Genetic selection for low glucocorticoid responsiveness recapitulates PTSD-related phenotypes: a behavioral, neuroimaging and sleep-physiology study

Silvia Monari

Humans show inter-individual differences in vulnerability to develop post-traumatic stress disorder (PTSD) following exposure to trauma. Several critical biobehavioral features have been consistently described in PTSD patients, including blunted cortisol l ...

Programming effects of peripubertal stress on spatial learning

Maria del Carmen Sandi Perez, Stamatina Tzanoulinou

Exposure to adversity during early life can have profound influences on brain function and behavior later in life. The peripubertal period is emerging as an important time-window of susceptibility to stress, with substantial evidence documenting long-term ...

Increased brain glucocorticoid actions following social defeat in rats facilitates the long-term establishment of social subordination

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Meltem Weger

Social rank is frequently established through aggressive encounters between new conspecifics. Despite increasing evidence suggesting that social rank is critical for the well-being of both humans and animals, knowledge about the factors influencing social ...

No Scope for Social Modulation of Steroid Levels in a Year-Round Territorial Damselfish

Both latitude and mating system have been proposed to shape relationships between steroid hormone levels and social behavior. Recently it has been postulated that species with long lasting non-seasonal territorial behavior have low androgen responsiveness. ...

Increased corticosterone in peripubertal rats leads to long-lasting alterations in social exploration and aggression

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Stamatina Tzanoulinou, Vandana Veenit

Stress during childhood and adolescence enhances the risk of psychopathology later in life. We have previously shown that subjecting male rats to stress during the peripubertal period induces long-lasting effects on emotion and social behaviors. As cortico ...

Role of the HPA axis in the long-term programming of social behaviors by peripuberty stress : behavioral, pharmacological and molecular approaches

Vandana Veenit

Stress during childhood and adolescence enhances the risk of psychopathology later in life. In fact, exposure to stress during this period is known to predispose individuals to the development of psychopathologies such as depression and anxiety disorders l ...

Evidence for biological roots in the transgenerational transmission of intimate partner violence

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Guillaume Poirier, Vandana Veenit, Basira Salehi

Intimate partner violence is a ubiquitous and devastating phenomenon for which effective interventions and a clear etiological understanding are still lacking. A major risk factor for violence perpetration is childhood exposure to violence, prompting the p ...

Cholesterol Catabolism by Mycobacterium tuberculosis Requires Transcriptional and Metabolic Adaptations

John McKinney

To understand the adaptation of Mycobacterium tuberculosis to the intracellular environment, we used comprehensive metabolite profiling to identify the biochemical pathways utilized during growth on cholesterol, a critical carbon source during chronic infe ...

Neurobiological Mechanisms Involved in the Establishment and Maintenance of Dominance Hierarchies and its Modulation by Stress in Rats

Maria del Carmen Sandi Perez, Marjan Timmer

Stress can have a strong and long lasting effect on the establishment and maintenance of dominance hierarchies in rats. When two rats of a pair have not been stressed (non-stressed pair) before a first social encounter, they establish a dominance hierarchy ...

Stimulation-induced increases of astrocytic oxidative metabolism in rats and humans investigated with 1-11C-acetate

Pierre Magistretti

The purpose of this study was to investigate astrocytic oxidative metabolism using 1-(11)C-acetate. 1-(11)C-acetate kinetics were evaluated in the rat somatosensory cortex using a beta-scintillator during different manipulations (test-retest, infraorbital ...
