An Update on Autoinflammatory Diseases: Interferonopathies

Abstract

Purpose of Review: Type I interferons (IFNαβ) induce the expression of hundreds of genes; thus, it is unsurprising that the initiation, transmission, and resolution of the IFNαβ-mediated immune response is tightly controlled. Mutations that alter nucleic acid processing and recognition, ablate IFNαβ-specific negative feedback mechanisms, or result in dysfunction of the proteasome system can all induce pathogenic IFNαβ signalling and are the focus of this review. Recent Findings: Recent advances have delineated the precise cytoplasmic mechanisms that facilitate self-DNA to be recognised by cGAS and self-RNA to be recognised by RIG-I or MDA-5. This helps clarify interferonopathies associated w..
