The present invention relates to novel HIV protein constructs, to their use in medicine, to pharmaceutical compositions containing them and to methods of their manufacture.
In particular, the invention relates to fusion proteins comprising HIV-1 Tat and/or Nef proteins.
HIV- 1 is the primary cause of the acquired immune deficiency syndrome (AIDS), which is regarded as one of the world's major health problems. Although extensive research throughout the world has been conducted to produce a vaccine, such efforts thus far, have not been successful.
Non-envelope proteins of HIV- 1 have been described and include for example internal structural proteins such as the products of the gag and pol genes and, other non-structural proteins such as Rev, Nef, Vif and Tat (Greene et al., New England J. Med, 324, 5, 308 et seq (1991) and Bryant et al. (Ed. Pizzo), Pediatr. Infect. Dis. J., 11,5, 390 et seq (1992).
HIV Nef and Tat proteins are early proteins, that is, they are expressed early in infection and in the absence of structural proteins.
Accordingly the present invention provides a vaccine comprising a: fusion protein comprising
a) HIV Nef protein,
b) HIV tat protein, and
c) optionally a lipoprotein fusion partner.
By 'fusion partner' is meant any protein sequence that is not Tat or Nef.
Preferably the fusion partner is protein D or its' lipidated derivative Lipoprotein D,
from Haemophilius influenzae B. In particular, it is preferred that the N-terminal

unito, i.e. approximately me first 100-130 amino acids are utilised. This is represented herein as Lipo D 1/3. In a preferred embodiment of the invention the Nef protein or derivative thereof may be linked to the Tat protein or derivative thereof. Such Nef-Tat fusions may optionally also be linked to an fusion partner, such as protein D.
The fusion partner is normally linked to the N-terminus of the Nef or Tat protein.
Derivatives encompassed within the present invention include molecules with a C terminal Histidine tail which preferably comprises between 5-10 Histidine residues. Generally, a histidine tail containing n residues is represented herein as His (n). The presence of an histidine (or 'His') tail aids purification. More specifically, the invention provides proteins with the following structure
Lipo D1/3 - Nef - His Q
Lipo D 1/3 - Nef-Tat - His Q)
ProtDl/3 - Nef - His Q
ProtDl/3 - Nef-Tat - His G)
Nef-Tat - His (6)
Figure 1 provides the amino-acid (Seq. ID. No. 7) and DNA sequence (Seq. ID. No. 6) of the fusion partner for such constructs.
In a preferred embodiment the proteins are expressed with a Histidine tail comprising between 5 to 10 and preferably six Histidine residues. These are advantageous in aiding purification. Separate expression, in yeast (Saccharomyces cerevisiae), of Nef (Macreadie I.G. et aL, 1993, Yeast 9 (6) 565-573) and Tat (Braddock M et al., 1989, Cell 58 (2) 269-79) has already been reported. Nef protein only is myristilated. The present invention provides for the first time the expression of Nef and Tat separately

in a Pichia expression system (Nef-His and Tat-His constructs), and the successful expression of a fusion construct Nef-Tat-His. The DNA and amino acid sequences of representative Nef-His (Seq, ID. No.s 8 and 9), Tat-His (Seq. ID. No.s 10 and 1 l)and of Nef-Tat-His fusion proteins (Seq. ID. No.s 12 and 13)are set forth in Figure 2.
Derivatives encompassed within the present invention also include mutated proteins. The term 'mutated' is used herein to mean a molecule which has undergone deletion, addition or substitution of one or more amino acids using well known techniques for site directed mutagenesis or any other conventional method.
A mutated Tat is illustrated in Figure 2 (Seq. ID. No.s 22 and 23) as is a Nef-Tat Mutant-His (Seq. ID. No.s 24 and 25).
The present invention also provides a DNA encoding the proteins of the present invention. Such sequences can be inserted into a suitable expression vector and expressed in a suitable host.
A DNA sequence encoding the proteins of the present invention can be synthesized using standard DNA synthesis techniques, such as by enzymatic ligation as described by D.M. Roberts et al in Biochemistry 1985, 24, 5090-5098, by chemical synthesis, by in vitro enzymatic polymerization, or by PCR technology utilising for example a heat stable polymerase, or by a combination of these techniques.
Enzymatic polymerisation of DNA may be carried out in vitro using a DNA polymerase such as DNA polymerase I (Klenow fragment) in an appropriate buffer containing the nucleoside triphosphates dATP, dCTP, dGTP and dTTP as required at a temperature of 10°-37°C, generally in a volume of 50µl or less. Enzymatic ligation of DNA fragments may be carried out using a DNA ligase such as T4 DNA ligase in an appropriate buffer, such as 0.05M Tris (pH 7.4), O.OIM MgCU, O.OIM dithiothreitol, ImM spermidine, ImM ATP and O.lmg/ml bovine serum albumin, at a temperature of 4°C to ambient, generally in a volume of 50ml or less. The chemical synthesis of the DNA polymer or fragments may be carried out by conventional

