Viral vectors have been available in various fields such as medical and biological research or gene therapy applications. Targeting vectors pseudotyped with distinct viral envelope proteins that influence cell tropism and transfection efficiency are useful tools not only for examining entry mechanisms or cell tropisms but also for vaccine vector development. Vesicular stomatitis virus (VSV) is ...
To map the regions of the external envelope glycoproteins of human immunodeficiency virus type 1 (HIV-1) involved in the process of membrane fusion, we determined the syncytium-inducing capacity of a panel of transiently expressed chimeric envelope genes. This panel was generated by exchanging gene fragments between four previously studied envelope genes that exhibited a high degree of sequence...
The Cpx two-component signal transduction pathway of Escherichia coli mediates adaptation to envelope protein misfolding. However, there is experimental evidence that at least 50 genes in 34 operons are part of the Cpx regulon and many have functions that are undefined or unrelated to envelope protein maintenance. No comprehensive analysis of the Cpx regulon has been presented to date. In order...
The stratum corneum of the skin serves as an effective barrier for maintenance of the internal milieu against the external environment. At the cell periphery of the stratum corneum is the cell envelope, a highly insoluble membranous structure composed of precursor proteins cross-linked by epsilon-(gamma-glutamyl)lysine bonds. Transglutaminase 1 (TGase 1; keratinocyte TGase), a membrane-bound is...
Nuclear envelope links to inherited disease gave the conundrum of how mutations in near-ubiquitous proteins can yield many distinct pathologies, each focused in different tissues. One conundrum-resolving hypothesis is that tissue-specific partner proteins mediate these pathologies. Such partner proteins may have now been identified with recent proteome studies determining nuclear envelope compo...
BACKGROUND Targeting gene therapy vectors that can home in on desired cell and tissue types in vivo comprise the ultimate gene delivery system. We have previously developed targeting lentiviral vectors by pseudotyping vectors with modified Sindbis virus envelope proteins. The envelope protein contains the Fc-binding region of protein A (ZZ domain), so the virus can be conjugated with antibodies...
The art gene product of the human immunodeficiency virus is required for the expression of virion capsid and envelope gene proteins. The experiments presented here show that sequences located within the coding region of the envelope gene exert a negative effect on the expression of heterologous genes and that the negative effect of these sequences can be relieved by the art gene product. This r...
Whether gene repositioning to the nuclear periphery during differentiation adds another layer of regulation to gene expression remains controversial. Here, we resolve this by manipulating gene positions through targeting the nuclear envelope transmembrane proteins (NETs) that direct their normal repositioning during myogenesis. Combining transcriptomics with high-resolution DamID mapping of nuc...
Performance characteristic of an Unmanned Air Vehicle (UAV) is investigated using a newly developed heuristic approach. Almost all flight phases of any air vehicle can be categorized into trim and maneuvering flights. In this paper, a new envelope called trim-ability envelope, is introduced and sketched within the conventional flight envelope for a small UAV. Optimal maneuverability of the inte...
