Effect of glutamate antagonists, CNQX or APV, on S-SCAM overexpression-induced loss of GABAA receptor clusters. (a) Representative GABAAR γ2 and vGAT immunocytochemical images of hippocampal neurons transfected with DsRed or myc-S-SCAM treated with either DMSO (Control), APV (100 μM), or CNQX (50 μM). (b) Quantification of the glutamate antagonist effects on GABAAR γ2 clusters. n = 26 (DsRed, Control), 23 (DsRed, CNQX), 24 (DsRed, APV), 30 (S-SCAM, Control), 22 (S-SCAM, APV), 30 (S-SCAM, CNQX). Two-way ANOVA, interaction F(2,149) = 6.989, p = 0.0013, treatment group F(1,149) = 32.85, p < 0.0001, construct group F(2,149) = 4.959, p = 0.0082, Tukey’s post-hoc test. Scale bars, 5 μm.
