Project description:Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS); its cause is unknown. To understand the pathogenesis of MS, researchers often use the experimental autoimmune encephalomyelitis (EAE) mouse model. Here, our aim was to build a proteome map of the biological changes that occur during MS at the major onset sites—the brain and the spinal cord. We performed quantitative proteome profiling in five specific brain regions and the spinal cord of EAE and healthy mice with high-resolution mass spectrometry based on tandem mass tags.
Project description:There have been few studies that have focused on the periplaque regions surrounding demyelinated plaques, especially in spinal cords. Areas of incomplete demyelination have been demonstrated but poorly studied. The present study aimed to analyze the molecular immunopathology of periplaque demyelinated lesions (PDLs) in the spinal cord of patients with secondary progressive multiple sclerosis (MS). To achieve this goal, the transcriptomic profiles of PDLs were analyzed in post-mortem tissues derived from the cervical spinal cord of 8 patients with primary or secondary progressive MS. Sixteen spinal cord samples were microdissected for RNA extraction and hybridization on Affymetrix microarrays. Eight periplaque samples (P) were compared to normal appearing white matter (N) from the same patient.

Project description:This project is "Phosphoproteomic analysis of the lumbar spinal cord, a lesion site in the amyotrophic lateral sclerosis (ALS) mouse model SOD1G93A mice". The aim of this study is to clarify the phosphorylation changes by the lumbar spinal cord of SOD1G93A mice at 20w by applying proteomics technology. The goal of this study is to better understand the pathogenesis of ALS. lumbar spinal cord of SOD1G93A mice (n=5) and WT mice (n=4) were collected at 20w, and the phosphoproteomics were compared.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Identification of amyotrophic lateral sclerosis (ALS) associated genes. Post mortem spinal cord grey matter from sporadic and familial ALS patients compared with controls.
Project description:TREM2 signaling in myeloid cells functions as a major pathology-induced immune signaling hub in trauma- and autoimmune-mediated neurodegeneration. Here we compared the influence of TREM2 signaling on single-cell transcriptional profiles of mouse myeloid populations during the pathologies of spinal cord injury (SCI) and multiple sclerosis (MS) models.
