Brain-Specific SNAP-25 Deletion Leads to Elevated Extracellular Glutamate Level and Schizophrenia-Like Behavior in Mice

<div>Generation of SNAP-25 forebrain-specific KO mice. (a) Targeting strategy used for the deletion of the SNAP-25 exon 4. P1-2 referred to PCR primers for genotyping, which is located on intron flank exon 4 separately. (b) PCR genotyping of recombinant SNAP-25 locus. (c) Western blot analysis of brain extracts of Ctrl and mutant mice. Right panel: quantitative analysis of western blot images. <svg height="8.55521pt" id="M12" style="vertical-align:-0.2063904pt" version="1.1" viewbox="-0.0498162 -8.34882 27.8368 8.55521"
