Blood Protein Might Signal Death Risk in Elderly, Uppsala Universitet Study  
8/31/2011 7:46:09 AM

Swedish scientists have identified a protein circulating in the blood which seems to be a harbinger of an increased risk of death among elderly people. The protein, cathepsin S, is strongly tied to the inflammatory processes that are central to killers such as cancer and heart disease. The authors of the new study, published online Aug. 30 in the Journal of the American Medical Association and simultaneously being presented at the European Society of Cardiology Congress in Paris, suggest that the protein might be a target for drugs, some of which are already being tested in trials.
