These were similar to CD19+, CD14+, CD11b+, CD11c+ cells, where the proportion of CD19+, CD14+, CD11b+, CD11c+ cells was higher in SLE patients (Figure S2A), and proportion of CD19+BTN3A1+, CD14+BTN3A1+, CD11b+BTN3A1+, CD11c+BTN3A1+ cells was significantly higher in SLE patients compared with healthy controls, respectively (Figure S2B). Here, ITGAX is linked to systemic lupus erythematosus.
