Definitions
- the invention relates to cells infected with bacteria and to their use for producing a pharmaceutical composition, in particular for the treatment of cancer.
- New approaches to treating previously incurable or inadequately curable diseases include the various possibilities of gene therapy and immunotherapy.
- nucleic acid sequence which codes for a desired protein is to be transported into the target tissue by suitable carriers, penetrate into cells there and transduce them to express the desired protein.
- suitable carriers In gene therapy, a nucleic acid sequence which codes for a desired protein is to be transported into the target tissue by suitable carriers, penetrate into cells there and transduce them to express the desired protein.
- Numerous different technological approaches to gene therapy have been developed and tested. Overall, however, the clinical results of this examination of the different approaches as a whole, and particularly in the case of tumor diseases, are rather disappointing. This is mainly due to technical problems.
- the carriers for nucleic acid sequences have a target cell specificity which is too low, the number of cells which can be transduced is too small and the strength and duration of the expression of the desired protein is too low for a therapeutic effect.
- An established form of immunotherapy is immunization with an antigen, the so-called vaccination.
- an antigen After immunization with an antigen, specific antibodies and / or specific cytotoxic lymphocytes are formed in the body which are prophylactic or therapeutic, for example against infectious agents.
- different approaches have been used to treat diseases which have hitherto been inadequately treatable or incurable by vaccination.
- the focus here is on the therapy of tumor diseases by tumor vaccination.
- the aim is to use a tumor vaccine to cause an immune response against the tumor, which leads to the lysis of tumor cells and ultimately to the elimination of the entire tumor tissue. With the different tumor vaccines tested so far, however, no breakthrough in tumor therapy has yet been achieved. A major reason lies in the so-called immune tolerance of the tumor carrier for his tumor.
- dendritic cells In various clinical phases, your tumor vaccination procedures are currently used, which are often based on dendritic cells (summarized in Bancherau et al., Cell, 106: 271-4 (2001)).
- the most common type of immunization with dendritic cells comprises the activation of the cells ex vivo, their loading (“pulsing”) with antigen (for example purified protein, tumor cell extract or defined peptides) and their subsequent application.
- antigen for example purified protein, tumor cell extract or defined peptides
- methods are also used which fuse the In this case, for example, irradiated tumor cells are fused with dendritic cells by suitable methods such as an electric field and then applied (Kugler et al., Nat Med 6: 332-6 (2000)).
- tumors contain a considerable number of leukocytes, in particular lymphocytes (tumor-infiltrating lymphocytes; TIL) and macrophages (tumor-associated macrophages; TAM). It is assumed that the tumor localization of leukocytes is influenced by expression products of the tumor cells, in particular by cytokines, endotheline and also by hypoxia (Sica et al., Int Immunpharmacol, 2: 1045-1054 (2002); Gri shaw et al., Eur J Im unol, 32: 2393-2400 (2002)).
- TIL tumor-infiltrating lymphocytes
- TAM tumor-associated macrophages
- the function of the leukocytes located in the tumor is contradictory. Antitumor (antigen presentation; cytotoxicity; Funada et al., Oncol Rep, 10: 309-313 (20 ⁇ 3); Nakayama et al., AntiCancer Res 22: 4291-4296; Kataki et al., J Lab Clin Med , 140: 320-328 (2002)) as well as an activity which promotes tumor growth (secretion of growth factors; promotion of angiogenesis and metastasis; Leek and Harris J., Mammary Gland Biol Neoplasia, 7: 177-189 (2002); decreased secretion of cytotoxic cytokines such as 11-1 alpha; Il-lbeta; 11-6; TNF alpha; Kataki et al. , J Lab Clin Med, 140: 320-328 (2002)).
- the invention is based on the technical problem of creating means by means of which the target cell localization, in particular door localization, of microorganisms which contain foreign DNA coding for active substances can be improved.
- the invention is based on the finding that macrophages or dendritic 'cells which have been infected with, ie loaded with, bacteria in vitro transport them into the tumor tissue after intravenous administration, that the amount of the bacteria localized in the tumor after iv injection of macrophages loaded with bacteria in vitro was significantly higher than after iv. Injection of a corresponding amount of free bacteria that even infected heterologous tumor cells accumulate in tumors, and that this effect also remains hen consist if infected cells were previously 'inactivated by irradiation.
