By the RNA sequencing of the hippocampus in normal or depressed mice with or without d-mannose administration, we found that the expression of SCFA transporter SLC5A8, which preferentially transports butyrate [44], but not MCT1, MCT2, and MCT4, was remarkedly decreased in CRS-exposed mice compared with normal mice (Fig. 7H). The gene discussed is SLC16A7; the disease is congenital rubella syndrome.
