Specifically, Dlg1 cKO mice (Dlg1f/f; CX3CR1creER) and their control littermates (Dlg1f/f, term as Dlg1 f/f) were subjected to tamoxifen at 6 weeks of age to induce microglia-specific knockout of Dlg1. These mice were then randomly assigned to either the control or CRS group. Here, DLG1 is linked to congenital rubella syndrome.
