Abstract

The present invention relates in general to the pseudotyping of retroviruses with lymphocytic choriomeningitis virus. In particular, the invention relates to pseudotyping in MLV packaging cells which are optionally env-deleted, or in packaging cells derived from lentiviruses. Preferably, pseudotyping takes place by infection with LCMV or a preferably env-deleted mutant, or by transfection with an expression plasmid containing the gp gene of LCMV or a part thereof and optionally, in addition, the np, l and/or the z gene of LCMV. The invention also relates to the use of such pseudotypes for the infection of cells, particularly the use in gene therapy.

Description

The present invention relates in general to the pseudotyping of retroviruses with lymphocytic choriomeningitis virus. In particular, the invention relates to pseudotyping in MLV packaging cells which are optionally env-deleted, or in packaging cells derived from lentiviruses. Preferably, pseudotyping is carried out by infection with LCMV or a preferably env-deleted mutant, or by transfection with an expression plasmid containing the gp-gene of LCMV or a part thereof and optionally, in addition, the np-, the 1- and/or the z-gene of LCMV. The invention also relates to the use of such pseudotypes for the infection of cells, particularly the use in gene therapy.

Retroviral vectors are increasingly being used in the state of the art, for example, for gene transfer in genetic engineering and medical research or in gene therapy approaches (cf. e.g. C. Baum et al. in Seminars in Oncology: Gene Therapy of Cancer: Translational approaches from preclinical studies to clinical implementations., eds. Gerson & Lattime, Academic Press, 1998). The retroviral vectors are mostly derived from murine leukaemia viruses (MLV) and contain all the sequences of the LTR regions required for integration and the ψ-element responsible for packaging. The regions coding for the virus proteins are replaced by foreign genes and the control sequences thereof which it would be desirable to introduce into human cells. The vectors are expressed in so-called helper cell lines (packaging cell lines) which contain a copy of a complete retrovirus genome. It synthesises all the proteins required for replication and infection, but is unable to package its genomic virus-RNA into particles because it has a defect in the ψ-sequences. If the retroviral vectors are inserted into these helper cells and transcribed, the transgenic mRNA formed is able, by means of the ψ-region which is characteristic of it, to interact with the structure proteins of the helper virus and be packaged to particles. The recombinant virions, which possess no genetic information at all for virus components, adsorb on cells by way of their surface proteins, the capsids are taken up in the cytoplasm, and the transgenic RNA is converted to double-stranded DNA and integrated into the host cell genome. The advantage of this system is the stable integration of the foreign genes which are passed on to the daughter cells on division. The non-specific integration at arbitrary sites of the cell genome, which is characteristic of retroviruses, is a disadvantage.

Retroviral vectors impart a stable colinear integration (i.e. without recombinations and rearrangement of the coding sequences in the vector genome) and thereby a long-term expression of the transgene. Long-term gene expression has otherwise been possible hitherto only by means of the episomal herpes virus vectors or the adeno-associated virus vectors (AAV vectors). The packaging systems (packaging cell lines) have not yet, however, been optimised for the latter vector systems. Moreover, AAV vectors have a lower packaging capacity (about 5 kb for AAV compared with about 10-12 kb for retroviral vectors).

In addition to the gene to be transferred, the transgene, packaging lines also express the vector genome which contains retroviral cis elements. The genomic vector transcript does not, therefore, code for retroviral proteins but is inserted in the packaging lines with the aid of the gag-, pol- and env-gene products into a virion which is infectious but not capable of replication. This virion may then be used as a retroviral vector for transferring the transgene integrated into the vector genome into the desired target cells without further proliferation of the vector occurring there. In other words, the viral vector is only able to infect the target cells but is unable to proliferate any further therein.

The development of retroviral packaging systems is already well advanced and vector supernatants that are free from viruses capable of replication can be produced in large quantities under GMP conditions (Good Manufacturing Practice; Directive of the Commission for laying down principles and guidelines of good manufacturing practice (GMP) for certain medicaments for use in humans (91/356/EEC) of 13.6.91). Vectors based on murine leukaemia virus (MLV vectors) have already been used repeatedly in clinical trials (P. Chu et al., J. Mol. Med. 76 (1998) 184-192).

Two fundamental types of retroviral packaging systems are known in the prior art (J. M. Wilson, Clin. Exp. Immunol. 107 Suppl. 1 (1997) 31-32; C. Baum et al. 1998), loc cit.).

MLV packaging cell lines contain the retroviral genes gag, pol and env ( FIG. 1 ) and the sequences required for packaging the retroviral RNA are deleted (C. Baum et al., (1998), loc. cit.).

The second type of known packaging systems is derived from the lentiviruses (R. Carroll et al., J. Virol. 68 (1994) 6047-6051; P. Corbeau et al., Proc. Natl. Acad. Sci. USA 93 (1996) 14070-14075; L. Naldini et al., Science 272 (1996) 263-267; C. Parolin et al., J. Virol. 68 (1994) 3888-3895; J. Reiser et al., Proc. Natl. Acad. Sci. USA 93 (1996) 15266-15271; J. H. Richardson et al., J. Gen. Virol. 76 (1995) 691-696; T. Shimada et al., J. Clin. Invest. 88 (1991) 1043-1047). Lentiviruses are complex retroviruses which, in addition to the gag, pol and env gene products also express a series of regulatory genes. Examples of lentiviruses from which packaging systems were derived are the human immunodeficiency virus (HIV), the “simian immunodeficiency virus” (SIV) and the “feline immunodeficiency virus” (FIV). The structure of the lentiviral packaging systems is similar, in principle, to that of the MLV vectors.

