Furthermore, BAFF and its receptors are highly expressed in reactive lymphoid tissues and B-cell lymphomas, including diffuse large B-cell lymphoma (DLBCL), primary central nervous system lymphoma (PCNSL), mantle cell lymphoma (MCL), marginal zone B-cell lymphoma (MZBCL) and plasma cell myeloma (PCM). The gene discussed is TNFSF13B; the disease is marginal zone lymphoma.
