Research Abstract

I have found that time-specific effects of poly (I:C), which mimic a bacterial and viral infections, on methyltransferases in the brain of embryos in a part-specific manner.Additionally, the expressions of some candidate genes for autism change part-specific manner, and these genes are identified as viral infection susceptibility genes.
