[Domoic acid and glutamate receptors]

Domoic acid is a kind of neurotoxin produced by diatoms and accumulated in food chain, which is harmful to the human health. The N-methyl-D-aspartate receptor and kainic acid/alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate receptor could be activated by domoic acid. The concentration of the intracellular Ca2+ could be elevated, causing a series of physiological and biochemical changes. The possible mechanisms of neurotoxicity induced by domoic acid through glutamate receptors are discussed.
