Scientists use advanced imaging to track brain tumor ‘turncoats’

Related video Glioblastomas, the deadliest type of brain tumor in adults, attract “turncoats.” These are macrophages, a type of immune cell, which promote tumor progression and mask tumors from the immune system’s scrutiny. To better understand the cells that brain tumors recruit, scientists led by Dolores Hambardzumyan, PhD, developed advanced imaging techniques to visualize macrophages […]
