.... Vertebrates can be affected by elevated temperatures during development directly, and indirectly through maternal effects (e.g. exposure to prenatal glucocorticoid hormones). Past studies have examined how elevated temperatures and glucocorticoid exposure during development independently affect vertebrates...

...Paola M. Millanes; Lorenzo Pérez-Rodríguez; Juan G. Rubalcaba; Diego Gil; Blanca Jimeno ABSTRACT Glucocorticoid (GC) hormones have traditionally been interpreted as indicators of stress, but the extent to which they provide information on physiological state remains debated. GCs are metabolic...

How maternal psychosocial stress is signalled from the mother to the fetuses is unclear. Direct transfer of maternal glucocorticoids...

... with treatment. Indeed, there were no measurable, persistent effects of CORT treatment on oxidative damage markers in maternal tissues. Although it is known from past studies that glucocorticoid exposure can result in oxidative damage ( Costantini et al., 2011 ), there is also strong evidence that mice are able...

...David C. Ensminger; Daniel E. Crocker; Emily K. Lam; Kaitlin N. Allen; José Pablo Vázquez-Medina ABSTRACT The hypothalamic–pituitary–adrenal (HPA) axis controls the release of glucocorticoids, which regulate immune and inflammatory function by modulating cytokines, white blood cells and oxidative...

..., are these reaction norms themselves consistent over time, i.e. repeatable? Here, we quantified individual baseline glucocorticoid responses in house sparrows, Passer domesticus , to sequential manipulations of temperature, wind speed and food unpredictability that were repeated in discrete blocks of sampling under...

... to be mediated by glucocorticoids, but the impact of developmental glucocorticoid exposure on adult metabolism has rarely been studied and the results are equivocal. In this study, we examined the impact of developmental exposure to corticosterone (CORT, the main avian glucocorticoid hormone) on resting...

... infection. The neuroimmune response is inextricably linked to the action of the hypothalamic–pituitary–adrenal (HPA) axis. Cytokines released from neuroimmune cells, including microglia, activate the HPA axis, while glucocorticoids in turn regulate cytokine release from microglia. Because of the close links...

... and behavioural responses. Rapid elevation of glucocorticoid hormones in response to environmental stressors are widely implicated in adjusting physiological and behaviour processes that could influence irruptive movement capacity. However, there remains little direct evidence demonstrating that corticosterone...

We measured the energetic and nutritional costs across the entire larval period and metamorphosis in a larval amphibian exposed to exogenous glucocorticoid (GC) hormones – the primary hormone secreted by the HPA/I axis. We measured metabolic rates and dry mass across larval...

.... To fully understand how wild organisms are affected by stressors, it is crucial to understand the physiology that underlies an organism's response to a stressor. Prolonged levels of elevated glucocorticoids are associated with a state of chronic stress and decreased fitness. Exogenous glucocorticoid...

...Andréaz Dupoué; Frédéric Angelier; François Brischoux; Dale F. DeNardo; Colette Trouvé; Charline Parenteau; Olivier Lourdais ABSTRACT Circulating glucocorticoid (GC) levels may increase as a result of reproductive effort or in response to unpredictable events. However, GC secretion can vary...

Whereas short-term activation of this response helps animals cope with environmental stressors, chronic activation can result in negative effects...
