<p><i>A.</i> Inhibition of the formation of dendritic swellings caused by treatment with 0.2 µg/ml PLY for 5 h by the application of 10 µM of the non-competitive NMDA-receptor inhibitor MK801. *** p<0.001 vs. all. <i>B.</i> Preserved dendritic spine number following treatment with 10 µM MK801 together with 0.2 µg/ml PLY for 5 h. * p<0.05, ** p<0.01. <i>C.</i> Reversal of the PSD95 density loss by PLY when incubated with 10 µM MK801. <i>D.</i> Complete inhibition of dendritic swelling formation caused by treatment with 0.2 µg/ml PLY for 5 h using a 50 µM of the competitive NMDA-receptor antagonist D-AP5. *** p<0.001. All values represent the mean ± SEM; n = 5–6 slices from at least 3 independent experiments.</p
