Definitions
- the present invention relates to Listeria expression vectors which allow expression of the human tumor-associated antigens tyrosinase, Trp-1, MelanA / MART-1 and Trp-2, and to attenuated Listeria bacteria containing these expression vectors, these preferably being bacteria of the strain Listeria monocytogenes. These bacteria can be used for prophylactic, adjuvant or therapeutic immunotherapy, for example for the treatment of malignant melanoma.
- the invention is essentially based on the technical problem of providing means for tumor therapy, in particular for the therapy of malignant melanoma, which do not show the disadvantages of the current therapy methods described above, in particular allow preventive use, as an adjuvant after removal of a Primary tumors are effective or are of therapeutic benefit in the stage of distant etastasis.
- the Listeria expression vectors according to the invention or the recombinant attenuated Listeria bacteria are constructs which are active in gene therapy and which can be used for prophylactic or in the context of adjuvant or therapeutic tumor control, for example in the case of malignant melanoma.
- a tumor-specific immune response can be generated by preferably oral immunization, i.e.
- the body's cellular immune system can be used to target the tumor cells.
- This treatment can also be combined with treatment methods such as chemotherapy or radiotherapy if necessary, but it preferably replaces the latter forms of therapy.
- the present invention is based on the finding that prophylactic or therapeutic treatment of tumors is possible by means of immunization, preferably oral immunization, using the recombinant attenuated listeria according to the invention as a synthesis and transport vehicle for tumor-associated antigens.
- the expression of the individual tumor-associated antigens is preferably carried out as fusion proteins in which, for example, a Listeria-specific signal sequence is fused to the N-terminus of the antigen. After expression, these fusion proteins are exported from the bacterial cells into the environment.
- the bacteria After oral administration, the bacteria pass through the mucosal epithelium of the intestinal tract in the area of Peyer's plaques and are absorbed by the antigen-presenting cells (APCs) of the immune system located there by phagocytosis.
- the Listeria are therefore initially in the phagosome of the infected cell into which they are placed Secretion fusion proteins, which are available for processing to generate HLA class I and HLA class II peptides. Due to the natural infection cycle, both the wild-type Listeria bacterium and defined attested mutants (provided they do not have a deletion of the hly gene) can pass into the cytosol of the cell.
- the fusion proteins secreted in the cytosol are in turn accessible to processing for the generation of HLA class I peptides.
- the peptides generated in both cell compartments are thus available for loading HLA I or HLA class II molecules.
- the peptide-HLA complex is presented on the cell surface of the APCs and a specific T cell response (CD4 + and CD8 + T cells) is induced against the expressed tumor-associated antigens, ie a cellular cytotoxic immune response of the body's immune system against a tumor.
- the tumor cells are specifically identified as degenerate and killed.
- the advantages of this procedure include the fact that the body's own immune system is specifically mobilized in the direction of destruction of the tumor.
- the present invention thus relates to a Listeria expression vector for immunotherapy, the Listeria expression vector comprising the following DNA sequences functionally linked: (a) a promoter active in Listeria; and (b) a DNA sequence coding for human tyrosinase, Trp-1, MelanA / MART-1 or Trp-2 or antigenic epitopes derived therefrom.
- promoter active in Listeria refers to all promoters which allow the expression of tumor-associated antigens in Listeria. These are preferably promoters of Listeria monocytogenes genes, for example constitutive promoters or promoters activated under the conditions of the infection. Promoters which lead to strong expression of the desired antigen are particularly preferred. This term also refers to promoter fragments or promoters with modified sequences that are still biologically active.
- the promoter for the Listeria expression vectors is a promoter of the hly, actA, plcA, plcB or mpl gene, which are each active under the conditions of the infection and which are the Listeria proteins haemolysin, ActA , Encode phosphotidylinositol-specific phospholipase C, phosphatidylcholine-specific phospholipase C or metalloprotease.
- actA / plcB promoter Domann et al. , (1992), EMBO J.
