General description

Kainic acid is an agonist for kainate-class ionotropic glutamate receptors. Kainate receptors directly gate ion channels and are generally excitatory. Excess stimulation by Kainic acid induces neurocytosis (apoptosis) and epileptic seizures.

Application

Kainic acid is used to study mechanisms of excitation-induced apoptosis and epilepsy.

Biochem/physiol Actions

Kainic acid monohydrate is an agonist at the kainate class of ionotropic glutamate receptors, which induces seizures and neurodegeneration in vivo and is used to induce experimental epilepsy in rodents and study the mechanisms of excitation-induced neuronal apoptosis.
