This was done in animals, not people. Most findings at this stage never become treatments.
This is early lab research, not yet tested in people.
The short version
Some brain cells send calming signals, and those signals seem to hold glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary growth back.
What was studied. Researchers looked at adult gliomas and the nearby brain cells that send calming signals. They turned those signals up and down, using both genes and drugs, to see what happened to the tumors.
What they found. The gliomas did receive calming signals from nearby brain cells. When the researchers made those signals stronger, tumors grew more slowly and survival was longer. When they blocked the signals, tumors grew faster. The calming signals also lowered calcium activity inside the tumor cells, and that activity drove tumor growth.
What this means, and what it doesn't
What it could mean: This points to a new idea about what controls glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary growth. Brain activity does not only feed tumors. Some brain signals may push back on them. If that holds up, drugs that boost calming signals might one day be tested as a treatment.
What it doesn't mean: This is early lab research. It does not mean a new treatment exists, and it is not a cure. No one has shown this works in people. It is a long way from anything a doctor can offer you. Do not change your care because of this study.
