title: Effects of the major histocompatibility complex loci and T-cell receptor beta-chain repertoire on Theiler's virus-induced demyelinating disease.
abstract: We have investigated the potential effects of H-2 and T-cell receptor (TCR) V beta family genes on induction of T-cell immunity and susceptibility to virally induced demyelinating disease by using BALB.S (H-2K(s)A(s)D(s)) and BALB.S 3 R (H-2K(s)A(s)D(d)/L(d)) mice. These parameters were compared with those of highly susceptible SJL/J (H-2K(s)A(s)D(s)) mice that contain only one-half of TCR V beta family genes compared with the above-mentioned strains. Our results demonstrate that BALB.S but not BALB.S 3 R mice are susceptible similar to SJL/J mice. Although the level of CD4(+) T-cell infiltration to the CNS was elevated in susceptible mice, virus-specific immune responses restricted with H-2(s) were similar in these mice. No preferential use of V beta families associated with differences in the major histocompatibility complex (MHC) components was apparent. However, the pattern and sequence of CDR 3 distribution shows T-cell clonal accumulation in the CNS associated with the H-2 components. Further anti-CD8 antibody treatment of resistant BALB.S 3 R mice abrogated resistance to demyelinating disease, indicating that CD8(+) T cells restricted with H-2D(d)/L(d) are most likely to exert resistance in BALB.S 3 R mice. These studies indicated that TCR V beta and MHC class II genes are the secondary to a particular MHC class I gene expression in susceptibility to virally induced demyelinating disease.
