The data showed that the expression levels of CCL8 (P = 0.016) and CD163 (P = 0.048) were obviously higher in DLBCL tissues compared to normal tissues, while there was no significant difference in LILRB2 (P = 0.788), C1QB (P = 0.556), and CD3G (P = 0.250) (Figures 6A, B, Supplemental Figures 2A–C). This evidence concerns the gene C1QB and diffuse large B-cell lymphoma.
