Summary:
- The article reports on a new study that has identified a previously unknown mechanism by which cancer cells evade the immune system.
- The researchers discovered that cancer cells can hijack a protein called TIGIT, which normally acts as a checkpoint to prevent the immune system from attacking healthy cells, and use it to suppress the activity of T cells that would otherwise target the cancer.
- The findings suggest that targeting the TIGIT pathway could be a promising new approach for developing more effective cancer immunotherapies.
