a Coimmunoprecipitation of IRF8 and STING SAVI mutants in HEK293T cells. Cells were transfected with the indicated plasmids for 20 h followed by coimmunoprecipitation and immunoblotting analysis with the indicated antibodies. b Profiling analysis of IRF8 expression in healthy donors and patients with autoimmune diseases. Graph shows mean ± SEM, n = 5–15 independent samples. Data were analyzed by unpaired two-tailed Student’s t-test. c Immunoblotting analysis of IRF8S151 and STINGS366 in PBMCs from healthy donors (n = 11 independent samples) and SLE patients (n = 10 independent samples). Relative phosphorylation abundance of IRF8S151 and STINGS366 relative to β-actin was quantitated. Data were analyzed by unpaired two-tailed Student’s t test. d qPCR analysis of Ifnb1, Cxcl10, Il6 and Il1b mRNA levels in WT or Trex1−/− BMDMs and BMDCs with or without additional Irf8 knockout by CRISP-Cas9. Data are presented as mean, n = 2 technical repeats. Data were analyzed by unpaired two-tailed Student’s t test. Source data are provided as a Source data file.
