Genetics of experimental lupus nephritis: non-H-2 factors determine susceptibility for renal involvement in murine chronic graft-versus-host disease.
Chronic graft-versus-host disease (GvHD) was induced in (C57BL/10 x DBA/2)F1 and (B10.S x DBA/2)F1 hybrids by injection of DBA/2 lymphocytes. All of the animals developed GvHD. Renal disease and proteinuria occurred in all of the (C57BL/10 x DBA/2)F1 hybrids, but only in 54% of the (B10.S x DBA/2)F1. The type of renal lesion was similar in all diseased animals of both strains, i.e., immune complex glomerulonephritis (ICGN) with deposition of antibodies and complement in glomeruli. To find out whether H-2 haplotype or other factors, such as non-H-2 linked genes, determine the susceptibility for renal involvement in GvHD, we produced (B10 x B10.S)F1 x DBA/2 mice, determined their H-2 genotype serologically, and separated them into H-2b/d and H-2s/d groups. These two groups did not differ with respect to susceptibility to renal disease in the course of GvHD, which indicates that H-2 is not the decisive genetic factor. We conclude that factors not linked with H-2 exert a major influence on susceptibility to GvHD-related renal disease in these mice.
