Previous studies have indicated that the NZW, DBA/1, 129/sv and BUB strains are particularly sensitive to experimental anti-glomerular basement membrane (GBM)-induced immune nephritis. The present study extends previous observations by examining eight additional inbred mouse strains for their susceptibility to immune nephritis. Unlike the ALR/Lt, CAST/Ei, DDY/JclSidSeyFrk, FVB/NJ, PERA/Ei, SB/Le and BALB/c strains, the C58 mouse strain was observed to be particularly susceptible to experimental immune nephritis, with CBA mice being a close second. In contrast to the other strains, C58 mice uniformly developed heavy proteinuria, azotemia and severe glomerulonephritis with prominent crescent formation and tubulointerstitial nephritis following challenge with anti-GBM sera. These differences were associated with increased murine Ig deposition, leukocyte infiltration and IFN-
production within the kidneys of C58 mice. Studies aimed at elucidating the genetic factors and molecular pathways responsible for the enhanced renal disease in C58 mice are warranted.
