralateral(More)
Low-frequency stimulation (LFS) is emerging as a new option for the treatment of intractable epilepsy. The stimulation duration may influence the anti-epileptic effect of LFS but is poorly studied. The present study was designed to evaluate the anti-epileptic effect of focal LFS with different stimulation duration on amygdaloid-kindling seizures in rats. We(More)
Secondary generalized seizure (sGS) is a major source of disability in temporal lobe epilepsy (TLE) with unclear cellular/circuit mechanisms. Here we found that clinical TLE patients with sGS showed reduced volume specifically in the subiculum compared with those without sGS. Further, using optogenetics and extracellular electrophysiological recording in(More)
Environmental exposure early in development plays a role in susceptibility to disease in later life. Here, we demonstrate that prolonged febrile seizures induced by exposure of rat pups to a hyperthermic environment enhance seizure susceptibility not only in these hyperthermia-treated rats but also in their future offspring, even if the offspring never(More)
