Central vasopressin V1A receptor blockade alters patterns of cellular activation and prevents glucocorticoid habituation to repeated restraint stress exposure.
Our previous experiments implicated a role for the arginine vasopressin (AVP) V1A receptor subtype in mediating the normal decline (habituation) of hypothalamic-pituitary-adrenal (HPA) axis responses to repeated restraint exposure. To explore pathways mediating the endogenous effects of central AVP on stress HPA axis habituation, here we compared cellular (Fos) and hormone responses in male rat...
متن کاملProbiotic supplementation improves the cognitive function and the anxiety-like behaviors in the stressed rats
Objective(s): Prenatal stresses increase incidence of neurodevelopmental disorders and influence cognitive abilities. Glucocorticoids are released in stress condition as endpoint activation of hypothalamus-pituitary-adrenal (HPA) axis. Evidence indicates a cross-talk between gut microbiota and brain function. This study assesses the effect of probiotic supplementation ...
متن کاملThe Role of the Endocannabinoids in Suppression of the Hypothalamic- pituitary-adrenal Axis Activity by Doxepin
Objective(s) The mechanism(s) by which antidepressants regulate the hypothalamic-pituitary-adrenal (HPA) axis remain elusive. The endocannabinoid system (eCBs) which exhibits antidepressant potential, appears to regulate the HPA axis activity. Therefore, we aimed to investigate the role of the eCBs in the action of doxepin including its effect on the HPA axis. Materials and Methods Male Wist...
متن کاملSpinal and supraspinal analgesic effects of Nimodipine : The role of Hypothalamo-Pituitary-Adrenal(HPA) axis .
Nimodipine, an L-type calcium channel blocker, can induce analgesia. However, it is not clear that this analgesic effect is at the level of spinal or supraspinal pain pathway. In addition, it has been reported that the analgesic effect of nifedipine, another L-type calcium channel blocker is related to the HPA axis, but there is no report indicating the role of this axis in the analgesic eff...
متن کاملPost-stress rumination predicts HPA axis responses to repeated acute stress.
Failure of the hypothalamus-pituitary-adrenal (HPA) axis to habituate to repeated stress exposure is related with adverse health outcomes, but our knowledge of predictors of non-habituation is limited. Rumination, defined as repetitive and unwanted past-centered negative thinking, is related with exaggerated HPA axis stress responses and poor health outcomes. The aim of this study was to test w...
