Abstract: Malignant tumor is considered as the uncontrolled growth and reproduction of cells.In order to avoid being eliminated,tumor cells form a variety of self-protection mechanisms,including resistance to apoptosis and immune escape by affecting the immune system.This makes tumor cells that have a strong ability to proliferate and have a high tendency of invasion and metastasis.Some patients,in the treatment,the effect is not ideal or after treatment,still appears recurrence and metastasis.Therefore,the research and development of new treatment methods are an urgent task.The discovery of oncolytic virus provides a new idea for the treatment of malignant tumors.With the deepening of the research on oncolytic virus,it is found that oncolytic virus can play an anti-tumor role through a variety of mechanisms.In addition to replicating in tumor cells and causing tumor cell lysis,it can also induce tumor cell apoptosis.Besides,oncolytic virus can activate immune cells,initiate anti-tumor immune response and change the immune microenvironment around tumor cells,which can play a long-term anti-tumor effect and inhibit uninfected tumor cells.Oncolytic virus plays a role in both cell apoptosis and anti-tumor immunity,which can effectively resist apoptosis and immune evasion of tumor cells,making a potential anti-tumor therapy.This article aims to introduce the research progress of oncolytic virus through inducing tumor cell apoptosis and activating immune system.
