Current status and research progress of oncolytic virus

Area of Science:

• Oncolytic virology
• Cancer immunotherapy
• Tumor microenvironment modulation

Background:

• Oncolytic viruses (OVs) are viruses that selectively infect and destroy tumor cells.
• OVs represent a promising avenue in cancer immunotherapy, activating anti-tumor immune responses.
• They can also regulate the tumor microenvironment and enhance other cancer therapies.

Purpose of the Study:

• To review the latest research on oncolytic viruses.
• To discuss their characteristics and antitumor mechanisms.
• To summarize the challenges and future prospects of OV applications in cancer treatment.

Main Methods:

• Literature review of recent studies on oncolytic viruses.
• Analysis of OV characteristics and mechanisms of action.
• Synthesis of current research status, challenges, and future directions.

Main Results:

• OVs exhibit dual mechanisms: direct tumor cell lysis and indirect antitumor effects.
• OVs activate antitumor immunity and modulate the tumor microenvironment.
• Current research highlights OV potential but also identifies significant challenges.

Conclusions:

• Oncolytic viruses offer a novel immunotherapy approach with direct and indirect antitumor effects.
• Further research is needed to overcome challenges for successful clinical application.
• OVs hold significant promise for future cancer treatment strategies.
