Representative immunoblots of lumbar spinal cord total lysates exhibit decreased pS880-GluA2 total levels following 20 µM Tat-P4-(C5)2, and Tat-C5 i.t. injections compared to saline injected animals. Densitometric analysis of immunoblot indicates a significant effect only for Tat-P4-(C5)2 (graph show mean +/- SEM and individual points, One-way ANOVA followed by Dunnett´s multiple comparisons test, ** p≤0.01, n=5-6/group as indicated by individual values)
