Abstract
The specificities of anti-RNA antibodies of diverse origin were studied by inhibition of the binding of radioative polyinosinic polycytidylic acid. The antibodies were from human patients with systemic lupus erythematosus (SLE), older NZB/NZW F1 mice who have SLE, and young NZB/NZW F1 mice immunized with either synthetic or viral double-stranded (ds) RNA. The inhibitors were two viral ds and two synthetic ds RNAs, ribosomal RNA and transfer RNA. The human sera were more heterogeneous than the mouse lupus sera, and had greatest specificity for reovirus RNA. The mouse lupus sera were more homogeneous and, in general, were inhibited efficiently by all four ds RNAs. Sera from mice immunized with synthetic RNA reacted poorly with viral RNA, whereas sera from mice immunized with viral RNA reacted with all four ds RNAs and resembled the lupus sera. These results suggest a role for viruses in the induction of anti-RNA antibodies, and are compatible with the concept that virus infection as well as excessive antibody responses are involved in the pathogenesis of SLE.
