Considering all of the “common” IFN signature genes (FC ≥2 or ≤−2 in SLE), 76 of 94 “common” IFN signature probes (81%) in the CD4+ T cells (Table S1), 120 of 165 “common” IFN signature probes (73%) in the CD16− monocytes (Table S2) and 145 of 173 “common” IFN signature probes (84%) in the CD16+ monocytes (Table S3) showed higher expression levels with larger FCs in the SLE patients than in the immunised ND. The gene discussed is IFNA1; the disease is systemic lupus erythematosus.
