Kainic acid-induced neurodegenerative model: potentials and limitations Zheng XY; Zhang HL; Luo Q; Zhu JJ Biomed Biotechnol 2011[]; 2011 (ä): 457079Excitotoxicity is considered to be an important mechanism involved in various neurodegenerative diseases in the central nervous system (CNS) such as Alzheimer's disease (AD). However, the mechanism by which excitotoxicity is implicated in neurodegenerative disorders remains unclear. Kainic acid (KA) is an epileptogenic and neuroexcitotoxic agent by acting on specific kainate receptors (KARs) in the CNS. KA has been extensively used as a specific agonist for ionotrophic glutamate receptors (iGluRs), for example, KARs, to mimic glutamate excitotoxicity in neurodegenerative models as well as to distinguish other iGluRs such as alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate receptors and N-methyl-D-aspartate receptors. Given the current knowledge of excitotoxicity in neurodegeneration, interventions targeted at modulating excitotoxicity are promising in terms of dealing with neurodegenerative disorders. This paper summarizes the up-to-date knowledge of neurodegenerative studies based on KA-induced animal model, with emphasis on its potentials and limitations.|*Disease Models, Animal[MESH]|*Kainic Acid[MESH]|Animals[MESH]|Neurodegenerative Diseases/*chemically induced/metabolism[MESH]|Receptors, Kainic Acid/metabolism[MESH]|Signal Transduction[MESH] |