phosphotriester, phosphite or phosphoramidite chemistry, using solid phase techniques such as those described in 'Chemical and Enzymatic Synthesis of Gene Fragments - A Laboratory Manual' (ed. H.G. Gassen and A. Lang), Verlag Chemie, Weinheim (1982), or in other scientific publications, for example M.J. Gait, H.W.D. Matthes, M. Singh, B.S. Sproat, and R.C. Titmas, Nucleic Acids Research, 1982,10, 6243; B.S. Sproat, and W. Bannwarth, Tetrahedron Letters, 1983, 24, 5771; M.D. Matteucci and M.H. Caruthers, Tetrahedron Letters, 1980, 21,719; M.D. Matteucci and M.H. Caruthers, Journal of the American Chemical Society, 1981, 103, 3185; S.P. Adams et ai, Journal of the American Chemical Society, 1983, 105, 661; N.D. Sinha, J. Biemat, J. McMannus, and H. Koester, Nucleic Acids Research, 1984,12, 4539; and H.W.D. Matthes et al, EMBO Journal, 1984, 3, 801.
The invention also provides a process for preparing a protein of the invention, the process comprising the steps of:
i) preparing a replicable or integrating expression vector
capable, in a host cell, of expressing a DNA polymer comprising a nucleotide sequence that encodes the protein or a derivative thereof
ii) transforming a host cell with said vector
iii) culturing said transformed host cell under conditions
permitting expression of said DNA polymer to produce said protein; and
iv) recovering said protein
The process of the invention may be performed by conventional recombinant techniques such as described in Maniatis et al, Molecular Cloning - A Laboratory Manual; Cold Spring Harbor, 1982-1989.
The term 'transforming' is used herein to mean the introduction of foreign DNA into a host cell. This can be achieved for example by transformation, transfection or

infection with an appropriate plasmid or viral vector using e.g. conventional techniques as described in Genetic Engineering; Eds. S.M. Kingsman and A.J. Kingsman; Blackwell Scientific Publications; Oxford, England, 1988. The term 'transformed' or 'transformant' will hereafter apply to the resulting host cell containing and expressing the foreign gene of interest.
The expression vectors are novel and also form part of the invention.
The replicable expression vectors may be prepared in accordance with the invention, by cleaving a vector compatible with the host cell to provide a linear DNA segment having an intact replicon, and combining said linear segment with one or more DNA molecules which, together with said linear segment encode the desired product, such as the DNA polymer encoding the protein of the invention, or derivative thereof, under ligating conditions.
Thus, the DNA polymer may be preformed or formed during the construction of the vector, as desired.
The choice of vector will be determined in part by the host cell, which may be prokaryotic or eukaryotic but preferably is E. coli or yeast. Suitable vectors include plasmids, bacteriophages, cosmids and recombinant viruses.
The preparation of the replicable expression vector may be carried out conventionally with appropriate enzymes for restriction, polymerisation and ligation of the DNA, by procedures described in, for example, Maniatis et al cited above.
The recombinant host cell is prepared, in accordance with the invention, by transforming a host cell with a replicable expression vector of the invention under transforming conditions. Suitable transforming conditions are conventional and are described in, for example, Maniatis et al cited above, or "DNA Cloning" Vol. II, D.M. Glover ed., IRL Press Ltd, 1985.

