Targeting macrophage-derived SPP1 enhances CD8 T cell infiltration via ROS-DNA fragment/cGAS-STING/STAT1-mediated CXCL9/10 in tumor microenvironment
Background
Elevated levels of SPP1+ tumor-associated macrophages (TAMs) are associated with reduced CD8+ T cell infiltration and poorer prognosis in cancer patients, but direct evidence demonstrating a causal role for SPP1+ TAMs in excluding CD8+ T ce…
