Macrophage-Derived Neuropilin-2 Exhibits Novel Tumor-Promoting Functions

Tumor-associated macrophages (TAM) are causally associated with tumorigenesis as well as regulation of antitumor immune responses and have emerged as potential immunotherapeutic targets. Recent evidence suggests TAM phagocytose apoptotic tumor cells within the tumor microenvironment through efferocytosis in an immunologically silent manner, thus maintaining an immunosuppressed microenvironment. The signal transduction pathways coupling...
