Immature cell populations and an erythropoiesis gene expression signature in systemic juvenile idiopathic arthritis: Implications for pathogenesis

Objective. Previous observations suggest that active systemic juvenile idiopathic arthritis (sJIA) is associated with a prominent erythropoiesis gene expression signature. The aim of this study was to determine the association of this signature with peripheral blood mononuclear cell (PBMC) subpopulations and its specificity for sJIA as compared to related conditions.
