fused B16‐F10 CMs with RBC membranes to develop tumor antigen‐loaded nanoerythrosomes (nano‐Ag@erythrosome) as a tumor vaccine (Figure 4A).[35] Herein, the RBC membranes can be considered as a natural immune adjuvant, which utilizes their splenic APC targeting capacity to deliver the tumor antigens on the B16‐F10 CMs to APCs. Here, RENBP is linked to neoplasm.
