Measurement of changes in synaptic markers with phytocannabinoid treatments. (A–D) Expression levels in hippocampi of treated females (left) and males (middle), with representative western blots on the right. (A) Comparison of VGAT expression across treatment groups. (B) Expression levels for Syn, a calcium-sensing protein in the presynapse. (C) PSD95 expression across treatment groups. (D) Comparison of VGlut2 across treatment groups. A one-way ANOVA with multiple comparisons and Tukey's post hoc test was used in analyses; n=7–9. Error bars represent 95% confidence interval. VGAT, vesicular GABA transporter; PSD95, postsynaptic density protein 95; Syn, synaptobrevin; VGlut2, vesicular glutamate transporter 2.
