This study analyzes the role of genetic and/or viral factors as etiologic agents in systemic lupus erythematosus in NZB/NZW F1 hybrid mouse, first by a backcross within the NZ strains. A separate study involved an outcross, production of an F2 generation, and then backcross to both NZ parents. The results were assayed by histologic evaluation of renal disease. Assay techniques for anti-DNA and proteinuria showed no evidence for segregation and were not useful. Histology of the kidney showed distinct segregation patterns consistent with the interpretation of the etiology as co-dominant genetic factors. While the virus was not considered etiologic, mechanisms for relating activity to the pathogenesis were discussed.