The choice of transforming conditions is determined by the host cell. Thus, a bacterial host such as E. coli may be treated with a solution of CaCl2 (Cohen ei al., Proc. Nat. Acad. Sci., 1973, 69, 2110) or with a solution comprising a mixture of RbCl, MnCl2, potassium acetate and glycerol, and then with 3-[N-morpholino]-propane-sulphonic acid, RbCl and glycerol. Mammalian cells in culture may be transformed by calcium co-precipitation of the vector DNA onto the cells. The invention also extends to a host cell transformed with a replicable expression vector of the invention.
Culturing the transformed host cell under conditions permitting expression of the DNA polymer is carried out conventionally, as described in, for example, Maniatis et al and "DNA Cloning" cited above. Thus, preferably the cell is supplied with nutrient and cultured at a temperature below 50°C.
The product is recovered by conventional methods according to the host cell. Thus, where the host cell is bacterial, such as E. coli - or yeast such as Pichia; it may be lysed physically, chemically or enzymatically and the protein product isolated from the resulting lysate. Where the host cell is mammalian, the product may generally be isolated from the nutrient medium or from cell free extracts. Conventional protein isolation techniques include selective precipitation, adsorption chromatography, and affinity chromatography including a monoclonal antibody affinity column.
For proteins of the present invention provided with Histidine tails, purification can easily be achieved by the use of a metal ion affinity column. In a preferred embodiment, the protein is further purified by subjecting it to cation ion exchange chromatography and/or Gel filtration chromatography. The protein is then sterilised by passing through a 0.22 µm membrane.
The proteins of the invention can then be formulated as a vaccine, or the Histidine residues enzymatically cleared.

The proteins of the present invention are provided preferably at least 80% pure more preferably 90% pure as visualised by SDS PAGE. Preferably the proteins appear as a single band by SDS PAGE.
The present invention also provides pharmaceutical composition comprising a protein of the present invention in a pharmaceutically acceptable excipient.
Vaccine preparation is generally described in New Trends and Developments in Vaccines, Voller et aL (eds.), University Park Press, Baltimore, Maryland, 1978. Encapsulation within liposomes is described by FuUerton, US Patent 4,235,877.
The proteins of the present invention are preferably adjuvanted in the vaccine formulation of the invention. Suitable adjuvants include an aluminium salt such as aluminium hydroxide gel (alum) or aluminium phosphate, but may also be a salt of calcium, iron or zinc, or may be an insoluble suspension of acylated tyrosine, or acylated sugars, cationically or anionically derivatised polysaccharides, or polyphosphazenes.
In the formulation of the inventions it is preferred that the adjuvant composition induces a preferential THl response. Suitable adjuvant systems include, for example, a combination of monophosphoryl lipid A or derivative thereof, preferably 3-de-O-acylated monophosphoryl lipid A (3D-MPL) together with an aluminium salt.
An enhanced system involves the combination of a monophosphoryl lipid A and a saponin derivative particularly the combination of QS21 and 3D- MPL as disclosed in WO 94/00153, or a less reactogenic composition where the QS21 is quenched with cholesterol as disclosed in WO 96/33739.
A particularly potent adjuvant formulation involving QS21, 3D-MPL & tocopherol in an oil in water emulsion is described in WO 95/17210 and is a preferred formulation.

Accordingly in one embodiment of the present invention there is provided a vaccine comprising a protein according to the invention adjuvanted with a monophosphoryl lipid A or derivative thereof, especially 3D-MPL.
Preferably the vaccine additionally comprises a saponin, more preferably QS21.
Preferably the formulation additional comprises an oil in water emulsion and tocopherol. The present invention also provides a method for producing a vaccine formulation comprising mixing a protein of the present invention together with a pharmaceutically acceptable excipient, such as 3D-MPL.
The vaccine of the present invention may additional comprise further HIV proteins, such as the envelope glycoprotein gpl60 or its derivative gp 120.
In another aspect, the invention relates to an HIV Nef or an HIV Tat protein or derivative thereof expressed in Pichia pastor is.
The invention will be further described by reference to the following examples:
EXAMPLES:
GJeneral
Nef and Tat proteins, two regulatory proteins encoded by the human immunodeficiency virus (HIV-1) were produced in E.coli and in the methylotrophic yeast Pichia pastor is.
The we/gene from the Bru/Lai isolate (Cell 40: 9-17,1985) was selected for these constructs since this gene is among those that are most closely related to the consensus Nef.

