Abstract
- Type I interferon (IFN) is produced by the innate immune system in several autoimmune diseases, such as systemic lupus erythematosus (SLE), polymyositis, and systemic sclerosis. In these diseases, immune complex (IC)-containing DNA or RNA may act as endogenous IFN inducers. The abilities of these IC to reach the endosomes in the plasmacytoid dendritic cells (PDC) cause the intracellular toll-like receptor (TLR) to initiate a cascade of transcription factors--a critical step in triggering type I IFN production. A special configuration of the nucleic acid (NA), such as CpG-rich non-methylated DNA or GU-rich RNA, appears crucial. However, other components of the IC, like HMGB1, may also be necessary. Studies regarding the genetic background of autoimmune diseases suggest that variants of genes involved in both IFN production and response are associated with disease susceptibility. This knowledge is important for the development of new therapeutic strategies in autoimmune diseases.
