Researchers at the Institute for Research in Biomedicine (IRB Barcelona, Spain)) have discovered that deficiency of a single protein, Mitofusin 2, in muscle and hepatic cells of mice is sufficient to cause tissues to become insensitive to insulin, thus producing an increase in blood glucose concentrations. These are the two most common conditions prior to development of diabetes type 2. Published in this week's issue of Proceedings of the National Academy of Sciences (PNAS), the study validates Mitofusin 2 as a possible target for the treatment of diabetes type 2. http://medicalxpress.com/news/2012-03-validate-potential-protein-treatment-diabetes.html Diabetes Fri, 23 Mar 2012 10:25:11 EST news251717103 An emerging body of research suggests that Alzheimer's disease may be linked to insulin resistance, constituting a third type of diabetes. This model is based on several observations including an increased risk of developing Alzheimer's disease for diabetic patients, and reduced insulin levels in the brain tissue of Alzheimer's disease patients. http://medicalxpress.com/news/2012-03-evidence-links-alzheimer-disease-diabetes.html Alzheimer's disease & dementia Tue, 20 Mar 2012 12:33:01 EST news251465563
