Abstract

Immunotherapy of tumors has become a research hotspot. Tumor-associated macrophages (TAMs) are the most abundant interstitial cells in a tumor’s microenvironment. As the concentration of the prepared nanoparticles increased, so their cytotoxicity of intensified. Under photothermal conditions, mAb-CD163/Au inhibited tumor invasion by killing M2 macrophages in vitro. After exposure to near-infrared (NIR) laser, mAb-CD163/Au inhibited tumor growth in vivo. The gold nanoparticles were modified to target M2 macrophages. Under NIR laser irradiation, mAb-CD163/Au achieved antitumor effects by killing M2 macrophages in vitro and in vivo.
