Blocking a female-only GABA signal that helps glioblastoma evade immunity may boost survival

Researchers have identified a critical biological difference in how glioblastoma develops in male and female laboratory models, pinpointing an immune pathway that fuels tumor growth only in females.

The study shows that the neurotransmitter GABA boosts the cancer-protecting activity of immune cells in female models—but not male models—and that blocking that signal improved outcomes.

The findings could one day lead to new drug targets and therapeutics specifically for women.
