The central pathogenetic role of type I interferons (IFNs) in several systemic autoimmune diseases is well established. Recent studies have also discovered a similar crucial role of type I IFNs in different components of metabolic disorders. Self nucleic acid-driven Toll-like receptor (TLR) activation in plasmacytoid dendritic cells (pDCs) and type I IFN induction appear to be the key initiating events shared by most of these autoimmune and metabolic diseases. Further strengthening this link, many patients with systemic autoimmunities also present with metabolic disorders. This concurrence of autoimmunities and metabolic disorders may be explained by a single pathogenetic continuum, and suggests shared targets for potential new therapies.
