While inflammation is part of the normal immune response, chronic inflammation is linked to many diseases, including cancer. Now, new research shows that white blood cells near non-small cell lung cancers have high levels of a protein that amplifies inflammation. Called TREM-1, this protein is not found in white blood cells from normal lung tissue. These findings were presented at the 2013 meeting of the American College of Chest Physicians. TREM-1 has also been linked to liver cancer and some breast cancers; researchers suspect that this protein helps tumor cells invade tissue and spread to other parts of the body. In addition, recent research shows that TREM-1 can be inhibited with prostaglandins, which are antiinflammatory biomolecules that promote healing.
