The present invention relates to the field of antimicrobial prophylaxis and therapy. In particular the present invention relates to novel proteins and polynucleotides derived from Klebsiella pneumoniae. The invention further relates to vectors comprising the polynucleotides, transformed host organisms expressing the polynucleotides, antibodies (mono- or polyclonal) specific for the polypeptides as well as diagnostic, prophylactic and therapeutic uses and methods. Finally, also methods of preparation are part of the invention.
Bacterial infections are in most instances successfully treated by administration of antibiotics to patients in need thereof. However, due to careless or thoughtless use of powerful antibiotics, many pathological germs become resistant against antibiotics over time. One threatening example is Klebsiella pneumoniae.
The genus Klebsiella belongs to the family Enterobacteriaceae and is divided into at least 4 species. They are gram-negative, capsulated, oxidase-negative, non-motile, straight rods. They are facultative anaerobes, having both a respiratory and fermnentative metabolism. Most strains can use citrate and glucose as their sole carbon source. Some strains can fix nitrogen. They are commonly found in the intestines, clinical samples, soil, water and grains. The species Klebsiella pneumoniae can be divided into 3 subspecies; pneumoniae, ozaenae and rhinoscleromatis (Orskov, I. 1984. Genus V. Klebsiella Trevisan 1885, 105. Krieg and Holt (editors) In Bergey's Manual of Systematic Bacteriology, 1:461-465). Klebsiella pneumoniae is the most common gram-negative pathogen causing community acquired pneumonia (Carpenter, J., et al, 1990. Rev Infect. Dis. 12:672-682). Klebsiella is also responsible for an estimated 8% of all nosocomial infections (Sahly, H. and Podschun, R., 1997. Clin. Diagn. Lab. Immunol. 4:393-399).
K. pneumoniae is an opportunistic pathogen that is associated with pneumonia, septicemia, meningitis, endocarditis, ventriculitis, and infections of urinary tract and wounds. These diseases are both nosocomial and community acquired. K. pneumoniae also plays a large role in two major nonrheumatoid arthritic diseases, Ankylosing Spondylitis and Reiter's Syndrome (Schwimmbeck, P. and Oldstone, M., 1989. Current Topics in Microbiology and Immunology. 145:45-56.). Despite available antibiotics, observed mortality rates for pneumonia are approximately 50%, but when bacteremic K. pneumoniae occurs in alcoholics, the mortality rises to almost 100% (Sahly, H. and Podschun, R., 1997. Clin. Diagn. Lab. Immunol. 4:393-399). The overall mortality rate for Klebsiella bacteremia in one study was 37% and has ranged in others from 25% to 55% (Watanakunakron, C. and Jura, J., 1991. Scand. J. Infect. Dis. 23:399-405).
Incidence of K. pneumoniae meningitis is on the rise. A study of 3377 cases of Bacterial meningitis in 1948, found only 7 were K. pneumoniae. In 1957, K. pneumonia accounted for 1.5% of all cases of meningitis. In an eleven-year study, from 1981 to 1991, 13% of culture proven bacterial meningitis cases were K. pneumoniae. There was an increase occurrence of K. pneumoniae meningitis within this study with 7% occurrence in the first 6 years, and 16% occurrence in the last 5 years (Tang, L-M and Chen, S-T., 1994. Scand. J. Infect. Dis. 26:95-102).
In recent years, Klebsiella strains have become multi-resistant to many antibiotics. In the 1970's, the resistance was mainly to aminoglycoside antibiotics. Since 1982, some Klebsiella strains have become resistant to the extended-spectrum cephalosporins (Sahly, H. and Podschun, R., 1997. Clin. Diagn. Lab. Immunol. 4:393-399). Resistance to the extended-spectrum cephalosporins among clinical isolates of Klebsiella in France and England has been reported at 14 to 16% (Sirot, D. 1995 J. Antimicrob. Chemother. 36:19-34). Since Klebsiella is a good recipient for R factors, resistance has been gained to β-lactams, tetracycline, chloramphenicols, ceftazidime, sulfonamides and trimethoprim. Today, almost all strains of Klebsiella are resistant to ampicillin. (Orskov, I. 1984. Genus V. Klebsiella Trevisan 1885, 105. Krieg and Holt (editors) In Bergey's Manual of Systematic Bacteriology, 1:461-465).
Microbial fermentation is an important way to convert renewable resources to products of biological and industrial importance. K. pneumoniae has been used to convert simple sugars to the commodity chemicals 1,3-propanediol and 1,2-propanediol. These products have been made by fed-batch fermentation of glycerol by K. pneumoniae. (Cameron, D. et al, 1998. Biotechnol. Prog. 14:116-125). Genes from the 1,3-propanediol pathway of K. pneumoniae have recently been cloned and expressed into both E. coli and S. cerevisiae. Metabolic engineering of these genes can significantly improve the product yield and productivity (Cameron, D. et al, 1998. Biotechnol. Prog. 14:116-125).
With K. pneumoniae playing the lead role, the Klebsiella genus is becoming an increasingly important pathogen. Over the past 10 years, discovery of multi-drug resistant strains has emphasized the importance of this genus. Furthermore, Klebsiella is considered to be a model for systemic infections caused by capsulated bacteria.
Vaccination is considered to be a very effective method of preventing infectious diseases in human and veterinary health care. Vaccination is the administration of immungenically effective amounts of antigenic material (the vaccine) to produce immunity to a disease/disease-causing pathogenic agent. Vaccines have contributed to the eradication of smallpox, the near eradication of polio, and the control of a variety of diseases, including rubella, measles, mumps, chickenpox, typhoid fever.
Before “the genomic era”, vaccines were based on killed or live attenuated, microorganisms, or parts purified from them. Subunit vaccines are considered as a modern upgrade of these types of vaccine, as the subunit vaccines contain one or more protective antigens, which are more or less the weak spot of the pathogen. Hence, in order to develop subunit vaccines, it is critical to identify the proteins, which are important for inducing protection and to eliminate others.
An antigen is said to be protective if it is able to induce protection from subsequent challenge by a disease-causing infectious agent in an appropriate animal model following immunization.
The empirical approach to subunit vaccine development, which includes several steps, begins with pathogen cultivation, followed by purification into components, and then testing of antigens for protection. Apart from being time and labour consuming, this approach has several limitations that can lead to failure. It is not possible to develop vaccines using this approach for microorganisms, which cannot easily be cultured and only allows for the identification of the antigens, which can be obtained in sufficient quantities. The empirical approach has a tendency to focus on the most abundant proteins, which in some cases are not immuno-protective. In other cases, the antigen expressed during in vivo infection is not expressed during in vitro cultivation. Furthermore, antigen discovery by use of the empirical approach demands an extreme amount of proteins in order to discover the protective antigens, which are like finding needles in the haystack. This renders it a very expensive approach, and it limits the vaccine development around diseases, which is caused by pathogens with a large genome or disease areas, which perform badly in a cost-effective perspective.
It is an object of embodiments of the invention to provide K. pneumoniae derived antigenic polypeptides that may serve as constituents in vaccines against K. pneumoniae infections and in diagnosis of K. pneumoniae infections. It is also an object to provide nucleic acids, vectors, transformed cells, vaccine compositions, and other useful means for molecular cloning as well as for therapy and diagnosis with relevance for K. pneumoniae.
It has been found by the present inventor(s) that K. pneumoniae, in particular drug resistant K. pneumoniae, expresses a number of hitherto unknown putatively surface exposed proteins which are candidates as vaccine targets as well as candidates as immunizing agents for preparation of antibodies that target K. pneumoniae.

The term “polypeptide” is in the present context intended to mean both short peptides of from 2 to 10 amino acid residues, oligopeptides of from 11 to 100 amino acid residues, and polypeptides of more than 100 amino acid residues. Furthermore, the term is also intended to include proteins, i.e. functional biomolecules comprising at least one polypeptide; when comprising at least two polypeptides, these may form complexes, be covalently linked, or may be non-covalently linked. The polypeptide (s) in a protein can be glycosylated and/or lipidated and/or comprise prosthetic groups.
The term “subsequence” means any consecutive stretch of at least 3 amino acids or, when relevant, of at least 3 nucleotides, derived directly from a naturally occurring amino acid sequence or nucleic acid sequence, respectively
The term “amino acid sequence” s the order in which amino acid residues, connected by peptide bonds, lie in the chain in peptides and proteins.
The term “adjuvant” has its usual meaning in the art of vaccine technology, i.e. a substance or a composition of matter which is 1) not in itself capable of mounting a specific immune response against the immunogen of the vaccine, but which is 2) nevertheless capable of enhancing the immune response against the immunogen. Or, in other words, vaccination with the adjuvant alone does not provide an immune response against the immunogen, vaccination with the immunogen may or may not give rise to an immune response against the immunogen, but the combined vaccination with immunogen and adjuvant induces an immune response against the immunogen which is stronger than that induced by the immunogen alone.
