Research Abstract |
As compared with the NZB strain, NZB x NZW F1 (B/W F1) hybrid mice show a much earlier onset and a higher incidence of renal disease, associated with markedly increased serum levels of anti-DNA antibodies. The increment of anti-DNA antibodies is mainly due to the increase in IgG class antibodies. These events in the B/W F1 mice can be attributed to the contribution of genes derived from both NZB and nonautoimmune NZW strains. Our studies using H-2 congenic New Zealand mice suggested that both H-2^d from NZB mice and H-2^z from NZW mice were required for IgG anti-DNA antibody production in B/W F1 mice. Our data also suggested that the gene linked to the T cell receptor beta chain gene complex of NZW has an important role in this event. The in vitro studies revealed that IgG anti-DNA antibody production in B/W F1 mice is strictly dependent on the interaction of antibody producing B cells and CD4^+ helper T cells. Together with these genetical and cellular studies, it is strongly suggested that the interplay between the hybrid Ia molecules derived from both NZB and NZW on B cells and T cell receptor from NZW may be essential for the production of IgG anti-DNA antibodies in B/W F1 mice. The requirement of H-2 heterozygosity for IgG anti-DNA antibody production was confirmed by the studies using H-2 congenic New Zealand mice, which we have already established. We are now trying to establish T cell receptor beta chain congenic New Zealand mice and to confirm the important role of T cell receptor for IgG anti-DNA antibody production in both in vivo and in vitro systems.
