The VitD receptor (VDR) is expressed in neural stem cells (NSC) (de la Fuente et al., 2015), OPC (Baas et al., 2000; Eyles, Smith, Kinobe, Hewison, & McGrath, 2005), and oligodendrocytes (Eyles et al., 2005), and VDR expression is elevated in MS demyelinating plaques. This evidence concerns the gene VDR and myeloid sarcoma.
