Abstract:
Oncolytic viruses (OVs) can selectively kill tumor cells without affecting normal cells, as well as activate the innate and adaptive immune systems in patients. Thus, they have been considered as a promising measure for safe and effective cancer treatment. Recently, a few genetically engineered OVs have been developed to further improve the effect of tumor elimination by expressing specific immune regulatory factors and thus enhance the body's antitumor immunity. In addition, the combined therapies of OVs and other immunotherapies have been applied in clinical. Although there are many studies on this hot topic, a comprehensive review is missing on illustrating the mechanisms of tumor clearance by OVs and how to modify engineered OVs to further enhance their antitumor effects. In this study, we provided a review on the mechanisms of immune regulatory factors in OVs. In addition, we reviewed the combined therapies of OVs with other therapies including radiotherapy and CAR-T or TCR-T cell therapy. The review is useful in further generalize the usage of OV in cancer treatment.
Insights
Oncolytic viruses (OVs) offer a promising cancer treatment by selectively destroying tumor cells and stimulating the immune system. This review explores engineered OVs and their combination therapies to enhance antitumor immunity and effectiveness.
Area of Science:
- Oncology
- Virology
- Immunotherapy
Background:
- Oncolytic viruses (OVs) selectively target and eliminate cancer cells while activating anti-tumor immune responses.
- Engineered OVs express immune regulatory factors to amplify the body's natural defenses against tumors.
- Combined therapies involving OVs and other treatments like radiotherapy and cell therapies are increasingly explored.
Approach:
- This review synthesizes current research on the mechanisms of tumor destruction by OVs.
- It examines strategies for engineering OVs to enhance their efficacy.
- The review also covers the integration of OVs with other cancer treatment modalities.
Key Points:
- OVs provide a dual mechanism of action: direct oncolysis and immune system activation.
- Genetic modification of OVs can significantly boost their tumor-clearing capabilities.
- Combination strategies, including radiotherapy and CAR-T/TCR-T cell therapy, show potential for improved outcomes.
Conclusions:
- A comprehensive understanding of OV mechanisms and engineering is crucial for advancing cancer treatment.
- The review highlights the potential of OVs as a versatile platform for cancer immunotherapy.
- Further research and clinical application of OVs can broaden their use in oncology.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
