pubmed:abstractText |
Exposure of chick telencephalon neurons in serum-free primary culture to glutamate produced a concentration-dependent cell toxicity as seen by an increase in lactate dehydrogenase (LDH) release that was blocked by the N-methyl-D-aspartate (NMDA) receptor antagonist dizocilpine and was reduced by preincubation with the cholinergic agonist carbachol. Preincubation with a threshold concentration of NMDA did not prevent glutamate toxicity, suggesting that chick NMDA receptors do not desensitize in the manner reported for their rodent counterparts. Neither anandamide (arachidonyl ethanolamide, AEA) nor palmitoylethanolamide (PEA) was able to prevent the neurotoxicity produced by prolonged glutamate incubation, even under conditions in which the metabolism of the compounds by fatty acid amide hydrolase or AEA cellular uptake was blocked. It is concluded that treatments reported as granting neuroprotection towards glutamate toxicity in rodent primary neuronal cultures do not necessarily show the same properties in the chick.
