Researchers studying mice are getting closer to understanding how stress affects mood and motivation for drugs. According to the researchers, blocking the stress cascade in brain cells may help reduce the effects of stress, which can include anxiety, depression and the pursuit of addictive drugs. A research team from St. Louis and Seattle reports in the Aug. 11 issue of the journal Neuron that in mice exposed to stress, a protein called p38ÃŽ± mitogen-activated protein...

Stressful experiences increase addictive drug consumption and can precipitate bouts of anxiety or depression in vulnerable people. Although the mechanisms linking stress and human behaviors are not well understood, animal models of some aspects of these behaviors have been developed and have been used to define some of the molecular events that may be responsible for stress vulnerability in people. The goal of these studies is to identify potential new therapeutics that may enhance stress...

Effect is on pathways that regulate serotonin and can lead to low mood Stress-evoked changes in circuits that regulate serotonin in certain parts of the brain can precipitate a low mood and a relapse in cocaine-seeking, based on mouse studies published online this week in the Proceedings of the National Academy of Sciences. "The impetus for this research was our interest in how stress alters the brain's cell receptors and protein signals in ways that lead to mood changes, depression, anxiety,...
