Expression data from mouse meningies - home cage (HC) and chronic social defeat (SD) stress mice

Project description:CSD stress leads to transcriptional changes in the meninges indicative of increased immune system activation. We have characterized lymphopenia (B cell depletion) and possible fibroblast contribution to neutrophil trafficking at arachnoid barrier cells (ABCs) with this data set.

Differential gene expression in peripheral blood leukocytes from mice subject to repeated social defeat

Project description:This study tested the effects of repeated social defeat (RSD) on gene expression in peripheral blood mononuclear cells (PBMC), and examined the extent to which these effects were abrogated by depletion of CD11b+ cells (monocytes). Study Type: Risk prediction Gene expression profiling was carried out on peripheral blood mononuclear cell (PBMC) mRNA samples collected from 18 mice randomized to either 6 cycles of repeated social defeat (RSD, n=9) or to home cage control (HCC, n=9) conditions. PBMC samples were pooled into 3 groups of n=3 samples in each condition, and Illumina Mouse Ref-8 BeadArray assays were performed on approximately 1 million total PBMC and 1 million PBMC from which CD11b+ cells were immunomagnetically depleted by MACS. The primary research questions are 1) whether expression of pro-inflammatory genes is altered by RSD, and 2) whether depletion of CD11b+ cells (monocytes) abrogates these effects.

Effect of propranolol on differential gene expression in peripheral blood monocytes from mice subject to repeated social defeat

Project description:This study tested the effects of repeated social defeat (RSD) on gene expression in peripheral blood monocytes and examined the extent to which these effects were abrogated by the beta-adrenergic antagonist propranolol. Study Type: Risk prediction Gene expression profiling was carried out on peripheral blood monocyte mRNA samples collected from 36 mice randomized to either 6 cycles of repeated social defeat (RSD, n=18) or to parallel home cage control (HCC, n=18) conditions. Within each condition (RSD vs HCC), 9 animals were treated with the beta-adrenergic antagonist propranolol and 9 were treated with an equivalent volume of vehicle. After 6 cycles of RSD or parallel HCC, blood samples were pooled into groups of n=3 samples in each condition, and Illumina Mouse Ref-8 BeadArray assays were performed on RNA from approximately 1 million CD11b+ peripheral blood mononuclear cells (i.e., monocytes) which were immunomagnetically isolated by MACS. The primary research questions are 1) whether expression of pro-inflammatory genes is altered by RSD, and 2) whether treatment with propranolol abrogates these effects.

Chronic social defeat alters brain vascular-associated cell gene expression patterns leading to vascular dysfunction and immune system activation

Project description:Brain vascular integrity is critical for brain health, and its disruption is implicated in many brain pathologies, including psychiatric disorders. Brain-vascular barriers are a complex cellular landscape composed of endothelial, glial, mural, and immune cells. Yet currently, little is known about these brain vascular-associated cells (BVACs) in health and disease. Previously, we have demonstrated that 14 days of chronic social defeat (CSD), a mouse paradigm that produces anxiety and depressive-like behaviors, causes cerebrovascular damage in the form of scattered microbleeds. Here, we developed a technique to isolate barrier-related cells from the mouse brain and subjected the cells to single-cell RNA sequencing. Using this isolation technique, we found an enrichment in BVAC populations, including distinct subsets of endothelial and microglial cells. In CSD compared to home-cage control, differential gene expression patterns disclosed biological pathways involving vascular dysfunction, vascular healing, and immune system activation. Overall, our work demonstrates a unique technique to study rare BVAC populations from fresh brain tissue and suggests that neurovascular dysfunction is a key driver of psychosocial stress-induced brain pathology.

Malaria Hepatocyte HC-04.J7 Project

Project description:Characterization of three hepatocyte cell lines (2 parental and 1 clone), under two different media conditions. Parental cell lines HepG2 and HC-04, single cell cloned from HC-04 defined as HC-04.J7. The goal of the project initially was to investigate the invasion of hepatocytes by Plasmodium falciparum sporozoites, and once found that the HC-04 cell had a higher invasion than HepG2, single cell isolates were generated from HC-04 before being expanded. The resulting HC-04.J7 isolate further improved the invasion rate. Transcriptomic and proteomic data sets were generated from all cell lines in both media, than analyzed for potential receptors or biochemical pathways that play a role in the increased invasion of HC-04 and specifically, HC-04.J7.

Expression data from ileum of mice suffered from subchronic and mild social defeat stress

Project description:This study aimed to investigate the effects of depression on transcriptome in ileum using a subchronic and mild social defeat stress (sCSDS) model. In addition to exhibiting social deficit and hyperphagia-like behavior, the sCSDS mice keep much more water in their body than control mice. In order to investigate the effect of social defeat stress on not only central nervous system but also function of gastrointestinal tract, the gene expression in ileum of stressed mice was compared with control mice. We used microarrays to detail the gene expression after 10 days of social defeat stress and identified distinct classes of down-regulated genes during this process. The duration of physical contacts was set at 5 min after the first attack bite at Day 1, and then was reduced 0.5 min per day from Day 2 to Day 10.
