Scientists uncover hidden cells fueling brain cancer—and a drug that could stop them

A team of Canadian scientists has uncovered a new way to slow the growth of glioblastoma, the most aggressive and currently incurable form of brain cancer—and identified an existing medication that could treat it.

Canadian Scientists Uncover Hidden Cells Fueling Brain Cancer -- and a Drug That Could Stop Them

Newswise — Hamilton, ON (January 21, 2026) – A team of Canadian scientists has uncovered a new way to slow the growth of glioblastoma, the most aggressive and currently incurable form of brain cancer – and identified an existing medication that could treat it. The research shows that certain brain cells – once thought to simply support healthy nerve function – actually help glioblastoma grow and spread. The researchers discovered that these cell…

Canadian Scientists Uncover Hidden Cells Fueling Brain Cancer — and a Drug That Could Stop Them

Researchers at McMaster University and The Hospital for Sick Children (SickKids) have identified a previously hidden population of brain cells that actively fuel glioblastoma growth — and, crucially, discovered that an existing HIV drug may be able to shut this process down.
