H-2D-restricted cytotoxic lymphocytes in the central nervous system of
B10 mice.

AB Resistance to Theiler's virus-induced demyelination maps genetically to
the MHC class I D region and is associated with up-regulation of class I
products and the presence of MHC-restricted virus-specific cytotoxic
CD8+ T cells in the CNS. To determine the targets of the cytotoxic
response, transfected C57SV (Kb, Db) cells expressing LP (including the
leader peptide, VP4, VP2, and VP3 coding sequences), VP4 (including the
leader peptide and VP4), VP2, VP3, VP1, or RP (including P2 and P3) were
generated. CNS-infiltrating lymphocytes obtained from virus-infected
B10, B10.K (Kk, Dk), B10.RBF (Kb, Df). B10.RFB3 (Kf, Db), and B10.RBQ
(Kb, Dq) mice were used as effectors. Specific cytotoxicity to the
capsid proteins encoded in the LP construct, VP2 and VP1, was
demonstrated to be H-2Db region restricted and was mediated by CD8+ T
cells. No Kb-restricted virus-specific cytotoxicity response was
observed. No specific cytotoxic response against RP-encoded proteins was
observed in the CNS of B10 mice. Therefore, both VP1 and VP2 are targets
for an H-2D-restricted cytotoxic immune response against Theiler's virus
infection in the CNS of infected resistant B10 mice.
