Self-assembled particles of genetically engineered human L subunit ferritin expressing a silver-binding peptide were used as nanocontainers for the synthesis of silver nanoparticles. The inner cavity of the self-assembled protein cage displays a dodecapeptide that is capable of reducing silver ions to metallic silver. This chimeric protein cage when incubated in the presence of silver nitrate e...
Four different vaccine platforms, each targeting the human malaria parasite Plasmodium vivax cell-traversal protein for ookinetes and sporozoites (PvCelTOS), were generated and assessed for protective efficacy. These platforms consisted of a recombinant chimpanzee adenoviral vector 63 (ChAd63) expressing PvCelTOS (Ad), a recombinant modified vaccinia virus Ankara expressing PvCelTOS (MVA), PvCe...
Regulated gene expression will provide important platforms from which gene functions can be investigated and safer means of gene therapy may be developed. Histone deacetylases have recently been shown to play an important role in regulating gene expression. Here we investigated whether a more tightly controlled expression could be achieved by using a novel chimeric repressor that recruits histo...
Mutations within the central region of prion protein (PrP) have been shown to be associated with severe neurotoxic activity similar to that observed with Dpl, a PrP-like protein. To further investigate this neurotoxic effect, we generated lines of transgenic (Tg) mice expressing three different chimeric PrP-Dpl proteins. Chi1 (amino acids 1-57 of Dpl replaced by amino acids 1-125 of PrP) and Ch...
We previously described a functional assay for G protein-coupled receptors (GPCRs) based on stably transformed insect cells and using the promiscuous G protein Galpha16. We now show that, compared with Galpha16, the use of chimeric Galphaq subunits with C-terminal modifications (qi5-HA, qo5-HA, or qz5-HA) significantly enhances the ability of insect cells to redirect Gi-coupled GPCRs into a Gq-...
beta-Galactoside alpha 2,6-sialyltransferase (ST) is a type II integral membrane protein of the Golgi apparatus involved in the sialylation of N-linked glycans. A series of experiments has shown that the 17-residue transmembrane domain of ST is sufficient to confer localization to the Golgi apparatus when transferred to the corresponding region of a cell surface type II integral membrane protei...
We have constructed and expressed recombinant chimeric soluble TGF-β type II receptor fused with the Fc portion of human IgG1 (sTβRII-Fc) in NS0 mouse myeloma cells and isolated cell lines constitutively secreting very high levels of biologically active protein. The GS-NS0 expression system takes advantage of the strong human cytomegalovirus immediate early promoter expression vector and glutam...
Nanobiomaterials such as enveloped virus-like particles with specificity can serve a dual function of vaccination and drug delivery system. Here, we expressed colon carcinoma cell-targeting chimeric virus-like particles (VLPs) made using two capsid proteins, gag and M1 from influenza virus A/swine flu/Iowa/15/30/H1N1 in silkworms. These chimeric VLPs displayed a glycosylphosphatidylinositol-anc...
Human vascular adhesion protein-1 (VAP-1) is a homodimeric 170-kDa sialoglycoprotein that is expressed on the surface of endothelial cells and functions as a semicarbazide-sensitive amine oxidase and as an adhesion molecule. Blockade of VAP-1 has been shown to reduce leukocyte adhesion and transmigration in in vivo and in vitro models, suggesting that VAP-1 is a potential target for anti-inflam...
