🦠 Modified Herpes Virus Fights Brain Cancer

Researchers at Dana-Farber and Mass General Brigham found that a modified herpes virus can help the immune system attack glioblastoma. One injection of this "oncolytic" virus recruits T cells deep into these deadly tumors, overcoming the biological "shield" that usually blocks standard immunotherapy.

The study shows this approach extends survival by making aggressive brain cancers vulnerable to the body's defenses. This discovery offers a new way to treat tumors that were previously considered unreachable by the immune system.
