Western blot analysis showed that CRS significantly increased the expression of NMDARs containing GluN2A (p < 0.001, Figures 4(a) and 4(b)) and GluN2B (p < 0.001, Figures 4(c) and 4(d)) in the frontal cortex of mice subjected to 16-day CRS. This evidence concerns the gene GRIN2A and congenital rubella syndrome.
