The secret reason some cancer treatments stop working

Scientists have uncovered a hidden immune system "brake" that may help cancers avoid being destroyed. The molecule, called SLAMF6, weakens the body's cancer-fighting T cells and can leave them exhausted over time. Researchers developed antibodies that block this brake, allowing immune cells to stay stronger and attack tumors more effectively in mice.
