The human CMV-UL86 peptide 981-1003 shares a crossreactive T-cell epitope with the encephalitogenic MOG peptide 34-56, but lacks the capacity to induce EAE in rhesus monkeys
Journal of Neuroimmunology , Volume 182 - Issue 1-2 p. 135- 152
Rhesus monkeys immunized with MOG34-56, a dominant T-cell epitope from myelin/oligodendrocyte glycoprotein, develop an acute neurological disease resembling acute disseminated encephalomyelitis (ADEM) in humans. The typical large demyelinated lesions and mononuclear infiltrates in the monkey brains are caused by MOG34-56T-cells. We show that MOG34-56-reactive CD4+ and CD8+ T-cells are induced in monkeys immunized with a peptide from the human CMV major capsid protein (UL86; 981-1003), that shares sequence similarity with MOG34-56. Monkeys sensitized against the viral peptide and subsequently challenged with MOG34-56display histological signs of encephalitis, but do not show overt neurological signs.