“Sequence identity” is in the context of the present invention determined by comparing 2 optimally aligned sequences of equal length (e.g. DNA, RNA or amino acid) according to the following formula: (Nref−Ndif)·100/Nref, wherein Nref is the number of residues in one of the 2 sequences and Ndif is the number of residues which are non-identical in the two sequences when they are aligned over their entire lengths and in the same direction. So, two sequences 5′-ATTCGGAACC-3′ and 5′-ATACGGGACC-3′ will provide the sequence identity 80% (Nref=10 and Ndif=2).
An “assembly of amino acids” means two or more amino acids bound together by physical or chemical means.
The “3D conformation” is the 3 dimensional structure of a biomolecule such as a protein. In monomeric polypeptides/proteins, the 3D conformation is also termed “the tertiary structure” and denotes the relative locations in 3 dimensional space of the amino acid residues forming the polypeptide.
“An immunogenic carrier” is a molecule or moiety to which an immunogen or a hapten can be coupled in order to enhance or enable the elicitation of an immune response against the immunogen/hapten. Immunogenic carriers are in classical cases relatively large molecules (such as tetanus toxoid, KLH, diphtheria toxoid etc.) which can be fused or conjugated to an immunogen/hapten, which is not sufficiently immunogenic in its own right—typically, the immunogenic carrier is capable of eliciting a strong T-helper lymphocyte response against the combined substance constituted by the immunogen and the immunogenic carrier, and this in turn provides for improved responses against the immungon by 5-lymphocytes and cytotoxic lymphocytes. More recently, the large carrier molecules have to a certain extent been substituted by so-called promiscuous T-helper epitopes, i.e. shorter peptides that are recognized by a large fraction of HLA haplotypes in a population, and which elicit T-helper lymphocyte responses.
A “T-helper lymphocyte response” is an immune response elicited on the basis of a peptide, which is able to bind to an MHC class II molecule (e.g. an HLA class II molecule) in an antigen-presenting cell and which stimulates T-helper lymphocytes in an animal species as a consequence of T-cell receptor recognition of the complex between the peptide and the MHC Class II molecule prese
An “immunogen” is a substance of matter which is capable of inducing an adaptive immune response in a host, whose immune system is confronted with the immunogen. As such, immunogens are a subset of the larger genus “antigens”, which are substances that can be recognized specifically by the immune system (e.g. when bound by antibodies or, alternatively, when fragments of the are antigens bound to MHC molecules are being recognized by T-cell receptors) but which are not necessarily capable of inducing immunity—an antigen is, however, always capable of eliciting immunity, meaning that a host that has an established memory immunity against the antigen will mount a specific immune response against the antigen.
A “hapten” is a small molecule, which can neither induce or elicit an immune response, but if conjugated to an immunogenic carrier, antibodies or TCRs that recognize the hapten can be induced upon confrontation of the immune system with the hapten carrier conjugate.
An “adaptive immune response” is an immune response in response to confrontation with an antigen or immunogen, where the immune response is specific for antigenic determinants of the antigen/immunogen—examples of adaptive immune responses are induction of antigen specific antibody production or antigen specific induction/activation of T helper lymphocytes or cytotoxic lymphocytes.
A “protective, adaptive immune response” is an antigen-specific immune response induced in a subject as a reaction to immunization (artificial or natural) with an antigen, where the immune response is capable of protecting the subject against subsequent challenges with the antigen or a pathology-related agent that includes the antigen. Typically, prophylactic vaccination aims at establishing a protective adaptive immune response against one or several pathogens.
“Stimulation of the immune system” means that a substance or composition of matter exhibits a general, non-specific immunostimulatory effect. A number of adjuvants and putative adjuvants (such as certain cytokines) share the ability to stimulate the immune system. The result of using an immunostimulating agent is an increased “alertness” of the immune system meaning that simultaneous or subsequent immunization with an immunogen induces a significantly more effective immune response compared to isolated use of the immunogen.
Hybridization under “stringent conditions” is herein defined as hybridization performed under conditions by which a probe will hybridize to its target sequence, to a detectably greater degree than to other sequences. Stringent conditions are target-sequence-dependent and will differ depending on the structure of the polynucleotide. By controlling the stringency of the hybridization and/or washing conditions, target sequences can be identified which are 100% complementary to a probe (homologous probing). Alternatively, stringency conditions can be adjusted to allow some mismatching in sequences so that lower degrees of similarity are detected (heterologous probing). Specificity is typically the function of post-hybridization washes, the critical factors being the ionic strength and temperature of the final wash solution. Generally, stringent wash temperature conditions are selected to be about 5° C. to about 2° C. lower than the melting point (Tm) for the specific sequence at a defined ionic strength and pH. The melting point, or denaturation, of DNA occurs over a narrow temperature range and represents the disruption of the double helix into its complementary single strands. The process is described by the temperature of the midpoint of transition, Tm, which is also called the melting temperature. Formulas are available in the art for the determination of melting temperatures.
The term “animal” is in the present context in general intended to denote an animal species (preferably mammalian), such as Homo sapiens, Canis domesticus, etc. and not just one single animal. However, the term also denotes a population of such an animal species, since it is important that the individuals immunized according to the method of the invention substantially all will mount an immune response against the immunogen of the present invention.
As used herein, the term “antibody” refers to a polypeptide or group of polypeptides composed of at least one antibody combining site. An “antibody combining site” is the three-dimensional binding space with an internal surface shape and charge distribution complementary to the features of an epitope of an antigen, which allows a binding of the antibody with the antigen. “Antibody” includes, for example, vertebrate antibodies, hybrid antibodies, chimeric antibodies, humanised antibodies, altered antibodies, univalent antibodies, Fab proteins, and single domain antibodies.
“Specific binding” denotes binding between two substances which goes beyond binding of either substance to randomly chosen substances and also goes beyond simple association between substances that tend to aggregate because they share the same overall hydrophobicity or hydrophilicity. As such, specific binding usually involves a combination of electrostatic and other interactions between two conformationally complementary areas on the two substances, meaning that the substances can “recognize” each other in a complex mixture.
The term “vector” is used to refer to a carrier nucleic acid molecule into which a heterologous nucleic acid sequence can be inserted for introduction into a cell where it can be replicated and expressed. The term further denotes certain biological vehicles useful for the same purpose, e.g. viral vectors and phage—both these infectious agents are capable of introducing a heterologous nucleic acid sequence
The term “expression vector” refers to a vector containing a nucleic acid sequence coding for at least part of a gene product capable of being transcribed. In some cases, when the transcription product is an mRNA molecule, this is in turn translated into a protein, polypeptide, or peptide.
In some embodiments the at least or exactly 5 contiguous amino acids referred to in option b) in the definition of the first aspect of the invention constitute at least or exactly 5, at least or exactly or at most 6, at least or exactly or at most 7, at least or exactly or at most 8, at least or exactly or at most 9, at least or exactly or at most 10, at least or exactly or at most 11, at least or exactly or at most 12, at least or exactly or at most 13, at least or exactly or at most 14, at least or exactly or at most 15, at least or exactly or at most 16, at least or exactly or at most 17, at least or exactly or at most 18, at least or exactly or at most 19, at least or exactly or at most 20, at least or exactly or at most 21, at least or exactly or at most 22, at least or exactly or at most 23, at least or exactly or at most 24, at least or exactly or at most 25, at least or exactly or at most 26, at least or exactly or at most 27 at least or exactly or at most 28, at least or exactly or at most 29, at least or exactly or at most 30, at least or exactly or at most 31, at least or exactly or at most 32, at least or exactly or at most 33, at least or exactly or at most 34, at least or exactly or at most 35, at least or exactly or at most 36, at least or exactly or at most 37, at least or exactly or at most 38, at least or exactly or at most 39, at least or exactly or at most 40, at least or exactly or at most 41, at least or exactly or at most 42, at least or exactly or at most 43, at least or exactly or at most 44, at least or exactly or at most 45, at least or exactly or at most 46, at least or exactly or at most 47, at least or exactly or at most 48, at least or exactly or at most 49, at least or exactly or at most 50, at least or exactly or at most 51, at least or exactly or at most 52, at least or exactly or at most 53, at least or exactly or at most 54, at least or exactly or at most 55, at least or exactly or at most 56, at least or exactly or at most 57, at least or exactly or at most 58, at least or exactly or at most 59, at least or exactly or at most 60, at least or exactly or at most 61, at least or exactly or at most 62, at least or exactly or at most 63, at least or exactly or at most 64, at least or exactly or at most 65, at least or exactly or at most 66, at least or exactly or at most 67, at least or exactly or at most 68, at least or exactly or at most 69, at least or exactly or at most 70, at least or exactly or at most 71, at least or exactly or at most 72, at least or exactly or at most 73, at least or exactly or at most 74, at least or exactly or at most 75, at least or exactly or at most 76, at least or exactly or at most 77, at least or exactly or at most 78, at least or exactly or at most 79, at least or exactly or at most 80, at least or exactly or at most 81, at least or exactly or at most 82, at least or exactly or at most 83, at least or exactly or at most 84, at least or exactly or at most 85, at least or exactly or at most 86, at least or exactly or at most 87, at least or exactly or at most 88, at least or exactly or at most 89, at least or exactly or at most 90, at least or exactly or at most 91, at least or exactly or at most 92, and at least or exactly or at most 93 contiguous amino acid residues.