- the tumor cell line 4T1 (ATCC No. CRL-2539) is derived from a tumor of the mammary gland tissue of BALB / c mice and was applied after infection with attenuated listeria in the described Raf tumor mode 11 (C57BL / 6 background).
- the use of infected cells showed a greatly increased number of bacteria in the tumor tissue, which also previous irradiation of the cells remained.
- Bacteria have a strong adjuvant, in particular due to bacterial components such as lipopolysaccharides (LPS), cell wall components, flagella, bacterial DNA with immunostimulatory CpG motifs, which all interact with different so-called toll-like receptors (TLR) on antigen-presenting cells and can thus stimulate them Effect. It can therefore be expected that infection of cells with bacteria and the administration of these cells not only brings about an improved accumulation of bacteria in the tumor, but that this infection will also result in inflammation and an increase in the systemic and local immune response. As a result, this method can also be used to increase the local immune response as part of immunotherapy.
- LPS lipopolysaccharides
- TLR toll-like receptors
- the invention thus relates to cells of a mammal which are loaded with bacteria and the use of these cells for the prevention or treatment of a disease.
- Cells in the sense of this invention can be, for example, autologous, allogeneic or xenogeneic macrophages, lymphocytes, dendritic cells or tumor cells.
- tumor cells When using tumor cells, they are preferably irradiated or treated with a cytostatic agent in such a way that their ability to divide is blocked.
- cytostatic agent in such a way that their ability to divide is blocked.
- Such cells are preferably isolated from the blood or from tumors using methods known to those skilled in the art.
- autologous, allogeneic or xenogeneic cells established in the culture so-called Zeil lines from normal tissues or from tumors, can also be used.
- Zeil lines from normal tissues or from tumors
- Such cell lines are available, for example, from cell banks such as the American tissue bank (ATCC) in any number and type.
- ATCC American tissue bank
- cells can also be used which have been modified by methods known to the person skilled in the art. Modifications here include in particular genetic ' modifications, but also additional loading of the cells such as B. with peptides, proteins, pharmacological agents or viral particles. Loading in the sense of the invention is the adsorption of bacteria on the cell, the phagocytosis of the bacteria by the cell and / or the infection of the cell.
- Bacteria in the sense of the invention are, for example, gram-negative and gram-positive bacteria, preferably facultatively intracellular bacteria, preferably salmonella or listeria, preferably those bacteria which are capable of division, but which have no pathogenicity for the recipient or are attenuated or killed in their virulence.
- Bacteria attenuated in virulence are characterized, for example, in that at least one gene for a metabolic enzyme is deleted in at least one chromosome of these bacteria or is mutated in such a way that the metabolic enzyme is defective.
- a gene for an enzyme for the synthesis of aromatic amino acids in the chromosome can be deleted, for example the aroA gene which codes for the first enzyme in the biosynthesis of aromatic amino acids, so that these bacteria are dependent on their growth
- aromatic amino acids ii) those proteins which enable the motility of the bacteria to be expressed unimpaired, for example the functionality of the genes iap and actA is retained, and iii) the gene trpS coding for tryptophanyl-tRNA synthetase has been deleted in the chromosome , where plasmids have been introduced into these bacteria, iv) whose replication has been stabilized by a suitable "replication origin", for example by ori pAMßl (Sion and Chopin, 1988), v) which encode the trpS gene for tryptophanyl-tRNA- synthetase, vi) which contain a gene for an endolysin, for example the lysis gene of phage A
- bacteria Due to the loss of at least one gene for an essential metabolic protein, such bacteria have a drastic reduction in their virulence, for example measured in terms of their in vivo reproductive capacity, and nevertheless show a significantly increased bactofection, a lysis of the bacteria in the cytosol, a release of those contained in the bacteria Plasmids and stable expression of the active substance encoded by plasmid.
- Such a bacterial microorganism generally contains a foreign nucleic acid sequence which codes for an active ingredient and is optionally under the control of a regulatory nucleic acid sequence, with either a natural nucleic acid sequence of the bacterium coding for the expression of a bacterial enzyme in the chromosomal DNA of the microorganism is deleted or mutated with the proviso that a translation product resulting therefrom is non-functional and the microorganism does not contain any foreign nucleic acid sequence which codes for the enzyme.
