"A nanoparticle and inhibitor trigger the immune system, outsmarting brain cancer: The approach, studied in mice, overcomes the blood brain barrier and breaks the shield tumors build against the immune response"

Scientists have fabricated a nanoparticle to deliver an inhibitor to brain tumor in mouse models, where the drug successfully turned on the immune system to eliminate the cancer. The process also triggered immune memory so that a reintroduced tumor was eliminated--a sign that this potential new approach could not only treat brain tumors but prevent or delay recurrences.
