Hypomyelination following deletion of <i>Tsc2</i> in oligodendrocyte precursors

Abstract

Our findings support a known role of mTOR signaling in regulation of myelination and demonstrate that increased mTORC1 activity early in development within oligodendrocytes results in hypomyelination and not hypermyelination. Our data further support a dissociation between decreased Akt activity and increased mTORC1 activity toward hypomyelination. Thus, therapies promoting activation of Akt-dependent pathways while reducing mTORC1 activity may prove beneficial in treatment of human disease.