The number of contiguous amino acids can be higher, for all of SEQ ID NOs: 2-30. Another way to phrase this is that for each of SEQ ID NOs: 1-30, 93, and 94, the number of the contiguous amino acid residues is at least or exactly or at most N-n, where N is the length of the sequence ID in question and n is any integer between N−5 and 0; that is, the at least 5 contiguous amino acids can be at least any number between 5 and the length of the reference sequence minus one, in increments of one. Consequently:

The polypeptide of the invention is in certain embodiments also fused or conjugated to an immunogenic carrier molecule; or, phrased otherwise, the polypeptide of the invention also includes such an immunogenic carrier molecule in addition to the material derived from SEQ ID NOs: 1-30. The immunogenic carrier molecule is a typically polypeptide that induces T-helper lymphocyte responses in a majority of humans, such as immunogenic carrier proteins selected from the group consisting of keyhole limpet hemocyanino or a fragment thereof, tetanus toxoid or a fragment thereof, dipththeria toxoid or a fragment thereof. Other suitable carrier molecules are discussed infra. One further fusion partner which is preferably incorporated is a “His tag”, i.e. a stretch of amino acids, which is rich in or only consists of histidinyl residues so as to facilitate protein purification.
In preferred embodiments, the polypeptide of the invention detailed above is capable of inducing an adaptive immune response against the polypeptide in a mammal, in particular in a human being. Preferably, the adaptive immune response is a protective adaptive immune response against infection with K. pneumoniae. The polypeptide may in these cases induce a humeral and/or a cellular immune response.
A particularly preferred polypeptide of the invention is derived from SEQ ID NO: 6 and is otherwise as defined above.
SEQ ID NOs: 1-30 include antigenic determinants (epitopes) that are as such recognized by antibodies and/or when bound to MHC molecules by T-cell receptors. For the purposes of the present invention, B-cell epitopes (i.e. antibody binding epitopes) are of particular relevance.
It is relatively uncomplicated to identify linear B-cell epitopes—one very simple approach entails that antibodies raised against K. pneumoniae or K. pneumoniae derived proteins disclosed herein are tested for binding to overlapping oligomeric peptides derived from any one of SEQ ID NO: 1-30. Thereby, the regions of the K. pneumoniae polypeptide which are responsible for or contribute to binding to the antibodies can be identified.
Alternatively, or additionally, one can produce mutated versions of the polypeptides of the invention, e.g. version where each single non-alanine residue in any one of SEQ ID NOs: 1-30 are point mutated to alanine—this method also assists in identifying complex assembled B-cell epitopes; this is the case when binding of the same antibody is modified by exchanging amino acids in different areas of the full-length polypeptide.
Also, in silico methods for B-cell epitope prediction can be employed: useful state-of-the-art systems for β-turn prediction is provided in Petersen B et al. (November 2010), Plos One 5(11): e15079; prediction of linear B-cell epitopes, cf: Larsen J E P et al. (April 2006), Immunome Research, 2:2; prediction of solvent exposed amino acids: Petersen B et al (July 2009), BMC Structural Biology, 9:51.
The nucleic acid fragment of the invention referred to above is preferably is a DNA fragment (of a sequence such as SEQ ID NOs: 31-60 and 95-98) or an RNA fragment (of a sequence such as SEQ ID NOs 61-90 and 99-102).

SEQ ID NOs:31-60. Longer fragments are contemplated, i.e. fragments having at least 200, at least 300 at least 400, at least 500, at least 600, at least 700, at least 800, at least 900, at least 1000, at least 1500, at least 2000, at least 2500, at least 3000, at least 3500, and at least 4000 consecutive nucleotides from those of SEQ ID NOs: 31-90 and 95-102 that encompass fragments of such lengths.
In some embodiments the at most 10 consecutive nucleotides referred to in option iii) in the definition of the second aspect of the invention constitute 6, 7, 8, 9 or 10 nucleotides.
The nucleic acid fragment of the invention discussed above typically has a sequence identity with the nucleotide sequence defined for i) or ii) above, which is at least 65%, such as at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, and at least 99%.
The nucleic acid fragment of the invention discussed above may also have a sequence identity with the nucleotide sequence defined for iii) above, which is at least 65%, such as at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, and at least 99%.
The nucleic acid fragment of the invention described above comprises in certain embodiments at least or exactly or at most X distinct nucleic acid sequences each encoding a polypeptide of the invention, where each of said X distinct nucleic acid sequences encodes at least or exactly or at most one immunogenic amino acid sequence present in or derived from any one of SEQ
ID NOs: 1-30 and wherein said X distinct nucleic acid sequences together encode immunogenic amino acid sequences present in or derived from at least or exactly or at most X of SEQ ID NOs: 1-30, 93 or 94, wherein X is an integer selected from 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, and 32. In other words, such a nucleic acid fragment encodes several polypeptides of the invention.
In some embodiments, the X nucleic acid sequences are expressed as separate encoded proteins and in other embodiments as “pearls on a string”, i.e. fused proteins. In some embodiments, immunogenic amino acid sequences from any one of SEQ ID NOs: 1-30, 93 and 94 are only present in one of said X nucleic acid sequences.
It will be understood that the nucleic acid fragments of the invention may be used for both production, carrier and vaccine purposes—the latter will require that the sequences are included in expression vectors that may lead to production of immunogenic proteins in the host animal receiving the vector.
Vectors of the invention fall into several categories discussed infra. One preferred vector of the invention comprises in operable linkage and in the 5′-3′ direction, an expression control region comprising an enhancer/promoter for driving expression of the nucleic acid fragment defined for option i) above, optionally a signal peptide coding sequence, a nucleotide sequence defined for option i), and optionally a terminator. Hence, such a vector constitutes an expression vector useful for effecting production in cells of the polypeptide of the invention. Since the polypeptides of the invention are bacterial of origin, recombinant production is conveniently effected in bacterial host cells, so here it is preferred that the expression control region drives expression in prokaryotic cell such as a bacterium, e.g. in E. coli. However, if the vector is to drive expression in mammalian cell (as would be the case for a DNA vaccine vector), the expression control region should be adapted to this particular use.
At any rate, certain vectors of the invention are capable of autonomous replication.
Also, the vector of the invention may be one that is capable of being integrated into the genome of a host cell—this is particularly useful if the vector is use in the production of stably transformed cells, where the progeny will also include the genetic information introduced via the vector. Alternatively, vectors incapable of being integrated into the genome of a mammalian host cell are useful in e.g. DNA vaccination.
Typically, the vector of the invention is selected from the group consisting of a virus, such as a attenuated virus (which may in itself be useful as a vaccine agent), a bacteriophage, a plasmid, a minichromosome, and a cosmid.
Particularly interesting vectors are viral vectors (in particular those useful as vaccine agents). These may be selected from the group consisting of a retrovirus vector, such as a lentivirus vector, an adenovirus vector, an adeno-associated virus vector, and a pox virus vector. Certain pox virus vectors are preferred, in particular vaccinia virus vectors. A particularly preferred vaccinia virus vector is a modified vaccinia Ankara (MVA) vector.
A more detailed discussion of vectors of the invention is provided in the following:
Polypeptides of the invention may be encoded by a nucleic acid molecule comprised in a vector. A nucleic acid sequence can be “heterologous,” which means that it is in a context foreign to the cell in which the vector is being introduced, which includes a sequence homologous to a sequence in the cell but in a position within the host cell where it is ordinarily not found. Vectors include naked DNAs, RNAs, plasmids, cosmids, viruses (bacteriophage, animal viruses, and plant viruses), and artificial chromosomes (e.g., YACs). One of skill in the art would be well equipped to construct a vector through standard recombinant techniques (for example Sambrook et al, 2001; Ausubel et al, 1996, both incorporated herein by reference). In addition to encoding the polypeptides of this invention, a vector of the present invention may encode polypeptide sequences such as a tag or immunogenicity enhancing peptide (e.g. an immunogenic carrier or a fusion partner that stimulates the immune system, such as a cytokine or active fragment thereof). Useful vectors encoding such fusion proteins include pIN vectors (Inouye et al, 1985), vectors encoding a stretch of histidines, and pGEX vectors, for use in generating glutathione S-transferase (GST) soluble fusion proteins for later purification and separation or cleavage.
Vectors of the invention may be used in a host cell to produce a polypeptide of the invention that may subsequently be purified for administration to a subject or the vector may be purified for direct administration to a subject for expression of the protein in the subject (as is the case when administering a nucleic acid vaccine).
Expression vectors can contain a variety of “control sequences,” which refer to nucleic acid sequences necessary for the transcription and possibly translation of an operably linked coding sequence in a particular host organism. In addition to control sequences that govern transcription and translation, vectors and expression vectors may contain nucleic acid sequences that serve other functions as well and are described infra.
