  "textContent": "Northwestern Medicine scientists have discovered that specialized immune cells within the glioblastoma tumor metabolize fructose to suppress immune responses and promote tumor growth, reports a study published in the Proceedings of the National Academy of Sciences. The study, the first to identify this sugar pathway as a driver of immune suppression in brain tumors, suggests that blocking fructose metabolism in the specialized cells may improve immunotherapy response and patient outcomes.",
