Differences in expression of lupus nephritis in New Zealand mixed H-2z homozygous inbred strains of mice derived from New Zealand black and New Zealand white mice. Origins and initial characterization.

Abstract

The NZM strains of mice are a unique set of inbred strains that have inherited various genomic segments of the two parental strains that lead to phenotypic differences in disease expression. These results indicate that the previously proposed strict requirement for H-2 heterozygosity for the development of nephritis in the (NZB x NZW)F1 hybrid mice may not be valid. It is assumed that both the Lpn-1 locus of NZB and the Lpn-2 locus of NZW and a sufficient number of other disease-associated genes of both ancestral strains have been recombined in these new strains to produce the various patterns of renal disease.
