Kind: research · Impact: medium

## In brief

- Scientists report that tumours release natural antioxidants that shut down immune cells responsible for destroying cancer.
- Blocking this mechanism in mice restored immune activity and improved immunotherapy, according to the ScienceDaily report.
- The findings come from a mouse study; the source does not report human trial results.

## Why it matters

The work points to a possible way to make cancer immunotherapy more effective by targeting how tumours suppress immune cells, though results so far are from mice.
