Type I interferon has a crucial role in the immunopathogenesis of systemic lupus erythematosus (SLE). Analysis of CD4+ T cells from individuals with SLE now shows that type I interferon intervenes with the transcriptional regulators AHR and JUN to downregulate expression of IL-22, which promotes tissue regeneration, and upregulate the expression of CXCL13, which supports lymphoid structure formation.
