Early life stress perturbs the maturation of microglia in the developing hippocampus [P14]

ABSTRACT: In this study we hypothesize that early life stress perturbs the normal function of microglia in the developing hippocampus and that this effect is responsible for the ability of early life tress to disrupt normal synaptic maturation, myelination, and axonal growth in the developing hippocampus. To test this hypothesis we used the mouse immune panel from NanoString in order to identify immune-related genes whose expression is modified by BDS, a mouse model of early life stress, in microglia isolated from the hippocampus of 14-day old male pups. This project is part of a manuscript that is currently under preparation (Delpech J.C. et al. Early life stress perturbs the maturation of microglia in the developing hippocampus, Brain, Behavior and Immunity, 2016)

Early life stress perturbs the maturation of microglial in the developing hippocampus [P28]

Project description:In this study we hypothesize that early life stress perturbs the normal function of microglial in the developing hippocampus and that this effect is responsible for the ability of early life tress to disrupt normal synaptic maturation, myelination, and axonal growth in the developing hippocampus. To test this hypothesis we used the mouse immune panel from NanoString in order to identify immune-related genes whose expression is modified by BDS, a mouse model of early life stress, in microglia isolated from the hippocampus of 28-day old male pups. This project is part of a manuscript that is currently under preparation (Delpech J.C. et al.

Early life stress perturbs the maturation of microglia in the developing hippocampus [development]

Project description:The goal of this project was to identify genes whose expression is modified by age in microglia isolated from the hippocampus of 14 and 28-day old control mice (i.e. normally developing mice). To accomplish this we used two independent cohorts of control mice and identified a list of 76 genes that were significantly regulated by age (p< 0.05) in both cohorts. Data for cohort 1 were extracted from gene expression of P14 and P28 control mice available in the BDS-P14-male series (GSE81036) and BDS-P28-male series (GSE81037). Data for cohort 2 are available in this series. These data are summarized also in Table S3 in Delpech J.C. et al. Early life stress perturbs the maturation of microglial cells in the developing hippocampus, Brain, Behavior and Immunity, 2016 (in preparation).

Reduced microglial Trem2 levels is associated with abnormal synaptic pruning in the developing hippocampus of mice exposed to early life stress

Project description:The goal of this project was to assess the effects of two paradigms of early life stress on microglial gene expression in the developing hippocampus of 17-day old mice. Sixty thousands microglia were isolated from the hippocampus of 17-day old mice pups exposed to control (CTL), limited bedding (LB) or unpredictable postnatal stress (UPS) conditions and were processed to assess gene expression using the mouse Glia panel (Nanostring, Cat # XT-Mm Glial profiling CSO).

RNA-seq of mouse brain tissue investigating the effect of absence of microglia in the developing brain

Project description:Microglia, brain-resident macrophages, have been proposed to play an active role in synaptic refinement and maturation, influencing plasticity and circuit-level connectivity. Using a genetically modified mouse which lacks microglia (Csf1r ∆FIRE/∆FIRE), we investigate the effect on gene expression of the presence or absence of microglia in the developing mouse brain.

Single-nuclei sequencing of mouse brain tissue and single-cell sequencing of FACS-sorted mouse astrocytes, investigating the effect of absence of microglia in the developing brain

Project description:Microglia, brain-resident macrophages, have been proposed to play an active role in synaptic refinement and maturation, influencing plasticity and circuit-level connectivity. Using a genetically modified mouse which lacks microglia (Csf1r ∆FIRE/∆FIRE), we investigate the effect on gene expression in particular cell types of the presence or absence of microglia in the developing mouse brain.

Early life stress in fathers impairs synaptic plasticity in the offspring - brain collected after acute swim stress

Project description:We show that traumatic stress experienced by males in early postnatal life impairs memory in their offspring, blocks long-term potentiation (LTP) and favors long-term depression (LTD). These effects are accompanied by suppression of key molecular pathways involved in neuronal plasticity both at rest and after acute stress. Male mice were exposed to chronic traumatic stress in early postnatal life and were later bred to naM-CM-/ve females to produce second-generation offspring. Memory performance was evaluated in the offspring, and synaptic plasticity was examined in the hippocampus and the amygdala, brain areas important for memory formation. The two groups tested were 1: offspring of fathers which were stressed (MSUS - maternal separation unpredictable stress) and 2: offspring of non-stressed fathers (control). Genome-wide gene expression in hippocampus of these two groups was assessed at rest and after acute stress (this study).
