This research links two major treatment challenges in childhood acute lymphoblastic leukemia through ferroptosis, a lipid oxidation process regulated by selenium. By targeting selenium uptake in the brain and after chemotherapy, the work identifies potential new therapeutic strategies to reduce cancer cell survival and improve long-term treatment outcomes.

Pediatric brain tumors are the leading cause of cancer-related death in children, and current treatments are often insufficient. This research explores harnessing the immune system, particularly macrophages, to fight these tumors. Using advanced imaging and engineered immune cells, the work aims to improve tumor clearance and develop new therapeutic strategies.