- human tyrosinase, Trp-1, MelanA / MART-1 or Trp-2 encoding DNA sequence refers to any DNA sequence that encodes all or part of the native protein. These DNA sequences and the derived amino acid sequences are described, for example: human tyrosinase gene: Genbank Accession No.: M27160 human trp-1 gene: Genbank Accession No.: AF001295 human trp-2 gene: Genbank Accession No.: D17547 human MelanA / MART -l Gen: Genbank Accession No .: U06452 Please also refer to Figures 1-4.
- Trp-1, Trp-2 and MelanA / MART-l are differentiation antigens of melanocytic origin. Since these antigens are exclusively expressed in melanocytic cells (melanocytes) in the course of melanogenesis, they are extremely well suited to generate a specific immune response against melanoma cells. These differentiation antigens also have the advantage that they are expressed by up to 100% of the cells of a pigmented tumor (melanoma), whereas only approx. 50% of the melanoma cancer testis express antigens such as MAGE-1.
- the enzymes tyrosinase, Trp-1, Trp-2 catalyze the process of pigment formation (malanine biosynthesis). The biosynthesis takes place in the specific organelles, the melanosomes, in the matrix of which the MelanA / MART-1 protein is also located.
- the expression "for human coding DNA sequence” also relates to DNA sequences which encode such forms of human tyrosinase, Trp-1, MelanA / MART-1 or Trp-2, the changes compared to the native form, ie for example Deletions, additions or exchanges of one or more amino acids and / or modified amino acid (s) or the attachment of an ubiquitin residue or modified oligosaccharide side chains, their antigenic properties remaining in whole or in part or in the desired manner, ie they have, for example, the properties described in the examples below with regard to the treatment of a tumor.
- the exchanges preferably include "conservative" exchanges of amino acid residues, ie exchanges for biologically similar residues, for example the substitution of a hydrophobic residue (for example isoleucine, valine, leucine, methionine) for another hydrophobic residue, or the substitution of one polar residue for another polar residue (e.g. arginine against lysine, glutamic acid against aspartic acid etc.).
- the exchanges also include "non-conservative" exchanges, which can maintain or even enhance the antigenic properties of the proteins or individual derived protein fragments (peptides). This can be biological or enzymatic Change the activity of the native protein.
- Deletions can lead to the generation of molecules which are significantly smaller in size, ie which lack amino acids at the N or C terminus, for example.
- the above variants also relate to variants which have a better effectiveness in combating tumors compared to the original form.
- Methods for generating the above changes in the amino acid sequence or corresponding nucleic acid sequence are known to the person skilled in the art and are described in standard works in molecular biology, for example in Sambrook et al. , Molecular Cloning: A Laboratory Manual, 2nd edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor NY (1989).
- a protein or peptide encoded by a nucleic acid sequence modified in this way still has the desired antigenic properties of tyrosinase, Trp-1, MelanA / MART-1 or Trp-2 (in whole or in part). features. These antigenic properties can be determined for the proteins / peptides by stimulating antigen-specific cytotoxic T cell lines. In the case of peptides, it is also advisable to check their HLA binding properties in the context of FACS analyzes.
- the DNA sequences encoding the tyrosinase, Trp-1, MelanA / MART-1, Trp-2 or the above variants should preferably have one transcription termination sequence and one
- L i, steria expression vectors can be constructed according to the invention, inter alia for ligation of the fragments for the promoter and the tumor-associated antigens and insertion into the vector.
- These methods include, for example, in vitro recombination techniques, synthetic methods, and in vivo recombination methods, as described, for example, in Ausubel and Frederick (1991), Current Protocols in Molecular Biology (J.Wiley & Sons, New York) are described.
- Listeria expression vectors in which the DNA sequence coding for human tyrosinase, Trp-1, MelanA / MART-1 or Trp-2 is linked to a DNA sequence coding for a Listeria protein (fragment). that a fusion protein is encoded.
- the portion derived from the Listeria protein preferably represents the N-terminal portion of the fusion protein.
- Various Listeria proteins or fragments thereof are suitable for the production of this fusion protein, for example the genes disclosed above with regard to the Listeria promoters.
