Effects of long-term treatment with the neuroleptics haloperidol, clozapine and olanzapine on immunoexpression of NMDA receptor subunits NR1, NR2A and NR2B in the rat hippocampus.

Abstract

Antagonists of the N-methyl-d-aspartate receptor (NMDA-R) are associated with symptoms of schizophrenia, leading to the hypothesis that NMDA-R hypofunction leads to the pathogenesis of disease. We evaluated the long-term effect of neuroleptic administration on the NMDA subunits via immunohistochemical analysis.
