Loss of caldendrin leads to an increased frequency of SER entry and decreased fraction of stable SER in dendritic protrusions of mouse primary hippocampal neurons.Figure 6A 10 min time-lapse imaging of DIV12 wild-type (cald WT), caldendrin knock-out (cald KO), caldendrin knock-out expressing caldendrin-GFP (cald KO + cald-GFP) or caldendrin knock-out treated with jasplakinolide (cald KO + JPK) mouse primary hippocampal neurons, additionally expressing a cell fill (maxGFP) and an ER-marker (ER-tDimer). Yellow arrows indicate protrusions with a stably anchored ER (>10 min). Blue arrows indicate protrusions that show transient presence of ER. Scale bar = 5 µm. B Quantification of dynamic SER presence in protrusions of cald WT, cald KO, cald KO + cald-GFP and cald KO + JPK neurons across individual cells, suggesting higher dynamics for cald KO and cald KO + JPK neurons as seen from an increase of protrusions with transiently present ER compared to cald WT neurons, whereas the opposite can be seen for cald KO + cald-GFP. (mean ± SEM, 2-way ANOVA, ***p<0.001 for overall interaction, Bonferroni post-tests: *p<0.05 and **p<0.01 for cald WT vs cald KO + cald-GFP, for absent and permanent protrusions, respectively; ***p<0.001 for cald WT vs cald KO + JPK for absent protrusions; ***p<0.001 for cald KO vs cald KO + cald for permanent protrusions; **p<0.01 for cald KO + cald-GFP vs cald KO + JPK for both absent and permanent protrusions. cald wt, n=13 cells, 3 experiments; cald KO, n=23 cells, 3 experiments; cald KO + cald-GFP, n=11 cells, 2 experiments; cald KO + JPK, n=8 cells, 2 experiments) C Further analysis of the data in (B) for all transiently visited protrusions. In cald WT neurons, roughly 50% of protrusions get visited by an ER only once, while the other half experiences multiple ER entries. This ratio is changed towards multiple ER entries in cald KO neurons, and can be rescued by overexpression of caldendrin-GFP (cald KO + cald), but not by 48 h treatment with 50 nM jasplakinolide (cald KO + JPK). The n of independent experiments, cells and analysed protrusions is the same as in (B).

Figure 3A. Cultured dorsal root ganglion (DRG) neurons from E12.5 Sema6A knockout (KO) embryos were transfected with EGFP, EGFP-tagged wild-type (WT) Sema6A (Sema6A-WT) or different EGFP-tagged Sema6A mutants (Sema6A-mutA, Sema6A-mutB, and Sema6A-mutA+B) at 1 day in vitro (DIV1) and treated with purified Sema6A-Fc at a concentration of 75 nM for 1 hour at 37°C at DIV4. Transfection of EGFP was used as a control (full collapse). DRG neurons from Sema6A KO embryos acquired sensitivity to Sema6A and growth cone collapse was observed in three independent experiments. Transfection of Sema6A-WT, Sema6A-mutA and Sema6A-mutB but not of EGFP or Sema6A-mutantA+B prevented Sema6A-mediated growth cone collapse (Fisher's exact test p<0.0001). Quantification of growth cone collapse was performed using a growth cone morphology matrix (lower part panel A). Data is presented as percentage of morphologically distinct growth cones, divided (represented by the dotted line) in two categories, from uncollapsed (1-4) to fully collapsed (5-8). Totally, 20-40 growth cones were analyzed for each condition per experiment (n=3 experiments). Scale bar 20 µm. B.
