CD1d expression in normal and clonal B-cells. (A) CD1d expression in a B-CLL (i) and a MCL (ii) patient. Normal B-cells are shown in orange and CD5+ neoplastic lymphocytes in green. (B) Stronger expression of CD1d in HCL (filled histogram in i, green color in ii) compared to SLVL (open histogram, i) and normal B cells (orange color, ii).
