Mapping the Uncharted Territories of Human Brain Malignancies

Abstract

Despite its success in multiple tumor types, immunotherapy remains poorly efficacious in brain malignancies. In this issue of Cell, Friebel et al. and Klemm et al. provide in-depth insights into the versatile nuances of immune cells in primary and metastatic brain tumors, granting the field with a rich framework to explore novel therapeutic avenues.