A “promoter” is a control sequence. The promoter is typically a region of a nucleic acid sequence at which initiation and rate of transcription are controlled. It may contain genetic elements at which regulatory proteins and molecules may bind such as RNA polymerase and other transcription factors. The phrases “operatively positioned,” “operatively linked,” “under control,” and “under transcriptional control” mean that a promoter is in a correct functional location and/or orientation in relation to a nucleic acid sequence to control transcriptional initiation and expression of that sequence. A promoter may or may not be used in conjunction with an “enhancer,” which refers to a cis-acting regulatory sequence involved in the transcriptional activation of a nucleic acid sequence.
A promoter may be one naturally associated with a gene or sequence, as may be obtained by isolating the 5′ non-coding sequences located upstream of the coding segment or exon. Such a promoter can be referred to as “endogenous.” Similarly, an enhancer may be one naturally associated with a nucleic acid sequence, located either downstream or upstream of that sequence. Alternatively, certain advantages will be gained by positioning the coding nucleic acid segment under the control of a recombinant or heterologous promoter, which refers to a promoter that is not normally associated with a nucleic acid sequence in its natural environment. A recombinant or heterologous enhancer refers also to an enhancer not normally associated with a nucleic acid sequence in its natural state. Such promoters or enhancers may include promoters or enhancers of other genes, and promoters or enhancers isolated from any other prokaryotic, viral, or eukaryotic cell, and promoters or enhancers not “naturally occurring,” i.e., containing different elements of different transcriptional regulatory regions, and/or mutations that alter expression. In addition to producing nucleic acid sequences of promoters and enhancers synthetically, sequences may be produced using recombinant cloning and/or nucleic acid amplification technology, including PCR™, in connection with the compositions disclosed herein (see U.S. Pat. Nos. 4,683,202, 5,928,906, each incorporated herein by reference).
Naturally, it may be important to employ a promoter and/or enhancer that effectively direct(s) the expression of the DNA segment in the cell type or organism chosen for expression. Those of skill in the art of molecular biology generally know the use of promoters, enhancers, and cell type combinations for protein expression (see Sambrook et al, 2001, incorporated herein by reference). The promoters employed may be constitutive, tissue-specific, or inducible and in certain embodiments may direct high level expression of the introduced DNA segment under specified conditions, such as large-scale production of recombinant proteins or peptides.
Examples of inducible elements, which are regions of a nucleic acid sequence that can be activated in response to a specific stimulus, include but are not limited to Immunoglobulin Heavy Chain (Banerji et al, 1983; Gilles et al, 1983; Grosschedl et al, 1985; Atchinson et al, 1986, 1987; toiler et al, 1987; Weinberger et al, 1984; Kiledjian et al, 1988; Porton et al; 1990), Immunoglobulin Light Chain (Queen et al, 1983; Picard et al, 1984), T Cell Receptor (Luria et al, 1987; Winoto et al, 1989; Redondo et al; 1990), HLA DQα and/or DQβ (Sullivan et al, 1987), β-Interferon (Goodbourn et al, 1986; Fujita et al, 1987; Goodbourn et al, 1988), Interleukin-2 (Greene et al, 1989), Interleukin-2 Receptor (Greene et al, 1989; Lin et al, 1990), MHC Class II 5 (Koch et al, 1989), MHC Class II HLA-DRa (Sherman et al, 1989), (3-Actin (Kawamoto et al, 1988; Ng et al; 1989), Muscle Creatine Kinase (MCK) (Jaynes et al, 1988; Horlick et al, 1989; Johnson et al, 1989), Prealbumin (Transthyretin) (Costa et al, 1988), Elastase I (Omitz et al, 1987), Metallothionein (MTII) (Karin et al, 1987; Culotta et al, 1989), Collagenase (Pinkert et al, 1987; Angel et al, 1987), Albumin (Pinkert et al, 1987; Tranche et al, 1989, 1990), α-Fetoprotein (Godbout et al, 1988; Campere et al, 1989), γ-Globin (Bodine et al, 1987; Perez-Stable et al, 1990),β-Globin (Trudel et al, 1987), c-fos (Cohen et al, 1987), c-HA-ras (Triesman, 1986; Deschamps et al, 1985), Insulin (Edlund et al, 1985), Neural Cell Adhesion Molecule (NCAM) (Hirsh et al, 1990), αI-Antitrypain (Larimer et al, 1990), H2B (TH2B) Histone (Hwang et al, 1990), Mouse and/or Type I Collagen (Ripe et al, 1989), Glucose-Regulated Proteins (GRP94 and GRP78) (Chang et al, 1989), Rat Growth Hormone (Larsen et al, 1986), Human Serum Amyloid A (SAA) (Edbrooke et al, 1989), Troponin I (TN I) (Yutzey et al, 1989), Platelet-Derived Growth Factor (PDGF) (Pech et al, 1989), Duchenne Muscular Dystrophy (Klamut et al, 1990), SV40 (Banerji et al, 1981; Moreau et al, 1981; Sleigh et al, 1985; Firak et al, 1986; Herr et al, 1986; Imbra et al, 1986; Kadesch et al, 1986; Wang et al, 1986; Ondek et al, 1987; Kuhl et al, 1987; Schaffner et al, 1988), Polyoma (Swartzendruber et al, 1975; Vasseur et al, 1980; Katinka et al, 1980, 1981; Tyndell et al, 1981; Dandolo et al, 1983; de Villiers et al, 1984; Hen et al, 1986; Satake et al, 1988; Campbell et al, 1988), Retroviruses (Kriegler et al, 1982, 1983; Levinson et al, 1982; Kriegler et al, 1983, 1984a, b, 1988; Bosze et al, 1986; Miksicek et al, 1986; Celander et al, 1987; Thiesen et al, 1988; Celander et al, 1988; Choi et al, 1988; Reisman et al, 1989), Papilloma Virus (Campo et al, 1983; Lusky et al, 1983; Spandidos and Wilkie, 1983; Spalholz et al, 1985; Lusky et al, 1986; Cripe et al, 1987; Gloss et al, 1987; Hirochika et al, 1987; Stephens et al, 1987), Hepatitis B Virus (Bulla et al, 1986; Jameel et al, 1986; Shaul et al, 1987; Spandau et al, 1988; Vannice et al, 1988), Human Immunodeficiency Virus (Muesing et al, 1987; Hauber et al, 1988; Jakobovits et al, 1988; Feng et al, 1988; Takebe et al, 1988; Rosen et al, 1988; Berkhout et al, 1989; Laspia et al, 1989; Sharp et al, 1989; Braddock et al, 1989), Cytomegalovirus (CMV) IE (Weber et al, 1984; Boshart et al, 1985; Foecking et al, 1986), Gibbon Ape Leukemia Virus (Holbrook et al, 1987; Quinn et al, 1989).
Inducible Elements include, but are not limited to MT II—Phorbol Ester (TFA)/Heavy metals (Palmiter et al, 1982; Haslinger et al, 1985; Searle et al, 1985; Stuart et al, 1985; Imagawa et al, 1987, Karin et al, 1987; Angel et al, 1987b; McNeall et al, 1989); MMTV (mouse mammary tumor virus)—Glucocorticoids (Huang et al, 1981; Lee et al, 1981; Majors et al, 1983; Chandler et al, 1983; Lee et al, 1984; Ponta et al, 1985; Sakai et al, 1988); β-Interferon—poly(rl)x/poly(rc) (Tavernier et al, 1983); Adenovirus 5 E2—EIA (Imperiale et al, 1984); Collagenase—Phorbol Ester (TPA) (Angel et al, 1987a); Stromelysin—Phorbol Ester (TPA) (Angel et al, 1987b); SV40—Phorbol Ester (TPA) (Angel et al, 1987b); Murine MX Gene—Interferon, Newcastle Disease Virus (Hug et al, 1988); GRP78 Gene—A23187 (Resendez et al, 1988); α-2-Macroglobulin—IL-6 (Kunz et al, 1989); Vimentin—Serum (Rittling et al, 1989); MHC Class I Gene H-2Kb—Interferon (Blanar et al, 1989); HSP70—E1A/SV40 Large T Antigen (Taylor et al, 1989, 1990a, 1990b); Proliferin—Phorbol Ester/TPA (Mordacq et al, 1989); Tumor Necrosis Factor—PMA (Hensel et al, 1989); and Thyroid Stimulating Hormonea Gene—Thyroid Hormone (Chatterjee et al, 1989).
Also contemplated as useful in the present invention are the dectin-1 and dectin-2 promoters. Additionally any promoter/enhancer combination (as per the Eukaryotic Promoter Data Base EPDB) could also be used to drive expression of structural genes encoding oligosaccharide processing enzymes, protein folding accessory proteins, selectable marker proteins or a heterologous protein of interest.
The particular promoter that is employed to control the expression of peptide or protein encoding polynucleotide of the invention is not believed to be critical, so long as it is capable of expressing the polynucleotide in a targeted cell, preferably a bacterial cell. Where a human cell is targeted, it is preferable to position the polynucleotide coding region adjacent to and under the control of a promoter that is capable of being expressed in a human cell. Generally speaking, such a promoter might include either a bacterial, human or viral promoter.