An advantage of lentiviral vectors is that they are also able to infect resting cells. In the case of MLV vectors, on the other hand, the vector genome can be transported into the cell nucleus only during cell division, i.e. when the nuclear membrane is dissolved. However, in view of the complex structure of the lentiviral genome, packaging systems derived from lentiviruses have disadvantages which are manifested in a comparatively low titre and relatively poor stability. Due to the complex genome structure, cis and trans elements in the genome cannot be separated clearly from one another. In the packaging constructs that express lentiviral gag, pol and env genes there are also to be found, therefore, important cis-regulatory sequences (e.g. parts of the packaging signal) which must also be contained in the vector genome. Due to these homologies, recombinations between vector genome and the packaging constructs may occur and thus the release of retroviruses capable of replication (e.g. an HIV wild virus which would be highly undesirable), so these systems are not comparable with MLV packaging lines.

All the vector systems known hitherto in the prior art also have some crucial shortcomings which prevent successful use in gene therapy: 1. Retroviral vectors are mostly produced only in inadequate titres and cannot be concentrated any further due to the instability of their envelope proteins. 2. Vector particles cannot be purified without loss of infectiousness due to the instability of their envelope proteins. Such purification is essential, however, as the cell culture supernatants from which vectors are harvested are contaminated by cellular constituents. 3. Due to their envelope proteins, retroviral vectors are inactivated by human serum complement. 4. The receptor for the envelope protein of the classic amphotrophic vectors is expressed on virtually all the cell lines considered. However, many primary human cells such as hepatocytes and haematopoietic stem cells which are attractive targets of gene therapy are deficient in functional amphotrophic receptors, as a result of which transduction is rendered difficult or prevented.

The object of the present invention is, therefore, to provide retroviral packaging systems which do not have the disadvantages of the packaging cell lines known in the prior art.

In particular, the object of the present invention is to provide packaging systems which permit a stable retroviral transfer of transgenes into the target cells, i.e. which lead to stable integration of the transgene into the genome of the target or host cells followed by stable expression of this gene.

The object according to the invention is achieved in that retroviruses are pseudotyped with lymphocytic choriomeningitis virus (LCMV).

The present invention relates, therefore, to a recombinant virion which is preferably transfected with one or more foreign genes, which may be obtained by pseudotyping the virus particle with lymphocytic choriomeningitis virus (LCMV).

The tropism and also the stability of a virus is determined primarily by the envelope protein. Murine retroviruses are able to incorporate not only the MLV-env coded glycoproteins but also envelope proteins of other types of virus into their virus coat. As a result, so-called pseudotypes are produced. Retroviral pseudotype vectors are produced by expression of foreign viral envelope proteins in MLV packaging lines. Conventional MLV packaging cell lines contain the retroviral genes gag, pol and env. Sequences which are necessary for the packaging of retroviral genomic RNA were deleted. A vector is introduced into such packaging lines which contains not only the gene which is to be transferred but also the retroviral packaging sequence and other retroviral cis elements (LTR, leader). The retroviral RNA genome is inserted with the aid of the gag, pol and env gene products into a virion which is infectious but not capable of replication. This virion can then be used as a retroviral vector for the transduction of cells. Pseudotype packaging lines also contain the envelope protein gene of a foreign virus. The pseudotype packaging lines according to the invention contain the envelope protein gene of LCMV, and expression of the LCMV glycoproteins takes place.

The present invention provides for the first time vector systems which may be produced in high titres and concentrated. The vector particles according to the invention can also be purified without or without any substantial loss of infectiousness. Surprisingly, it has become apparent within the scope of the present invention that the pseudotyping according to the invention is not cytotoxic for the packaging cells. Stable packaging cell lines (packaging systems) are thus provided for the first time which permit a stable retroviral transfer of transgenes into the target cells, i.e. which lead to a stable integration of the transgene into the genome of the target or host cells followed by stable expression of this gene.

The cell lines according to the invention are also characterised by a broad, trans-species host cell spectrum (cell tropism). A crucial advantage of the present invention is the fact that individual mutations in the envelope protein of LCMV can lead to a modification of the tropism of LCMV. That is, due to individual point mutations in gp, viruses that are more likely to infect nerve cells become viruses that are more likely to infect lymphocytes or those that are more likely to infect monocytes.

Within the scope of the present invention, LCMV is used for pseudotyping. It is possible or it may even be preferable to use other strains of LCMV instead of the LCMV wild-type. Slight variations in the gp nucleic acid sequence or in the amino acid sequence of the expressed envelope protein in various strains of LCMV may thus alter substantially the cell tropism (host cell spectrum) of LCMV (M. Matloubian et al., J. Virol. 67 (1993) 7340-7349; M. N. Teng, J. Virol. 70 (1996) 8438-8443; King et al., J. Virol 64; 1990, 5611-5616). No such tropism variants in the glycoprotein are found for any of the other retroviral vector systems known hitherto, and a more targeted transduction of the desired cell type is made possible for the first time according to the invention. According to a preferred embodiment of the invention, it may therefore be advantageous to provide packaging systems with various glycoprotein variants (GP variants) for different applications.

Within the scope of the present invention, the starting material is the gp genes of the neurotropic LCMV strain Armstrong, L(ARM) (L. Villarete et al., J. Virol. 68 (1994) 7490-7496) (region coding for SEQ ID NO: 4; compare appendix to the sequence protocol, re SEQ ID NO: 3), and of the haematotropic strain WE (V. Romanowski et al., Virus Res. 3, (1985) 101-114) (SEQ ID NO: 1). Also included according to the invention are variants (tropism variants) of these two strains in which individual amino acids are exchanged in the gp gene product, since the tropism of the virus can thereby be altered.

It is rather probable that “cryptic splice regions” are located in the RNA sequence, since LCMV is an RNA virus without a nuclear phase during the propagation cycle. The removal of such regions (correction for aberrant splicing) can be utilised to achieve an improved expression. Such “splice-corrected” variants are also, therefore, included according to the invention. Pseudotyping can be improved by such optimisation of GP expression, whereby it is possible to dispense with an additional support by means of at least one further LCMV protein.

