A, Western blots showing bands for gephyrin, VGAT, GABAAγ2, and actin in hippocampal membrane fractions from mice receiving stereotaxic injections of the AAV-NLGN2 or AAV-mCherry vectors into the hippocampus. B, Total membrane levels of gephyrin were significantly increased after transduction with the AAV-NLGN2 vector, compared to the AAV-mCherry vector (p=0.032, Student’s t-test). C, Total membrane levels of VGAT protein were significantly increased after transduction with the AAV-NLGN2 vector, compared to the AAV-mCherry vector (p=0.0097, Student’s t-test). D, Total membrane levels of GABAAγ2 were significantly increased after transduction with AAV-NLGN2, compared to the AAV-mCherry vector (p=0.016, Student’s t-test).
