Outline of Final Research Achievements |
Rett syndrome (RTT) is a neurodevelopmetal disorder associated with mutations in the methyl-CpG-binding protein 2 (MeCP2) gene. Mecp2-deficient ES/iPS cells provide a powerful research tool for disease mechanism studies of RTT. In this study, we found that RTT model (Mecp2-null) ESCs could differentiate into astroglia, oligodendrocyte, and microglia. These results suggest that MeCP2 is not essential for induction of glial cell differentiation. Quantitative RT-PCR analysis revealed that some of microglia marker and cytokine signal genes were lower in Mecp2-null mice than in wild-type mice. These results indicate that loss of MeCP2 leads, either directly or indirectly, to transcriptional dysregulation of these genes in the differentiating microglia. In addition, to confirm the effects of MeCP2 deficiency on microglia function, we investigated the cytokine response and the phagocytic activity of the microglia derived from the wild-type or Mecp2-null cultures.
