## In brief

- An experimental drug eliminated about 75% of aggressive pancreatic tumours in mice, according to Medical Xpress.
- The drug also enhanced immune system memory in the treated mice.
- Many solid tumours, including pancreatic ones, are protected by a dense wall of scar-like tissue that keeps the immune system's cancer-killing T cells out.

## Why it matters

The scar-like barrier is a major reason immunotherapy drugs often fail against solid tumours, so a treatment that gets past it could matter for pancreatic cancer. The evidence so far comes from mice, not patients.
