The one-two punch: TIM-3 blockade targets immune and tumor cells to knock out pediatric brain tumors

Diffuse midline gliomas (DMGs) pose treatment challenges due to their location within the brainstem and invasive nature. Although classical immune checkpoint inhibitors have demonstrated limited success in clinical trials, Ausejo-Mauleon et al. demonstrate TIM-3 is an effective DMG strategy, targeting both immune and tumor cells for dual therapeutic benefit.
