Single-nucleus profiling of adult mice subventricular zone after blast-TBI

ABSTRACT: To elucidate molecular features of the cells of Sub-ventricular Zone (SVZ), their progeny at each differentiation stage, and surrounding cells in SVZ under blast wave-induced changes, cells were profiled from matched SVZ of 3 mice that had received blast injury and 3 controls（The controls sequencing profile can be assessed in GEO at GSM5938054）.Cell type specific gene expression responding to (blast-related traumatic brain injury, bTBI) were revealed, some of which were closely associated with pathogenesis post-injury. Furthermore, the diverse cell to cell interaction networks uncovered an array of cellular processes under bTBI. Our gene expression atlas provides extensive resources for future researches regarding bTBI induced pathogenesis, its therapeutic interventions or diagnostic tests.

Blast preconditioning protects retinal ganglion cells and reveals targets for prevention of neurodegeneration following blast-mediated TBI

Project description:Purpose: The purpose of this study was to examine the effect blast preconditioning on the structure and function of retinal ganglion cells (RGC), and to identify molecular pathways that contribute to RGC loss. Methods: To examine the effect of blast-preconditioning three groups of mice were analyzed, including those 1) subjected to sham injury followed by one single 20 PSI injury one week later, 2) mice exposed to two low intensity preconditioning blast exposures separated by one week (5 PSI, 5 PSI) and 3) mice exposed to a preconditioning injury (5 PSI) followed by a single 20 PSI blast exposure one week later. RNAseq analysis was used to identify transcriptional changes between groups. Conclusions: Preconditioning protects RGC from blast injury. Protective effects appear to involve changes in kynurenine-3-monooxygenase activity, whose inhibition is also protective.

The Sub-ventricular Zone in Mild Traumatic Brain Injury at Single-cell Resolution

Project description:The subventricular zone (SVZ) is a neurogenetic niche that contributes to homeostasis and repair after brain injury. However, effects of mild traumatic brain injury (mTBI) on genomewide gene expression in the SVZ remain largely unexplored. To address this issue, we investigated the single-nucleus transcriptomic profiles of the SVZ after mTBI. 18 distinct clusters were yielded via unsupervised clustering of the transcriptomic profiles. Cell type specific gene expression responding to mTBI were revealed, some of which were closely associated with pathogenesis post-injury. Furthermore, the diverse cell to cell interaction networks uncovered an array of cellular processes under mTBI. Also, we reported novel lineage trajectories and molecular hallmarks that govern the neurogenesis. Our gene expression atlas provides extensive resources for future researches regarding mTBI induced pathogenesis, its therapeutic interventions or diagnostic tests.

Defining the microglial transcriptome in the rat subventricular zone (SVZ) after neonatal hypoxia-ischemia (HI).

Project description:Purpose: Recent findings indicate a regulatory role of microglia on neurogenesis in the SVZ in health and disease. Microglia in the early postnatal SVZ are not fully maturated and may react differently than adult microglia to injury. We sought to investigate the impact of cortico-striatal neonatal HI injury on the microglial phenotype in the early postnatal SVZ. Results: In comparison to sham SVZ microglia, HI SVZ microglia upregulate both pro- and anti-inflammatory genes as well as neurotrophic genes. HI SVZ microglia do not adopt a M1 or M2 polarization state, but instead share commonly expressed genes with microglia in rodent models of neurodegenerative diseases.

Project description:Male Long Evans rats aging 10-12 weeks were exposed to repeated blast overpressure and then went through behavioral tests for anxiety and fear conditioning. After 1-1.5 months (sub-acute) or 12-13 months (chronic), amygdala tissue specimens from all animals were collected. RNA-seq was used to measure transcriptome-wide gene expression of sham and blast animals at different timepoints. The study identified changes in the amygdalar transcriptome and associated anxiety-related phenotypic outcomes related to both blast exposure and aging, which may play a role in the long-term pathological consequences of mTBI.

Single cell expression profiling of murine subventricular zone in adult brain three days after focal celebral ischemia

Project description:Ischemic stroke is a serious medical condition that leads to the onset of neurological symptoms such as loss of motor and cognitive functions. Focal cerebral ischemia (FCI) occurs due to the interrupted blood supply to the site of injury, resulting in the demise of brain cells. The subventricular zone (SVZ) is a source of stem and progenitor cells (NS/PCs), which proliferate and differentiate in multiple cell types in order to substitute the injured tissue. We isolated cells from the SVZ and the adjacent striatum three days after middle cerebral artery occlusion (MCAO) in order to map cellular changes and NS/PCs plasticity in adult brain upon injury. Expression profiling of the isolated tissue at the single cell level enables the identification of cell population subtypes in the region and their characteristic gene expression.
