Figure Lengend Snippet: Cytokines in serum and bone tissue of rats in each group. BMP‐2, VEGF, TGF‐β1 and IL‐10 of 5% PI group are lower than other groups, while IL‐6 is higher than other groups at 1 and 2 weeks. BMP‐2, VEGF, TGF‐β1 and IL‐10 of 2.5% PI group and 0.5 PI group are higher than other groups, while IL‐6 is lower than other groups at 1 and 2 weeks. * p < 0.05.

Figure Lengend Snippet: ( A ) Western blot analysis of the expression of Sema 3 A, L1CAM and the Sema 3 A receptors Nrp1 and Plexin A1 in the cortex of PND1 control and AnkB440 KO mice. ( B ) Quantification of protein levels normalized to actin in cortical lysates from PND1 mice of indicated genotypes relative to the normalized levels of each protein in control brains. Data show mean ± SEM for three biological replicates per genotype for one experiment. Unpaired t test. *p < 0.05. ( C ) Western blot analysis of total and surface levels of indicated proteins in DIV3 control and AnkB440 KO cortical neurons. ( D ) Quantification of total and surface protein levels normalized to actin relative to the normalized levels of each protein in control cortical neurons. Data show mean ± SEM for three biological replicates per genotype for one experiment. Unpaired t test. **p < 0.01. ( E ) Images show PLA signal between L1CAM and Nrp1 at the cell surface of the axon and GCs of DIV3 cortical neurons from the indicated genotypes. This assay used an Nrp1 antibody that selectively recognizes an extracellular epitope. Phalloidin staining was used to identify GCs. Scale bar, 2 μm. ( F ) Quantification of PLA signal at the GC surface relative to GC area collected from an average n = 15 GCs/genotype. The box and whisker plots represent all data points arranged from minimum to maximum. One-way ANOVA with Tukey’s post hoc analysis test for multiple comparisons. ****p < 0.0001. ( G ) Images show Nrp1 localization at the surface of GCs of DIV3 neurons untreated and treated with Sema 3 A, which induces the internalization of surface Nrp1. Scale bar, 1 μm. ( H ) Quantification of surface Nrp1 levels at GCs relative to GC area at the basal state and upon Sema 3A-induced Nrp1 internalization. Data represent mean ± SEM collected from an average of n = 90 GCs/treatment/genotype/experiment. Each dot represents one out of three independent experiments. One-way ANOVA with Tukey’s post hoc analysis test for multiple comparisons. **p < 0.01. Figure 7—source data 1. AnkB440 stabilizes the L1CAM-Nrp1 complex at the cell surface of GCs.

Article Snippet: Detection of surface Nrp1 by immunofluorescence was conducted using rabbit anti-Nrp1 extracellular antibody (1:50, # ANR-063, Alomone) that recognizes amino acid residues 502–514 in the extracellular N-terminus of Nrp1.

Figure Lengend Snippet: AnkB440 binds the cytoplasmic domain of L1CAM to stabilize the L1CAM-Nrp1 holoreceptor complex at the cell surface. Transduction of Sema 3 A signals via the AnkB440-L1CAM-Nrp1 complex modulates F-actin dynamics through LIMK phosphorylation of cofilin to facilitate local F-actin disassembly and the collapse of GCs from the axon and collateral branches independently of βII-spectrin, or of AnkB440 interaction with microtubules. Source data . Source data contain the original files of the full raw unedited gels or blots and figures with the uncropped gels or blots with the relevant bands clearly labelled. Source data files also include numerical data that are represented as graphs in the figures.
