Kaneko教授の研究室は、神経細胞の酸化的損傷とカルシウムイオンチャネルの関連を解明する神経生物学を専門としています。特にTRPM2やTRPV4といったチャネルが神経炎症や神経変性疾患における神経障害に果たす役割を、細胞・分子レベルで解明しています。また、てんかん治療における薬物療法の安全性や、神経伝達の分子機構に関連するチャネルの新規スプライシングバリアントの同定にも取り組んでいます。

A brief exposure to hydrogen peroxide (H2O2) induces severe deterioration of primary cultured neurons in vitro. We have investigated a link between the H2O2-induced neuronal death and Ca2+-permeable TRPM2 channels regulated by ADP-ribose (ADPR). In cultured cerebral cortical neurons from fetal rat, TRPM2 proteins were detected at cell bodies and neurite extensions. Application of H2O2 to the cultured neurons elicited an increase in intracellular Ca2+ concentration ([Ca2+]i) caused by Ca2+ influx

Microglia are intrinsic immune cells in the brain. In response to neurodegenerative events, excessively activated microglia change their shapes and release various cytokines leading to the pathogenesis of central nervous system (CNS) disease. Because the intracellular mechanisms of this process are still unclear, we have evaluated the functional roles of transient receptor potential vanilloid 4 (TRPV4) channel expressed in the microglia. Robust microglial activation after an injection of lipopol
Adjunctive perampanel (8 and 12 mg/d) significantly improved seizure control in patients with refractory POS. Safety and tolerability were acceptable at daily doses of perampanel 4-12 mg.
To assess the relative contribution of antiepileptic drugs (AEDS) to occurrence of congenital malformations, we compared two prospective studies. We analyzed data for 14 AEDs for total daily doses (drug score) and eight background factors. From the first study, the drug score and polytherapy--particularly the use of valproate plus carbamazepine--were suspected to be primary factors for increased incidence of congenital malformation. In the other study, the drug score for each case was decreased,
The physical interaction between the presynaptic vesicle release complex and the large cytoplasmic region linking domains II and III of N-type (Ca(v)2.2) calcium channel alpha(1)B subunits is considered to be of fundamental importance for efficient neurotransmission. By PCR analysis of human brain cDNA libraries and IMR32 cell mRNA, we have isolated novel N-type channel variants, termed Ca(v)2.2-Delta1 and Delta2, which lack large parts of the domain II-III linker region, including the synaptic
