flag Tumors cause brain damage not just by invading tissue, but by pressing on neurons, triggering cell death and inflammation, according to Notre Dame researchers.

flag Chronic brain pressure from tumors like glioblastoma triggers neurons to activate self-destruction programs, leading to irreversible damage and neurological decline. flag Researchers at the University of Notre Dame used stem cell-derived brain models to show that sustained compression causes neuron and glial cell death, along with increased levels of stress and inflammation markers HIF-1 and AP-1—changes also seen in patients. flag These findings indicate mechanical forces contribute significantly to brain dysfunction beyond direct tumor invasion, offering new targets for therapies to protect neurons in brain tumors and other conditions involving physical stress on the brain.
