[QUOTE="DCUK NewsBot, post: 1533543, member: 106455"] German researchers have unlocked a previously unknown mechanism as to why people with diabetes have a higher risk of long-term complications. Scientists have identified inflammatory processes in the liver which increase cholesterol in people with diabetes. This, researchers believe, could promote the development of vascular diseases. They also discovered a molecule called GAbp (GA-binding protein) which provides a protective effect against vascular diseases, and could be important in preventing complications. "Our data suggest that the liver plays a key role in the development of common diabetic vascular diseases," said first author Dr. Katharina Niopek, researcher at the Institute for Diabetes and Cancer (IDC) at Helmholtz Zentrum Minchen. "GAbp appears to be a molecular regulator at the interface between inflammation, cholesterol homeostasis and atherosclerosis.