- Listeria expression vectors in which the Listeria protein portion of the fusion protein comes from a protein involved in the lysis of the host vacuoles or in the movements of the bacteria in the host cell, preferably Listeriolysin 0 (Lyse), ActA (intracellular movement) or PI-PLC (lysis).
- Listeriolysin 0 Lyse
- ActA intracellular movement
- PI-PLC lysis
- the advantage of listeriolysin 0 to use a Listeria phospholipase or the ActA protein for the construction of fusion proteins is that these proteins are secreted. In the event of infection, these fusion proteins therefore preferentially get into the phagolysosome or cytosol of the infected cell, i.e. into the cell compartments in which the generation of HLA class I and HLA class II presented peptides takes place.
- the fusion proteins can preferably look as follows: a) only the secretory signal sequence of a Listeria-specific protein is fused with
- Protein sequence is fused to the antigen, c) a short fragment of the antigen is added
- the present invention relates to Listeria expression vectors in which the Listeria protein portion of the Fusion protein comprises a signal sequence of a secreted Listeria protein.
- the signal sequence is preferably derived from Listeria hemolysin, a Listeria phospholipase or the ActA protein.
- the starting vector for the production of the Listeria expression vector according to the invention is any vector which leads to expression of the desired antigens in Listeria. This can be an autosomal or stably inserting vector into the Listeria genome.
- the output vector is preferably a "shuttle" vector which can be propagated in another host, for example E. coli. Examples of such vectors are pKSV7 (Frankel et al., 1995, J. Immunol. 155: 4775-4782), pCGU34 (Paglia et al., 1997, Eur. J. Immunol. 27: 1570-1575), pAUL-A ( Niebuhr et al., 1997, EMBO J. 16: 5444-5445) and pLIGAl60.
- the present invention also relates to the Listeria expression vectors according to the invention (autosomal or stably integrated into the genome, for example via homologous recombination) containing recombinant, attenuated Listeria bacteria, preferably Listeria monocytogenes or Listeria innocua, the latter being particularly suitable for enhancing an immune response.
- Listeria bacteria preferably Listeria monocytogenes or Listeria innocua, the latter being particularly suitable for enhancing an immune response.
- the person skilled in the art can select suitable listeria according to the usual criteria with regard to the use of bacteria for vaccination, ie the listeria which can be used for the purposes according to the invention should have immunogenicity, but be sufficiently attenuated to allow safe use in humans. For this it is necessary that the mutant phenotype of the Listeria is absolutely stable, which is usually only possible by creating chromosomal deletions.
- Attenuated mutants include mutants that are deficient in cell-to-cell spread, actA-negative mutants that are deficient in intracellular growth, hly2- (listeriolysin) negative mutants, and mutants that are at least one phospholipase -Gens are deficient (Guz et al., Infect. Immun. 63 (1995), 3665-3673).

- the appropriate dosage and mode of administration preferably oral, intravenous or intraperitoneal administration, will be determined by the attending physician and will depend on various factors including, for example, the age, gender, weight of the patient, stage and severity of the tumor Mode of administration etc.
- the administration must be in an effective amount, ie an amount that the tumor-associated antigen is expressed in an amount that an immune response in T- Cells against the tumor-associated antigen is induced, so that cells containing this antigen are destroyed.
- the medicament according to the invention can either be administered alone or in combination with other tumor therapies.

The expression of the resulting fusion gene is controlled by the plasmid-encoded actA promoter (Domann et al., 1992, EMBO J. 11: 1981-1990; Genbank Accession: X59723). The inserted DNA sequence and its transition points to the vector were sequenced for control.
- the resulting expression vector was called pLIGA-trp2f (encodes the entire trp-2 cDNA) or pLIGA-trp2
- the Listeria expression vectors described in Examples 1 to 4 above were amplified in the E. coli strain XL2-Blue in each case in the L. monocytogenes strain EGD and in the attested mutants ⁇ hly2 and ⁇ actA (Guzmann et al., 1995, Infect Immun. 63: 3665-3573) by electroporation. The technique used for this is well known to the person skilled in the art. Plasmid-bearing listeria were identified from the plasmid-mediated erythromycin resistance.
