It should be noted that CXCR5 and/or CXCL13 have been shown to be associated with several non-AIDS-related B cell lymphomas, including extragastric lymphoma of mucosa-associated lymphoid tissue (MALT) and follicular lymphoma [13–17, 35]. The gene discussed is CXCL13; the disease is B-cell non-Hodgkin lymphoma.
