In addition, we measured the concentrations of plasma cytokines, including IL-35, IL-10, IL-17, tumor necrosis factor (TNF)-α, and interferon (IFN)-γ, and further evaluated their correlations among the abundances of the Breg subsets, the concentrations of plasma cytokines, and other clinical indicators of SLE patients. Here, IFNG is linked to systemic lupus erythematosus.
