Cancer uses antioxidants to disarm the immune system, scientists discover
The 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.
Who’s affected
- cancer researchers and immunologists
- clinicians working with immunotherapy
- patients with cancer who may receive immunotherapy
