Delayed effects of corticosterone on slow after-hyperpolarization potentials in mouse hippocampal versus prefrontal cortical pyramidal neurons. [PDF]

open access: yesPLoS ONE, 2014
The rodent stress hormone corticosterone changes neuronal activity in a slow and persistent manner through transcriptional regulation. In the rat dorsal hippocampus, corticosterone enhances the amplitude of calcium-dependent potassium currents that cause

Grading Distress of Different Animal Models for Gastrointestinal Diseases Based on Plasma Corticosterone Kinetics

open access: yesAnimals, 2019
Comparative studies for evaluating distress in established animal models are still rare. However, this issue is becoming more important as a consequence of worldwide appreciation of animal welfare.

Corticosterone Production during Repeated Social Defeat Causes Monocyte Mobilization from the Bone Marrow, Glucocorticoid Resistance, and Neurovascular Adhesion Molecule Expression

open access: yesJournal of Neuroscience, 2018
Repeated social defeat (RSD) stress promotes the release of bone marrow-derived monocytes into circulation that are recruited to the brain, where they augment neuroinflammation and cause prolonged anxiety-like behavior. Physiological stress activates the

Corticosterone selectively decreases humoral immunity in female eiders during incubation [PDF]

open access: yesJ. Exp. Biol. 209 (2006) 4957-4965, 2007
Immunity is hypothesized to share limited resources with other physiological functions and this may partly account for the fitness costs of reproduction. Previous studies have shown that the acquired immunity of female common eider ducks (Somateria mollissima) is suppressed during their incubation, during which they entirely fast.

Towards the convergent therapeutic potential of G protein‐coupled receptors in autism spectrum disorders

open access: yesBritish Journal of Pharmacology, EarlyView., 2023
Abstract Autism spectrum disorders (ASDs) are diagnosed in 1/100 children worldwide, based on two core symptoms: deficits in social interaction and communication, and stereotyped behaviours. G protein‐coupled receptors (GPCRs) are the largest family of cell‐surface receptors that transduce extracellular signals to convergent intracellular signalling ...

Permissive Influence of Stress in the Expression of a U-Shaped Relationship between Serum Corticosterone Levels and Spatial Memory Errors in Rats

open access: yesDose-Response, 2006
The relationship between glucocorticoids (GCs) and memory is complex, in that memory impairments can occur in response to manipulations that either increase or decrease GC levels.

Corticosterone Can Be an Essential Stress Index in Channel Catfish (Ictalurus punctatus)

open access: yesFrontiers in Marine Science, 2021
Although cortisol is considered the main glucocorticoid involved in regulating stress in fish by elevating the serum glucose, the presence of serum corticosterone and whether its level can be used as an indicator for fish stress activation and reflect ...

Innate immunity, assessed by plasma NO measurements, is not suppressed during the incubation fast in eiders [PDF]

open access: yesDev. Comp. Immunol. (19/12/2006) 29 pages, 2007
Immunity is hypothesized to share limited resources with other physiological functions and may mediate life history trade-offs, for example between reproduction and survival. However, vertebrate immune defense is a complex system that consists of three components.

Pre- and postnatal effects of experimentally manipulated maternal corticosterone on growth, stress reactivity and survival of nestling house wrens.

open access: yesFunctional Ecology, 2018
Corticosterone plays a central role in maintaining homeostasis, promoting energy acquisition, and regulating the stress response in birds. Exposure to elevated levels of corticosterone during development can profoundly alter offspring behaviour and ...

The Comparison of the Effects of Acute Swimming Stress on Plasma Corticosterone and Leptin Concentration in Male and Female Rats [PDF]

open access: yesActa Medica Iranica, 2011
The aim of this study was to investigate the effect of acute swimming stress on plasma corticosterone and leptin levels in female and male rats. Thirty- seven adult male (n=20) and female (n=20) Sprague Dawley rats (200-250 g weight) were used.
