| abstractText | Autoimmune-prone NZB mice mainly produce IgM-class anti-DNA antibodies and mild SLE develops later in life. The F1 hybrid of NZB and non-autoimmune NZW mice (NZB/W F1 mice) develop a more fulminant SLE, associated with decreases in IgM class, and, in turn, increases in IgG class anti-DNA antibodies. To elucidate the role of the H-2 complex in this mode of anti-DNA antibody production, we established and studied H-2-congenic New Zealand mice, i.e. NZB, NZW, and NZB/W F1 mice with either the homozygous H-2z/H-2z or H-2d/H-2d haplotype or the heterozygous H-2d/H-2z haplotype. The data showed that: (i) although the non-H-2-linked NZB gene(s) seems to determine the IgM anti-DNA antibody production in NZB mice, the effect of this gene is fully expressed only in the case of the H-2d/H-2d homozygous state. (ii) The production of IgG anti-DNA antibodies observed in NZB/W F1 hybrid mice is restricted to the H-2d/H-2z heterozygosity. (iii) Because both NZB and NZW mice with the H-2d/H-2z haplotype produce a lower titer of IgG anti-DNA antibodies than do the NZB/W F1 mice, other complementary non-H-2-linked genetic elements from both NZB and NZW parents are required. The development of lupus nephritis correlated well with that of anti-DNA antibodies. Thus, H-2d/H-2z heterozygosity is a necessary but not sufficient condition for the development of autoimmunity in NZB/W F1 mice.(ABSTRACT TRUNCATED AT 250 WORDS) |
