Comparison of cerebrospinal fluid proteomics between Demyelinating disease and non-inflammatory neurological controls

ABSTRACT: Demyelinating disease is a disease of the nervous system in which the nerve demyelinating is the main or primary lesion, and the axon, cell body and glia are relatively lightly damaged. It can occur in the central nervous system or the peripheral nervous system. The demyelinating diseases of central nervous system are represented by multiple sclerosis (MS) and neuromyelitis optica (NMO) while Guillain-Barre Syndrome (GBS) is a demyelinating disease of the peripheral nervous system. We aimed to identify the key proteins in demyelinating disease and describe the proteomic pattern of MS, GBS and NMO. This study used high-resolution liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS), in combination with quantitative 10-plex tandem mass tag labeling, to profile protein changes in MS, GBS and NMO.

Single cell RNA analysis reveals the complex heterogeneity of CD4+ T cells in chronic neuroinflammation

Project description:Multiple sclerosis (MS) is a severe chronic inflammatory disease of the central nervous system (CNS) that leads to disability in young adults. T lymphocytes are a key component of lesion pathology throughout the disease course. Here we used the animal model experimental autoimmune encephalomyelitis (EAE) to conduct an unbiased characterization of CD4+ T cells in acute and chronic EAE.

Epitranscriptomic m6A Regulation of Axon Regeneration in the Adult Mammalian Nervous System

Project description:N6-methyladenosine (m6A) affects multiple aspects of mRNA metabolism and regulates developmental transitions by promoting mRNA decay. Little is known about the role of m6A in the adult mammalian nervous system. Here we report that sciatic nerve lesion elevates levels of m6A-tagged transcripts encoding many regeneration-associated genes and protein translation machinery components in the adult mouse dorsal root ganglion (DRG). Single base resolution m6A-CLIP mapping further reveals a dynamic m6A landscape in the adult DRG upon injury. Loss of either m6A methyltransferase complex component Mettl14 or m6A-binding protein Ythdf1 globally attenuates injury induced protein translation in adult DRGs and reduces functional axon regeneration in the peripheral nervous system in vivo. Furthermore, Pten deletion-induced axon regeneration of retinal ganglion neurons in the adult central nervous system is attenuated upon Mettl14 knockdown. Our study reveals a critical epitranscriptomic mechanism in promoting injury-induced protein synthesis and axon regeneration in the adult mammalian nervous system.

Gene Expression Profiling of Resting and Activated CD4+ T Cells in Patients with Multiple Sclerosis

Project description:Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system with varying disease course as well as response to treatment. Thus, biomarkers for personalized treatment are highly needed. We tested the hypothesis that in vitro activation of CD4+ T cells from MS patients could reveal pathways containing potential biomarkers and found a dysregulated dynamic gene response upon activation. By integrating our findings with data from genome-wide association studies and using a network-based approach, we constructed a highly connected MS gene module disclosing cell activation and chemotaxis as central components.

CLIPseq of hnRNP A1 from the spinal cords of mice with experimental autoimmune encephalomyelitis

Project description:Experimental autoimmune encephalomyelitis (EAE) is a mouse model for multiple sclerosis (MS) a chronic autoimmune disease of the central nervous system. We have observed dysfunction of the RNA binding protein hnRNP A1 in neurons from the brains of patients with MS, and the spinal cords of mice with EAE. Here, we sought to characterize the consequences of EAE-induced dysfunction of hnRNP A1 on the RNAs it binds by using CLIPseq to establish both the normal central nervous system RNA binding profile of hnRNP A1 in the spinal cords of naive mice, and any alterations to the binding profile of hnRNP A1 in the spinal cords of mice with EAE.

