The search to date for accurate protein biomarkers in acute ischemic stroke has taken into consideration the stage and/or the size of infarction, but has not accounted for the site of stroke. In the present study, multiple reaction monitoring using labeled reference peptide (LRP) following laser capture microdissection (LCM) is used to identify site-specific protein biomarker candidates. In mid...

A 23-year-old man with Pelizaeus-Merzbacher disease had a novel mutation, C344A (Thr115Lys), in exon 3 of the proteolipid protein gene (PLP) His mother, heterozygous for the mutation, developed progressive personality change and a gait disorder in her mid-20s. Her MRI at age 53 showed a diffuse severe leukodystrophy. This report extends the phenotypic range of disease due to PLP gene mutations ...

Cyst(e)ine residues of bovine white-matter proteolipid proteins were characterized in a highly purified preparation. From a total of 10.6 cyst(e)ine residues/molecule of protein, as determined by performic acid oxidation, 2.5-3 thiol groups were freely accessible to iodoacetamide, iodoacetic acid and 5,5'-dithiobis-(2-nitrobenzoic acid) (DTNB), when the proteins were solubilized in chloroform/m...

Pelizaeus-Merzbacher disease (PMD) is a dysmyelinating disease resulting from mutations, deletions, or duplications of the proteolipid protein (PLP) gene. Distinguishing features of PMD include pleiotropy and a range of disease severities among patients. Previously, we demonstrated that, when expressed in transfected fibroblasts, many naturally occurring mutant PLP alleles encode proteins that ...

Encephalitogenic T cells invade the brain during neuroinflammation such as multiple sclerosis (MS), inducing damage to myelin sheaths and oligodendrocytes. Only recently, neuronal structures were reported to be a crucial target in the disease. Here, two-photon microscopy using ion-sensitive dyes revealed that within the complex cellular network of living brain tissue, proteolipid protein (PLP)-...

Introduction: Iron deficiency has been known as a contributing factor for restless legs syndrome (RLS). Iron plays a pivotal role in brain physiology as an essential component for proper myelination, as a cofactor for enzymes in neurotransmitter synthesis, lipid and DNA synthesis. Most in vivo studies on RLS have been carried out with fMRI and MR relaxation mapping [1-3]. To date, the associate...

We previously generated a panel of T helper cell 1 (Th1) clones specific for an encephalitogenic peptide of myelin proteolipid protein (PLP) peptide 139-151 (HSLGKWLGHPDKF) that induces experimental autoimmune encephalomyelitis (EAE) upon adoptive transfer. In spite of the differences in their T cell receptor (TCR) gene usage, all these Th1 clones required W144 as the primary and most critical ...

OBJECTIVE Intrathecal IgG synthesis, persistence of bands of oligoclonal IgG, and memory B-cell clonal expansion are well-characterized features of the humoral response in multiple sclerosis (MS). Nevertheless, the target antigen of this response remains enigmatic. METHODS We produced 53 different human IgG1 monoclonal recombinant antibodies (rAbs) by coexpressing paired heavy- and light-chai...

The present study aimed to investigate the effect of exogenous nerve growth factor (NGF) pretreatment on demyelination in the spinal cord of lidocaine‑treated rats, and explored the potential neuroprotective mechanisms of NGF. A total of 36 rats were randomly assigned to three groups (n=12 per group): Sham group; Lido group, received intrathecal injection of lidocaine; NGF group, received intra...