In various embodiments, the human cytomegalovirus (CMV) immediate early gene promoter, the SV40 early promoter, and the Rous sarcoma virus long terminal repeat can be used to obtain high level expression of a related polynucleotide to this invention. The use of other viral or mammalian cellular or bacterial phage promoters, which are well known in the art, to achieve expression of polynucleotides is contemplated as well.
In embodiments in which a vector is administered to a subject for expression of the protein, it is contemplated that a desirable promoter for use with the vector is one that is not down-regulated by cytokines or one that is strong enough that even if down-regulated, it produces an effective amount of the protein/polypeptide of the current invention in a subject to elicit an immune response. Non-limiting examples of these are CMV IE and RSV LTR. In other embodiments, a promoter that is up-regulated in the presence of cytokines is employed. The MHC I promoter increases expression in the presence of IFN-γ.
Tissue specific promoters can be used, particularly if expression is in cells in which expression of an antigen is desirable, such as dendritic cells or macrophages. The mammalian MHC I and MHC II promoters are examples of such tissue-specific promoters. 2. Initiation Signals and Internal Ribosome Binding Sites (IRES)
A specific initiation signal also may be required for efficient translation of coding sequences. These signals include the ATG initiation codon or adjacent sequences. Exogenous translational control signals, including the ATG initiation codon, may need to be provided. One of ordinary skill in the art would readily be capable of determining this and providing the necessary signals. It is well known that the initiation codon must be “in-frame” with the reading frame of the desired coding sequence to ensure translation of the entire insert. The exogenous translational control signals and initiation codons can be either natural or synthetic and may be operable in bacteria or mammalian cells. The efficiency of expression may be enhanced by the inclusion of appropriate transcription enhancer elements.
In certain embodiments of the invention, the use of internal ribosome entry sites (IRES) elements are used to create multigene, or polycistronic, messages. IRES elements are able to bypass the ribosome scanning model of 5′ methylated Cap dependent translation and begin translation at internal sites (Pelletier and Sonenberg, 1988). IRES elements from two members of the picornavirus family (polio and encephalomyocarditis) have been described (Pelletier and Sonenberg, 1988), as well an IRES from a mammalian message (Macejak and Sarnow, 1991). IRES elements can be linked to heterologous open reading frames. Multiple open reading frames can be transcribed together, each separated by an IRES, creating polycistronic messages. By virtue of the IRES element, each open reading frame is accessible to ribosomes for efficient translation. Multiple genes can be efficiently expressed using a single promoter/enhancer to transcribe a single message (see U.S. Pat. Nos. 5,925,565 and 5,935,819, herein incorporated by reference).
Vectors can include a multiple cloning site (MCS), which is a nucleic acid region that contains multiple restriction enzyme sites, any of which can be used in conjunction with standard recombinant technology to digest the vector. (See Carbonelli et al, 1999, Levenson et al, 1998, and Cocea, 1997, incorporated herein by reference.) Frequently, a vector is linearized or fragmented using a restriction enzyme that cuts within the MCS to enable exogenous sequences to be ligated to the vector. Techniques involving restriction enzymes and ligation reactions are well known to those of skill in the art of recombinant technology.
Most transcribed eukaryotic RNA molecules will undergo RNA splicing to remove introns from the primary transcripts. If relevant in the context of vectors of the present invention, vectors containing genomic eukaryotic sequences may require donor and/or acceptor splicing sites to ensure proper processing of the transcript for protein expression. (See Chandler et al, 1997, incorporated herein by reference.)
The vectors or constructs of the present invention will generally comprise at least one termination signal. A “termination signal” or “terminator” is comprised of the DNA sequences involved in specific termination of an RNA transcript by an RNA polymerase. Thus, in certain embodiments a termination signal that ends the production of an RNA transcript is contemplated. A terminator may be necessary in vivo to achieve desirable message levels.
In eukaryotic systems, the terminator region may also comprise specific DNA sequences that permit site-specific cleavage of the new transcript so as to expose a polyadenylation site. This signals a specialized endogenous polymerase to add a stretch of about 200 A residues (poly A) to the 3′ end of the transcript. RNA molecules modified with this polyA tail appear to more stable and are translated more efficiently. Thus, in other embodiments involving eukaryotes, it is preferred that that terminator comprises a signal for the cleavage of the RNA, and it is more preferred that the terminator signal promotes polyadenylation of the message.
Terminators contemplated for use in the invention include any known terminator of transcription described herein or known to one of ordinary skill in the art, including but not limited to, for example, the bovine growth hormone terminator or viral termination sequences, such as the SV40 terminator. In certain embodiments, the termination signal may be a lack of transcribable or translatable sequence, such as due to a sequence truncation.
In expression, particularly eukaryotic expression (as is relevant in nucleic acid vaccination), one will typically include a polyadenylation signal to effect proper polyadenylation of the transcript. The nature of the polyadenylation signal is not believed to be crucial to the successful practice of the invention, and/or any such sequence may be employed. Preferred embodiments include the SV40 polyadenylation signal and/or the bovine growth hormone polyadenylation signal, convenient and/or known to function well in various target cells. Polyadenylation may increase the stability of the transcript or may facilitate cytoplasmic transport.
In order to propagate a vector in a host cell, it may contain one or more origins of replication sites (often termed “on”), which is a specific nucleic acid sequence at which replication is initiated. Alternatively an autonomously replicating sequence (ARS) can be employed if the host cell is yeast.
In certain embodiments of the invention, cells containing a nucleic acid construct of the present invention may be identified in vitro or in vivo by encoding a screenable or selectable marker in the expression vector. When transcribed and translated, a marker confers an identifiable change to the cell permitting easy identification of cells containing the expression vector. Generally, a selectable marker is one that confers a property that allows for selection. A positive selectable marker is one in which the presence of the marker allows for its selection, while a negative selectable marker is one in which its presence prevents its selection. An example of a positive selectable marker is a drug resistance marker.
Usually the inclusion of a drug selection marker aids in the cloning and identification of transformants, for example, markers that confer resistance to neomycin, puromycin, hygromycin, DHFR, GPT, zeocin or histidinol are useful selectable markers. In addition to markers conferring a phenotype that allows for the discrimination of transformants based on the implementation of conditions, other types of markers including screenable markers such as GFP for colorimetric analysis. Alternatively, screenable enzymes such as herpes simplex virus thymidine kinase (tk) or chloramphenicol acetyltransferase (CAT) may be utilized. One of skill in the art would also know how to employ immunologic markers that can be used in conjunction with FACS analysis. The marker used is not believed to be important, so long as it is capable of being expressed simultaneously with the nucleic acid encoding a protein of the invention. Further examples of selectable and screenable markers are well known to one of skill in the art.
Transformed cells of the invention are useful as organisms for producing the polypeptide of the invention, but also as simple “containers” of nucleic acids and vectors of the invention.
Certain transformed cells of the invention are capable of replicating the nucleic acid fragment defined for option i) of the second aspect of the invention. Preferred transformed cells of the invention are capable of expressing the nucleic acid fragment defined for option i).
For recombinant production it is convenient, but not a prerequisite that the transformed cell according is prokaryotic, such as a bacterium, but generally both prokaryotic cells and eukaryotic cells may be used.
Suitable prokaryotic cells are bacterial cells selected from the group consisting of Escherichia (such as E. coli), Bacillus (e.g. Bacillus subtilis), Salmonella, and Mycobacterium (preferably non-pathogenic, e.g. M. bovis BCG).
Eukaryotic cells can be in the form of yeasts (such as Saccharomyces cerevisiae) and protozoans. Alternatively, the transformed eukaryotic cells are derived from a multicellular organism such as a fungus, an insect cell, a plant cell, or a mammalian cell.
For production purposes, it is advantageous that the transformed cell of the invention is is stably transformed by having the nucleic acid defined above for option i) stably integrated into its genome, and in certain embodiments it is also preferred that the transformed cell secretes or carries on its surface the polypeptide of the invention, since this facilitates recovery of the polypeptides produced. A particular version of this embodiment is one where the transformed cell is a bacterium and secretion of the polypeptide of the invention is into the periplasmic space.
As noted above, stably transformed cells are preferred—these i.a. allows that cell lines comprised of transformed cells as defined herein may be established—such cell lines are particularly preferred aspects of the invention.
Further details on cells and cell lines are presented in the following:
Suitable cells for recombinant nucleic acid expression of the nucleic acid fragments of the present invention are prokaryotes and eukaryotes. Examples of prokaryotic cells include E. coli; members of the Staphylococcus genus, such as S. epidermidis; members of the Lactobacillus genus, such as L. plantarum; members of the Lactococcus genus, such as L. lactis; members of the Bacillus genus, such as B. subtilis; members of the Corynebacterium genus such as C. glutamicum; and members of the Pseudomonas genus such as P. fluorescens. Examples of eukaryotic cells include mammalian cells; insect cells; yeast cells such as members of the Saccharomyces genus (e.g. S. cerevisiae), members of the Pichia genus (e.g. P. pastoris), members of the Hansenula genus (e.g. H. polymorpha), members of the Kluyveromyces genus (e.g. K. lactis or K. fragilis) and members of the Schizosaccharomyces genus (e.g. S. pombe).
