Preferential but not exclusive T cell receptor V beta chain utilization of myelin basic protein and peptide-specific T cell clones in mice.
The repertoire of T cell receptor (TCR) V beta chain utilization was investigated in PL/J, CXJ-1, SJL/J and B10.S-->SJL/J chimeric mice in response to either myelin basic protein (MBP) or the strain-specific encephalitogenic peptide. Our analysis showed that there was an overlapping predominance in the TCR V beta gene utilization in the MBP-specific responses, which were independent of the major histocompatibility complex (MHC) class II haplotype present, and the immunodominant peptide region recognized in these different strains. In those mice having the TCR V beta b haplotype (PL/J, CXJ-1, and the B10.S-->SJL chimera) either the TCR V beta 4, 8, and 13 or the TCR V beta 4, 6, and 13 predominated. In contrast, in mice with TCR V beta a haplotype (SJL/J) V beta 4, 6, and 17a were found. However, the quantitative distribution of these preferentially utilized TCR V beta chains in each strain was defined by the MHC class II haplotype and the immunodominant peptide recognized. The expression of the V beta 8 gene product in the peripheral TCR repertoire did not always correlate with predominant V beta 8 utilization in the MBP-specific response.
