Excessive glutamate signaling can lead to excitotoxicity, a phenomenon whereby over-activation of glutamate receptors initiates neuronal death. In recent years, it has been shown that glutamate can be toxic to white-matter oligodendrocytes. Up to recently, the prevailing view was that oligodendrocyte excitotoxicity is mediated by alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) a...

Abstract Neurodegenerative disorders are associated with causes such as induction of oxidative stress, alterations in Ca 2+ homeostasis, abnormal protein aggregation, inflammatory processes, excitotoxicity, and apoptosis. In addition to the above, food transition recent years has led changes dietary patterns, increasing consumption ultra-processed processed foods that can lead lipotoxicity indu...

A body of evidence suggests that the mechanisms of excitotoxic neuronal damage evoked by excessive or prolonged activation of the excitatory amino acid receptors may be involved in pathogenesis of brain damage in acute insults and in chronic neurodegenerative diseases. In this review we briefly discuss several selected mechanisms of the excitotoxicity, focusing attention on the role of ionotrop...

Diabetes can exacerbate seizures and worsen seizure-related brain damage. In the present study, we aimed to determine whether the standard antiepileptic drug pregabalin (PGB) protects against pilocarpine-induced seizures and excitotoxicity in diabetes. Adult male Sprague-Dawley rats were divided into either a streptozotocin (STZ)-induced diabetes group or a normal saline (NS) group. Both groups...
