Unusual expression of FCRL1 and BAFF was stated in diffuse large B cell lymphoma (DLBCL) cell lines and Burkitt lymphoma (BL) [12,13,17] as well as follicular lymphoma (FL), mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), hairy cell lymphoma (HCL), and multiple myeloma (MM) [12,13]. This evidence concerns the gene TNFSF13B and follicular lymphoma.
