In MALT lymphoma cells, the B-cell attracting chemokine 1 (BCA-1) and its receptor C-X-C motif chemokine receptor 5 (CXCR5) are augmented, which regulate B-cells and promote the production of the inflammation-causing interleukin-8 (IL-8) (140). The gene discussed is CXCR5; the disease is MALT lymphoma.
