This study takes advantage of the predominant usage of V-beta-8.2 by the TCRs of encephalitogenic T cells specific for myelin basic protein. Vaccinia virus recombinants expressing V-beta-8.2 (VV-beta-8.2) and V-beta-3 (VV-beta-3) proteins were constructed, and their abilities to confer protection against experimental autoimmune encephalomyelitis (EAE) induction in H-2-u mice were examined. Mice immunized with VV-beta-8.2 developed very mild EAE by comparison with mice that were vaccinated with VV-beta-3, which developed severe clinical symptoms. This reduction in EAE correlated with a diminished T cell proliferative response to myelin basic protein in the mice that received VV-beta-8.2 compared with that in mice receiving VV-beta-3.
