Removal of Dnmt1 enzyme during OPC differentiation could lead to neurological symptoms

The removal of the enzyme Dnmt1 during oligodendrocyte progenitor cell (OPC) differentiation in the central nervous system resulted in inefficient myelin formation and neurological deterioration, including loss of control of bodily movements, in mice, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published today in the medical journal Cell Reports. The results could lead to a new understanding of multiple sclerosis and other myelin disorders in humans.