A preferred variant is the mutant WE-HPI, which has been developed according to the present invention, which nucleic acid gp coding for GP (Open Reading Frame (ORF) shown in SEQ ID No. 25) contains mutations at positions 281, 329, 385, 397, 463, 521, 543, 631, 793, 1039, 1363 and 1370 as compared to the LCMV strain WE, which encodes the GP variant shown in SEQ ID NO. 26, the latter of which shows amino acid replacements at positions 94, 110, 129, 133, 155, 174, 181, 211, 265, 347, 455 and 457 as compared to SEQ ID NO. 2. This GP variant has the advantage that it is stable even without additional LCMV aiding proteins and, compared to strain WE, achieves an improved pseudotyping.

The invention therefore further relates to a variant of the lymphocytic choriomeningitis virus, containing the gene gp, which encodes the sequence shown in SEQ ID NO. 26 or a part thereof, wherein the gp gene preferably has the sequence shown in SEQ ID NO. 25 or a part thereof. Further included according to the invention is a protein having the amino acid sequence shown in SEQ ID NO. 26 or a part thereof, as well as a nucleic acid encoding this protein, preferably the sequence shown in SEQ ID NO. 25 or a part thereof. This virus variant as well as the nucleic acid sequences and amino acid sequences last mentioned, are obtainable, for example starting from the LCMV variant WE by methods generally known to the skilled person (for example by introducing point mutations).

Generally speaking, expression vectors which permit a high, stable gene expression in eukaryotic cells are suitable for the expression of LCMV. The choice of expression vector is, however, crucial for the packaging of the retroviral LCMV pseudotypes only insofar as it must guarantee a high and stable level of expression, i.e. a level of expression which is high enough to permit the formation of pseudotypes and which is durable (stable) without switching off of the promoter occurring.

The following two expression cassettes are particularly preferred according to the invention:

(CMV promoter)—(β-globin-intron-2)—(gp)—(SV40 poly A-signal)

and

(EF-lalpha promoter)—(gp)—(poly-A signal of the G-CSF gene)

(S. Mizushima, Nucleic Acids Res. 18 (1990) 5322, T. Uetsuki, J. Biol. Chem. 264 (1989) 5791-5798).

The sequences for the constituents of the expression cassettes are shown in the sequence protocol or are generally well known:

cytomegalovirus promoter (CMV promoter):

(M. Boshart et al., Cell 41 (1958) 521-530; F. Langle-Rouault et al., Virol. 72 (7) 6181-5 (1998))

betaglobin-intron-2:

(Jeffreys, A. J. et al., Cell 12 (1977) 1097-1108)

SV40 poly A signal:

(M. Boshart et al., Cell 41 (1958) 521-530; F. Langle-Rouault et al., Virol. 72 (7) 6181-5 (1998))

EF-lalpha promoter: SEQ ID NO: 9

(S. Mizushima, Nucleic Acids Res. 18 (1990) 5322, T. Uetsuki, J. Biol. Chem. 264 (1989) 5791-5798).

G-CSF poly A signal:

(S. Mizushima, Nucleic Acids Res. 18 (1990) 5322, T. Uetsuki, J. Biol. Chem. 264 (1989) 5791-5798).

gp (LCMV):

compare SEQ ID NO: 1, 3, region coding for SEQ ID NO: 4 (see also Appendix to the sequence listing).

Within the scope of the present invention, the above-mentioned expression cassettes are also therefore included, changes in the relevant nucleic acid sequences being possible as long as the functionality of the expression cassettes remains intact, i.e. their use according to the invention permits pseudotyping of the packaging cells and also does not prevent the transfection of the target cells and the stable integration of the transgenes into the host genome.

Moreover, an episomal EBV expression vector (Epstein-Barr-Virus; cf. F. Langle-Rouault et al., Virol. 72 (7) 6181-5 (1998)) (pCep4) from Invitrogen also exhibits high expression and is therefore preferred within the scope of the present invention.

The present invention also provides, therefore, a packaging cell which contains the retroviral genes gag (region coding for SEQ ID NO: 12; cf. Appendix to the sequence listing, re SEQ ID NO: 11), pol (region coding for SEQ ID NO: 13; cf. Appendix to the sequence listing, re SEQ ID NO: 11) and optionally the retroviral gene env (region coding for SEQ ID NO: 14; cf. Appendix to the sequence listing, re SEQ ID NO: 11) and/or regulatory retroviral genes (in the case of lentiviral packaging systems, see below, e.g. the gene coding for the lentiviral Rev protein which prevents splicing of the retroviral genomic RNA) and also contains the gene gp coding for the glycoproteins GP-1 and GP-2 of LCMV (region coding for SEQ ID NO: 4; cf. Appendix to the sequence listing, re SEQ ID NO: 3) or a part thereof. Also included are nucleic acid sequences which exhibit modifications or deviations (mutations, deletions etc.) in the sequences as long as, when used according to the invention, the pseudotyping of the packaging cells is guaranteed and the transfection of the target cells and the stable integration of the transgenes into the host geriome is not impeded. This includes fragments of the named sequences. These derivatives should always be included hereinafter when any gene as such is mentioned.

Within the scope of the present invention, “GP” or “GP protein” denotes the GP-C precursor protein from which GP-1 and GP-2 are then produced by proteolytic cleavage, these being denoted hereinafter simply “LCMV glycoprotein”.

