The research group led by Prof. Zeng Zhutian from the Division of Life Sciences and Medicine of the University of Science and Technology of China (USTC) revealed a new mechanism of immune surveillance by liver-resident macrophages called Kupffer cells (KCs) that prevent liver metastasis from occurring. They also developed a new method for in situ targeted expression and remodeling of KCs’ anti-tumor function, which successfully cleared tumors in various animal models with end-stage liver metastasis, thus providing a new approach to developing clinical immunotherapy for metastatic liver cancers.