- the expression of the tumor-associated antigens is then determined using immunological detection methods (eg immunological staining, Western blot) using specific antibodies (MelanA-AK available from Novocastra; Tyrosinase-AK available from BioTrend, Cologne; Trp-1 AK described in Thomsen et al, 1985, J.

Immun. 63: 3665-3573) Electroporation introduced. These bacteria were grown overnight at 37 ° C. in BHI (brain heart infusion) medium (manufacturer: Difco). A 1:50 dilution culture was set up and the growth of the bacteria continued until the middle log phase. The bacteria were harvested by centrifugation at 3000xg. The cells were washed three times with PBS and resuspended in PBS.
- mice As a control, the EGD bacteria carrying the unchanged plasmid pLIGAl60 were also treated and cultivated. Mice from the transgenic strain HLA-A2k b (Vitiello et al., 1991, J. Exp. Med. 173: 1007-1015) were treated with the bacteria resuspended in PBS (EGD-pLIGA-MelanA and EGD-pLIGA160) in the 7-day period Interval immunized. The mice each received oral administration of lxlO 6 bacteria on day 0 and 1X10 7 bacteria on day 7, 14, 21, etc.

- the antigen-specific activity of cytotoxic T cells is considered the basis of an efficient antitumor immune response.
- the spleens from 3 immunized mice are removed 7 days after the last immunization, pooled and mechanically processed so that a single cell suspension is present.
- Spleen cells are transformed into a HLA-A2k b cell line
- Antigen coding gene is stably transfected and can therefore be used
- Stimulation of the cytotoxic activity of antigen-specific T cells can be used. After 5-7 days, the living cells are harvested and checked for their ability to lyse the mentioned antigen-expressing target cells in the 51 Cr release experiment which is well known to the person skilled in the art.
- the MHC class I Melan A restricted lysis of MelanA expressing C1R-A2k b target cells is shown by lymphocytes which were primarily stimulated in vivo with the recombinant L. monocytogenes EGD pLIGA-MelanA vaccine strain. 7 days after the last immunization with EGD-pLIGA-MelanA or EGD-pUGA160 (negative control), the spleen cells were restimulated on day 5 after removal in vitro.
- Tab. 1 Primer for the amplification of the c-DNA sequences coding for antigen.
- the portion of a primer that binds to the complementary sequence of the c-DNA mentioned is underlined
- the interaction of immature DC with bacteria can lead to their maturation and thus have a positive influence on their ability to stimulate T cells.
- the maturation of the DC is accompanied by changes in the expression pattern of specific surface markers, i.e. the expression of specific surface molecules, which are essential for the stimulation of a cellular immune response, is increased.
- specific surface markers i.e. the expression of specific surface molecules, which are essential for the stimulation of a cellular immune response.
- costimulatory molecules such as CD40, CD80, CD86 or adhesion molecules such as CD54.
- the CD83 surface molecule is a specific marker for mature dendritic cells, the function of which is still unclear.
- the expression detection of these surface markers is carried out by means of immunofluorescence in a flow cytometer (FACS).
- the cells were incubated indirectly or indirectly with the following monoclonal antibodies: FITC-conjugated anti-HLA-DR (Becton Dickinson, Heidelberg), anti-CD54 and PE-conjugated anti-CD83 (Coulter-Immunotech, Hamburg), PE-conjugated anti -CD80 (Pharmingen, Hamburg), FITC- conjugated anti-CD40 and FITC-conjugated anti-CD86 (Cymbus Biotechnology, Dianova, Hamburg).
- FITC-conjugated anti-mouse IgG (Dianova, Hamburg) was used as a secondary reagent for anti-CD54 detection.
- Mouse IgG was used as an isotype control.
- the analysis of the expression of the surface markers on the dendritic cells was carried out by means of cytofluorometry (FACScan, Becton Dickinson). The result is shown in FIG. 5. This figure shows that the infection leads to an increased expression of specific costimulatory molecules. Furthermore, the infection leads to a maturation of the DC, which can be seen from the CD83 expression. These data show that infection of the DC with bacterial vaccine vectors has a positive effect on the phenotype of the antigen presenting cells.
