Inflammatory Protein Linked to Lung Cancer

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.
