Programming effects of peripubertal stress on spatial learning

Maria del Carmen Sandi Perez, Cristina Marquez Vega, 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 ...

Peripuberty stress leads to abnormal aggression, altered amygdala and orbitofrontal reactivity and increased prefrontal MAOA gene expression

Pierre Magistretti, Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Didier Trono, Anna Claire Groner, Cristina Marquez Vega, Guillaume Poirier

Although adverse early life experiences have been found to increase lifetime risk to develop violent behaviors, the neurobiological mechanisms underlying these long-term effects remain unclear. We present a novel animal model for pathological aggression in ...

Personality traits in rats predict vulnerability and resilience to developing stress-induced depression-like behaviors, HPA axis hyper-reactivity and brain changes in pERK1/2 activity

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Jorge Eduardo Castro Cifuentes, Cristina Marquez Vega, Shanaz Diessler

Emerging evidence indicates that certain behavioral traits, such as anxiety, are associated with the development of depression-like behaviors after exposure to chronic stress. However, single traits do not explain the wide variability in vulnerability to s ...

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

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Xavier Fontana, Basira Salehi, Cristina Marquez Vega, Vandana Veenit, Guillaume Poirier

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 ...

Differential impact of polysialyltransferase ST8SiaII and ST8iaIV knockout on social interaction and aggression

Maria del Carmen Sandi Perez, Reto Bisaz, Cristina Marquez Vega, Martina Fantin

Previous studies using neuronal cell adhesion molecule (NCAM) -/- knockout (KO) mice provided evidence for a role of NCAMs in social behaviors. However, polysialic acid (PSA), the most important post-translational modification of NCAM, was also absent in t ...

Role of the amygdala in antidepressant effects on hippocampal cell proliferation and survival and on depression-like behavior in the rat

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Jorge Eduardo Castro Cifuentes, Cristina Marquez Vega, Guillaume Poirier

The stimulation of adult hippocampal neurogenesis by antidepressants has been associated with multiple molecular pathways, but the potential influence exerted by other brain areas has received much less attention. The basolateral complex of the amygdala (B ...
