ITGAX and neoplasm: Figure 1(b) showed that these ICBs are significantly smaller than those of live EL4 cells and are phagocyted by syngeneic BM-DCs. This was concluded because the CMTPX fluorescence from ICBs-EL4 was detected in live CD11c+ population (red peak) in a 28% approximately, in comparison with ICBs-EL4 without CMTPX (grey peak) (Figure 1(c)). The phagocytosis of antigenic tumor sources is a crucial stage to inducing an immune response in vivo. These structures yielded, along with the released extracellular vesicles, tumor antigen sources for our anticancer vaccine.
