Of these, 18.46% (12/65) have a higher average distribution compared to all cytokines assessed in the case of MBLhi and 15.38% (10/65) for CLL; in addition, several of these proteins are common to both cases (MBLhi and CLL): IL-16, CXCL5, CXCL13, CCL22/MDC, CCL24/Eotaxin-2, CXCL12/SDF-1α, sIL-2R, sTWEAK, sCD30, sAPRIL, and sTRAIL.
