Identification of protein networks involved in the disease course of experimental autoimmune encephalomyelitis, an animal model of multiple sclerosis.

A more detailed insight into disease mechanisms of multiple sclerosis (MS) is crucial for the development of new and more effective therapies. MS is a chronic inflammatory autoimmune disease of the central nervous system. The aim of this study is to identify novel disease associated proteins involved in the development of inflammatory brain lesions, to help unravel underlying disease processes.

Leukemia inhibitory factor induces an antiapoptotic response in oligodendrocytes through Akt-phosphorylation and up-regulation of 14-3-3.

Leukemia inhibitory factor (LIF) promotes the survival of oligodendrocytes (OLG) both in vitro and in an animal model of multiple sclerosis. Here, we show that LIF protects mature rat OLG cultures selectively against the combined insult of the proinflammatory cytokines interferon-gamma and tumor necrosis factor-alpha, but it does not protect against oxidative stress nor against staurosporine induced apoptosis. We further demonstrate that LIF activates the janus kinase (JAK)/signal transducer and activator of transcription 3 (STAT3) and the phosphatidylinositol 3 kinase/Akt pathway in mature OLG.

Characterization of mature rat oligodendrocytes: a proteomic approach.

Oligodendrocytes are glial cells responsible for the synthesis and maintenance of myelin in the central nervous system (CNS). Oligodendrocytes are vulnerable to damage occurring in a variety of neurological diseases. Understanding oligodendrocyte biology is crucial for the dissemination of de- and remyelination mechanisms.

Gel-free analysis of the human brain proteome: application of liquid chromatography and mass spectrometry on biopsy and autopsy samples.

This paper reports on the findings of the Biomedical Research Institute, as one of the participants in the pilot study of the HUPO Brain Proteome Project. A biopsy and autopsy study sample derived from human brain was distributed among the participants for proteomic analysis. In our laboratory, attention was focused on protein identification using the bottom-up shotgun approach.

Lumbar cerebrospinal fluid proteome in multiple sclerosis: characterization by ultrafiltration, liquid chromatography, and mass spectrometry.

Neurological diseases, including multiple sclerosis (M.S.), often provoke changes in the functioning of the endothelial and epithelial brain barriers and give rise to disease-associated alterations of the cerebrospinal fluid (CSF) proteome.

The structural proteome of Pseudomonas aeruginosa bacteriophage phiKMV.

The structural proteome of phiKMV, a lytic bacteriophage infecting Pseudomonas aeruginosa, was analysed using two approaches. In one approach, structural proteins of the phage were fractionated by SDS-PAGE for identification by liquid chromatography-mass spectrometry (LC-MS). In a second approach, a whole-phage shotgun analysis (WSA) was applied.

Proteomic analysis of cerebrospinal fluid from multiple sclerosis patients.

Multiple sclerosis is an autoimmune inflammatory demyelinating disease of the central nervous system. Disease mechanisms in multiple sclerosis at the molecular level remain poorly understood and no reliable proteinaceous disease markers are available yet. The goal of the present study is the construction of a protein database of two-dimensional gel electrophoresis (2-DE) separated cerebrospinal fluid (CSF) proteins from multiple sclerosis patients.