According to the invention, moreover, pseudotype packaging systems are provided in which, apart from the gp gene product (SEQ ID NO: 4), one or more other genes of LCMV are expressed such as, for example, the gene np coding for the nucleoprotein (region coding for SEQ ID NO: 5; cf. Appendix to the sequence listing, re SEQ ID NO: 3), the gene z coding for a protein with an unknown function (region coding for SEQ ID NO: 8; cf. Appendix to the sequence listing, re SEQ ID NO: 6) and the gene l coding for RNA polymerase (region coding for SEQ ID NO: 7; cf. Appendix to the sequence listing, re SEQ ID NO: 6). According to a particular embodiment of the invention, these genes may stem either from the WE or Armstrong strain of LCMV. In this connection, either the complete sequences of the genes np, z and/or l (SEQ ID NOs: see above) or parts thereof may be used. Sequences included according to the invention are nucleic acid sequences which exhibit modifications or deviations (mutations, deletions etc.) in the sequences (derivatives), as long as pseudotyping of the packaging cells is guaranteed and the transfection of the target cells and the stable integration of the transgenes into the host genome is not impeded. This includes fragments of the named sequences. These derivatives should always be included hereinafter when any gene as such is mentioned.

The invention also provides, therefore, a packaging cell which, in addition to the gp gene of LCMV, contains at least one gene from the group comprising the gene np coding for the nucleoprotein, the gene l coding for RNA polymerase and the gene z of LCMV coding for a protein of unknown function.

The MLV/LCMV pseudotypes, i.e. recombinant retroviral virions which contain the LCMV glycoprotein incorporated in their coat, are produced by the packaging cells according to the invention.

For the production of the recombinant virions, the starting materials for the viral packaging cell lines within the scope of the present invention are preferably all the cell lines that produce high titres of retroviral vectors. Cell lines used in preference are NIH3T3, Te671, 293T, HT1080 (F. L. Cosset et al., J. Virol. 69 (1995) 7430-7436; D. Markowitz et al., Virology 167 (1988) 400-406); W. S. Pear et al., PNAS 90 (1993) 8392-8396). The choice of cell line is not important, however, for the specific advantages of the invention because it has become apparent that GP does not have a toxic effect in any cell line examined hitherto. If, therefore, lines should be found in the future which permit a more efficient vector production (i.e. more stable titre which is at least as high as in the above-mentioned lines, >10 6 /ml), these may also be used.

The gag and pol genes of the Moloney strain of murine leukaemia viruses (MOMLV) are expressed in the packaging systems used in preference for pseudotyping according to the invention (gag: region coding for SEQ ID NO: 12, pol: SEQ ID NO: 11, Nukleotide 1970-5573; cf. Appendix to the sequence listing, re SEQ ID NO: 11). According to the invention, however, other gag and pol variants of MLV are also included as long as they exhibit the above-mentioned advantages for vector production. In particular, the above-mentioned gene derivatives are included according to the invention.

It was ascertained within the scope of the present invention that LCMV-GP also pseudotypes lentiviral nucleocapsids (see examples). According to a particular embodiment, the packaging systems may also therefore contain the gag and pol gene products of lentiviruses, i.e. lentiviral packaging systems (packaging cell lines) may be used. It is immaterial from which lentivirus the packaging system is derived. Suitable lentiviral packaging cells within the scope of the present invention include, for example, cell lines derived from human immunodeficiency virus (HIV), simian immunodeficiency virus (SIV) or feline immunodeficiency virus (FIV). In this connection, it could be necessary for an efficient production of infectious lentivirus vectors to express, in addition, accessory lentiviral genes such as rev (region coding for SEQ ID NO: 21; cf. Appendix to the sequence listing, re SEQ ID NO: 15) or tat (region coding for SEQ ID NO: 20; cf. Appendix to the sequence listing, re SEQ ID NO: 15) in the case of HIV vectors. Within the scope of the present invention, LCMV proteins may be used for pseudotyping in all the lentiviral packaging systems.

The present invention also provides a (viral) packaging cell or a pseudotyped virion in which the virus is selected from the family of retroviridiae, particularly the MLV-related viruses and the lentiviruses. According to a particular embodiment of the invention, the retroviral packaging cell is selected from the group comprising packaging cells derived from MLV, HIV, SIV and FIV.

According to the invention, moreover, a pseudotyped virion is provided which can be obtained by pseudotyping a retroviral cell of MLV which does not express an ENV protein, the defective mutant L(ARM) of LCMV being used for pseudotyping. Alternatively, other variants of LCMV may also be used.

The present invention also provides a process for the production of the packaging cells/packaging cell lines according to the invention, wherein a retroviral packaging cell line transfected with one or more foreign genes is infected with LCMV according to known methods (cf. e.g. Maniatis, Sambrook, Fritsch: Molecular cloning, a laboratory manual; Cold Spring Harbor Laboratory Press, 1982). The virions which contain LCMV glycoprotein incorporated in their coat are expressed by the packaging lines. According to a particular embodiment of the invention, the pseudotype-producing packaging cells may be produced by transfecting a retroviral packaging cell line transfected with one or more foreign genes with an expression plasmid which contains the gp gene of LCMV or a part thereof and optionally, in addition, one or more genes from the group comprising np, l and z of LCMV.

The present invention also relates, therefore, to a process for the production of retroviral pseudotype vectors wherein retroviral packaging cells containing at least the gp gene of LCMV or a part thereof (see above) are produced initially and these are then cultivated under conditions that are suitable for the production of virions.

Within the scope of the present invention, the retroviral packaging cell line used is preferably an MLV packaging cell line which does not express a functional ENV protein and the LCMV used for pseudotyping is the deleted mutant L(ARM). The cell line described by von Laer et al. (J. Virol. 72 (1998) 1424-1430) may also be used as the ENV-negative packaging cell line.

The virions or packaging cells lines according to the invention may be used advantageously for producing viral pseudotype vectors which may be used advantageously for the transduction of cell lines but also of primary eukaryotic cells for research purposes (in vitro) or within the context of gene therapy.

The use of virions/packaging cells for gene therapy also comes into consideration, however, within the scope of the present invention. In this connection, gene therapy may include the treatment of infectious diseases (such as HIV infections or AIDS) and neoplasms (such as breast cancer/mamma carcinoma) or melanoma and other diseases accessible by gene therapy. The transduction of haematopoietic stem cells also comes into consideration within the scope of the present invention.

