The results of Western blotting showed that the expression of PSD-95 and synaptophysin in the CA1, DG and CA3 regions of dHIP (n = 10–9) (Figures 3A–C) and vHIP (n = 10–9) (Figures 3D–F) were significantly reduced after CRS exposure. The gene discussed is DLG4; the disease is congenital rubella syndrome.
