MAPT and congenital rubella syndrome: To reveal whether MEM treatment also affects the phosphorylation of tau for mice without CRS stimulation, mice without CRS were treated with MEM in doses of 5 and 10 mg/kg for 16 consecutive days; Western blotting showed that treatment with MEM in doses of 5 and 10 mg/kg for 16 consecutive days caused a tendency to increase the tau phosphorylation at the AT8 epitope but had no statistical significance.
