This was done on cells in a lab, not in people. It is a very early step.
This was only done with cells in lab dishes.
The short version
In lab dishes, treated immune cells killed glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary cells.
What was studied. Researchers built tiny fat bubbles to carry mRNA into immune cells. The mRNA told T cells to make a receptor aimed at CD276, also called B7 H3, a marker found on glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary cells.
What they found. The fat bubbles held the mRNA well and got it into cells. Different cell types made different amounts of the new protein, including K562, NK, NK92, and T cells. T cells given the CD276 instructions killed LN229 glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary cells that carried CD276. All of this happened in lab dishes.
What this means, and what it doesn't
What it could mean: This points to a simpler way to make CAR T cells without using a virus. The fat bubble method may be easier to adjust and produce. For now it is a lab method, not care a doctor can offer.
What it doesn't mean: This is not a cure, and it is not a treatment. The work was done only with cells in dishes. No people and no animals were treated in this study. The authors say the next step is testing in animals. Much more testing would be needed before anything like this could reach patients.
