Brain Tumors Hijack Sugar Metabolism to Fuel Growth, Suppress Immunity: Study

• A new study reveals brain tumors manipulate sugar metabolism, specifically fructose, to grow and suppress immune responses.
• Immune cells within glioblastoma, an aggressive brain tumor, use a unique fructose transporter (GLUT5) to metabolize sugar.
• Blocking fructose breakdown in these specialized immune cells could enhance immunotherapy effectiveness and patient outcomes.
• In mouse models, removing the GLUT5 transporter significantly inhibited tumor growth and boosted the immune system's anti-tumor response.
• Microglial fructose metabolism is identified as a key regulator of immune suppression in glioblastoma, offering a promising therapeutic target.
