Two weeks before PTSD modeling, we selectively overexpressed MAOB in the IL cortex astrocyte of MAOB null knockout (MAOB-KO)35 mice using the AAV-GFAP::MAOB-EGFP virus in IL of PTSD-like mouse, creating the MAOB-overexpression (MAOB-OE) + PTSD group (Fig. 6q). This evidence concerns the gene GFAP and post-traumatic stress disorder.
