(Submitter supplied) Microenviromental niche characterization by comparative transcriptome profiling. The hypothesis tested in the present study was that unique properties of the perivascular niche within remyelinating white matter would create microenvironment that favor the alternative differentiation of oligodendrocyte precursor cells.

(Submitter supplied) The repair of white matter damage is of paramount importance for functional recovery after brain injuries.We report that interleukin-4 (IL-4) promotes oligodendrocyte regeneration and remyelination. IL-4 receptor expression was detected in a variety of glial cells after ischemic brain injury, including oligodendrocyte lineage cells. IL-4 deficiency in knockout mice resulted in greater deterioration of white matter over 14 days after stroke. more...

(Submitter supplied) We sequenced the transcriptome of young (6-8 week) and middle-aged (8-10 month old) C57BL/6 female mice that were naïve or had injured ventrolateral spinal cord white matter. We found several differentially expressed genes, many suggesting an altered immune response to injury with advancing age.

(Submitter supplied) Mouse cuprizone (CPZ ) model of experimental de- and remyelination was applied to mimic demyelination pathology of multiple sclerosis. In order to identify differentially expressed microRNAs involved in de- and remyelination, the affected areas of corpus callosum were isolated from mice exposed to CPZ and conducted an Agilent microarray analysis. To induce demyelination, CPZ was administrated for four weeks. more...

(Submitter supplied) Tissue progenitors maintain the integrity of organ systems through aging and stress. The brain’s white matter regions experience ischemic lesions and age-dependent degeneration. Brain white matter contains progenitors, oligodendrocyte precursor cells (OPCs), which can repair some insults. The response of OPCs to white matter ischemia and aging is not known. We characterized the response of OPCs to white matter stroke using OPC reporter mice, cell migration tracking, OPC specific RNA sequencing, and mechanistic studies in candidate biochemical pathways in the aged brain. more...

(Submitter supplied) MiR-125a-3p over-expression in OPCs impairs their differentiation into fully mature oligodendrocytes. We performed a whole microarray profiling to identify new miR-125a-3p direct targets and altered signaling pathways responsible for its the detrimental effect on oligodendrocyte maturation.

(Submitter supplied) CSF1 expression in the central nervous system (CNS) increases in response to a variety of stimuli, and CSF1 is overexpressed in many CNS diseases. In young adult mice we previously showed that CSF1 overexpression in the CNS caused proliferation of IBA1+ microglia without promoting expression of M2 polarization markers. Here we further examine the impacts of increased CSF1 levels in the brain. As CSF1 over-expressing mice age, IBA1+ cell numbers are constrained by a decline in proliferation rate. more...

(Submitter supplied) Recent single-cell RNA sequencing studies have revealed distinct microglial states in development and disease. These include proliferative region-associated microglia (PAM) in developing white matter and disease-associated microglia (DAM) prevalent in various neurodegenerative conditions. PAM and DAM share a similar core gene signature and other functional properties. However, the extent of the dynamism and plasticity of these microglial states, as well as their functional significance, remains elusive, partly due to the lack of specific tools. more...

(Submitter supplied) Multiple sclerosis (MS) is a neuroimmune disorder characterized by inflammation, CNS demyelination, and progressive neurodegeneration. Chronic MS patients exhibit impaired remyelination capacity, partly due to the changes that oligodendrocyte precursor cells (OPCs) undergo in response to the MS lesion environment. The cytokine tumor necrosis factor (TNF) is present in the MS affected CNS and has been implicated in disease pathophysiology. more...

(Submitter supplied) In MS pathophysiology, soluble tumor necrosis factor (TNF) has been attributed detrimental functions, whereas transmembrane TNF promotes neurorepair primarily by activating TNF receptor 2 (TNFR2). Here we investigate the role of TNFR2 in microglia and peripheral monocyte/macrophages in EAE using novel cell-specific conditional knockouts. We show that microglial TNFR2 ablation leads to early onset of EAE, with increased CNS leucocyte infiltration, T cell activation, and demyelination. more...

(Submitter supplied) Background: Multiple sclerosis (MS) is an inflammation-mediated demyelinating disease of the central nervous system, which eventually results in secondary axonal degeneration due to remyelination failure. Successful remyelination is orchestrated by astrocytes (ASTRs) and requires sequential activation, recruitment, and maturation of oligodendrocyte progenitor cells (OPCs). In both MS and experimental models, remyelination is more robust in grey matter (GM) than white matter (WM) that is likely related to local differences between GM and WM lesions. more...

(Submitter supplied) Following all types of neurological injury, resident macrophages are activated locally, and blood-derived macrophages are recruited. Distinguishing the role of resident and blood-derived macrophages is complicated by the difficulty in distinguishing between these cell types because they mostly express the same molecular markers in a diseased state. To begin to understand the complexity of functions of resident and blood-derived macrophages following acute injury in the central nervous system (CNS) we ablated microglia, but not infiltrating macrophages, to determine their contribution following lysolecithin-induced demyelination .

(Submitter supplied) To investigate transcriptomic drivers of human myelination, immunodeficient mice were chimerized with fetal derived hGPCs at P1, sacrified at 36 weeks, and hGPCs were extracted for RNA-Sequencing via FACS. Mice were either fed a control diet for the entireity of their lives or a demyelinating diet beginning at 12 weeks of age until 24 weeks, when they were transitioned to a control diet to allow for remyelination to begin.
