WARS1 and systemic lupus erythematosus: Integrating our published data set with that of the patients with SLE analyzed in this study, we identified the same population of cells expressing CD274 and high levels of ISGs, including WARS, GBP1, GBP5, IFI30, IFI35, and IFITM3, and termed them “C8” for consistency (Figure 6, D and E, and Supplemental Figure 7).
