This was done on cells in a lab, not in people. It is a very early step.
This was only done on cells in the lab, not in people.
The short version
Tiny particles from the blood of people with glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary changed how tumor cells acted in lab dishes.
What was studied. Researchers collected tiny particles called extracellular vesicles from the blood of people with glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary and from healthy donors. They added those particles to glioblastoma cells and to normal brain support cells from rats and humans, all grown in the lab.
What they found. Particles from patients changed which marker proteins the tumor cells made. The effect was not the same in both tumor cell lines. Patient particles also raised the levels of growth signal receptors called EGFR and PDGFR in both tumor cell lines, and switched them on more in a model cell line. Particles from healthy donors also changed the cells, but in different ways.
What this means, and what it doesn't
What it could mean: It suggests these blood particles may carry signals that reach tumor cells. That may help scientists understand how glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary sends and spreads its signals. It gives researchers something new to study.
What it doesn't mean: This is not a treatment. It was all done on cells in dishes, not in people. No one was treated, and nothing here was shown to help a patient. It is not a promise of a cure. This is very early lab work, and it is a long way from anything a doctor can offer today.