Brain macrophages adopt distinct profiles prior to demyelination in multiple sclerosis

Project description:Multiple sclerosis is a disease of the central nervous system (CNS) that is characterized by inflammation and focal areas of demyelination, ultimately resulting in axonal degradation and neuronal death. Several lines of evidence point towards a role for microglia and other CNS-associated macrophages in disease initiation and progression, but exactly how lesion formation is triggered is currently unknown. Here, we characterized early changes in MS brains through transcriptomic analysis of normal appearing white matter (NAWM). We found that NAWM was already characterized by expression of inflammatory genes and that expression of genes associated with stress-response was increased, likely as a result of changes in the macrophage compartment. Single cell RNA sequencing analysis confirmed an early stress response in brain macrophages and identified specific macrophage subsets that associate with different stages of demyelinating lesions. These data provide insight into early changes in MS brains that may provide therapeutic targets in order to limit lesion development and demyelination.

Histamine H3 Receptor Integrates Peripheral Inflammatory Signals in the Neurogenic Control of Immune Responses and Autoimmune Disease Susceptibility

Project description:Histamine H3 receptor (Hrh3/H3R) is primarily expressed by neurons in the central nervous system (CNS) where it functions as a presynaptic inhibitory autoreceptor and heteroreceptor. Previously, we identified an H3R-mediated central component in susceptibility to experimental allergic encephalomyelitis (EAE), the principal autoimmune model of multiple sclerosis (MS), related to neurogenic control of blood brain barrier permeability and peripheral T cell effector responses. Furthermore, we identified Hrh3 as a positional candidate for the EAE susceptibility locus Eae8. Here, we characterize Hrh3 polymorphisms between EAE-susceptible and resistant SJL and B10.S mice, respectively, and show that Hrh3 isoform expression in the CNS is differentially regulated by acute peripheral inflammatory stimuli in an allele-specific fashion. Next, we show that Hrh3 is not expressed in any subpopulations of the immune compartment, and that secondary lymphoid tissue is anatomically poised to be regulated by central H3R signaling. Accordingly, using transcriptome analysis, we show that, inflammatory stimuli elicit unique transcriptional profiles in the lymph nodes of H3RKO mice compared to WT mice, which is indicative of negative regulation of peripheral immune responses by central H3R signaling. These results further support a functional link between the neurogenic control of T cell responses and susceptibility to CNS autoimmune disease coincident with acute and/or chronic peripheral inflammation. Pharmacological targeting of H3R may therefore be useful in preventing the development and formation of new lesions in MS, thereby limiting disease progression. 8 pooled samples from at least 3 mice per pool

Gene expression data: Plasmacytoid dendritic cells (pDCs) of healthy donors and MS patientes before and after IFN beta treatment

Project description:Multiple Sclerosis (MS) is an immune-mediated chronic inflammatory disease affecting the central nervous system. The cause of MS is not known and the mechanism of IFN-beta, a disease-modifying treatment (DMT) approved for MS, is not well-understood. Oligonucleotide microarrays were used to study gene expression in plasmacytoid denditic cells (pDCs) which are antigen-presenting cells implicated in MS pathogenesis. We analyzed gene expression in pDCs of healthy controls, untreated and IFN-beta treated MS patients. We were able to identify 60 genes which were abnormally expressed in untreated MS patients and were corrected after treatment with IFN-beta.

Next Generation Sequencing of Pattern II Demyelinating Brain Lesions from a Multiple Sclerosis Patient

Project description:Multiple sclerosis is a chronic inflammatory demyelinating disease of the central nervous system with marked heterogeneity in several aspects including pathological processes. Four histopathological patterns of MS have been described. Pattern II is characterized by infiltrating macrophages and T-cells and by antibody and complement deposition. Transcriptome analysis of three patern II demyelinating brain lesions from a multiple sclerosis patient using RNA sequencing demonstrated the presence of mRNA transcripts for genes specific of activated macrophages, T and B cells as well as genes coding for immunoglobulins, complement proteins and some pattern II associated proteins, providing additional evidence supporting pattern II demyelination. Examination of 3 different demyelinating lesions identified by Immunohistopathology.
