Developmental outcomes of early adverse care on amygdala functional connectivity in nonhuman primates / Elyse L. MORIN in Development and Psychopathology, 32-5 (December 2020)

Titre : Developmental outcomes of early adverse care on amygdala functional connectivity in nonhuman primates Type de document : Texte imprimé et/ou numérique Auteurs : Elyse L.

This study used a translational macaque model of infant maltreatment in which the adverse experience occurs in the first months of life, during intense maturation of amygdala circuits important for stress and emotional regulation. Thus, we examined the developmental impact of maltreatment on amygdala functional connectivity (FC) longitudinally, from infancy through the juvenile period. Using resting state functional magnetic resonance imaging (MRI) we performed amygdala-prefrontal cortex (PFC) region-of-interest and exploratory whole-brain amygdala FC analyses. The latter showed (a) developmental increases in amygdala FC with many regions, likely supporting increased processing of socioemotional-relevant stimuli with age; and (b) maltreatment effects on amygdala coupling with arousal and stress brain regions (locus coeruleus, laterodorsal tegmental area) that emerged with age. Maltreated juveniles showed weaker FC than controls, which was negatively associated with infant hair cortisol concentrations. Findings from the region-of-interest analysis also showed weaker amygdala FC with PFC regions in maltreated animals than controls since infancy, whereas bilateral amygdala FC was stronger in maltreated animals. These effects on amygdala FC development may underlie the poor behavioral outcomes associated with this adverse experience.

Inflammation has been proposed as a mechanism through which early adverse experiences become biologically embedded. However, most studies providing evidence for the link between early adverse exposures and inflammation have been retrospective or cross-sectional in design, or did not assess inflammation immediately after maltreatment in young children. In the present study we investigated the association between childhood maltreatment and salivary C-reactive protein (CRP) concentrations in a population of N = 173 children, 3-5 years of age, who were recruited in the immediate aftermath of maltreatment and followed-up longitudinally every 6 months over a period of 2 years. We found that the association between maltreatment and CRP concentrations was significantly moderated by child sex, such that in girls, CRP concentrations were higher in the maltreated compared to the control group, and this difference was stable across the 2-year follow-up-period, while in boys, there was no association between maltreatment and CRP. Our findings suggest that the effect of maltreatment on inflammation may already emerge right after exposure at a very young age in girls and manifest over time. Our study provides important evidence for the development of personalized, early interventions strategies targeting the early-life period.
