Emerging evidence supports that mitochondrial dysfunction contributes to Systemic Lupus Erythematosus (SLE) pathogenesis. Here we show that programmed mitochondrial removal, a hallmark of mammalian erythropoiesis, is defective in SLE. Specifically, we demonstrate that during human erythroid cell maturation, a hypoxia-inducible factor (HIF)-mediated metabolic switch is responsible for the activation of the ubiquiting proteasome system (UPS), which precedes and its necessary for the autophagic removal of mitochondria. A defect in this pathway leads to accumulation of red blood cells (RBCs) carrying mitochondria (Mito+ RBCs) in SLE patients and in correlation with disease activity. Antibody-mediated internalization of Mito+ RBCs induces Type I interferon (IFN) production through activation of cGAS in macrophages (M⏀). Accordingly, SLE patients carrying both Mito+ RBCs and opsonizing antibodies display the highest levels of blood Interferon Stimulated Gene (ISG) signatures, a distinctive feature of SLE. A subgroup of SLE patients fail to engage HIF regulated metabolic and proteasomal pathways causing the accumulation of mitochondria-containing red blood cells. These cells, when engulfed by macrophages activate cGAS/STING dependent inflammation.
