How acute is the acute stress response? Baseline corticosterone and corticosteroid-binding globulin levels change 24 h after an acute stressor in Japanese quail

摘要: Changes in plasma corticosteroid-binding globulin (CBG) capacity can alter free concentration and tissue availability of glucocorticoids (GC) hence the organismal response to stress. However, CBG change stress has not been extensively studied. While it is clear that chronic causes decline some species acute stressors reduce during 30–60 min stressor, more long-term changes following an stressor received less attention. Here we investigated corticosterone (CORT: primary GC birds) levels 24 h after a unique study system: Japanese quail divergently selected for CORT reactivity Using this model, examined interaction with determine if shows delayed varies by genetic background. We found lowered capacity, elevated total all three groups. These results demonstrate first time avian exposure affect later.
