Implication of individual differences in glucocorticoid responsiveness to stress in the development of psychopathology-like behaviour and underlying neurobiology

Sophie Elizabeth Walker

The period around puberty is a critical window in development. It is a time of neuroendocrine and neuroanatomical lability, rendering individuals highly sensitive to stress. Indeed, early adversity increases risk for psychopathology. The mechanisms via whi ...

New insights into ROS dynamics: a multi-layered microfluidic chip for ecotoxicological studies on aquatic microorganisms

Olivier Martin, Christian Santschi, Volodymyr Koman, Nadia Rachel Von Moos

Reactive oxygen species (ROS) play an important role in the life of every cell, including cellular defense and signaling mechanisms. Continuous and quantitative ROS sensing can provide valuable information about the cell state, but it remains a challenge t ...

Effects of paternal and peripubertal stress on aggression, anxiety, and metabolic alterations in the lateral septum

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Nathalie Just, Guillaume Poirier

Early-life stress and biological predispositions are linked to mood and personality disorders related to aggressive behavior. We previously showed that exposure to peripubertal stress leads to increased anxiety-like behaviors and aggression against males a ...

The effects of stress during early postnatal periods on behavior and hippocampal neuroplasticity markers in adult male mice

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Aurélie Lattion

Infancy is a critical period for brain development. Emerging evidence indicates that stress experienced during that period can have long-term programming effects on the brain and behavior. However, whether different time periods represent different vulnera ...

Hippocampal neuroligin-2 links early-life stress with impaired social recognition and increased aggression in adult mice

Maria del Carmen Sandi Perez, Jocelin Grosse, Alexandre Claude Gustave Bacq

Early-life stress is a key risk factor for the development of neuropsychiatric disorders later in life. Neuronal cell adhesion molecules have been strongly implicated in the pathophysiology of psychiatric disorders and in modulating social behaviors associ ...

Stress and the social brain: Behavioral effects and neurobiological mechanisms

Maria del Carmen Sandi Perez

Stress often affects our social lives. When undergoing high-level or persistent stress, individuals frequently retract from social interactions and become irritable and hostile. Predisposition to antisocial behaviours — including social detachment and viol ...

Impaired hippocampal neuroligin-2 function by chronic stress or synthetic peptide treatment is linked to social deficits and increased aggression

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti

Neuroligins (NLGNs) are cell adhesion molecules that are important for proper synaptic formation and functioning and are critical regulators of the balance between neural excitation/inhibition (E/I). Mutations in NLGNs have been linked to psychiatric disor ...

CRHR1 links peripuberty stress with deficits in social and stress-coping behaviors

Maria del Carmen Sandi Perez, Vandana Veenit, Orbicia Riccio Wicht

Stressful life events during childhood and adolescence are important risk factors for the development of psychopathologies later in life. The corticotropin releasing hormone (CRH) and the CRH receptor 1 (CRHR1) have been implicated in the link between earl ...

Peripubertal stress-induced behavioral changes are associated with altered expression of genes involved in excitation and inhibition in the amygdala

Maria del Carmen Sandi Perez, Stamatina Tzanoulinou, Orbicia Riccio Wicht

Early-life stress is a critical risk factor for developing psychopathological alterations later in life. This early adverse environment has been modeled in rats by exposure to stress during the peripubertal period-that is, corresponding to childhood and pu ...

The interplay of conditional NCAM-knockout and chronic unpredictable stress leads to increased aggression in mice

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Orbicia Riccio Wicht

The neural cell adhesion molecule (NCAM) is a key regulator of brain plasticity. Substantial evidence indicates that NCAM is down-regulated by exposure to sustained stress and chronic stress seems to lead to increased aggression. In addition, constitutiona ...
