CD40 and B-cell chronic lymphocytic leukemia: To explore BANK1 expression in activated and differentiated B cells, we examined three additional public datasets: human resting B cells vs. CD40 activated B cells [GSE54017 (16)], human resting B cells vs. Chronic Lymphocytic Leukemia (CLL) patient B cells [GSE22529 (17)], and human resting B cells vs. plasma cells [GSE6691 (18)] (Table 1).
