Of 35 children with the nephrotic syndrome in relapse, 88% were found to have low circulating plasma pyridoxal-5'-phosphate (PLP) levels. Remission of the syndrome was associated with spontaneous normalization of plasma PLP levels in 23 such children. A significant (P less than 0,001) positive correlation (r = 0,81) was found between plasma albumin and PLP levels and a significant (P less than ...
Mutations in the gene for proteolipid protein (PLP) have been associated with CNS dysmyelination and abnormal oligodendrocyte death in spontaneous mouse mutants and in Pelizaeus-Merzbacher disease; however, the effect of mutations on PLP structure and function are little understood. We have identified a monoclonal antibody directed against a novel cell surface epitope of PLP, termed O10. By imm...
BACKGROUND To provide an overview of phantom limb pain (PLP) in China. This includes the prevalence of PLP and possible risk factors. METHODS In a retrospective study, telephone interviews were conducted with 391 amputation patients who underwent extremity amputations at a tertiary hospital in China. RESULTS PLP was found in 29% of the amputees. Pre-amputation pain (OR = 10.4, P = 0.002) an...
L-serine dehydratase (SDH), a member of the beta-family of pyridoxal phosphate-dependent (PLP) enzymes, catalyzes the deamination of L-serine and L-threonine to yield pyruvate or 2-oxobutyrate. The crystal structure of L-serine dehydratase from human liver (hSDH) has been solved at 2.5 A-resolution by molecular replacement. The structure is a homodimer and reveals a fold typical for beta-family...
Abstract Investigation of capability high potential pineapple ( Ananas comosus ) leaves powder (PLP) as reinforcing material on the starch-based foam production has not been reported. This study was aimed to characterize physical and mechanical properties starch formed from mixture cassava PLP. The foams were made using a baking process thermo-pressing machine at temperature 170°C 180°C lower u...
Missense mutations in the human PLP1 gene lead to dysmyelinating diseases with a broad range of clinical severity, ranging from severe Pelizaeus-Merzbacher disease (PMD) to milder spastic paraplegia type 2 (SPG-2). The molecular pathology has been generally attributed to endoplasmic reticulum (ER) retention of misfolded proteolipid protein (PLP) (and its splice isoform DM20) and induction of th...
Myelin is a specialized membrane enriched in glycosphingolipids and cholesterol that contains a limited spectrum of proteins. We investigated the assembly of myelin components by oligodendrocytes and analyzed the role of lipid-protein interactions in this process. Proteolipid protein (PLP), the major myelin protein, was recovered from cultured oligodendrocytes from a low-density CHAPS-insoluble...
BACKGROUND We have demonstrated that pyridoxal 5'-phosphate (PLP), an active form of vitamin B6, inhibits formation of advanced glycation end-products (AGEs) by trapping 3-deoxyglucosone. The present study aimed to clarify if PLP could exert beneficial effects on nephropathy in diabetic rats. METHODS Streptozotocin (STZ)-induced diabetic rats were treated by oral administration of PLP or pyri...
Immunization with myelin components can elicit experimental autoimmune encephalomyelitis (EAE). EAE susceptibility varies between mouse strains, depending on the antigen employed. BL/6 mice are largely resistant to EAE induction with proteolipid protein (PLP), probably a reflection of antigen-specific tolerance. However, the extent and mechanism(s) of tolerance to PLP remain unclear. Here, we i...
Duplications and overexpression of the proteolipid protein (PLP) gene are known to cause the dysmyelinating disorder Pelizaeus-Merzbacher disease (PMD). To understand the cellular response to overexpressed PLP in PMD, we have overexpressed PLP in BHK cells and primary cultures of oligodendrocytes with the Semliki Forest virus expression system. Overexpressed PLP was routed to late endosomes/lys...