The recombinant virion or the recombinant packaging cell (cell line) of the present invention comprises one or more transgenes. Preferably, said transgenes are selected from the group comprising marker genes such as, e.g. neo, lacZ or enhanced green fluorescent protein (EGFP) and/or genes which may be used therapeutically, such as, e.g. the suicide gene herpes simplex virus thymidine kinase (HSV-tk), cytosine deaminase (CD) and sequences with an antiviral effect such as ribozymes, antisense sequences and transdominant-negative genes and genes that may be used in tumour therapy such as mdr-1 for the protection of haematopoietic cells in chemotherapy, and cytokine genes. Moreover, all transgenes which could be of interest within the context of a targeted gene transfer and the expression of the transgene(s) in cells in vitro or within the context of gene therapy may, however, be used.

The invention also includes a process for the preparation of a pharmaceutical preparation for gene therapy wherein viral pseudotype vectors or retroviral packaging cells according to the invention are formulated optionally with pharmaceutically compatible excipients and/or carriers. The present invention also provides a pharmaceutical preparation for gene therapy which comprises retroviral packaging cells according to the invention and optionally pharmaceutically compatible excipients and/or carriers.

It is often essential for gene therapy in vivo that only specific target cells are genetically altered, but not other cells. For example, a suicide gene shall enter tumor cells only but not healthy cells, a chemotherapy resistance gene shall enter healthy blood stem cells but not contaminating tumor cells. For the more targeted gene transfer into specific cells it has been tried already to incorporate ligands into the coat of retroviral vectors or into liposomes. A targeted gene transfer, however, was not possible so far by utilizing these methods since the ligands only mediate the binding to the target cell but not the entry of the vector genome into the cytoplasm (F. L. Cosset et al., J. Virol. 69 (1995) 6314-6322), i.e. no fusion with the membrane of lysosomes occurs. This problem can be solved by using viral coat or envelope proteins having fusion activity, i.e. proteins which surmout the lysosomal membrane as fusion proteins. The use of LCMV GP is a considerable advantage in this context, since this viral envelope protein undergoes a conformational change at low pH, as it predominates in the endosome of the target cell. The conformational change leads to the activation of the fusion function, even without the requirement of receptor binding of the LCMV GP. Since LCMV GP—in contrast to other fusion proteins—does not mediate fusion of cell membranes, it is not cytotoxic and does not lead to formation of giant cells (cf. C. di Simone et al., Virology 198 (1994) 455-465).

According to the present invention, retroviral packaging cells are included, which contain the retroviral genes gag, pol and env and/or regulatory retroviral genes and further the gene gp coding for the glycoproteins GP-1 and GP-2 of LCMV or a part thereof, wherein env is modified in that it encodes an Env protein, which mediates a specific binding to the target cell (so-called targeting-env) and wherein gp is a variant, which encodes a GP protein having fusion activity (so-called fusion helper). Further enclosed are methods for the preparation of these packaging cells, in which a packaging cell is used as retroviral packaging cell, which contains the retroviral gene env, which is modified in that it encodes an Env protein, which mediates a specific binding to the target cell and wherein gp is a variant, which encodes a GP protein having fusion activity. In this context it might be necessary to mutate the part of the sequence encoding the receptor binding site of LCMV GP (without impairing the fusion activity) in order to prevent or reduce binding of GP to its cellular receptor. Alternatively, the use of neutralizing antibodies against GP is to be considered, which are able to neutralize the receptor binding without inhibiting the pH-dependent fusion by GP. Due to the fact that according to the present invention, for the first time stable packaging cell lines are provided, it is now possible to identify the receptor binding site by targeted mutagenesis of GP-1. This method as well as the isolation of the mentioned neutralizing antibodies are well-known to the skilled person.

The present invention provides for the first time vector systems which may be produced in high titres and concentrated. The vector particles according to the invention may also be purified without or without any substantial loss of infectiousness. The cell lines according to the invention are also characterised by a broad, trans-species host cell spectrum (cell tropism). Surprisingly, it has become apparent within the scope of the present invention that the pseudotyping according to the invention is not cytotoxic for the packaging cells. Stable packaging cell lines (packaging systems) are thus provided for the first time which permit stable retroviral transfer of transgenes into the target cells, i.e. which lead to a stable integration of the transgene in the genome of the target or host cells followed by stable expression of this gene.

The present invention will be explained below on the basis of examples, figures and a sequence listing.

Karasuyama et al., Eur. J. Immunol 18 (1988) 97-104). The human precursor cell line K562 was kept in RPMI (Gibco) which had been enriched with 10% FCS.

LCMV was deposited on 10.11.1998 at the European Collection of Cell Cultures (ECACC), Salisbury, Wiltshire SP4 OJG, Great Britain under the access number V98111005 according to the Budapest Treaty.

The MESV-type retroviral vector which carries the neomycin phosphotransferase gene (MPLN) has already been described (H.-G. Eckert, Blood 88 (1996) 3407-3415). The amphotrophic helper was a recombinant Moloney MLV capable of replication in which parts of the pol and the majority of the env gene had been replaced with that of the MLV strain 4070A [Mo-Ampho-MP, R320 (C. Munk, Proc. Natl. Acad. Sci. USA 94 (1997) 5837-5842)] as a SailI to ClaI fragment. The virus was propagated in Sc-1. The plaque-purified WE strain of the LCM virus was propagated in L-929 cells (T. M. Rivers, Virology 26 (1965) 270-282).

