E-mail: hjanders@med.uni-muenchen.de <h3>SPECIFIC AIMS</h3> It has been demonstrated that interaction of bacterial CpG-DNA with toll-like receptor (TLR) -9 on B cells stimulates autoantibody secretion, which might contribute to the pathogenesis of systemic lupus erythematosus. We investigated the effects of exogenous CpG-oligodeoxynucleotides (ODN) or DNA derived from Escherichia coli on systemic autoimmunity in nephritic MRL lpr/lpr mice 16–18 wk of age. <h3>PRINCIPAL FINDINGS</h3> 1. E. coli DNA and CpG-ODN increase serum DNA autoantibodies in MRL lpr/lpr mice We investigated the effects of bacterial DNA or CpG-ODN on anti-DNA IgG 2a and
