摘要

Background: Activation of the immune system to fight cancer is a major goal in immunology and oncology. Although cancer treatment using oncolytic viruses shows promising results, virus mediated oncolysis induces a weak anti-tumor immune response. Upon application of viruses, immune responses against the virus play a significant role in limiting tumor virotherapy. Although suppression of host immunity increases the efficacy of virotherapy against the tumor, but inhibits anti-tumor immune responses. Induction of viral specific tolerance before viral replication may cause the virus to efficiently replicate in tumor cells without affecting the immune responses against tumor antigens. Investigation of the combined strategy of virotherapy and immunotherapy using irradiated tumor cells along with IL-2 and interferon-alpha in virus specific tolerant mice was the goal of this study.
