  1. Acute MS Marburg type of acute MS, Progr. MS primary or secondary progressive MS, Case HAE human autoimmune encephalitis, described in this study, Marmoset MOG EAE chronic EAE induced in marmosets by active sensitization with recombinant myelin oligodendrocyte glycoprotein in incomplete Freund’s adjuvant, Mouse MOG EAE chronic EAE in C57Bl6 mice induced by active sensitization with MOG35–55 peptide
  2. Yesa: white matter lesions in chronic mouse EAE are mainly due to massive axonal destruction and secondary demyelination
  3. Mod moderate, mild mild, few(iron) only few cells in lesions with high iron content
