摘要:
The invention relates to a microorganism as a carrier of nucleotide sequences coding for antigens and protein toxins comprising the following components: (I) at least one nucleotide sequence coding for at least one complete or partial antigen of at least one wild-type or mutated protein; and (II) at least one nucleotide sequence coding for at least one protein toxin and/or at least one protein toxin subunit; and (III) a) at least one nucleotide sequence coding for at least one transport system which enables the expression of the expression products of component (I) and component (II) on the outer surface of the microorganism and/or enables the secretion of the expression products of component (I) and component (II); and/or coding for at least one signal sequence which enables the secretion of the expression products of component (I) and component (II); and/or (III) b) optionally, at least one nucleotide sequence coding for at least one protein for lysing the microorganism in the cytosol of mammalian cells and for intracellularly releasing plasmids or expression vectors, which are contained in the lysed microorganism; and (IV) at least one nucleotide sequence for at least one activation sequence for the expression of one or more of components (I) to (III), wherein said activation sequence can be activated in the microorganism and/or is tissue cell-specific, tumor cell-specific, macrophage-specific, dendrite-specific, lymphocyte-specific, function-specific or non-cell-specific”; wherein any of components (I) to (IV) can be present either once or several times and either identical or different. Also disclosed are a process of manufacturing thereof, corresponding plasmids or expression vectors and uses of the microorganism as a medicament.
摘要:
It is a general object of this invention to provide a DNA segment comprising a Raf gene in an antisense orientation downstream of a promoter. It is a specific object of this invention to provide a method of inhibiting Raf expression comprising expressing an antisense Raf gene in a cell such that said Raf expression is inhibited. It is a further object of the invention to provide a method of inhibiting Raf kinase activity comprising replacement of a serine or threonine amino acid within the Raf gene for a non-phosphorylated amino acid.
摘要:
The invention relates to a transgenic non-human mammal whose cells express a constitutively active oncogenic mutant of the kinase-domain of the Raf-1 gene or a protein coded by a corresponding normal allele or derivative of the A, B, or c-Raf-1 gene.

摘要:
An antitumor vaccine utilizing oncoproteins as immunogen is disclosed. The oncoprotein could be administered either as isolated, substantially pure product or expressed through a recombinant vaccinia virus containing either the complete coding sequence for the oncoprotein(s) or portions thereof.
摘要:
A Escherichia, Salmonella, Yersinia, Vibrio, Listeria, Shigella, or Pseudomonas bacterium that has the following components: (I) a polynucleotide encoding a heterologous antigenic determinant that induces a CTL response against a tumor cell; (II) a polynucleotide encoding a heterologous protein toxin or toxin subunit; and (III) (a) a polynucleotide encoding a transport system that expresses the products of (I) and (II) on the outer surface of the bacterium or that secretes products of (I) and (II) from the bacterium; and (IV) a polynucleotide that activates the expression of one or more of (I). (II), and/Or (III) in the bacterium wherein polynucleotides (I), (II), (III) and (IV) are different from each other and polynucleotides (I), (II) and (III) encode proteins that are different from each other.