Continuous Flow Cytometric Analysis of LCMV-GP Expression

In order to analyse the expression of the LCMV glycoprotein, 3×10 5 to 10 6 cells were harvested, pelleted and resuspended in 50 μl of a 1:40 dilution of mouse ascites which contained a murine monoclonal antibody against LCMV GP-1 (M. Bruns et al., Virology 130 (1983) 247-251). After 20 minutes' incubation on ice, the cells were washed three times with phosphate-buffered saline (PBS) and then incubated for a further 20 minutes in a 1:80 dilution of an FITC labelled goat anti-mouse antibody (Dako, Glostrup, Denmark). After three final wash stages in PBS, the cells were analysed using an FACScalibur device (Becton Dickinson, Heidelberg).

Titration of the Viruses

In order to determine the vector titre, 5×10 4 Sc-1 cells were inoculated with a five-fold dilution of the supernatants in 24-well tissue culture plates. For the retroviral neovector the selection was initiated after 24 hours with 400 μg G418 per ml (dry weight GIBCO). The medium was replaced every four days. The colonies were evaluated after ten days. The titre was expressed as G418 resistance transfer units per ml (GTU/ml). For the retroviral MFGnlsLacZ vector, X-gal (5-bromo-4-chloro-3-indolyl-β-D-galactopyranoside) staining was carried out two days after inoculation as described earlier (G. R. McGregor, Methods Mol. Biol. 7 (1989) 1-19). The titre was expressed in LacZ transfer units (LTU) per ml. Plaque-forming units of LCMV were assayed on L-929 cells as described previously (F. Lehmann-Grube, J. Gen. Virol. 37 (1977) 85-92).

MLV (LCMV) pseudotypes were neutralised by preincubation of an equal volume of a virus-positive supernatant with an anti-LCMV gp44-neutralising monoclonal antibody which was diluted 1:100 (M. Bruns et al., Virology 130 (1983) 247-251). The titres were then determined in LTU per ml as described.

DNA Analysis

The production of DNA and Southern blot analysis were carried out as described earlier (C. Stocking et al., Cell 53 (1988) 869-879). The genomic DNA was digested with HINDIII which makes a single cut at the 3′ end of the neo gene in the MP1N vector. A fragment which contains the complete neo gene was used as a probe.

Production and Purification of the Virus

The virions were purified by gradient ultracentrifugation as described in detail earlier (L. Martinez-Peralta et al., J. Gen. Virol. 55 (1981) 475-479). In short, infectious cell culture supernatants were purified by centrifugation at low and high speeds. The virus was pelleted by ultracentrifugation and then purified in a 0-40% Urografin gradient (Schering AG, Berlin, Germany).

Example 1

Infection of TeLCeb with LCMV-LacZ Gene Transfer to Target Cells with Neutralisation of the Vector by Anti-GP Mab and Concentration of the Vector in the Gradient

Rescue of an envelope protein-negative murine leukaemia virus vector with lymphocytic choriomeningitis virus: In order to find out whether LCMV is able to rescue (mobilise, complete) an envelope protein-negative retroviral vector, the env-negative packaging cell line TELCeB was infected with the LCMV WE strain in an m.o.i. of 0.01 (m.o.i.: multiplicity of infection; denotes the number of virus particles with which a cell is infected). TELCeB stem from the human fibroblast cell line Te671 and contain gag and pol genes as well as the retroviral vector MFGnlsLacZ (G. M. Crooks et al., Blood 82 (1993) 3290-3297). After infection with LCMV, the titre of LacZ transferring units (LTU) and of LCMV wild-type virus was measured by X-gal staining of the mouse fibroblast target cells (Sc-1 ) and by a plaque test (in plaque-forming units, PFU). In addition, the expression of LCMV glycoproteins in the infected TELCeB was measured by continuous flow cytometric analysis. The results are shown in FIG. 6 . LTU were prepared for six days with a maximum of 5×10 4 LTU per ml on day 3. The highest titre for LCMV wild-type virus was 3×10 8 on day 2. The production of PFU had already decreased on day 3 when the maximum production of LTU together with the highest expression of LCMV glycoprotein was to be seen. The reason for this discrepancy could lie in the production of defective interfering LCMV particles which inhibit the replication of LCMV wild-type, but in all probability not the release of infectious retroviral vector particles. No obvious cytopathic effect was to be observed during the replication of LCMV in the packaging cell lines, although high levels of LCMV glycoproteins were expressed (data not shown).

A test was then carried out to find out whether the infectious virus which was produced by the LCMV-infected TELCeB mediated the LacZ gene transfer specifically by way of LCMV glycoproteins. The supernatants were incubated for one hour with a neutralising anti-LCMV gp44 monoclonal antibody. This led to a more than threefold log reduction of the LTU titre. The amphotrophic pseudotype of the same retroviral vector was not neutralised by the anti-LCMV antibody (Tab. 1). These data show that the MLV/LCMV chimeric virions actually carried LCMV glycoproteins on their surface which are able to mediate gene transfer in the absence of retroviral envelope proteins by means of the LCMV receptor.

Tab. 1: Infectious retroviral vector particles which are produced by LCMV-infected packaging cell lines can be neutralised by anti-LCMV glycoprotein monoclonal antibodies (mab).

	Virus	anti-LCMV mab	Titre (LTU/ml)

	Amphotrophic helper	yes	2 · 10 5
	LCMV	no	7 · 10 4
	LCMV	yes	3 · 10 1

MLV (LCMV) pseudotypes retain infectiousness during concentration by gradient ultracentrifugation: amphotrophic retroviruses lose infectiousness after centrifugation, in all probability due to the lability of the retroviral envelope glycoproteins (V. Moenning et al., Virology 61 (1974) 100-111). A test was carried out to find out whether the MLV(LCMV) pseudotypes are more stable. TELCeB were infected with LCMV or with amphotrophic helper virus. Titres of the viral vector in the direct supernatant were 5×10 4 LTU per ml for both pseudotypes. Viruses were pelleted from 60 ml supernatant and purified by centrifugation through a 0-40% Urografin gradient. The pseudotype titres (in LTU per ml) are shown in FIG. 7 . The total expected yield of 3×10 6 LTU for the LCMV pseudotype was obtained in full, in contrast to 1×10 3 LTU for the amphotrophic virus. The reverse transcriptase activity in the bands showed that the amount of virus particles which was obtained from the gradient was similar for both pseudotypes (data not shown). Compared with the amphotrophic virions, the infectiousness of MLV(LCMV) pseudotypes during ultracentrifugation was, however, more stable at least by a factor of 1000.

