Immune cells called mast cells slowed brain tumor growth in lab and animal tests
Original title: Mast cells suppress glioblastoma progression via endoplasmic reticulum stress.

- Review
- Tested in people
This was done in animals, not people. Most findings at this stage never become treatments.
This was only tested on cells in a dish and in animals.
The short version
Scientists found that switching on one kind of immune cell slowed glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary in the lab and in animals.
What was studied. Researchers looked at mast cells, a type of immune cell found inside glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary tumors. They used a large tumor database, tumor samples from patients, and tests on tumor cells and on animals.
What they found. Most mast cells in the tumors were resting, not active. When the team switched the mast cells on with a lab chemical, the tumor cells grew less and more of them died. Tumors also grew more slowly in animals. The mast cells seemed to work by putting stress on the tumor cells from the inside.
What this means, and what it doesn't
What it could mean: Someday, doctors might find a way to switch on the body's own mast cells to fight glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary. This study helps scientists understand how that could work.
What it doesn't mean: This is not a new treatment. The work was done only on cells in a dish and in animals, not in people. It is far from everyday care, and it is not a cure. Much more research is needed before it could be tested in patients.
