1 Amantadine (N-methyl-D-aspartate (NMDA) receptor noncompetitive antagonist), NVP-AAM077 (GluN2A-containing NMDA receptor selective inhibitor) and Ro25-6981 (GluN2B-containing NMDA receptor selective inhibitor) also suppressed the Abeta25-35-induced PSD-95 tyrosine phosphorylation.Conclusion: These results suggest that Abeta oligomers induce the tyrosine phosphorylation of PSD-95 by SrcPTKs, which is mediated by the activation of GluN2A- and GluN2B-containing NMDA receptors.Section: Disease-Related Neuroscience. Tyrosine amyloid beta precursor protein Rattus norvegicus
