CD19 and melanoma: As shown in Figures 2B,C, examples of relationships included: increases in the population of cells in melanoma patients prior to treatment with either decreased RFS (B cells without NO; node 86 = CD19+CD25−/loDAF-FM−/lo or+/lo; Figure 2B) or increased RFS (Effector T cells; node 155 = CD3+CD8+CD25−/loDAF-FM+), respectively (Figure 2C).