The starting material for the Bru/Lai ne/gene was a 1170bp DNA fragment cloned on the mammalian expression vector pcDNA3 (pcDNA3/nef).
The tat gene originates from the BH10 molecular clone. This gene was received as an HTLV III cDNA clone named pCVl and described in Science, 229, p69-73, 1985.
1. EXPRESSION OF HIV-1 nef AND tat SEQUENCES IN E.COLL
Sequences encoding the Nef protein as well as a fusion of nef and tat sequences were placed in plasmids vectors: pRIT14586 and pRIT14589 (see figure 1).
Nef and the Nef-Tat fusion were produced as fusion proteins using as fusion partner a part of the protein D. Protein D is an immunoglobulin D binding protein exposed at the surface of the gram-negative bacterium Haemophilus influenzae.
pRIT14586 contains, under the control of a A.PL promoter, a DNA sequence derived from the bacterium Haemophilus influenzae which codes for the first 127 amino acids of the protein D (Infect. Immun. 60 : 1336-1342, 1992), immediately followed by a multiple cloning site region plus a DNA sequence coding for one glycine, 6 histidines residues and a stop codon (Fig. 1 A).
This vector is designed to express a processed lipidated His tailed fusion protein (LipoD fusion protein). The fusion protein is synthesised as a precursor with an 18 amino acid residues long signal sequence and after processing, the cysteine at position 19 in the precursor molecule becomes the amino terminal residue which is then modified by covalently bound fatty acids (Fig.IB).
pRIT14589 is almost identical to pRIT14586 except that the protD derived sequence starts immediately after the cysteine 19 codon.
Expression from this vector resuhs in a His tailed, non lipidated fusion protein (Prot D fusion protein).

Four constructs were made: LipoD-nef-His, LipoD-nef-tat-His, ProtD-nef-His, and ProtD-nef/-tat-His.
The first two constructs were made using the expression vector pRIT14586, the last two constructs used pRIT14589.

E.coli AR58 strain was transformed with pRIT 14601 and transformants were analysed as described previously. The transformant selected received laboratory accession number ECD-NTl.

2. EXPRESSION OF HIV-1 nef ANB tat SEQUENCES IN PICHIA PASTORIS.
Nef protein, Tat protein and the fusion Nef-Tat were expressed in the methylotrophic yeast Pichia past oris under the control of the inducible alcohol oxidase (AOXl) promoter.
To express these HIV-1 genes a modified version of the integrative vector PHIL-D2 (INVITROGEN) was used. This vector was modified in such a way that expression of heterologous protein starts immediately after the native ATG codon of the AOXl gene and will produce recombinant protein with a tail of one glycine and six histidines residues . This PHIL-D2-M0D vector was constructed by cloning an oligonucleotide linker between the adjacent AsuII and EcoRI sites of PHIL-D2 vector (see Figure 3). In addition to the His tail, this linker carries Ncol, Spel and Xbal restriction sites between which nef, tat and nef-tat fusion were inserted.
2.1 CONSTRUCTION OF THE INTEGRATIVE VECTORS pRIT14597 (encoding Nef-His protein), pRIT14598 (encoding Tat-His protein) and pRIT14599 (encoding fusion Nef-Tat-His).
The nef gene was amplified by PCR from the pcDNA3/Nef plasmid with primers 01 and 02(see section 1.1.1 construction of pRIT14595).The PCR fragment obtained and the integrative PHIL-D2-M0D vector were both restricted by Ncol and Spel, purified on agarose gel and ligated to create the integrative plasmid pRIT14597 (see Figure 3).
The tat gene was amplified by PCR from a derivative of the pCVl plasmid with primers 05 and 04(see section 1.3.1 construction of pRIT14596):

