The disrupted metabolism of sugar, fat and calcium is part of the process that causes the death of neurons in Alzheimer's disease. Researchers from Karolinska Institutet in Sweden have now shown, for the first time, how important parts of the nerve cell that are involved in the cell's energy metabolism operate in the early stages of the disease. These somewhat surprising results shed new light on how neuronal metabolism relates to the development of the disease. http://medicalxpress.com/news/2013-04-early-stage-alzheimer-disease.html Alzheimer's disease & dementia Mon, 22 Apr 2013 15:00:13 EST news285854606 Researchers at the University of California, San Diego School of Medicine report that tumor cells use stress signals to subvert responding immune cells, exploiting them to actually boost conditions beneficial to cancer growth. http://medicalxpress.com/news/2012-12-cancer-cells-co-opt-immune-response.html Cancer Tue, 18 Dec 2012 17:00:02 EST news275072249 (Medical Xpress)—Drugs for psychiatric disorders such as depression and schizophrenia often require weeks to take full effect. "What takes so long?" has formed one of psychiatry's most stubborn mysteries. Now a fresh look at previous research on quite a different drug—nicotine—is providing answers. The new ideas may point the way toward new generations of psychiatric drugs that work faster and better. http://medicalxpress.com/news/2012-11-approach-common-psychiactric-treatments.html Psychology & Psychiatry Wed, 21 Nov 2012 07:50:13 EST news272706592 Inflammation and cell stress play important roles in the death of insulin-secreting cells and are major factors in diabetes. Cell stress also plays a role in Wolfram syndrome, a rare, genetic disorder that afflicts children with many symptoms, including juvenile-onset diabetes. http://medicalxpress.com/news/2012-08-treatment-diabetes-wolfram-syndrome.html Inflammatory disorders Tue, 07 Aug 2012 12:44:11 EST news263562230 Scientists have discovered a new function for a protein that protects cells during injury and could eventually translate into treatment for conditions ranging from cardiovascular disease to Alzheimer's. http://medicalxpress.com/news/2012-06-newly-protein-function-cells-injury.html Medical research Thu, 07 Jun 2012 12:00:01 EST news258289123 In type 1 diabetes (T1D), pancreatic beta cells die from a misguided autoimmune attack, but how and why that happens is still unclear. Now, JDRF-funded scientists from the Indiana University School of Medicine have found that a specific type of cellular stress takes place in pancreatic beta cells before the onset of T1D, and that this stress response in the beta cell may in fact help ignite the autoimmune attack. These findings shed an entirely new light into the mystery behind how changes in the beta cell may play a role in the earliest stages of T1D, and adds a new perspective to our understanding how T1D progresses, and how to prevent and treat the disease. http://medicalxpress.com/news/2012-03-beta-cell-stress-trigger-diabetes.html Diabetes Thu, 22 Mar 2012 16:39:04 EST news251653138 The discovery of a gene that causes a form of hereditary spastic paraplegia (HSP) may provide scientists with an important insight into what causes axons, the stems of our nerve cells, to degenerate in conditions such as multiple sclerosis. http://medicalxpress.com/news/2012-01-spasticity-gene-clues-nerve-cell.html Genetics Mon, 09 Jan 2012 12:47:13 EST news245335624
