Relative mRNA expression of NMDA receptor subunits and PV in PV-ir interneurons in normal adult rat PFC versus treatment with MK-801. A, it is clear that the mRNA expression of NR2A subunit is significantly higher than that of NR2B (p<0.05) in the PV-ir interneurons of adult rat PFC (postnatal day 90). Note the high expression of PV and undetectable level of NR2D subunit in PV-ir cells. B, subchronic treatment with MK-801 significantly downregulated the mRNA expression of PV to an almost undetectable level (337.2-fold) and all subunits of NMDA receptors in PV-ir interneurons, i.e., 6.13-fold for NR1, 17.7-fold for NR2A, and 21.0-fold for NR2B (p<0.05).
