Naringin Attenuates Autophagic Stress and Neuroinflammation in Kainic Acid-Treated Hippocampus In Vivo
Kainic acid (KA) is well known as a chemical compound to study epileptic seizures and neuronal excitotoxicity. KA-induced excitotoxicity causes neuronal death by induction of autophagic stress and microglia-derived neuroinflammation, suggesting that the control of KA-induced effects may be important to inhibit epileptic seizures with neuroprotection. Naringin, a flavonoid in grapefruit and citr...
متن کاملEffects of focal injection of kainic acid into the mouse hippocampus in vitro and ex vivo.
Intra-hippocampal kainate injection induces an epileptiform activity termed status epilepticus. We examined the emergence of this activity with extracellular and intracellular records of responses (1) to focal kainate (KA) application in slices of mouse hippocampus and (2) of slices from mice injected with KA. The effects varied with distance from the injection site of KA. At distances less tha...
متن کاملInhibition of eNOS/sGC/PKG Pathway Decreases Akt Phosphorylation Induced by Kainic Acid in Mouse Hippocampus.
The serine/threonine kinase Akt has been shown to play a role of multiple cellular signaling pathways and act as a transducer of many functions initiated by growth factor receptors that activate phosphatidylinositol 3-kinase (PI3K). It has been reported that phosphorylated Akt activates eNOS resulting in the production of NO and that NO stimulates soluble guanylate cyclase (sGC), which results ...
متن کاملGlycyrrhizin Attenuates Kainic Acid-Induced Neuronal Cell Death in the Mouse Hippocampus
Glycyrrhizin (GL), a triterpene that is present in the roots and rhizomes of licorice (Glycyrrhiza glabra), has been reported to have anti-inflammatory and anti-viral effects. Recently, we demonstrated that GL produced the neuroprotective effects with the suppression of microglia activation and proinflammatory cytokine induction in the postischemic brain with middle cerebral artery occlusion (M...
متن کاملGhrelin attenuates kainic acid-induced neuronal cell death in the mouse hippocampus.
Ghrelin is an endogenous ligand for GH secretagogue receptor type 1a (GHSR1a), and is produced and released mainly from the stomach. It has been recently demonstrated that ghrelin can function as a neuroprotective factor by inhibiting apoptotic pathways. Kainic acid (KA), an excitatory amino acid l-glutamate analog, causes neuronal death in the hippocampus; previous studies suggest that activat...
