A study spearheaded by a Stanford University School of Medicine scientist has tracked the trajectories of key immune cells in response to short-term stress and traced, in great detail, how hormones triggered by such stress enhance immune readiness. The study, conducted in rats, adds weight to evidence that immune responsiveness is heightened, rather than suppressed as many believe, by the so-called "fight-or-flight" response. The study's findings provide a thorough overview of how a triad...

Authors explore the role of the SRY gene in male fight-or-flight response The pulse quickens, the heart pounds and adrenalin courses through the veins, but in stressful situations is our reaction controlled by our genes, and does it differ between the sexes? Australian scientists, writing in BioEssays, believe the SRY gene, which directs male development, may promote aggression and other traditionally male behavioral traits resulting in the fight-or-flight reaction to stress. Research...

Findings indicate bi-directional relationships between alcohol and stress. Results will be published in the October 2011 issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View. "Anecdotal...

All those salty snacks available at the local tavern might be doing more than increasing your thirst: They could also play a role in suppressing social anxiety. New research from the University of Cincinnati (UC) shows that elevated levels of sodium blunt the body's natural responses to stress by inhibiting stress hormones that would otherwise be activated in stressful situations. These hormones are located along the hypothalamic-pituitary-adrenal (HPA) axis, which controls reactions to...

New research shows that when some fence lizards are attacked by fire ants they "stress out"-- a response that actually helps the species to survive by heightening the animal's awareness of imminent danger. Tracy Langkilde, assistant professor of biology at Penn State University, found that lizards living in areas of the southeastern United States, where large numbers of fire ants also live, have elevated levels of stress hormones, called glucocorticoids. The stress-hormone study comes on the...
