| Research Abstract |
This study attempted to elucidate the polygenic genetic resistance of a wild mice-derived inbred strain MSM/Ms, having a larger gene pools than commonly used laboratory mouse strains, to glomerulonephritis in an MRL/Mp-lpr/lpr (MRL-Fas^<lpr>) lupus strain of mice and thereby to understand the steps controlling development of lupus nephritis. A genome wide scan for glomerulonephritis resistance loci in a dominant inheritance form was carried out by using MRL-Fas^<lpr> x (MRL-Fas^<lpr> x MSM/Ms) F1 backcross mice. Three dominant MSM/Ms resistance loci were mapped on chromosomes 2, 13 and 4. One of the candidate genes for the locus Agnmrl was Cd59a, encoding an glycosyl phosphatidylinositol-anchored glycoprotein inhibiting the membrane attack complex of complement. Expression of Cd59a in the glomeruli was higher in MSM/Ms than in MRL-Fas^<lpr>. Different transcriptional activity of the Cd59a promoter region was observed between the parental strains of mice. Then, the recombinant congenic strain of mice MRL-Fas^<lpr>-Cd59a^<MSM> was newly established, which was significantly decreased in severity of glomerulonephritis and also renal vasculitis.
