Inhibition of PrPSc formation by lentiviral gene transfer of PrP containing dominant negative mutations.
Currently, there is no treatment to cure transmissible spongiform encephalopathies. By taking advantage of the 'prion-resistant' polymorphisms Q171R and E219K that naturally exist in sheep and humans, respectively, we have evaluated a therapeutic approach of lentiviral gene transfer. Here, we show that VSV-G (vesicular stomatitis virus G glycoprotein) pseudotyped FIV-(feline immunodeficiency vi...

the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولIdentifying critical sites of PrPc-PrPSc interaction in prion-infected cells by dominant-negative inhibition
A direct physical interaction of the prion protein isoforms is a key element in prion conversion. Which sites interact first and which parts of PrP(c) are converted subsequently is presently not known in detail. We hypothesized that structural changes induced by PrP(Sc) interaction occur in more than one interface and subsequently propagate within the PrP(C) substrate, like epicenters of struct...
متن کاملSpecies-independent inhibition of abnormal prion protein (PrP) formation by a peptide containing a conserved PrP sequence.
Conversion of the normal protease-sensitive prion protein (PrP) to its abnormal protease-resistant isoform (PrP-res) is a major feature of the pathogenesis associated with transmissible spongiform encephalopathy (TSE) diseases. In previous experiments, PrP conversion was inhibited by a peptide composed of hamster PrP residues 109 to 141, suggesting that this region of the PrP molecule plays a c...
متن کاملGene transfer of dominant negative Rho kinase suppresses neointimal formation after balloon injury in pigs.
Restenosis after angioplasty still remains a major problem for which neointimal formation appears to play an important role. Recent studies in vitro suggested that Rho kinase, a target protein of Rho, is important in various cellular functions. We thus examined whether Rho kinase is involved in the restenotic changes after balloon injury. In vivo gene transfer was performed immediately after ba...
