We further did an analysis of the correlation between serum levels of CXCL9 and CXCL10 (Figure 2A), CXCL9 and CXCL11 (Figure 2B), as well as CXCL10 and CXCL11 (Figure 2C) in 160 SLE patients, including those with and without concurrent LN. This evidence concerns the gene CXCL10 and systemic lupus erythematosus.
