| Abstract: | The pathogenesis of the spontaneous glomerulonephritis of NZB and (NZB x NZW) F1 hybrid mice is related at least in part to the formation of natural antibody against antigens of the G (Gross) system, and apparently to the deposition in the glomeruli of immune complexes of G natural antibody with G soluble antigen (GSA), type-specific antigen specified by wild-type Gross leukemia virus. G natural antibody and GSA are detectable in the acid-buffer eluate of the kidneys of NZB mice during the course of the glomerulonephritis. (NZB x NZW) F1 hybrid mice develop glomerulonephritis and produce GSA and free G natural antibody earlier in life than do NZB mice. The proteinuria manifestation of the gomerulonephritis of (NZB x NZW) F1 hybrid mice becomes increasingly prevalent as GSA undergoes immune elimination from the circulation. Gross leukemia virus-specified antigens together with bound immunoglobulins are located in the glomerular lesions of (NZB x NZW) F1 hybrid mice, both in the mesangium as observed in NZB mice and also in the wall of the peripheral capillary loops of the glomeruli. |
