Systemic lupus erythematosus (SLE) is an autoimmune disease with multiple and heterogeneous clinical manifestations (e.g., skin lesions, kidney damage, neuropsychiatric dysfunction), that primarily affects women and whose etiology remains unclear. Various therapies that regulate and reduce the immune system activity are in use or are being developed; however, many of them have serious side effects. Therefore, new approaches are needed to maximize remission periods and reduce associated side effects. In this review, we summarize the currently recommended therapeutic strategies. Furthermore, we hypothesize that the combined use of drugs targeting various dysregulated cellular processes in SLE (i.e., cytokine production, neutrophil extracellular traps (NETs), phagocytosis) might have therapeutic potential, at least in some disease phenotypes. Preliminary data show that Toll-like receptors 7/8 (TLR 7/8) inhibition (e.g., Enpatoran) may reduce interferon-α (IFN-α) production by monocytes and NET formation by neutrophils. Our hypothesis is that future therapies combining compounds that modulate the three cellular processes might result in a better disease management as current therapies.
