NR2B-containing NMDA receptors are up-regulated in temporal cortex in schizophrenia. Neuroreport, 1999, Feb-25, Volume: 10, Issue:3 Saturation analyses of [3H]L-689,560, [3H]CGP 39653 and NMDA-specific [3H]ifenprodil binding revealed an equivalent increase (0.7 pmol/mg) in the number of [3H]L-689,560 and [3H]ifenprodil binding sites in superior temporal cortex (BA22) from drug-treated chronic schizophrenic patients and control subjects. No differences were observed between control and schizophrenic subjects for [3H]CGP 39653 binding in BA22, or for any of the radioligands binding to pre-motor cortex (BA6). Since [3H]L-689,560, [3H]CGP 39653 and [3H]ifenprodil label the glycine, glutamate and ifenprodil sites of the NMDA receptor complex, which are associated with NR1, NR1/NR2A and NR1/NR2B subunits respectively, our findings suggest that NR2B-containing receptors are selectively up-regulated in superior temporal cortex in schizophrenia.

NMDA receptors with different sensitivities to magnesium and ifenprodil control the release of [14C]acetylcholine and [3H]spermidine from rat striatal slices in vitro. Journal of neurochemistry, 1994, Volume: 62, Issue:5 KCl (20-100 mM) and N-methyl-D-aspartate (NMDA, 100-1,000 microM) produce concomitant concentration-dependent increases in the release of previously captured [14C]acetylcholine and [3H]spermidine from rat striatal slices in vitro. The effects of NMDA (300 microM) on striatal [14C]acetylcholine and [3H]spermidine release were blocked with equal potencies by the competitive NMDA antagonist CGP 37849, the glycine site antagonist L-689,560, and the NMDA channel blocker dizocilpine. In contrast, although NMDA-evoked [14C]acetylcholine release was antagonized by ifenprodil (IC50 = 5.3 microM) and MgCl2 (IC50 = 200 microM), neither compound antagonized the NMDA-evoked release of [3H]spermidine at concentrations up to 100 microM (ifenprodil) or 1 mM (MgCl2). Distinct NMDA receptor subtypes with different sensitivities to magnesium and ifenprodil therefore exist in the rat striatum.

NMDA receptors with different sensitivities to magnesium and ifenprodil control the release of [14C]acetylcholine and [3H]spermidine from rat striatal slices in vitro.
