The immunohistochemical localization of two myelin specific proteins-basic protein (BP) and proteolipid protein (PLP)-was compared during the process of myelination. Although both proteins were present in oligodendrocytes, (i) neither protein was observed in oligodendrocytes not already closely associated with nerve fibers exhibiting a fluorescent coating; (ii) in any discrete anatomical area o...
The objective of this study is to evaluate the activity of a novel peptide, i.e., bifunctional peptide inhibitor (BPI), which targets the immunological synapse and inhibits autoimmune responses in an antigen-specific manner. Proteolipid protein (PLP)-BPI was designed by conjugating two peptides, an encephalitogenic epitope of proteolipid protein (PLP(139-151)) and an intercellular adhesion mole...
Although proteolipid protein (PLP) and its DM20 isoform are the major membrane proteins of CNS myelin, their absence causes surprisingly few developmental defects. In comparison, missense mutations of the X-linked Plp gene cause severe dysmyelination. Previous studies have established roles for PLP/DM20 in the formation of the intraperiod line and in maintaining axonal integrity. We now show th...
In this report, we describe the isolation and characterization of a full length cDNA clone for rat prolactin-like protein C (PLP-C) and describe the expression of PLP-C mRNA in the developing rat placenta. Nucleotide sequence analysis of the PLP-C cDNA clone predicted a mature protein of 238 amino acids, including a 30-amino acid signal sequence. The predicted PLP-C amino acid sequence contains...
Regulation of blood platelet levels involves an array of cytokines, including the placental hormone PRL-like protein E (PLP-E). The PLP-E receptor is present on megakaryocytes in pregnant mice, nonpregnant female mice, and male mice. Other known megakaryocytic cytokines do not share the PLP-E receptor, and thus the presence of this receptor in nonpregnant animals suggests that PLP-E may be expr...
In this study, the expression of proteolipid protein (PLP) and nestin is studied in the late bell stage of developing rodent teeth in neonatal rats. By using immunohistochemistry, it was shown that odontoblasts, ameloblasts and the stratum intermedium are positive for PLP in regions of active matrix deposition. Reactivity for nestin could be detected in the odontoblasts, stratum intermedium and...
Phantom-limb pain (PLP) is a phenomenon that may appear among people with amputation. Some studies reveal that 70% of people with amputation experience PLP years postamputation. There is a lack of scientific evidence about the cause of PLP. It has been hypothesized that the autonomic nervous system (ANS) could be involved in the mechanism that triggers PLP, but this hypothesis remains unclear. ...
Hydrogen sulfide is a gasotransmitter, with similarities to nitric oxide and carbon monoxide. Although the enzymes indicated below have multiple enzymatic activities, focus here generation of hydrogen sulphide (H2S) characteristics are described accordingly. Cystathionine β-synthase (CBS) cystathionine γ-lyase (CSE) pyridoxal phosphate (PLP)-dependent enzymes. 3-mercaptopyruvate sulfurtransfera...
Many patients with rheumatoid arthritis (RA) have low plasma pyridoxal-phosphate (PLP) but a normal erythrocyte aspartate aminotransferase activity coefficient ( EAST), a measure of vitamin B-6 status in the erythrocytes, compared with healthy subjects. The goal of the present study was to examine the correlations of PLP levels in these two compartments (plasma and erythrocytes) with other esta...
Incubation of rat brain myelin with [3H]palmitic acid in the presence of ATP, CoA and MgCl2 or [14C]-palmitoyl-CoA in a cell-free system resulted in the selective labelling of 'PLP' [proteolipid protein; Folch & Lees (1951) J. Biol. Chem. 191, 807-817] and 'DM-20' [Agrawal, Burton, Fishman, Mitchell & Prensky (1972) J. Neurochem. 19, 2083-2089] which, after polyacrylamide-gel electrophoresis in...
