The contribution of immunoglobulin class to the histology and ultrastructure of renal lesions were examined in an experimental model of glomerulonephritis in which the glomerular deposits were selected to be predominantly IgM or IgG. The selection was accomplished by immunizing and then injecting rabbits with a carrier preparation plus heat-denatured (HD) DNA (n = 11) or ultraviolet-irradiated (uv) DNA [n = 11). It has been shown previously that HD DNA gives rise to an IgM antibody response and uv DNA to an IgG response. Groups of rabbits immunized with each preparation produced largely IgM (HD DNA) or IgG (uv DNA) anti-DNA antibody. After 10 and 20 weeks of injections, animals receiving both antigens developed diffuse mesangial hypercellularity with either IgM or IgG deposits accompanied by C3; by ultrastructural analysis all deposits were confined to the mesangium. By 28 weeks, heavy mesangial IgM and IgG deposits were noted but no quantitative or qualitative differences in the renal histology was observed. Individual animals developed sporadic hematuria and azotemia but proteinuria was not found. These results show that both IgM and IgG can mediate experimental mesangial proliferative glomerulonephritis and that the immunoglobulin class of the glomerular deposits does not influence the appearance of the renal lesion.
