title: Adoptively transferred CD8+ T lymphocytes provide protection against TMEV-induced demyelinating disease in BALB/c mice.
abstract: On intracerebral infection with the BeAn strain of Theiler's murine encephalomyelitis virus (TMEV), certain mouse strains develop a chronic demyelinating disease similar both clinically and pathologically to human multiple sclerosis. Other strains remain resistant. We previously established that differential susceptibility to this demyelinating disease exists among BALB/c substrains, with BALB/cAnNCr mice being susceptible while BALB/cByJ mice are resistant. BALB/cByJ mice are rendered susceptible to TMEV-induced demyelination on exposure to low dose gamma-irradiation before TMEV infection. BALB/cAnNCr and irradiated, infected BALB/cByJ animals are protected against TMEV-induced demyelination by the transfer of a splenic population from TMEV-infected BALB/cByJ donors. Resistance to demyelination appears to be mediated by a CD8+ radiosensitive population, which is induced on infection with TMEV and which must act early to establish resistance to TMEV-induced demyelination.
