Connecting the dots between two molecules whose levels are decreased in depression and increased by current antidepressants could yield new therapies, researchers say. Serotonin is a neurotransmitter that enables brain cells to communicate and brain-derived neurotropic factor, or BDNF, is a brain-nourishing molecule that also aids connectivity. Popular antidepressants such as Prozac, developed to increase levels of serotonin, have recently been found to also increase BDNF levels, said Dr....

New Model Synapse Could Help With Disorders Such As Epilepsy And Anxiety
2012-08-08 09:42:42

A new way to study the role of a critical neurotransmitter in disorders such as epilepsy, anxiety, insomnia, depression, schizophrenia, and alcohol addiction has been developed by a group of scientists led by Gong Chen, an associate professor of biology at Penn State University. The new method involves molecularly engineering a model synapse -- a structure through which a nerve cell sends signals to another cell. This model synapse can precisely control a variety of receptors for the...

Michael Harper for redOrbit.com - Your Universe Online Cold feet are often equated to cowardice or second-thoughts when it comes to making a life-changing decision, such as going through with a marriage. Cold feet can also be more than just a joke people tell to be folksy. In fact, many people complain about their cold feet or the cold feet of a partner. Now, some physiologists have set their brains about figuring out why some people constantly have cold feet, saying a biological mechanism...

New research in the FASEB Journals demonstrates that blocking the delta opioid receptor in mice created resistance to weight gain and stimulated gene expression promoting non-shivering thermogenesis Imagine eating all of the sugar and fat that you want without gaining a pound. Thanks to new research published in The FASEB Journal (http://www.fasebj.org), the day may come when this is not too far from reality. That's because researchers from the United States and Europe have found that...

The research provides insights into programmed cell death and opens door to new approaches to cancer treatment Scientists at The Scripps Research Institute have simultaneously mapped two of the most important types of protein-modification in cells, revealing their extensive cooperation during an essential cellular process. Phosphorylation, the attachment of a phosphate group to a protein, and proteolysis, the cleavage of a protein, had almost always been studied independently. The new...

℠Traffic policeman´ protein directs crucial step in cell division A traffic policeman standing at a busy intersection directing the flow of vehicles may be a rare sight these days, but a similar scene appears to still frequently play out in our cells. A protein called Lem4 directs a crucial step of cell division by preventing the progress of one molecule while waving another through, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have...

Scientists have identified a new mechanism of bacterial pathogenesis. The results of the research project, partly funded by the Academy of Finland, have been published in the journal Proceedings of the National Academy of Sciences of the United States of America (PNAS). Bacteria that cause chronic infections have an amazing but yet poorly known ability to subvert immune response, live and produce offspring, enter and wake up from a dormant phase to cause, in some instances, deadly...

Protein binds to growth factor receptor, priming it for normal function; Likely tie to 4 cancers Once considered merely a passive link between proteins that matter, Grb2 - pronounced "grab2" - actually lives up to its nickname with its controlling grip on an important cell signaling pathway, scientists at The University of Texas MD Anderson Cancer Center report in the June 22 issue of Cell. "Grb2 is a switch that controls normal signaling through the fibroblast growth factor receptor...
