title: Myelin/oligodendrocyte glycoprotein-specific T-cells induce severe optic neuritis in the C57BL/6 mouse.
abstract: OBJECTIVE
  The optic nerve is a common site of tissue damage in multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE). To determine the relationship between optic neuritis (ON) and EAE, we examined the incidence of ON in C57BL/6 (B6) mice immunized with a myelin oligodendrocyte/glycoprotein (MOG)-derived peptide or injected with MOG-specific T cells, which are known to induce EAE.
  
  
  METHODS
  Mice were immunized with MOG35-55 or MOG40-54 peptides emulsified in complete Freund's adjuvant (CFA). Pertussis toxin (PTX) was injected intraperitoneally 1 day before and after immunization. For disease induction by adoptive transfer of primed cells, donor C57BL/6 mice were received with T-cell blasts (1-6 x 10(6)/mouse). Both EAE and ON were observed by either clinical signs or histology.
  
  
  RESULTS
  ON developed in a high proportion of B6 mice treated with either protocol. The most severe inflammation was observed in the adoptively transferred mice. The induced ON was most frequently bilateral. In either actively or adoptively transferred diseases, both association and dissociation of EAE and ON was observed.
  
  
  CONCLUSIONS
  Different MOG-specific T-cell subsets might be involved in the pathogenesis of EAE and ON. A better understanding of the pathogenesis of ON after induction by MOG may have important diagnostic and therapeutic implications.
