Abstract: 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.

Abstract: The invention relates to novel pyrido[2,3-b]pyrazine derivatives of the general Formula I, their preparation and use as medicaments, in particular for the treatment of malignant and other disorders based on pathological cell proliferations.

Abstract: 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

Abstract: The invention relates to a nucleid acid coding for at least one partial sequence of a protein kinase of the mitogenic signalling cascade, whereby the partial sequence codes for a binding site for a glycolysis-catalysing enzyme. The invention further relates to a silent mutation of one such nucleic acid or a nucleic acid hybridising with one such nucleic acid or the silent mutation thereof.

Abstract: 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.
