G. Western blots against NPC1 and actin-β (ACTB) in synaptosomes from wt and NPC1nmf164 mice in which cLTP was induced or not in the presence or absence of the protein synthesis inhibitor cycloheximide (CHX). Graphs show mean ± SEM NPC1 level normalized to ACTB as a percentage of control (wt non cLTP induced) values (n=3 mice, 3 month-old, 2-way ANOVA, ***p < 0.001).
