A new study reveals the mechanism by which aggressive triple-negative breast cancer (TNBC) disables the body’s immune response. Researchers found that these cancer cells release a specific protein that directly suppresses the activity of T-cells, the immune system’s primary fighters against tumors. This process allows the cancer to evade detection and grow unchecked. The discovery identifies a potential target for new therapies that could block this protein and reactivate the immune system to attack the cancer. Further research is needed to translate these findings into clinical treatments. For the full details, read the complete article at: https://www.sciencedaily.com/releases/2026/04/260411022031.htm
