Exosomes decorated with anti-CD47 antibody for the co-delivery of cisplatin not only blocked the CD47-mediated “don’t eat me” signal and promoted macrophage-mediated phagocytosis of tumor cells, but also markedly enhanced the antitumor efficacy of cisplatin to overcome chemoresistance in non-small cell lung cancer (NSCLC) [13]. Here, CD47 is linked to neoplasm.
