Studies of tolerance to DNA in NZB/NZW F1 mice.
Administration of sDNA-poly-D-lysine (DNA-PDL) to newborn NZB/NZW F1 mice (B/W) was previously shown to prolonge survival and to decrease nephritis and DNA antibodies. In this study, B/W mice treated from birth with DNA-PDL were found to be tolerant to immunization with sDNA on PDL or mBSA carriers in  adjuvants. Tolerance to sDNA was present and was hapten-specific carrier-dependent. IgG and IgM anti-nDNA circulating antibodies were suppressed. Continuous tolerization was necessary to maintain tolerance. Tolerance to sDNA could be transferred by spleen cells, by tolerized thymus cells, and by tolerized bone marrow cells, suggesting that both T and B cells participated in this phenomenon.