An Ncol restriction site was introduced at the 5' end of the PCR fragment while a Spel site was introduced at the 3' end with primer 04. The PCR fragment obtained and the PHIL-D2-M0D vector were both restricted by Ncol and Spel, purified on agarose gel and ligated to create the integrative plasmid pRIT14598.
To construct pRIT 14599, a 910bp DNA fragment corresponding to the nef-tat-His coding sequence was ligated between the EcoRI blunted(T4 polymerase) and Ncol sites of the PHIL-D2-M0D vector. The nef-tat-His coding fragment was obtained by Xbal blunted(T4 polymerase) and Ncol digestions of pRIT14596.
2.2 TRANSFORMATION OF PICHIA PASTORIS STRAIN GS115(his4).
To obtain Pichia pastoris strains expressing Nef-His, Tat-His and the fusion Nef-Tat-His, strain GS115 was transformed with linear NotI fragments carrying the respective expression cassettes plus the HIS4 gene to complement his4 in the host genome.Transformation of GS115 with Notl-linear fragments favors recombination at the AOXI locus.
Multicopy integrant clones were selected by quantitative dot blot analysis and the type of integration, insertion (Mufphenotype) or transplacement (Mut'phenotype), was determined.

An Ncol restriction site was introduced at the 5' end of the PCR fragment while a Spel site was introduced at the 3' end with primer 04. The PCR fragment obtained and the PHIL-D2-M0D vector were both restricted by Ncol and Spel, purified on agarose gel and ligated to create the integrative plasmid pRIT14912

To construct pRIT14913, the tat mutant gene was amplified by PCR from the pCMVLys41/KGE plasmid with primers 03 and 04 (see section 1.3.1 construction of pRIT14596).

3.2 TRANSFORMATION OF PICHIA PASTORIS STRAIN GS115.
Pichia pastoris strains expressing Tat mutant-His protein and the fusion Nef-Tat mutant-His were obtained, by applying integration and recombinant strain selection strategies previously described in section 2.2 .
Two recombinant strains producing Tat mutant-His protein ,a 95 amino-acids protein, were selected: Y1775 (Mut+ phenotype) and Y1776(Muts phenotype).

5. VACCINE PREPARATION
A vaccine prepared in accordance with the invention comprises the expression product of a DNA recombinant encoding an antigen as exemplified in example 1 or 2 and as adjuvant, the formulation comprising a mixture of 3 de -0-acylated monophosphoryl lipid A 3D-MPL and QS21 in an oil/water emulsion.
3D-MPL: is a chemically detoxified form of the lipopoly saccharide (LPS) of the Gram-negative bacteria Salmonella minnesota.
Experiments performed at Smith Kline Beecham Biologicals have shown that 3D-MPL combined with various vehicles strongly enhances both the humoral and a THl type of cellular immunity.
QS21: is one saponin purified from a crude extract of the bark of the Quillaja Saponaria Molina tree, which has a strong adjuvant activity: it activates both antigen-specific lymphoproliferation and CTLs to several antigens. Experiments performed at Smith Kline Beecham Biologicals have demonstrated a clear synergistic effect of combinations of 3D-MPL and QS21 in the induction of both humoral and THl type cellular immune responses.
The oil/water emulsion is composed of 2 oils (a tocopherol and squalene), and of PBS containing Tween 80 as emulsifier. The emulsion comprised 5% squalene 5%

