毒性Focal injection of quinolinic acid into specific areas of the brain produces neuronal damage although sparing axons of passage. Similarities between the biochemical and morphological profiles of these lesions and human neuropathy seen in neurodegenerative diseases have led to the proposal that endogenous excitotoxins may play a role in such neurodegenerative disease states. Quinolinic acid is an intermediate in the kynurenine pathway of tryptophan metabolism and has been detected in the brains of several mammals including man. The neuroexcitatory action is thought to be mediated via interaction with the N-methyl-D-aspartate (NMDA) receptor of the glutamate family. No mechanism for quinolinic acid removal, nor for synaptic inactivation, has been found, and consequently accumulation of concentrations capa_x0002_ble of inducing neuronal degeneration and death may occur.
