  • Patent number: 8288108
    Abstract: A rapid, safe method for predicting sepsis, or a condition similar to sepsis, in a mammal is disclosed, which comprises the following steps: I) isolating RNA from a biological sample of a mammal; ii) labeling the isolated RNA of step I) with a detectable marker; iii) hybridizing the labeled isolated RNA of step ii) with at least one DNA of genes Seq.-ID 1 to Seq.-ID 6705 (Table 1), which is spotted onto a microarray and which is a sepsis-specific gene or gene fragment, under the reaction conditions for hybridizations; iv) quantitatively recording labeling signals of the hybridized RNA of step iii) in an expression profile; v) comparing the expression profile of step iv) with a control sample with respect to a stronger or weaker expression of genes or gene fragments which are specific for sepsis; and vi) combining the expression profile of step v) with protein- and metabolite patterns of the biological sample.

  • Patent number: 7700091
    Abstract: The present invention concerns a TGC method for inducting targeted somatic transgenesis in an animal host, whereby bacteria with a foreign DNA integrated into an episomal vector release, under the control of eukaryotic regulatory elements forulterior transcription and expression, said foreign DNA in the case of infection of a foreign organism, organ, tissue, cell line or individual cells, causing transcription and expression of foreign DNA and/or foreign protein in said location.

  • Patent number: 7115269
    Abstract: The present invention is directed to an attenuated Salmonella comprising a eukaryotic expression vector for delivery of the eukaryotic expression vector to a eukaryotic cell. Delivery may be to eukaryotic cells cultured in vitro or to cells in vivo, such as by oral administration of the attenuated Salmonella comprising the eukaryotic expression vector.

  • Patent number: 6825028
    Abstract: Disclosed is a TGC method for inducting targeted somatic transgenesis in an animal host, whereby bacteria with a foreign DNA integrated into an episomal vector release, under the control of eukaryotic regulatory elements for ulterior transcription and expression, said foreign DNA in the case of infection of a foreign organism, organ, tissue, cell line or individual cells, causing transcription and expression of foreign DNA and/or foreign protein in said location.

  • Publication number: 20030180320
    Abstract: An attenuated strain of Salmonella typhimurium has been used as a vehicle for oral genetic immunization. Eukaryotic expression vectors containing the genes for b-galactosidase, or truncated forms of ActA and listeriolysin—two virulence factors of Listeria monocytogenes—that were controlled by an eukaryotic promoter have been used to transform a S. typhimurium aroA strain. Multiple or even single immunizations with these transformants induced a strong cytotoxic and helper T cell response as well as an excellent antibody response. Multiple immunizations with listeriolysin transformants protected the mice completely against a lethal challenge of L. monocytogenes. Partial protection was already observed with a single dose. ActA appeared not to be a protective antigen.