Techniques for recombinant gene production, introduction into a cell, and recombinant gene expression are well known in the art. Examples of such techniques are provided in references such as Ausubel, Current Protocols in Molecular Biology, John Wiley, 1987-2002, and Sambrook et al., Molecular Cloning, A Laboratory Manual, 2 nd Edition, Cold Spring Harbor Laboratory Press, 1989.
As used herein, the terms “cell,” “cell line,” and “cell culture” may be used interchangeably. All of these terms also include their progeny, which is any and all subsequent generations. It is understood that all progeny may not be identical due to deliberate or inadvertent mutations. In the context of expressing a heterologous nucleic acid sequence, “host cell” refers to a prokaryotic or eukaryotic cell, and it includes any transformable organism that is capable of replicating a vector or expressing a heterologous gene encoded by a vector. A host cell can, and has been, used as a recipient for vectors or viruses. A host cell may be “transfected” or “transformed,” which refers to a process by which exogenous nucleic acid, such as a recombinant protein-encoding sequence, is transferred or introduced into the host cell. A transformed cell includes the primary subject cell and its progeny.
Host cells may be derived from prokaryotes or eukaryotes, including bacteria, yeast cells, insect cells, and mammalian cells for replication of the vector or expression of part or all of the nucleic acid sequence(s). Numerous cell lines and cultures are available for use as a host cell, and they can be obtained through the American Type Culture Collection (ATCC), which is an organization that serves as an archive for living cultures and genetic materials (www.atcc.orq) or from other depository institutions such as Deutsche Sammlung vor Micrroorganismen and Zellkulturen (DSM). An appropriate host can be determined by one of skill in the art based on the vector backbone and the desired result. A plasmid or cosmid, for example, can be introduced into a prokaryote host cell for replication of many vectors or expression of encoded proteins. Bacterial cells used as host cells for vector replication and/or expression include Staphylococcus strains, DH5a, JMI 09, and KCB, as well as a number of commercially available bacterial hosts such as SURE® Competent Cells and SOLOP ACK™ Gold Cells (STRATAGENE®, La Jolla, Calif.). Alternatively, bacterial cells such as E. coli LE392 could be used as host cells for phage viruses. Appropriate yeast cells include Saccharomyces cerevisiae, Saccharomyces pombe, and Pichia pastoris.
Examples of eukaryotic host cells for replication and/or expression of a vector include HeLa, Jurkat, 293, Cos, CHO, Saos, and PC12. Many host cells from various cell types and organisms are available and would be known to one of skill in the art. Similarly, a viral vector may be used in conjunction with either a eukaryotic or prokaryotic host cell, particularly one that is permissive for replication or expression of the vector.
Some vectors may employ control sequences that allow it to be replicated and/or expressed in both prokaryotic and eukaryotic cells. One of skill in the art would further understand the conditions under which to incubate all of the above described host cells to maintain them and to permit replication of a vector. Also understood and known are techniques and conditions that would allow large-scale production of vectors, as well as production of the nucleic acids encoded by vectors and their cognate polypeptides, proteins, or peptides.
Numerous expression systems exist that comprise at least a part or all of the compositions discussed above. Prokaryote- and/or eukaryote-based systems can be employed for use with the present invention to produce nucleic acid sequences, or their cognate polypeptides, proteins and peptides. Many such systems are commercially and widely available.
The insect cell/baculovirus system can produce a high level of protein expression of a heterologous nucleic acid segment, such as described in U.S. Pat. Nos. 5,871,986, 4,879,236, both herein incorporated by reference, and which can be bought, for example, under the name MAXBAC® 2.0 from INVITROGEN® and BACPACK™ Baculovirus expression system from CLONTECH®
In addition to the disclosed expression systems of the invention, other examples of expression systems include STRATAGENE®'s COMPLETE CONTROL′ Inducible Mammalian Expression System, which involves a synthetic ecdysone-inducible receptor, or its pET Expression System, an E. coli expression system. Another example of an inducible expression system is available from INVITROGEN®, which carries the T-REX™ (tetracycline-regulated expression) System, an inducible mammalian expression system that uses the full-length CMV promoter. INVITROGEN® also provides a yeast expression system called the Pichia methanolica Expression System, which is designed for high-level production of recombinant proteins in the methylotrophic yeast Pichia methanolica. One of skill in the art would know how to express a vector, such as an expression construct, to produce a nucleic acid sequence or its cognate polypeptide, protein, or peptide.
Nucleic acids used as a template for amplification may be isolated from cells, tissues or other samples according to standard methodologies (Sambrook et al, 2001). In certain embodiments, analysis is performed on whole cell or tissue homogenates or biological fluid samples without substantial purification of the template nucleic acid. The nucleic acid may be genomic DNA or fractionated or whole cell RNA. Where RNA is used, it may be desired to first convert the RNA to a complementary DNA.
The term “primer,” as used herein, is meant to encompass any nucleic acid that is capable of priming the synthesis of a nascent nucleic acid in a template-dependent process. Typically, primers are oligonucleotides from ten to twenty and/or thirty base pairs in length, but longer sequences can be employed. Primers may be provided in double-stranded and/or single-stranded form, although the single-stranded form is preferred.
Pairs of primers designed to selectively hybridize to nucleic acids corresponding to sequences of genes identified herein are contacted with the template nucleic acid under conditions that permit selective hybridization. Depending upon the desired application, high stringency hybridization conditions may be selected that will only allow hybridization to sequences that are completely complementary to the primers. In other embodiments, hybridization may occur under reduced stringency to allow for amplification of nucleic acids containing one or more mismatches with the primer sequences. Once hybridized, the template-primer complex is contacted with one or more enzymes that facilitate template-dependent nucleic acid synthesis. Multiple rounds of amplification, also referred to as “cycles,” are conducted until a sufficient amount of amplification product is produced.
The amplification product may be detected or quantified. In certain applications, the detection may be performed by visual means. Alternatively, the detection may involve indirect identification of the product via chemiluminescence, radioactive scintigraphy of incorporated radiolabel or fluorescent label or even via a system using electrical and/or thermal impulse signals (Bellus, 1994).
A number of template dependent processes are available to amplify the oligonucleotide sequences present in a given template sample. One of the best known amplification methods is the polymerase chain reaction (referred to as PCR™) which is described in detail in U.S. Pat. Nos. 4,683,195, 4,683,202 and 4,800,159, and in Innis et al., 1988, each of which is incorporated herein by reference in their entirety.
Alternative methods for amplification of target nucleic acid sequences that may be used in the practice of the present invention are disclosed in U.S. Pat. Nos. 5,843,650, 5,846,709, 5,846,783, 5,849,546, 5,849,497, 5,849,547, 5,858,652, 5,866,366, 5,916,776, 5,922,574, 5,928,905, 5,928,906, 5,932,451, 5,935,825, 5,939,291 and 5,942,391, GB Application No. 2 202 328, and in PCT Application No. PCT/US89/01025, each of which is incorporated herein by reference in its entirety.
Suitable methods for nucleic acid delivery to effect expression of compositions of the present invention are believed to include virtually any method by which a nucleic acid (e.g., DNA, including viral and nonviral vectors) can be introduced into a cell, a tissue or an organism, as described herein or as would be known to one of ordinary skill in the art. Such methods include, but are not limited to, direct delivery of DNA such as by injection (U.S. Pat. Nos. 5,994,624, 5,981,274, 5,945,100, 5,780,448, 5,736,524, 5,702,932, 5,656,610, 5,589,466 and 5,580,859, each incorporated herein by reference), including microinjection (Harland and Weintraub, 1985; U.S. Pat. No. 5,789,215, incorporated herein by reference); by electroporation (U.S. Pat. No. 5,384,253, incorporated herein by reference); by calcium phosphate precipitation (Graham and Van Der Eb, 1973; Chen and Okayama, 1987; Rippe et al., 1990); by using DEAE dextran followed by polyethylene glycol (Gopal, 1985); by direct sonic loading (Fechheimer et al, 1987); by liposome mediated transfection (Nicolau and Sene, 1982; Fraley et al, 1979; Nicolau et al, 1987; Wong et al, 1980; Kaneda et al, 1989; Kato et al, 1991); by microprojectile bombardment (PCT Application Nos. WO 94/09699 and 95/06128; U.S. Pat. Nos. 5,610,042; 5,322,783 5,563,055, 5,550,318, 5,538,877 and 5,538,880, and each incorporated herein by reference); by agitation with silicon carbide fibers (Kaeppler et al, 1990; U.S. Pat. Nos. 5,302,523 and 5,464,765, each incorporated herein by reference); by Agrobacterium mediated transformation (U.S. Pat. Nos. 5,591,616 and 5,563,055, each incorporated herein by reference); or by PEG mediated transformation of protoplasts (Omirulleh et al, 1993; U.S. Pat. Nos. 4,684,611 and 4,952,500, each incorporated herein by reference); by desiccation/inhibition mediated DNA uptake (Potrykus et al, 1985). Through the application of techniques such as these, organelle(s), cell(s), tissue(s) or organism(s) may be stably or transiently transformed.
