Moreover, at 50 ng/ml IFN-λ1, the generation levels of chemokines IP-10 and MIG in SLE patients were more than normal controls (P = 0.02, Figure 5a; P = 0.031, Figure 5b), and the secretion levels of IL-8 were lower in SLE patients than normal controls (P = 0.007, Figure 5c). Here, CXCL9 is linked to systemic lupus erythematosus.
