Various T cell and B cell targets could provide potential therapies, including interleukins 12 and 23 and CD19 and CD20, among others.
Innate immune system activation with type 1 interferon as a key mediator and the adaptive immune system that results in autoantibody production both suggest potential therapeutic targets.
Ultimately, Dr. Crow believes combination therapies hold the key to effective lupus treatments in the future. Combination therapies that target the interferon pathway, autoantibody production and effector macrophages may provide better treatment options. Dr. Crow advised rheumatologists not to get too discouraged if one potential SLE treatment does not appear to work, because combination therapy likely will be the more effective route.
