Immune system may help treat brain tumors.

In Brain Cancer, Brain Science by Brainy Days Ahead

Immune checkpoint inhibitors are a new group of cancer treatments that work by boosting the patient’s immune response to the tumor. The immune system operates differently in the brain in comparison to other organs. This study is designed to find out whether the immune system is activated and working in brain tumors,  providing the foundation for immune checkpoint inhibitors to work. The research shows that brain metastases have dense concentrations of tumor infiltrating lymphocytes, providing an immunoactive environment.
