ITGAM and B-cell non-Hodgkin lymphoma: Similar results were obtained with CB-derived primary macrophages ectopically expressing SIRP-ß2, with a significant increase in CD11b expression (Figure 2J) and a significant increase in phagocytosis of various B cell lymphoma cell lines (p<0.05 for Daudi, U2932; p<0.01 for Ramos; p<0.001 for SUDHL-6) compared to EV-transduced macrophages (Figure 2K).