The Antibodies of the Invention—and their Production/Isolation
Antibodies directed against the proteins of the invention are useful for affinity chromatography, immunoassays, and for distinguishing/identifying Klebsiella proteins as well as for passive immunisation and therapy.
Antibodies to the proteins of the invention, both polyclonal and monoclonal, may be prepared by conventional methods. In general, the protein is first used to immunize a suitable animal, preferably a mouse, rat, rabbit or goat. Rabbits and goats are preferred for the preparation of polyclonal sera due to the volume of serum obtainable, and the availability of labeled anti-rabbit and anti-goat antibodies. Immunization is generally performed by mixing or emulsifying the protein in saline, preferably in an adjuvant such as Freund's complete adjuvant, and injecting the mixture or emulsion parenterally (generally subcutaneously or intramuscularly). A dose of 50-200 μg/injection is typically sufficient. Immunization is generally boosted 2-6 weeks later with one or more injections of the protein in saline, preferably using Freund's incomplete adjuvant. One may alternatively generate antibodies by in vitro immunization using methods known in the art, which for the purposes of this invention is considered equivalent to in vivo immunization. Polyclonal antiserum is obtained by bleeding the immunized animal into a glass or plastic container, incubating the blood at 25 C for one hour, followed by incubating at 4 C for 2-18 hours. The serum is recovered by centrifugation (eg. 1,000 g for 10 minutes). About 20-50 ml per bleed may be obtained from rabbits.
Monoclonal antibodies are prepared using the standard method of Kohler & Milstein [Nature (1975) 256: 495-96], or a modification thereof. Typically, a mouse or rat is immunized as described above. However, rather than bleeding the animal to extract serum, the spleen (and optionally several large lymph nodes) is removed and dissociated into single cells. If desired, the spleen cells may be screened (after removal of nonspecifically adherent cells) by applying a cell suspension to a plate or well coated with the protein antigen. B-cells expressing membrane-bound immunoglobulin specific for the antigen bind to the plate, and are not rinsed away with the rest of the suspension. Resulting B-cells, or all dissociated spleen cells, are then induced to fuse with myeloma cells to form hybridomas, and are cultured in a selective I aedium (elg. hypexanthine, aminopterin, thymidine medium,“HAT”). The resulting hybridomas are plated by limiting dilution, and are assayed for production of antibodies, which bind specifically to the immunizing antigen (and which do not bind to unrelated antigens). The selected MAb-secreting hybridomas are then cultured either in vitro (eg. in tissue culture bottles or hollow fiber reactors), or in vivo (as ascites in mice).
If desired, the antibodies (whether polyclonal or monoclonal) may be labeled using conventional techniques. Suitable labels include fluorophores, chromophores, radioactive atoms (particularly 32p and 1251), electron-dense reagents, enzymes, and ligands having specific binding partners. Enzymes are typically detected by their activity. For example, horseradish peroxidase is usually detected by its ability to convert 3,3′, 5,5′-tetramethylbenzidine (TMB) to a blue pigment, quantifiable with a spectrophotometer. “Specific binding partner” refers to a protein capable of binding a ligand molecule with high specificity, as for example in the case of an antigen and a monoclonal antibody specific therefor. Other specific binding partners include biotin and avidin or streptavidin, IgG and protein A, and the numerous receptor-ligand couples known in the art. It should be understood that the above description is not meant to categorize the various labels into distinct classes, as the same label may serve in several different modes. For example, 1151 may serve as a radioactive label or as an electron-dense reagent. HRP may serve as enzyme or as antigen for a MAb. Further, one may combine various labels for desired effect. For example, MAbs and avidin also require labels in the practice of this invention: thus, one might label a MAb with biotin, and detect its presence with avidin labeled with, 1251, or with an anti-biotin MAb labeled with HRP. Other permutations and possibilities will be readily apparent to those of ordinary skill in the art, and are considered as equivalents within the scope of the instant invention.
According to the invention, the isolated monoclonal antibody or antibody analogue is preferably a monoclonal antibody selected from a multi-domain antibody such as a murine antibody, a chimeric antibody such as a humanized antibody, a fully human antibody, and single-domain antibody of a llama or a camel, or which is an antibody analogue selected from a fragment of an antibody such as an Fab or an F(ab′)2, an scFV; cf. also the definition of the term “antibody” presented above.
Pharmaceutical compositions, in particular vaccines, according to the invention may either be prophylactic (ie. to prevent infection) or therapeutic (ie, to treat disease after infection).
Such vaccines comprise immunising antigen(s), immunogen(s), polypeptide(s), protein(s) or nucleic acid(s), usually in combination with “pharmaceutically acceptable carriers”, which include any carrier that does not itself induce the production of antibodies harmful to the individual receiving the composition.
In some embodiments of the invention, the pharmaceutical compositions such as vaccines include merely one single antigen, immunogen, polypeptide, protein, nucleic acid or vector of the invention, but in other embodiments, the pharmaceutical compositions comprise “cocktails” of the antigens or of the immunogens or of the polypeptides or of the protein or of the nucleic acids or of the vectors of the invention.
In particularly interesting embodiments, the pharmaceutical composition is an MVA vector mentioned herein, which encodes and can effect expression of at least 2 nucleic acid fragments of the invention.
Another interesting embodiment of a pharmaceutical composition comprises RNA as the active principle, i.e. at least one mRNA encoding a polypeptide of the invention.
An embodiment of a pharmaceutical composition of the invention comprises Y or at least Y or at most Y distinct polypeptides of the invention described above, where each of said Y or at least Y or at most Y distinct polypeptides comprises an immunogenic amino acid sequence present in or derived from any one of SEQ ID NOs: 1-30 and wherein said Y or at least Y or at most Y distinct polypeptides together comprise immunogenic amino acid sequences present in or derived from Y or at least Y or at most Y of SEQ NOs: 1-30, 93 or 94, wherein Y is an integer selected from 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, and 32.
Another embodiment of the pharmaceutical composition of the invention comprises Z or at least Z or at most Z distinct nucleic acid molecules (such as DNA and RNA) each encoding a polypeptide of the invention, where each of said Z or at least Z or at most Z distinct nucleic acid molecules encodes an immunogenic amino acid sequence present in or derived from any one of SEQ ID NOs: 1-30, 93, or 94 and wherein said at Z or least Z distinct nucleic acid molecules together encode immunogenic amino acid sequences present in or derived from Z or at least Z or at most Z of SEQ ID NOs: 1-30, 93, or 94, wherein Z is an integer selected from 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, and 32.
Suitable carriers are typically large, slowly metabolized macromolecules such as proteins, polysaccharides, polylactic acids, polyglycolic acids, polymeric amino acids, amino acid copolymers, lipid aggregates (such as oil droplets or liposomes), and inactive virus particles.
Such carriers are well known to those of ordinary skill in the art. Additionally, these carriers may function as immunostimulating agents (“adjuvants”). Furthermore, the antigen or immunogen may be conjugated to a bacterial toxoid, such as a toxoid from diphtheria, tetanus, cholera, H. pylori, etc. pathogen, cf. the description of immunogenic carriers supra.
The pharmaceutical compositions of the invention thus typically contain an immunological adjuvant, which is commonly an aluminium based adjuvant or one of the other adjuvants described in the following:
Preferred adjuvants to enhance effectiveness of the composition include, but are not limited to: (1) aluminum salts (alum), such as aluminum hydroxide, aluminum phosphate, aluminum sulfate, etc; (2) oil-in-water emulsion formulations (with or without other specific immunostimulating agents such as muramyl peptides (see below) or bacterial cell wall components), such as for example (a) MF59 (WO 90/14837; Chapter 10 in Vaccine design: the subunit and adjuvant approach, eds. Powell & Newman, Plenum Press 1995), containing 5% Squalene, 0.5% Tween 80, and 0.5% Span 85 (optionally containing various amounts of MTP-PE (see below), although not required) formulated into submicron particles using a microfluidizer such as Model 110Y microfluidizer (Microfluidics, Newton, Mass.), (b) SAF, containing 10% Squalane, 0.4% Tween 80, 5% pluronic-blocked polymer L121, and thr-MDP (see below) either microfluidized into a submicron emulsion or vortexed to generate a larger particle size emulsion, and (c) Ribi adjuvant system (RAS), (Ribi Immunochem, Hamilton, Mont.) containing 2% Squalene, 0.2% Tween 80, and one or more bacterial cell wall components from the group consisting of monophosphoryl lipid A (MPL), trehalose dimycolate (TDM), and cell wall skeleton (CWS), preferably MPL+CWS (Detox™); (3) saponin adjuvants such as Stimulon™ (Cambridge Bioscience, Worcester, Mass.) may be used or particles generated therefrom such as ISCOMs (immunostimulating complexes); (4) Complete Freund's Adjuvant (CFA) and Incomplete Freund's Adjuvant (IFA); (5) cytokines, such as interleukins (eg. IL-1, IL-2, IL-4, IL-5, IL-6, IL-7, IL-12, etc.), interferons (eg. gamma interferon), macrophage colony stimulating factor (M-CSF), tumor necrosis factor (TNF), etc.; and (6) other substances that act as immunostimulating agents to enhance the effectiveness of the composition. Alum and MF59™ adjuvants are preferred.