LCMV pseudotypes were also stable during storage at 4° C. Within the period of observation of three days, the loss of titre was twice as low (compared with the starting titre of MLV (LCMV)). A deep freeze cycle (−80° C.) and thawing led to a loss of pseudotype titre, which was twice as low.

Example 2

Gag and Pol Gene Products are Required for Packaging Retroviral RNA into the LCMV Glycoprotein Pseudotypes

A test was carried out to find out whether the retroviral RNA alone could be packaged into the LCMV or whether gag and pol gene products were required. 293 cells and 293gp2 cells, the latter containing gag and pol of MLV, were transfected with a retroviral vector based on MLV which contained the neo gene (MP1N), and cell lines which contained the stably integrated vector were prepared by G418 selection (293MP1N and 293gp2MP1N; a clone of the cell line 293gp2MP1N denoted SF23 was deposited at the Deutsche Sammlung von Mikroorganismen und Zellkulturen (German Collection of Microorganisms and Cell Cultures; DSMZ), Mascheroder Weg 1b, 38124 Braunschweig, Germany under the access number DSM ACC2374 according to the Budapest Treaty). These cells (mass cultures) were then infected either with an amphotrophic helper capable of replication or with the LCMV wild-type virus. The results are shown in Tab. 2. Infectious vector which transferred neomycin resistance was obtained from both cell lines after infection with the amphotrophic helper. After infection with LCMV, however, only 293gpMP1N produced infectious retroviral particles whereas 293MP1N, which expressed no retroviral Gag or Pol, did not. Retroviral genomic RNA was not, therefore, packaged into infectious virions by LCMV in the absence of gag and pol gene products.

Example 3

Infection of 293gpMP1N with LCMV and Stable Gene Transfer to L929—Detection by Southern Blotting

MLV (LCMV) pseudotypes mediate transfer and stable integration of the retroviral vector genome: the transfer of G418 resistance by the retroviral LCMV pseudotype showed that the marker gene had been stably integrated into the host genome. In order to verify that MLV (LCMV) pseudotypes are able to mediate stable transduction with integration of the transgene into the target cell genome, a retroviral vector which contained the neomycin resistance gene (neo) was rescued by LCMV infection of the env-negative packaging cell line 293gp2MP1N. The titres were measured by transfer of G418 resistance to Sc-1 cells and lay between 1×10 3 and 1×10 4 G418 transfer units (GTU) per ml. Resistant cell clones appeared after eight days'selection and were cultivated for a further three weeks. The DNA of 12 G418-resistant clones underwent a Southern blot analysis after restriction with HindIII, a single-cut enzyme, using a Neo probe. One copy of the integrated retroviral vector genome per cell was detected in 10 clones, and two copies in the other two clones (data not shown). Transduction with the MLV(LCMV) pseudotype therefore led to stable integration of the transgene.

Example 4

Expression of LCMV Glycoprotein (LCMV-GP) in TeLCeB-L(Arm)

Material and Methods

The preparation of the env-negative packaging line TeLCeb, which contains gag and pol of MLV as well as a retroviral vector genome with LacZ as the transgene, has already been described in detail (F. L. Cosset et al., J. Virol. 69 (1995) 7430-7436). The titration of the vector supernatants was carried out on 293-cells by X-Gal staining as has already been described (G. R. McGregor, Methods Mol. Biol. 7 (1989) 1-19). The cells were cultivated in DMEM with 10% FCS. The L(Arm) strain of LCMV is produced after several passages of LCMV in L929 cells (M. Bruns et al., Virology 177 (1990) 615-624). LCMV nucleoprotein (LCMV-NP) of L(Arm) was detected by immunofluorescence staining of the cells on slides with a polyclonal anti-LCMV rabbit serum. This standard method has already been described in detail (M. Bruns et al., Virology 177 (1990) 615-624). For the expression of LCMV-GP, the gp gene was cloned into the episomal EBV vector pCep4 (Invitrogen) which carries a hygromycin resistance gene.

Results

In the experiments for pseudotyping by the sole expression of LCMV-GP in env-negative retroviral packaging lines, a higher GP-mRNA expression was obtained with the expression plasmids than with LCM wild virus infection (FIG. 4 ). This result shows that the simultaneous presence of at least one further LCMV gene product in addition to the LCMV glycoprotein brings about an increase in glycoprotein production and promotes the formation of pseudotypes. In order to substantiate this conclusion directly, the ectopically expressed (from a plasmid) LCMV-GP was complemented with the LCMV proteins of the L(ARM) strain of LCMV. This defective strain lacks the functional glycoprotein and it therefore forms no plaques, is not pathogenic for mice and proliferates within a cell culture only over several weeks (whereas LCM wild virus does so within 24 hours). All the other gene products of L(ARM) (NP, L and Z) exhibit no detectable defects.

TeLCeb were infected with L(Arm)-containing cell culture supernatant and passages were then run for 5 weeks. Experience has shown that this is the time that the defective virus requires to infect all the cells of a culture. The complete infection of all the cells was verified by immunofluorescence staining with an anti-LCMV serum. TeLCeb-L(Arm) were transfected with pCep-GP by electroporation (electroporator from Dr. Fischer, Heidelberg) and selected for 2 weeks with hygromycin. As a control, cells were transfected with pCep4 (without GP gene). In TeLCeb-L(Arm) which were transfected with pcep-GP, pseudotypes which transferred lacZ to 293-cells were produced after selection. The titre lay between 10 2 and 10 3 /ml. This result shows clearly that the LCMV-GP in the expression plasmid described was functional and is able to pseudotype retroviral vectors.

