Abstract:
Allogeneic liver transplants tolerize the immune system, preventing organ rejection from the same donor. A recent article by Yu et al. shows that liver metastases can likewise prevent tumor rejection in immunotherapy-treated murine and human hosts. Furthermore, radiation can reprogram the liver microenvironment to restore systemic tumor rejection.
