Annotation description:Figure 3: Knockdown of PCDH7 changes dendritic spine morphology in dissociated neurons.
"Dissociated neurons were transfected with either scrambled shRNA, or two distinct shRNAs targeting PCDH7 (together with GFP as a marker protein), and morphology and density of dendritic spines were analyzed. Neurons with reduced PCDH7 either by shRNA_A or shRNA_C showed similar phenotype with longer dendritic spines (Fig. 3B,C).

We found that although the total dendritic spine density was not affected by PCDH7 knockdown, there was around 50% reduction in the density of typical spines (length < 2 μm), and about a threefold increase in the density of longer spines (length > 2 μm) (Fig. 3D)."

Figure 4: Knocking down PCDH7 modestly increases dendritic spine length in hippocampal slices with no significant impact on NMDA current.
