 AB    Intravenous infection with Theiler's virus strain GD VII causes acute
       encephalomyelitis in mice. Endogenous IFN-gamma produced in the spinal
       cord is important to protect the tissue in mice infected with this
       virus. Neither CD4+ cells nor CD8+ cells infiltrated the spinal cords of
       infected mice until Day 9 postinfection. However, the number of
       CD3+/TCR-gamma delta+ cells increased in the spinal cords of mice
       infected with the virus. These cells resided in the spinal cords of
       normal mice, and produced IFN-gamma as a result of stimulation by
       immobilized anti-CD3 mAb. Elimination of CD3+ cells by the
       administration of a specific mAb augmented viral replication and
       suppressed production of endogenous IFN-gamma. Depletion of TCR-alpha
       beta+ cells and ASGM1+ cells did not affect the viral replication, and
       did not alter the production of IFN-gamma. Therefore, CD3+/TCR-alpha
       beta- cells producing IFN-gamma play an important role in the protection
       of the spinal cord against Theiler's virus infection. These results
       suggest that CD3+/TCR-alpha beta- cells might be identical to TCR-gamma
       delta+ cells.
