Abstract:
The immune system is a crucial regulator of tumor biology with the capacity to support or inhibit cancer development, growth, invasion and metastasis. Emerging evidence show that reactive oxygen species (ROS) are not only mediators of oxidative stress but also players of immune regulation in tumor development. This review intends to discuss the mechanism by which ROS can affect the anti-tumor immune response, with particular emphasis on their role on cancer antigenicity, immunogenicity and shaping of the tumor immune microenvironment. Given the complex role that ROS play in the dynamics of cancer-immune cell interaction, further investigation is needed for the development of effective strategies combining ROS manipulation and immunotherapies for cancer treatment.
Insights
Reactive oxygen species (ROS) significantly influence the immune system's fight against tumors by affecting cancer antigenicity and the tumor microenvironment. Understanding ROS's complex role is key for developing new cancer immunotherapies.
Area of Science:
- Immunology
- Oncology
- Biochemistry
Background:
- The immune system critically influences tumor progression, either promoting or suppressing cancer.
- Reactive oxygen species (ROS) are increasingly recognized for their dual role in oxidative stress and immune regulation during tumor development.
Purpose of the Study:
- To review the mechanisms by which ROS impact anti-tumor immune responses.
- To emphasize the role of ROS in cancer antigenicity, immunogenicity, and the tumor immune microenvironment.
Main Methods:
- Literature review of existing research on ROS and the immune system in cancer.
- Analysis of the molecular and cellular pathways affected by ROS in the tumor microenvironment.
Main Results:
- ROS modulate cancer antigen presentation and immune cell function within the tumor microenvironment.
- ROS influence the balance between pro-tumor and anti-tumor immune responses.
Conclusions:
- ROS play a complex, multifaceted role in cancer immunity.
- Targeting ROS in conjunction with immunotherapies may offer novel strategies for cancer treatment.

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...
