As a positive control for the validity of myelin staining using the above technique, we utilized spinal cords of mice immunized with the oligodendrocyte antigen, MOG, in the experimental autoimmune encephalomyelitis (EAE) model (Supplementary Fig. 1) and observed a clear disruption of myelin staining corresponding precisely to the loci of immune infiltrates in the spinal cord (Fig. 4c), which are characteristic to EAE. The gene discussed is MOG; the disease is experimental autoimmune encephalomyelitis.
