Proteomics of cerebrospinal fluid microvesicles

ABSTRACT: Comprehensive proteomic dataset of cerebrospinal fluid (CSF) microvesicles. The aim of this study is to deeply characterize the protein content of microvesicles (MVs) isolated from human cerebrospinal fluid.

Journal of proteomics 20140424

Extracellular vesicles (EVs) are present in human cerebrospinal fluid (CSF), yet little is known about their protein composition. The aim of this study is to provide a comprehensive analysis of the proteome of CSF EVs by electron microscopy and high resolution tandem mass spectrometry (MS/MS) in conjunction with bioinformatics. We report an extensive catalog of 1315 proteins identified in EVs isolated from two different CSF pools by ultracentrifugation, including 230 novel EV proteins. Out of 13 ...[more]

Phosphoproteome Analysis of Cerebrospinal Fluid Extracellular Vesicles in Primary Central Nervous System Lymphoma

Project description:Primary central nervous system lymphoma(PCNSL) is a rare extra-nodal non-Hodgkin’s lymphoma and accounts for 3%-4% of central nervous system tumors. Recent studies have highlighted the importance of cerebrospinal fluid derived extracellular vesicles in PCNSL. Extracellular vesicles(EVs) are nanoscale vesicles with bilayer lipid membrane released by almost all cell types. EVs are present in body fluids, including urine, blood and CSF. Cerebrospinal fluid(CSF) is a colorless fluid that surrounds the brain and spinal cord and acts as lymph in the central nervous system. CSF-derived EVs contain proteins from neurons, oligodendrocytes, astrocytes and microglias. Studies of CSF EVs are mainly limited by the amount of EVs isolated from per milliliter of CSF and the volume of CSF acquired from one patient. Here, we provide a label-free quantitative phospho-proteome profiling of EVs separated from PCNSL and non-PCNSL CSF samples by an earlier introduced functional magnetic beads called EVTRAP together with highly sensitive timsTOF Pro.

Project description:Multiple sclerosis biomarker discovery in pooled cerebrospinal fluid (CSF) using glycopeptide enrichment, TMT labeling and LC-MS/MS. Comparing 3 pools of CSF from relapsing-remitting MS (RRMS) patients to 3 pools of CSF from patients with other neurological diseases (OND). To reveal protein groups and networks affected by MS and to look at correlation between a glyco and a global approach.

Human cerebrospinal fluid autoantibody lipid microarray profiling (Fig. 1A)

Project description:Lipids comprise 70% of the myelin sheath, and autoantibodies against lipids may contribute to the demyelination that characterizes multiple sclerosis (MS). We used lipid antigen microarrays and lipid mass spectrometry to identify bona fide lipid targets of the autoimmune response in MS brain and an animal model of MS to explore the role of the identified lipids in autoimmune demyelination. We found that autoantibodies in MS target a phosphate group in phosphatidylserine and oxidized phosphatidylcholine derivatives. Administration of these lipids ameliorated experimental autoimmune encephalomyelitis by suppressing activation and inducing apoptosis of autoreactive T cells, effects mediated by the lipids' saturated fatty-acid side chains. Thus, phospholipids represent a natural anti-inflammatory class of compounds that have potential as novel therapeutics for MS. Fig. 1A. Lipid-array profiling of IgG+IgM antibody reactivity in cerebrospinal fluid (CSF) samples from MS patients (relapsing remitting MS; secondary progressive MS; primary progressive MS), healthy controls, and other neurological disease controls. Lipid hits with the lowest FDR (q=0.048) were clustered according to their reactivity profiles. 48 different lipids were custom-spotted in duplicate using the CAMAG Automatic TLC Sampler (ATS4) robot to spray 200 nl of 10 to 100 pmol of lipids onto PVDF membranes affixed to the surface of microscope slides. The slides were probed with cerebrospinal fluid (CSF) from 59 human patient samples. 60 slides total: 18 relapsing-remitting MS, 14 secondary-progressive MS, 1 primary-progressive MS, 21 other neurological disease, 5 healthy control, 1 secondary Ab alone (not included in this submission). CSF diluted 1/10. HRP-conjugated secondary Ab (goat anti-human IgM/IgG) diluted 1/8000. ECL for 3 minutes.

Single cell RNA sequencing reveals microglia-like cells in cerebrospinal fluid during virologically suppressed HIV

Project description:Using single cell RNA sequencing (scRNA-seq) on cerebrospinal fluid (CSF) and blood from adults with HIV, we identified a rare (<5% of cells) subset of myeloid cells that are found only in CSF and that present a gene expression signature that overlaps significantly with neurodegenerative disease associated microglia

Single-cell RNA and TCR sequencing of IgG4-related disease cerebrospinal fluid

Project description:Immunoglobulin G4 (IgG4)-related disease (IgG4-RD) is a fibroinflammatory disorder signified by aberrant infiltration of IgG4-restricted plasma cells in a variety of organs. Clinical presentation is heterogeneous and pathophysiological mechanisms of IgG4-related autoimmunity remain elusive. Secondary parenchymal lesions of IgG4-RD in the central nervous system (CNS) are rare and there are very few cases of IgG4-RD with isolated CNS manifestation. Patients suffering from IgG4-RD frequently require prolonged treatment with glucocorticoids and are often unable to taper these medications. By leveraging single-cell sequencing of the cerebrospinal fluid (CSF) of a patient with an unusual inflammatory intracranial pseudotumor we provide novel insights into the immuno-pathophysiology of IgG4-RD by illustrating an IgG4-RD-associated polyclonal T cell response in the CSF and multifaceted cell-cell interaction between immune cell subsets and pathogenic B cells.

Human Cerebrospinal Fluid modulates pathways promoting Glioblastoma malignancy

Project description:Glioblastoma (GBM) is the most common and devastating primary cancer of the central nervous system in adults. High grade gliomas are able to modify and respond to the brain microenvironment. When GBM tumors infiltrate the Subventricular zone (SVZ) they have a more aggressive clinical presentation than SVZ-distal tumors. We suggest that cerebrospinal fluid (CSF) contact contributes to enhance GBM malignant characteristics in these tumors. We evaluated the impact of human CSF on GBM, performing a transcriptome analysis on human primary GBM cells exposed to CSF of cancer and non cancer origin to measure changes in gene expression profile associated with increased malignancy and their clinical relevance on disease outcome.

Cerebrospinal fluid cell-free DNA methylomes subtyping pediatric medulloblastoma

Project description:Medulloblastoma (MB) is an embryonal tumor of the cerebellum and a highly malignant childhood brain tumor. Cell-free circulating tumor DNA (ctDNA) from the cerebrospinal fluid (CSF) of patients with brain tumors faithfully represent genomic alterations of brain tumors. Distinct epigenetic signatures among subgroups of MB allow us to detect epigenetic alterations in CSF to aid classify and guide therapy of MB tumors. Here, we evaluate DNA methylation of ctDNA derived from small amount of CSF (200 µL) and matched tumor DNA from four subtypes of MB patients. We find highly concordance of DNA methylation between CSF ctDNA and tumor DNA in a subtype manner. Our results show that CSF ctNDA methylation can be a minimal invasive precisely method to assess epigenetic alterations of MB in a subtype manner, which is complementary to current diagnoses of MB tumors.
