The abundant cell surface glycolipid lipophosphoglycan (LPG) was implicated in many steps of the Leishmania infectious cycle by biochemical tests. The presence of other abundant surface or secreted glycoconjugates sharing LPG domains, however, has led to uncertainty about the relative contribution of LPG in vivo. Here we used an Leishmania major lpg1- mutant, which lacks LPG alone and shows att...
Lysylphosphatidylglycerol (LPG) is a basic phospholipid in which L-lysine from lysyl-tRNA is transferred to phosphatidylglycerol (PG). This study examined whether the Staphylococcus aureus mprF gene encodes LPG synthetase. A crude membrane fraction prepared from wild-type S. aureus cells had LPG synthetase activity that depended on PG and lysyl-tRNA, whereas the membrane fraction from an mprF d...
The abundant surface glycolipid, lipophosphoglycan (LPG), of Leishmania promastigotes is composed of phosphosaccharide repeating units linked via a phosphosaccharide core to a conserved lyso alkylphosphatidylinositol membrane anchor. It is shown in this paper that monoclonal antibodies (mAbs) directed against LPG also react with an acid phosphatase secreted by L. mexicana promastigotes. Acid ph...
A key feature of many pathogenic microorganisms is the presence of a dense glycocalyx at their surface, composed of lipid-anchored glycoproteins and non-protein-bound polysaccharides. These surface glycolipids are important virulence factors for bacterial, fungal and protozoan pathogens. The highly complex glycoconjugate lipophosphoglycan (LPG) is one of the dominant surface macromolecules of t...
In this paper, an approach of principal component analysis (PCA) with local pixel grouping (LPG) is used to de-noising the noisy historical document image. This technique ensures the preservation of historic document image local structure. This is due to block matching based LPG which carries out classification to allow only the sample blocks with similar contents used in the calculation for PC...
BACKGROUND/AIMS Lipoprotein glomerulopathy (LPG) is a rare hereditary disease. In this study, we investigated the apoE mutation and the role of double filtration plasmapheresis therapy (DFPP) on a new Chinese patient with LPG. METHODS Renal biopsy was performed on this patient to allow a definitive diagnosis. The mutations in the coding sequence of apoE and the hereditary pedigree of this pat...
Lipoprotein glomerulopathy (LPG) is characterized by the accumulation of lipoprotein thrombi within glomerular capillaries. This rare disorder is associated with various types of mutations in the apolipoprotein E gene (apoE). Herein, we present a case of LPG with a combination of apoE Chicago (Arg147Pro) and apoE (Glu3Lys) mutations. A 51-year-old Japanese woman presented with severe (3+) prote...
At key steps in the infectious cycle pathogens must adhere to target cells, but at other times detachment is required for transmission. During sand fly infections by the protozoan parasite Leishmania major, binding of replicating promastigotes is mediated by galactosyl side chain (scGal) modifications of phosphoglycan repeats of the major surface adhesin, lipophosphoglycan (LPG). Release is med...
In this paper, the effects of temperature on the spectral profiles of long period grating (LPG) fabricated in BGe co doped photosensitive fiber is investigated. The results obtained show that LPG in a B–Ge co doped fiber has negative temperature response or opposite sign of the temperature dependence compared with LPG written in standard telecommunication fiber . Keywords— Fiber grating, Long P...
Lipophosphoglycan (LPG), a surface glycoconjugate of Leishmania promastigotes, has been reported as playing an active role in protecting the parasite within phagolysosomes, by an impairment of monocyte oxidative responses. In this study the effect of LPG on the oxidative burst of human peripheral monocytes, eosinophils and neutrophils was evaluated. Our results demonstrated that either superoxi...
