Abstract
Subject headings
Close
- Polarization of tumor-associated macrophages (TAMs) to a proangiogenic/immune-suppressive (M2-like) phenotype and abnormal, hypoperfused vessels are hallmarks of malignancy, but their molecular basis and interrelationship remains enigmatic. We report that the host-produced histidine-rich glycoprotein (HRG) inhibits tumor growth and metastasis, while improving chemotherapy. By skewing TAM polarization away from the M2- to a tumor-inhibiting M1-like phenotype, HRG promotes antitumor immune responses and vessel normalization, effects known to decrease tumor growth and metastasis and to enhance chemotherapy. Skewing of TAM polarization by HAG relies substantially on downregulation of placental growth factor (PIGF). Besides unveiling an important role for TAM polarization in tumor vessel abnormalization, and its regulation by HRG/PIGF, these findings offer therapeutic opportunities for anticancer and antiangiogenic treatment.
