Targeting TREM2+ and TIMD4+ Macrophages Reprograms the Tumor Microenvironment and Enhances PD-1 Blockade Efficacy in Intrahepatic Cholangiocarcinoma
Background: Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver cancer. Macrophages are crucial components of the tumor microenvironment (TME). Triggering receptor expressed on myeloid cells 2-positive (TREM2+) macrophages have recently emerged as potent pro-tumor progress players in several c...