As mentioned above, muramyl peptides include, but are not limited to, N-acetyl-muramyl-L-threonyl-D-isoglutamine (thr-MDP), N-acetyl-normuramyl-L-alanyl-D-isoglutamine (nor-MDP), N-acetylmuramyl-L-alanyl-D-isoglutaminyl-L-alanine-2″-2′-dipalmitoyl-sn-glycero-3-hydroxyphosphoryloxy)-ethylamine (MTP-PE), etc.
The immunogenic compositions (eg. the immunising antigen or immunogen or polypeptide or protein or nucleic acid, pharmaceutically acceptable carrier, and adjuvant) typically will contain diluents, such as water, saline, glycerol, ethanol, etc. Additionally, auxiliary substances, such as wetting or emulsifying agents, pH buffering substances, and the like, may be present in such vehicles.
Typically, the immunogenic compositions are prepared as injectables, either as liquid solutions or suspensions; solid forms suitable for solution in, or suspension in, liquid vehicles prior to injection may also be prepared. The preparation also may be emulsified or encapsulated in liposomes for enhanced adjuvant effect, as discussed above under pharmaceutically acceptable carriers.
Immunogenic compositions used as vaccines comprise an immunologically effective amount of the antigenic or immunogenic polypeptides, as well as any other of the above-mentioned components, as needed. By “immunollogically effective amount”, it is meant that the administration of that amount to an individual, either in a single dose or as part of a series, is effective for treatment or prevention. This amount varies depending upon the health and physical condition of the individual to be treated, the taxonomic group of individual to be treated (eg. nonhuman primate, primate, etc.), the capacity of the individual's immune system to synthesize antibodies or generally mount an immune response, the degree of protection desired, the formulation of the vaccine, the treating doctor's assessment of the medical situation, and other relevant factors. It is expected that the amount will fall in a relatively broad range that can be determined through routine trials. However, for the purposes of protein vaccination, the amount administered per immunization is typically in the range between 0.5 μg and 500 mg (however, often not higher than 5,000 μg), and very often in the range between 10 and 200 μg.
The immunogenic compositions are conventionally administered parenterally, eg, by injection, either subcutaneously, intramuscularly, or transdermally/transcutaneously (eg. WO98/20734). Additional formulations suitable for other modes of administration include oral and pulmonary formulations, suppositories, and transdermal applications. In the case of nucleic acid vaccination, also the intravenous or intraarterial routes may be applicable.
Dosage treatment may be a single dose schedule or a multiple dose schedule. The vaccine may be administered in conjunction with other immunoregulatory agents.
As an alternative to protein-based vaccines, DNA vaccination (also termed nucleic acid vaccination or gene vaccination) may be used [eg. Robinson & Torres (1997) Seminars in Immunol 9: 271-283; Donnelly et al. (1997) Avnu Rev Innnunol 15: 617-648; later herein].
A further aspect of the invention is as mentioned above the recognition that combination vaccines can be provided, wherein 2 or more antigens disclosed herein are combined to enhance the immune response by the vaccinated animal, including to optimize initial immune response and duration of immunity. For the purposes of this aspect of the invention, multiple antigenic fragments derived from the same, longer protein can also be used, such as the use of a combination of different lengths of polypeptide sequence fragments from one protein.

The method of the sixth aspect of the invention generally relates to induction of immunity and as such also entails method that relate to treatment, prophylaxis and amelioration of disease.
When immunization methods entail that a polypeptide of the invention or a composition comprising such a polypeptide is administered the animal (e.g. the human) typically receives between 0.5 and 5,000 μg of the polypeptide of the invention per administration.
In preferred embodiments of the sixth aspect, the immunization scheme includes that the animal (e.g. the human) receives a priming administration and one or more booster administrations.
Preferred embodiments of the 6th aspect of the invention comprise that the administration is for the purpose of inducing protective immunity against K. pneumoniae. In this embodiment it is particularly preferred that the protective immunity is effective in reducing the risk of attracting infection with K. pneumoniae or is effective in treating or ameliorating infection with K. pneumoniae.
As mentioned herein, the preferred vaccines of the invention induce humoral immunity, so it is preferred that the administration is for the purpose of inducing antibodies specific for K. pneumoniae and wherein said antibodies or B-lymphocytes producing said antibodies are subsequently recovered from the animal.
But, as also mentioned the method of the 6th aspect may also be useful in antibody production, so in other embodiments the administration is for the purpose of inducing antibodies specific for K. pneumoniae and wherein B-lymphocytes producing said antibodies are subsequently recovered from the animal and used for preparation of monoclonal antibodies.
Pharmaceutical compositions can as mentioned above comprise polypeptides, antibodies, or nucleic acids of the invention. The pharmaceutical compositions will comprise a therapeutically effective amount thereof.
The term “therapeutically effective amount” or “prophylactically effective amount” as used herein refers to an amount of a therapeutic agent to treat, ameliorate, or prevent a desired disease or condition, or to exhibit a detectable therapeutic or preventative effect. The effect can be detected by, for example, chemical markers or antigen levels. Therapeutic effects also include reduction in physical symptoms, such as decreased body temperature. The precise effective amount for a subject will depend upon the subject's size and health, the nature and extent of the condition, and the therapeutics or combination of therapeutics selected for administration. Thus, it is not useful to specify an exact effective amount in advance. Reference is however made to the ranges for dosages of immunologically effective amounts of polypeptides, cf. above.
However, the effective amount for a given situation can be determined by routine experimentation and is within the judgement of the clinician.
For purposes of the present invention, an effective dose will be from about 0.01 mg/kg to 50 mg/kg or 0.05 mg/kg to about 10 mg/kg of the DNA constructs in the individual to which it is administered.
A pharmaceutical composition can also contain a pharmaceutically acceptable carrier. The term “pharmaceutically acceptable carrier” refers to a carrier for administration of a therapeutic agent, such as antibodies or a polypeptide, genes, and other therapeutic agents. The term refers to any pharmaceutical carrier that does not itself induce the production of antibodies harmful to the individual receiving the composition, and which may be administered without undue toxicity. Suitable carriers may be large, slowly metabolized macromolecules such as proteins, polysaccharides, polylactic acids, polyglycolic acids, polymeric amino acids, amino acid copolymers, and inactive virus particles. Such carriers are well known to those of ordinary skill in the art.
Pharmaceutically acceptable salts can be used therein, for example, mineral acid salts such as hydrochlorides, hydrobromides, phosphates, sulfates, and the like; and the salts of organic acids such as acetates, propionates, malonates, benzoates, and the like. A thorough discussion of pharmaceutically acceptable excipients is available in Remington's Pharmaceutical Sciences (Mack Pub. Co., N. J. 1991).
Pharmaceutically acceptable carriers in therapeutic compositions may contain liquids such as water, saline, glycerol and ethanol. Additionally, auxiliary substances, such as wetting or emulsifying agents, pH buffering substances, and the like, may be present in such vehicles. Typically, the therapeutic compositions are prepared as injectables, either as liquid solutions or suspensions; solid forms suitable for solution in, or suspension in, liquid vehicles prior to injection may also be prepared. Liposomes are included within the definition of a pharmaceutically acceptable carrier.
As is apparent from the claims, the invention also relates to related embodiments to the treatment and prophylaxis disclosed herein: the invention also includes embodiments where
The sequence listing included sets forth the sequences of polypeptides and nucleic acids of the present invention. For easy reference, the sequences are presented in the following:
The polypeptides of the invention have or derive from the following amino acid sequences:
The nucleic acid fragments of the present invention have or derive from the following sequences:
The polypeptides of the invention can also be designated as follows:
When designating a fragment of one of these proteins, this is done using the nomenclature KP1_XXXX-A-p1-p2, where XXXX is any of the 4 digit numbers following “KP1” in the table above, and p1 and p2 are the start and end amino acids relative to the entire sequence of the protein. For instance KP1_1891-50-200 is the fragment of KP1_1891 that has the amino acid sequence defined by residues 50 to 200 of KP1_1891, i.e. a (poly)peptide having the amino acid sequence of SEQ ID NO: 30, residues 50-200.
1. CHALLENGE STUDY (Klebsiella pneumonia—Intranasal (IN) Model):
A total 6 experiments was carried out. Only experiment 2 utilised the IP model whereas the remaining experiments utilised the IN model.
A number of the tested proteins proved insoluble in saline. Instead they were solubilized in 4 M urea to avoid precipitation before adding aluminum hydroxide. After adding aluminum hydroxide the urea is removed completely. The remaining proteins are solubilized in physiological saline.
The protocol for immunization is described below.
The following table A lists the immunogens used in each of the immunization studies in 6 different experiments as well as the p-value for the survival in each group when compared to mice vaccinated with phosphate buffered saline alone.
