Transcriptional analysis showed that compared to normal T-cells, C-C motif chemokine ligand 18 (CCL18), C-X-C motif chemokine ligand 14 (CXCL14), and C-C motif chemokine receptor 6 (CCR6) were upregulated genes involved in leukocyte subsets migration and differentiation in BIA-ALCL (50). The gene discussed is CCL18; the disease is anaplastic large cell lymphoma.
