Clinical activity of CD20 immunotargeting in metastatic melanoma patients. PET-CT scans from two different patients obtained pre- vs. post-anti-CD20 antibody therapy. a, b Note complete disappearance of a metabolically active metastatic site (white arrow); c, d mixed response with almost complete disappearance of one metabolically active metastatic site (white arrow in d) and simultaneous increase in size and metabolic activity of the other (red arrow in d). e Representative combined PAX5 (nuclear; purple)/CD20 (membrane; yellow) immunofluoresence staining of patient-matched melanoma samples before and after therapy with anti-CD20 antibody (overviews (top rows; scale bars: 100 μm) and corresponding close ups (bottom rows; scale bars: 10 μm)). Note depletion of TAB cells in post-therapy tumors. CSPG staining of melanoma cells (green) and nuclear DAPI staining (blue). Right panel: double positive PAX5 (nuclear)/CD20 (membrane) immunofluoresent TAB cells