tocopherol 0.4% Tween 80 and had an average particle size of 180 nm (see WO 95/17210).
Experiments performed at Smith Kline Beecham Biologicals have proven that the adjunction of this 0/W emulsion to 3D-MPL/QS21 further increases their immunostimulant properties.
Preparation of the oil/water emulsion (2 fold concentrate)
Tween 80 is dissolved in phosphate buffered saline (PBS) to give a 2% solution in the PBS. To provide 100ml two fold concentrate emulsion 5g of DL alpha tocopherol and 5ml of squalene are vortexed to mix thoroughly. 90ml of PBS/Tween solution is added and mixed thoroughly. The resulting emulsion is then passed through a syringe and finally microfluidised by using an Ml 1 OS microfluidics machine. The resulting oil droplets have a size of approximately 180 nm.
Preparation of oil in water formulation.
Antigen prepared in accordance with example 1 or 2 (5µg) was diluted in 10 fold concentrated PBS pH 6.8 and H2O before consecutive addition of SB62, 3D-MPL (5 µg), QS21 (5|ig) and 50 |ig/ml thiomersal as preservative at 5 min interval. The emulsion volume is equal to 50% of the total volume (50µl for a dose of 100µl).
All incubations were carried out at room temperature with agitation.
6. IMMUNOGENICITY OF Tat AND Nef-Tat IN RODENTS
Characterization of the immune response induced after immunization with Tat and NefTat was carried out. To obtain information on isotype profiles and cell-mediated immunity (CMI) two immunization experiments in mice were conducted. In the first experiment mice were immunized twice two weeks apart into the footpad with Tat or

NefTat in the oxydized or reduced form, respectively. Antigens were formulated in an oil in water emulsion comprising squalene, tween 80 Tm (polyoxyethylene sorbitan monooleate) QS21, 3D-MPL and a-tocopherol, and a control group received the adjuvant alone. Two weeks after the last immunization sera were obtained and subjected to Tat-specific ELISA (using reduced Tat for coating) for the determination of antibody titers and isotypes (Figure 6a). The antibody titers were highest in the mice having received oxydized Tat. In general, the oxydized molecules induced higher antibody titers than the reduced forms, and Tat alone induced higher antibody titers than NefTat. The latter observation was confirmed in the second experiment. Most interestingly, the isotype profile of Tat-specific antibodies differed depending on the antigens used for immunization. Tat alone elicited a balanced IgGland IgG2a profile, while NefTat induced a much stronger TH2 bias (Figure 6b). This was again confirmed in the second experiment.
In the second mouse experiment animals received only the reduced forms of the molecules or the adjuvant alone. Besides serological analysis (see above) lymphoproliferative responses from lymph node cells were evaluated. After restimulation of those cells in vitro with Tat or NefTat ^H-thymidine incorporation was measured after 4 days of culture. Presentation of the results as stimulation indices indicates that very strong responses were induced in both groups of mice having received antigen (Figure 7).
In conclusion, the mice studies indicate that Tat as well as Nef-Tat are highly immunogenic candidate vaccine antigens. The immune response directed against the two molecules is characterized by high antibody responses with at least 50% IgGl. Furthermore, strong CMI responses (as measured by lymphoproliferation) were observed.
7. FUNCTIONAL PROPERTIES OF THE Tat AND Nef-Tat PROTEINS
The Tat and NefTat molecules in oxydized or reduced form were investigated for their ability to bind to human T cell lines. Furthermore, the effect on growth of

those cell lines was assessed. ELISA plates were coated overnight with different concentration of the Tat and NefTat proteins, the irrelevant gD from herpes simplex virus type II, or with a buffer control alone. After removal of the coating solution HUT-78 cells were added to the wells. After two hours of incubation the wells were washed and binding of cells to the bottom of the wells was assessed microscopically. As a quantitative measure cells were stained with toluidine blue, lysed by SDS, and the toluidine blue concentration in the supernatant was determined with an ELISA plate reader. The results indicate that all four proteins, Tat and NefTat in oxydized or reduced form mediated binding of the cells to the ELISA plate (Figure 8). The irrelevant protein (data not shown) and the buffer did not fix the cells. This indicates that the recombinantly expressed Tat-containing proteins bind specifically to human T cell lines.
In a second experiment HUT-78 cells were left in contact with the proteins for 16 hours. At the end of the incubation period the cells were labeled with [^H]-thymidine and the incorporation rate was determined as a measure of cell growth. All four proteins included in this assay inhibited cell growth as judged by diminished radioactivity incorporation (Figure 9). The buffer control did not mediate this effect. These results demonstrate that the recombinant Tat-containing proteins are capable of inhibiting growth of a human T cell line.
In summary the functional characterization of the Tat and NefTat proteins reveals that these proteins are able to bind to human Tcell lines. Furthermore, the proteins are able to inhibit growth of such cell lines.
