Opposing Impact of B Cell–Intrinsic TLR7 and TLR9 Signals on Autoantibody Repertoire and Systemic Inflammation
8 Apr 2014
Abstract excerpt
Systemic lupus erythematosus is a multisystem autoimmune disease characterized by autoantibodies targeting nucleic acid-associated Ags. The endosomal TLRs TLR7 and TLR9 are critical for generation of Abs targeting RNA- or DNA-associated Ags, respectively. In murine lupus models, deletion of TLR7 limits autoimmune inflammation, whereas deletion of TLR9 exacerbates disease. Whether B cell or myeloid TLR7/TLR9...
