Ginseng-Derived Nanoparticles Reprogram Macrophages to Regulate Arginase-1 Release for Ameliorating T Cell Exhaustion in Tumor Microenvironment

By regulating the mTOR-T-bet axis, ginseng-derived nanoparticles reprogramed macrophages to regulate arginase-1 release, which further ameliorated T cell exhaustion in tumor microenvironment.
