The role of nitric oxide in genetic model of absence epilepsy in rats

Abstract: Involvement of nitric oxide (NO) in the regulation of the epileptic activity was studied in WAG/Rij rats, a genetic model of absence epilepsy. I.c.v. administration of NO donors: S‐nitroso‐N‐acetylpenicillamine (SNAP, 0.5 and 5 μg), 3‐morpholino‐sydnonimine (SIN‐1, 0.5 and 5 μg) or sodium nitroprusside (SNP, 2 and 20 μg) enhanced namber of spike wave discharges (SWD) after the higher dose and had no effect on the mean duration of SWD. On the other hand, i.c.v. administration of NO synthase inhibitors, L‐NG‐Nit… Show more

“…To the contrary, injections of NMDA increase the number of SWDs (10). Additionally, agmatine inhibits all isoforms of NOS, and reduces production of the neuromodulator NO (19,20), and it is known that NO donors and biological precursor of NO increase the incidence of SWDs in WAG/Rij rats whereas inhibitors of neuronal NOS decrease the number of SWDs (37,38). While agmatine is known as a potent NMDAR antagonist and NOS inhibitor, the report on that 5-HT 1A receptor agonists counterbalance the decrease in number and duration of SWDs caused by NMDA antagonists (35), point to the importance or weight of other mechanisms in SWD generation.…”

“…Велика кількість інших лікарських засобів та лігандів було досліджено на моделі WAG/Rij абсансної епілепсії, таких як цитокіни [33,56,84], антидепресанти та антипсихотичні препарати [57], модулятори активності йонних каналів мембрани, інгібітори синтази оксиду азоту та його донори [54], нуклеозиди [32], агоністи каннабіноїдних рецепторів CB1 [11,91], аллостеричні модулятори метаботропних глутаматних рецепторів [10,44], а також нейропептиди [56,89]. Останнім часом проводяться дослідження ефектів нових блокаторів Т-типу кальцієвих каналів [55,75], патофізіологічних механізмів антиепілептогенеза [5,36,57,59,86], а також з метою експериментального припинення проявів абсансної епілепсії досліджуються різні типи нкеінвазивного та інвазивного подразнення електричним струмом та імпульсним магнітним полем [25,78,89].…”

“…Many other drugs and ligands were tested in the models for studying mechanism and processes affecting absence seizures, such as cytokines (van Luijtelaar et al, 2012a;Kovács et al, 2015;Russo et al, 2014), antidepressant and antipsychotic drugs (Russo et al, 2016), different ion channel openers and blockers, NO synthase inhibitors or NO donors (Przewlocka et al, 1996), nucleosides (Kovács et al, 2014), CB1 receptor agonists (van Rijn et al, 2010;Citraro et al, 2013), positive and negative allosteric modulators of mGluR (Celli et al, 2019;Ngomba and van Luijtelaar, 2018), and neuropeptides (for review see e.g. van Luijtelaar and Zobeiri, 2014;Russo et al, 2016).…”
