CCL3 and primary cutaneous T-cell non-Hodgkin lymphoma: In addition, the results demonstrated a positive correlation for CCL3 and CCL4 with CD163 (Spearman’s correlation coefficient: r = 0.68, P < 0.0001, n = 45; r = 0.56, P < 0.0003, n = 45; Figure 3D), but not for CCL2 (Supplemental Figure 3B), suggesting that CCL3 and CCL4 may facilitate the recruitment and infiltration of M2-like TAMs in CTCL.
