As for chemokine and chemokine receptor, VDR expression was positively correlated with C-C motif chemokine ligand 2 (CCL2), C-C motif chemokine receptor 1 (CCR1), C-C motif chemokine receptor 2 (CCR2), and C-C motif chemokine receptor 5 (CCR5) in GBM or C-C chemokine ligand 22 (CCL22), C-X-C motif chemokine ligand 16 (CXCL16) in TGCT (Figure 5D,E). This evidence concerns the gene CCR2 and glioblastoma.
