The link between cerebral small vessel disease (CSVD) and epilepsy has been poorly investigated. Some reports suggest that CSVD may predispose to temporal lobe epilepsy (TLE). Aim of this study was to evaluate whether spontaneously hypertensive rats (SHRs), an established model of systemic hypertension and CSVD, have a propensity to develop TLE more than generalized seizures. To this aim, amygdala kindling, as a model of TLE, and pentylenetetrazole (PTZ)-induced kindling, as a model of generalized seizures, have been used to ascertain whether SHRs are more prone to TLE as compared to Wistar Kyoto control rats...

Nitric oxide (NO), an important intracellular signaling molecule is involved in modulation of neuronal transmission. The NO level increases during epileptic activity in animal models of epilepsy. However, its role in epileptic activity remains controversial. Spermine is an endogenous polyamine; possesses anti-oxidant property and has ability to modulate ion channels and NO synthase activity. Therefore, the present study was designed to investigate the role of NO pathway in the neuroprotective effect of spermine, in Pentylenetetrazol (PTZ) induced kindling epilepsy in mice...

Oxidative stress is implicated in epileptogenesis as well as in the metabolic changes associated with increased risk of atherosclerotic vascular disease in epilepsy. The present work investigated the impact of the antioxidants trimetazidine (TMZ) on the antiepileptic activity of valproic acid (VAP) and on the metabolic and histological changes in hippocampal, aortic and hepatic tissues associated with epilepsy and/or VPA. Rats were divided into: Non-Pentylentetrazole (PTZ) group; subdivided into: control and VPA treated groups, PTZ-treated group subdivided into: PTZ, PTZ/VPA, PTZ/TMZ, PTZ/VPA+TMZ groups...

Somatostatin is expressed widely in the hippocampus and notably in hilar GABAergic neurons that are vulnerable to seizure neuropathology in chronic temporal lobe epilepsy. We previously demonstrated that sustained bilateral preprosomatostatin (preproSST) expression in the hippocampus prevents the development of generalized seizures in the amygdala kindling model of temporal lobe epilepsy. Here we tested whether sustained preproSST expression is anticonvulsant in rats already kindled to high-grade seizures. Rats were kindled until they exhibited 3 consecutive Racine Grade 5 seizures before adeno-associated virus serotype 5 (AAV5) vector driving either eGFP (AAV5-CBa-eGFP) or preproSST and eGFP (AAV5-CBa-preproSST-eGFP) expression was injected bilaterally into the hippocampal dentate gyrus and CA1 region...

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 pentylenetetrazole-induced and kindling-induced), and chronic epilepsy model (kainic acid-induced) in a dose-dependent manner. Meanwhile, the anti-HMGB1 mAb also attenuated seizure activities of human brain slices obtained from surgical resection from drug-resistant epilepsy patients...

BACKGROUND: In humans, convulsive diseases such as temporal lobe epilepsy are usually accompanied by learning and memory impairments. In recent years, the role of gap junction channels as an important target of antiepileptic drugs has been studied and discussed. Quinine, as a gap junction blocker of connexin 36, can abolish ictal epileptiform activity in brain slices. OBJECTIVES: The role of quinine in memory retrieval in pentylenetetrazole (PTZ)-kindled rats was examined using a step-through passive avoidance task...

The AMP-activated protein kinase (AMPK) is a key energy sensor. Its activator metformin could suppress epileptogenesis in the pentylenetetrazol (PTZ) kindling model. However, the effect of metformin on the acute and chronic seizures has not been studied. We first detected the expression of AMPK in the brain tissue of human and mice with chronic seizures, as well as in mice with acute seizures. Second, using behavioral assay and local filed potentials (LFPs) recording, we investigated the effect of chronic metformin treatment on seizures in a acute seizure model and a chronic seizure model...

Cognitive dysfunction is commonly observed in epileptic patients. Pentylenetetrazole (PTZ) kindling is a well established animal model which simulates clinical epilepsy. This study evaluated the potential role of glutamate, oxidative stress and nitric oxide (NO) overproduction in pentylenetetrazole (PTZ)-induced kindling and associated cognitive impairments in mice and effect of thymoquinone on these parameters. Repeated treatment of mice with a subconvulsive dose of PTZ (35mg/kg i.p.) once every alternate-day for 12 injections induced kindling...

Epilepsy is one of the most common neurological disorders in humans, and the role of the cerebellum in its physiopathology remains the subject of study. The Purkinje cells (PC), whose axons target the dentate and interpositus nuclei, form the main cerebellar output to forebrain structures involved in epilepsy. Cerebellar atrophy related to loss of PC has been reported in chronic epilepsy although its mechanism remains unclear. Taking in account that an overexpression of β-Catenin has been related with cell death, here we present the signaling of β-Catenin and the type of PC death in cerebellum of rats with chronic seizures induced by the amygdaloid kindling model...

As a promising method for treating intractable epilepsy, the inhibitory effect of low-frequency stimulation (LFS) is well known, although its mechanisms remain unclear. Excessive levels of cerebral glutamate are considered a crucial factor for epilepsy. Therefore, we designed experiments to investigate the crucial parts of the glutamate cycle. We evaluated glutamine synthetase (GS, metabolizes glutamate), glutaminase (synthesizes glutamate), and glutamic acid decarboxylase (GAD, a γ-aminobutyric acid [GABA] synthetase) in different regions of the brain, including the dentate gyrus (DG), CA3, and CA1 subregions of the hippocampus, and the cortex, using western blots, immunohistochemistry, and enzyme activity assays...

OBJECTIVE: Potential clinical utility of galanin or peptidic analogs has been hindered by poor metabolic stability, lack of brain penetration, and hyperglycemia due to galanin receptor subtype 1 (GalR1) activation. NAX 810-2, a galanin receptor subtype 2 (GalR2)-preferring galanin analog, possesses 15-fold greater affinity for GalR2 over GalR1 and protects against seizures in the mouse 6 Hz, corneal kindling, and Frings audiogenic seizure models. The purpose of these studies was to further evaluate the preclinical efficacy and pharmacokinetics of NAX 810-2 in mice...

Epilepsy is one of the major neurological disorders frequently associated with psychiatric disorders such as depression. The predisposition of tryptophan metabolism towards kynurenine pathway has been reported as one of the plausible reasons for association of depression in epilepsy. Hence, this study was envisaged to evaluate the dose dependent inhibition of indoleamine 2,3-dioxygenase (IDO) enzyme employing quercetin (screened employing in vitro method) with levetiracetam for combined management of epilepsy and comorbid depression...