- intracellular bacteria examples include Mycobacterium tuberculosis, M. bovis, M. bovis strain BCG, BCG substrains, M. avium, M. intracellailare, M. africanu, M. kansasii, M. marinum, M. ulcerans, M. avium subspecies paratuberculosis, Nocardia asteroides, other Nocardia species, Legionella pneumophila, other Legionella species Salmonella typhi, S.
- Examples of attenuation of Salmonella are: Inactivating mutations in a pab gene, a pur gene, an aro gene, asd, a dap gene, in nadA, pncB, galE, pi, for, rpsL, ompR, htrA, hemA, cdt, cya , crp, dam, phoP, phoQ, rfc, poxA, galU, metL, metH, mviA, sodC, recA, ssrA, ssrB, sirA, sirB, sirC, inv, hilA, hilC, hilD, rpoE, flgM, tonB or slyA , and combinations thereof.
- the deactivating mutations of the genes listed by way of example for attenuating Salmonella are known to the person skilled in the art.
- the invention further relates to cells which are carriers of bacteria, nucleic acid sequences which code for a protein having been introduced into these bacteria, these proteins preferably being active ingredients for preventing or treating a disease.
- Such proteins can be, for example: antigens of infectious agents such as viruses, bacteria, mycoplasmas, parasites, antigens specific for tumors, in particular Proteins encoded by oncogenes, antibodies, epitope-binding fragments of antibodies and fusion proteins containing at least one epitope-binding fragment of an antibody, directed for example against an antigen 5 on a tumor cell, a lymphocyte such as a T-lymphocyte or an endothelial cell such as a tumor endothelial cell , Enzymes, in particular enzymes for the activation of inactive precursors of a drug, such as a ß-glucuronidase, a
- cytokines such as IL-10, immunostimulating cytokines such as IL-1, IL-2, 11-3 or IL-6, chemokines, interferons, growth factors such as. such as G-CSF, GM-CSF, M-CSF, FGF; VEGF or EGF, or
- genes in the bacteria is regulated by suitable promoters, which come from the 20 bacteria or from viruses or from eukaryotes and can be non-specific, cell-specific or function-specific.
- nucleic acid sequences are added to the gene, which enable transmembrane expression or the secretion of the protein encoded by the gene by the bacterium. Examples of such so-called signal sequences are described in references EP 1042495, EP 30 1015023 and Hess et al. , PNAS USA 93: 1458-1463 (1996).
- the invention furthermore relates to the use of a cell according to the invention for the prevention or treatment of a disease.
- the cells according to the invention are preferably used to treat a tumor disease or an immune disease.
- the gene inserted into the bacteria encodes a protein which i) is tumor cytolytic, ii) has a pro-inflammatory effect, iii) inhibits negative regulating immune cells, for example by inhibiting CTLA-4, B7-H1 or CD25 or TGFß, iv) has an immunosuppressive effect or v) can convert an inactive precursor of a cytotoxic, immunomodulating or immunosuppressive substance into an active substance.
- 100 to 10 9 cells are preferably administered, which are preferably about 0.1 . Per cell . carry (on average) up to 100 bacteria.
- Such cells are administered locally to the skin, into the circulation, into a body cavity, into a tissue, into an organ or orally, rectally or bronchially at least once.
- Diseases in which the cells according to the invention are used represent, for example, tumor diseases, autoimmune diseases, chronic inflammation and organ transplants.

- follow-up studies of the infection were carried out in the control group after iv injection of S. typhimurium aroA 7207. Hie They were made using the same protocol the bacterial count was examined at different times by determining the CFUs.
- 4T1 cells (ATCC CRL-2539) of a tumor line from a breast tumor of BALB / c mice were infected with the attenuated L. monocytogenes strain and an MOI of 10 over a period of 1 h. The cells were then washed and free bacteria were killed by incubation for one hour in the presence of gentyacin. The determination of the CFUs showed that the cells were loaded with 0.15 bacteria per cell. The cell number was adjusted to 5 ⁇ 10 6 cells per ml in PBS. In addition, some of the infected cells were inactivated by radiation.
