  • Title: The role of H-2 in apoferritin-induced murine immune complex glomerulonephritis.

    Abstract:
    The role of the major histocompatibility complex in the development of apoferritin induced immune complex glomerulonephritis was studied in H-2 congenic B10 mice. The glomerular lesions varied strikingly among the three different strains studied. The B10 (H-2b) mice had minimal mesangial expansion or no lesions at all. The B10.BR (H-2k) mice had mesangial expansion and proliferative glomerulonephritis without crescents or interstitial mononuclear cell infiltration. In contrast, the B10.D2 (H-2d) mice had necrotizing glomerulonephritis with crescents and an interstitial mononuclear cell infiltrate. Immunofluorescence and electron microscopy demonstrated only minimal mesangial deposits in B10 (H-2b) mice, predominantly mesangial deposition in the B10.BR (H-2k) mice, and mesangial and subepithelial immune complex deposits in B10.D2 (H-2d) mice. These morphologic differences correlated with functional abnormalities. Only the B10.D2 (H-2d) mice developed proteinuria, hematuria, and elevated blood urea nitrogen. They also had the most elevated antiapoferritin IgG levels. These experiments demonstrate that differences in the pathologic lesions and susceptibility to immune complex glomerulonephritis can be seen in animals that differ only at the H-2 locus. This model will lend itself to the study of the mechanisms by which the major histocompatibility complex influences the development of immune complex glomerulonephritis.
