Scientists discover rogue messengers that hinder body’s immune response to cancer

Researchers from Trinity College Dublin have made a discovery around treatment-resistant breast cancer that may turn the phrase, ‘don’t shoot the messenger’, on its head. The scientists have found that cell to cell messengers released by cancer cells which are not responding to treatment, can negatively affect the body’s immune system response against the cancer. They have also discovered a possible way for doctors to identify those patients most at risk of treatment resistance.
