Tuberous sclerosis complex (TSC) and focal cortical dysplasia type IIb (FCDIIb) are characterized by epilepsy-associated cerebral cortical malformations. To understand the potential role of the inflammatory cytokine interleukin 6 (IL-6) in the pathogenesis of these lesions, we analyzed the IL-6 system in TSC and FCDIIb cortical lesions and in control cortex(More)
Transient receptor potential vanilloid type-1 (TRPV1) is a ligand-gated nonselective cation channel that has been well characterized in peripheral pain pathway. Recent evidence from animal models of temporal lobe epilepsy (TLE) has supported the important role of TRPV1 in epileptogenesis. In this study, we investigated the expression and cellular(More)
Cortical tubers are malformations of cortical development in patients with tuberous sclerosis complex (TSC), and highly associated with pediatric intractable epilepsy. Recent evidence has shown that signaling mediated through vascular endothelial growth factor-C (VEGF-C) and its receptors, VEGFR-2 and VEGFR-3, has direct effects on both neurons and glial(More)
We have investigated the direct excitatory effects of hypocretin-1 on acutely isolated prefrontal cortical pyramidal neurons and explored the signaling mechanisms of these actions. Puff application of hypocretin-1 caused an excitation in the recorded neurons. These effects of hypocretin-1 were abolished by a phospholipase C inhibitor D609, demonstrating(More)
The reticulon protein Nogo-A is an important regulator of neurite growth, axonal plasticity, and cell migration in the central nervous system. Previous studies have shown markedly elevated levels of Nogo-A in human temporal lobe epilepsy. In the present study, we examined the expression pattern of the Nogo-A system in cortical lesions of pediatric patients(More)
Tuberous sclerosis complex (TSC) and focal cortical dysplasia type IIb (FCDIIb) are recognized as causes of intractable epilepsy. Transient receptor potential vanilloid receptor 1 (TRPV1), a member of the transient receptor potential family, is the capsaicin receptor and is known to be involved in peripheral nociception. Recent evidence suggested that TRPV1(More)
Neuronal nuclei (NeuN) is a well-recognized “marker” that is detected exclusively in post-mitotic neurons and was initially identified through an immunological screen to produce neuron-specific antibodies. Immunostaining evidence indicates that NeuN is distributed in the nuclei of mature neurons in nearly all parts of the vertebrate nervous system. NeuN is(More)
Focal cortical dysplasia (FCD) is a well-known cause of medically intractable epilepsy. To understand the potential role of the inflammatory cytokine interleukin 2 (IL-2) in the pathogenesis of FCD, we investigated the expression patterns of IL-2 and its receptors (IL-2Rs) in FCD and control samples that included epileptic neocortex from mesial temporal(More)
The role of interleukin 17 (IL-17) to epilepsy-associated cortical tubers of tuberous sclerosis complex (TSC) is unknown. We investigated the expression patterns of the IL-17 and IL-17 receptor (IL-17R) in cortical tubers of TSC compared with normal control cortex (CTX). We found that IL-17 and IL-17R were clearly upregulated in cortical tubers at the(More)
Sudden unexpected death in epilepsy (SUDEP) is the leading cause for death in individuals with epilepsy. The frequency of SUDEP correlates with the severity of epilepsies and lack of response to antiepileptic drug treatment, but the underlying mechanisms of SUDEP have not been elucidated fully. GABRG2(Q390X) is a mutation associated with the epileptic(More)
