Figure 6. The Role of NR2B Subunit in Enhanced CA1-LTP in Transgenic Hippomcampal Slices.

Figure 6

A: Effects of NR2A-selective antagonist, NVP-AAM077, on wild-type slices. B: NVP-AAM077 also significantly reduced, but not completely blocked, CA1 LTP in transgenic slices. C: Statistical analysis shows the effects of NVP-AAM077 on LTP in both Tg and Wt slice. It indicates a significant involvement of NR2A-containing NMDARs in CA1-LTP induction in both Tg and WT slices. D: There was a significant, but small, effect of NR2B-selective antagonist, Ro25-6981, on CA1-LTP in wild-type slices. E: Ro25-6981 had much larger effect on CA1-LTP in transgenic slices, but it did not completely block LTP in transgenic slices. F: Summarized effects of Ro25-6981 on CA1-LTP in both Tg and Wt slice. G: Combination of NVP-AAM077 and Ro25-6981 completely blocked the formation of CA3-CA1 LTP completely in the wild-type slices. H: Complete blockage of CA1-LTP in transgenic slices by combined application of NVP-AAM077 and Ro25-6981. I: Statistical analysis shows the combined effects of NVP-AAM077 and Ro25-6981 on CA1-LTP.