Example 5

Pseudotypina of an HIV Vector which Expresses the Green Fluorescent Protein (GFP)

Material and Methods

The lentiviral vector HIV-GFP is derived from the infectious DNA clone pNL4-3 of HIV and has already been described in detail ( FIG. 5 ) (R. I. Connor et al., virology 206 (1995) 935-944). At the beginning of env, the NdeI cleavage site was filled in and religated as a result of which the reading frame shifts and no functional envelope protein is synthesised. Further, instead of nev, the gene for the green fluorescent protein (GFP) was cloned. The titre of the LCMV-WE strain used was determined by a plaque assay on L929 which has already been described in detail (F. Lehmann-Grube et al., J. Gen. Virol. 37 (1977) 85-92). The calcium phosphate transfections were carried out on 293 with a standard protocol (Maniatis, et al., Molecular cloning, a laboratory manual; Cold Spring Harbor Laboratory Press, 1982).

Results

293-cells were infected with an m.o.i. of 0.1 of the LCMV-WE strain. After one hour transfection was carried out with HIV-GFP and after two days the supernatants were harvested and transferred to 293-cells. The titre was determined by the GFP expression in the 293-target cells by means of immunofluorescence and lay between 10 2 and 10 3 per ml. After transfection with HIV-GFP alone (without prior infection with LCMV), no production of infectious vector particles occurred, as expected.

Example 6

Investigation of Cell Tropism

MLV(LCMV) pseudotypes infect various human cell lines: the tropism of MLV(LCMV) pseudotypes was analysed. Several human cell lines derived from cells which are attractive targets for gene therapy such as haematopoietic progenitor cells and hepatocytes were analysed. The transfer efficiency relative to mouse fibroblasts is shown in Tab. 3. All the cell lines analysed were susceptible to MLV(LCMV) pseudotypes. Even hamster cells which are normally resistant to transduction with MLV-derived vectors could be transduced efficiently with the MLV(LCMV) pseudotypes.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 : Retroviral packaging lines

The retroviral genes gag, pol and env are stably integrated into the genome of the retroviral packaging lines. Env is usually expressed separately from gag and pol. Moreover, the vector genome is expressed with the transgene and regulatory cis elements (1). The genomic RNA of the vector contains a packaging signal which was deleted on the gag, pol and env genes. In the cytoplasm, the retroviral proteins therefore package the vector genome selectively (2). A complete retroviral nucleocapsid forms (3) and is released by budding on the cell membrane (4). In so doing, retroviral envelope protein or, in the case of the pseudotypes, a foreign viral envelope protein is carried along. Outside the cell, the virus matures by proteolytic cleavage of the retroviral precursor proteins in the nucleocapsid.

FIG. 2 : The genomic RNA of the LCM virus. The genome of LCMV is composed of 2 ambisense RNA molecules each with two open reading frames. The 4 genes and their orientation are given.

FIG. 3 : The production of MLV(LCMV) pseudotypes. Packaging lines which produce no viral envelope proteins also release no infectious retroviral vectors. If such an env-negative packaging line is infected with LCM virus, the retroviruses can insert the LCMV glycoprotein into their coat. So-called pseudotypes are produced. Moreover, LCM wild virus is released during LCMV replication.

FIG. 4 : Discrepancy between high mRNA and low protein concentration in the case of ectopic GP-C expression. 293-cells were transfected with different expression constructs for LCMV glycoprotein (Ef-1 alpha promoter, alphavirus vector from Invitrogen, CMV promoter+beta globin intron, see above: preferred expression cassettes). After 2 days, the gp-mRNA concentration in the Northern blot and the GP-1/GP-2 protein quantities on the cells were measured in parallel by continuous flow cytometry. 293-cells that were infected with LCMV wild-type were used as a control. In the case of wild virus infection, the GP-1/GP-2 protein expression was 2-3 log stages above the negative control, with a relatively weak mRNA band in the Northern blot (upper band LCMV-genomic RNA, lower band gp-mRNA). In the case of ectopic expression, the protein concentration for GP-1/GP-2 was only at most one log stage above the negative control despite a higher mRNA concentration than with wild virus infection.

FIG. 5 : HIV-GFP. The infectious DNA clone of HIV pNL4-3 was cut at the beginning of the env gene with NdeI, the cleavage site was filled in and religated(s). As a result, the reading frame shifts and no functional env gene product is produced. Instead of nef, the gene for the “green fluorescent protein” (GFP) was cloned between XhoI and BamHI.

FIG. 6 : Rescue of the retroviral vector MFGlnsLacZ by LCMV.

The retroviral env-negative packaging cell line TELCeB was infected by LCMV with an m.o.i. of 0.01. Between day 1 and 7 after infection, the supernatants were replaced daily and the titres of the LCMV wild-type and LacZ vector were determined by a plaque assay on L-929 and by LacZ gene transfer to Sc-1. In addition, a part of the LCMV-infected TELCeB cells were stained daily with a monoclonal antibody directed against the LCMV glycoprotein GP-1 and analysed by continuous flow cytometry. The mean fluorescence is shown. ∘-∘ LCMV wild-type titre; □-□LacZ transfer units; Δ-Δ mean fluorescence of the LCMV glycoprotein GP expression.

FIG. 7 : MLV(LCMV) pseudotypes retain their infectiousness after ultracentrifugation.

TELCeB were infected with LCMV or amphotrophic helper virus. The supernatants were harvested and frozen. The MLV(LCMV) and amphotrophic pseudotype titres were determined. Equal quantities of the infectious virus were pelleted by ultracentrifugation and then underwent purification on a 0%-40% Urografin gradient. Vector titres and densities were determined in each fraction. ∘-∘ amphotrophic pseudotype; □-□ MLV(LCMV) pseudotype.
