Enhanced gephyrin clustering during iLTP
(A) Representative epifluorescence image of a patched neuron expressing EGFP-gephyrin. Scale bar, 10 μm. The LFS protocol (40-s AP trains at 2 Hz) was delivered by patching the neuron. Please note that the fluorescence scale has been enhanced to visualize small clusters.
(B) Top: Pseudocolor magnification of the dendritic portion framed in (A). Scale bar, 2 μm. Bottom: Timelapse of the gephyrin cluster framed above. The arrow indicates LFS. Scale bar, 1 μm.
(C) EGFP-gephyrin fluorescence increases upon iLTP induction with LFS (arrow) (n = 13, F4,48 = 21.5, p < 0.001, RM one-way ANOVA followed by Tukey's post-test). Values are expressed as mean ± SEM. ∗∗∗p < 0.001.
