A team of 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 cells send signals that strengthen the tumor, but when they blocked this harmful communication in lab models, the cancer slowed its growth significantly.
Even more promising, the study suggests that an existing HIV medication could be repurposed to target this process and offer a new treatment option for patients who currently have few. The prognosis for glioblastoma is poor, with survival often measured in months.
"Glioblastoma isn't just a mass of cancer cells, it's an ecosystem," says Sheila Singh.
It's known that glioblastoma grows by forming a network of cells that communicate and support each other, and disrupting these connections can slow the cancer. This study dug deeper to uncover which brain cells are involved. The researchers discovered that a type of cell called an oligodendrocyte, normally responsible for protecting nerve fibers, can switch roles and actually support tumor growth.
These helper cells communicate with cancer cells through a specific signaling system, creating an environment that allows the tumor to thrive. When researchers blocked this communication in lab models, the cancer slowed down significantly, showing that this interaction is critical for glioblastoma's survival.
What makes this finding especially promising is that the signaling system involves a receptor called CCR5, which is already targeted by an existing HIV medicine called Maraviroc. This means a medication that's already approved and widely used could potentially be repurposed to treat glioblastoma.

It greatly slowed glioblastoma.
My neighbor,has 2 children who,had that gioblastoma.. terrible cancer!
Thanks for posting. A friend of mine I’ve known since High school, his brother in law went from diagnoses to death in only 2 weeks from glioblastoma, only 42. He came into work one day acting confused, couldn’t remember names and in only 2 weeks he was gone, totally shook me up. He went from being alive and normal to being a pile of dust in a tiny box on a fireplace mantle.
I really hope one day they can eradicate this horror, I think Ai will help a lot, but another side of me gets pessimistic when I see the extreme corruption going on today and barely anyone on the right willing to lift a finger to stop it.
Look how they treated Trump when he left office. Compare that to how they are treating these Somali bastard who ripped off $19 billion bucks. Anyone kicking in their door? Any of them being dragged out of their houses 4am in the morning like Roger Stone?
Glioblastoma killed my brother. After his initial surgery., the radiation and follow-up treatment really took its toll. I realize this article isnt saying it’s a cure, but if this medication could replace what he suffered through and extend lives, that would be wonderful for others.
