Figure 7A. Representative confocal images from EGFP-GSK3α FRAP experiments in organotypic slices cultured from C57 wild-type mice. Upper left panel ('Baseline') shows EGFP-GSK3α expression in a dendrite and dendritic spine. The spine was bleached ('Bleach'; yellow dashed circle) and its fluorescence partially recovered 90 s later ('Recovery'). Single dendritic spines were imaged once per second for 10 seconds prior to, and for 90 seconds following, spine photobleaching. Such single FRAP experiments were performed on different spines during basal conditions ('basal'; upper panels), immediately after cLTD induction with 20 µM NMDA for 5 minutes ('cLTD'; middle panels), and immediately following 10 minutes of washout ('washout'; lower panels). Scale bars = 1 µm. B. Time course of fluorescence recovery during FRAP experiments described in A. White circles ('basal') show the average spine/dendrite fluorescence of FRAP on EGFP-GSK3α-expressing spines in wild-type mouse slices prior to cLTD induction. Pink circles ('cLTD') show fluorescence in spines in which cLTD had been induced using 20 µM NMDA. Green circles ('washout ') represent the average of spine fluorescence after NMDA washout for 10 minutes. Recovery trajectories for the three conditions are fitted with two-phase exponential curves (red lines). C, D. As A, B but in slices cultured from C57 tauKO mice. Scale bars = 1 µm. E. Quantification of last 10 seconds of fluorescence recovery (90-100 seconds) in B and D. Error bars represent SEM and statistical significance was calculated according to the Mann-Whitney U test. N = 13, 11 and 12 spines for wt baseline, cLTD and recovery and 9, 7 and 5 spines for tauKO baseline, cLTD and recovery groups, respectively.F. Spine/dendrite ratios showing enrichment of EGFP-GSK3α in wild-type or tauKO slices in 'baseline', 'cLTD' or 'recovery' conditions.
