Description

FIELD OF THE INVENTION

The present invention relates to novel filariid nematode protease genes, proteins encoded by such genes, antibodies raised against such proteins, and protease inhibitors produced using such proteins. Particular proteases of the present invention include cysteine proteases. The present invention also includes therapeutic compositions comprising such nucleic acid molecules, proteins, antibodies and inhibitors, as well as their use to protect animals from disease caused by helminth parasites, such as by tissue-migrating helminths, including Dirofilaria and Onchocerca.

BACKGROUND OF THE INVENTION

Parasite infections in animals, including humans, are typically treated by chemical drugs, because there are essentially no efficacious vaccines available. One disadvantage with chemical drugs is that they must be administered often. For example, dogs susceptible to heartworm are typically treated monthly to maintain protective drug levels. Repeated administration of drugs to treat parasite infections, however, often leads to the development of resistant strains that no longer respond to treatment. Furthermore, many of the chemical drugs are harmful to the animals being treated, and as larger doses become required due to the build up of resistance, the side effects become even greater.

It is particularly difficult to develop vaccines against parasite infections both because of the complexity of the parasite's life cycle and because, while administration of parasites or parasite antigens can lead to the production of a significant antibody response, the immune response is typically not sufficient to protect the animal against infection.

As for most parasites, the life cycle of Dirofilaria immitis , the helminth that causes heartworm, includes a variety of life forms, each of which presents different targets, and challenges, for immunization. Adult forms of the parasite are quite large and preferentially inhabit the heart and pulmonary arteries of an animal. Sexually mature adults, after mating, produce microfilariae which traverse capillary beds and circulate in the vascular system. The microfilariae are ingested by female mosquitos during blood feeding on an infected dog, subsequent development of the microfilariae into two larval stages (L1 and L2) occurs in the mosquito. The microfilariae go through and finally become mature third stage larvae (L3) which can then be transmitted back to a dog through the bite of the mosquito. It is this L3 stage, therefore, that accounts for the initial infection. As early as three days after infection; the L3 molt to the fourth larval (L4) stage, and subsequently to the fifth stage, or immature adults. The immature adults migrate to the heart and pulmonary arteries, where they mature and reproduce, thus producing the microfilariae in the blood. “Occult” infection with heartworm in dogs is defined as an infection in which no microfilariae can be detected, but the existence of adult heartworms can be determined through thoracic examination.

Both the molting process and tissue migration are likely to involve the action of one or more enzymes, including proteases. Although protease activity has been identified in a number of parasites (including in larval excretory-secretory products) as well as in mammals, there has been no identification of a cysteine protease gene in any filariid nematode.

Cysteine protease genes have been isolated from several mammalian sources and from the nematodes Haemonchus contortus (e.g., Pratt et al., 1992 , Mol. Biochem. Parasitol . 51, 209-218) and Caenorhabditis elegans (Ray et al., 1992 , Mol. Biochem. Parasitol . 51, 239-250). In addition, consensus sequences, particularly around the active sites, have also been identified for serine and cysteine proteases; see, for example, Sakanari et al., 1989 , Proc. Natl. Acad. Sci. USA 86, 4863-4867. The determination of these sequences, however, does not necessarily predict that the cloning of novel cysteine protease genes will be straight-forward, particularly since the sequences shared by different cysteine proteases are such that probes and primers based on the consensus sequences are highly degenerative.

Heartworm not only is a major problem in dogs, which typically are unable to develop immunity after infection (i.e., dogs can become reinfected even after being cured by chemotherapy), but is also becoming increasingly widespread in other companion animals, such as cats and ferrets. Heartworm infections have also been reported in humans. Other parasite infections are also widespread, and all require better treatment, including preventative vaccine programs and/or targeted drug therapies.

SUMMARY OF THE INVENTION

One embodiment of the present invention relates to an isolated filariid nematode larval nucleic acid molecule that hybridizes, under stringent hybridization conditions, with a Dirofilaria immitis L3 larval cysteine protease gene and/or an Onchocerca volvulus L3 larval cysteine protease gene.

The present invention also includes inhibitors of cysteine protease activity as well as antibodies that recognize (i.e., selectively bind to) a filariid nematode cysteine protease protein and/or mimetope thereof of the present invention. Also included are methods to produce such proteins, inhibitors and antibodies of the present invention.

Yet another embodiment of the present invention is a therapeutic composition capable of protecting an animal from disease caused by a parasitic helminth. Such a therapeutic composition comprises at least one of the following protective compounds: an isolated parasitic filariid nematode larval nucleic acid molecule that hybridizes under stringent hybridization conditions with a Dirofilaria immitis L3 larval cysteine protease gene and/or an Onchocerca volvulus L3 larval cysteine protease gene; an isolated filariid nematode larval cysteine protease protein or a mimetope thereof; an isolated antibody that selectively binds to a filariid nematode L3 larval cysteine protease protein; and an inhibitor of cysteine protease activity identified by its ability to inhibit filariid nematode L3 larval cysteine protease activity.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides for filariid nematode L3 larval cysteine protease proteins and nucleic acid molecules, as well as, antibodies directed against filariid nematode L3 larval cysteine protease proteins. Also included in the present invention is the use of these proteins, nucleic acid molecules and antibodies as therapeutic compositions to treat parasitic helminth diseases as well as in other applications, such as those disclosed below.

One embodiment of the present invention is an isolated filariid nematode L3 larval cysteine protease protein. A cysteine protease is referred to herein as “CP.” A CP that can be found in third stage larvae (L3) is referred to herein as L3 larval CP. That such a protease is referred to as an L3 larval protease does not preclude that protease from also being present in other life stages of a helminth. Indeed, D. immitis L3 CP is also found in fourth stage larvae (L4), suggesting that L3 CP's of the present invention, in general, can also be found in L4. Furthermore, the inventors discovered that immune dog serum prepared as disclosed in PCT Patent Publication No. WO 92/13560, published Aug. 20, 1992, selectively binds to larval CP's of the present invention, a finding that enabled isolation of the first filariid nematode CP nucleic acid molecule.

According to the present invention, an isolated, or biologically pure, protein, is a protein that has been removed from its natural milieu. As such, “isolated” and “biologically pure” do not necessarily reflect the extent to which the protein has been purified. An isolated CP protein of the present invention can be obtained from its natural source, can be produced using recombinant DNA technology or can be produced by chemical synthesis. As used herein, an isolated CP protein of the present invention can be a full-length protein or any homologue of such a protein. Examples of CP homologues include CP proteins in which amino acids have been deleted (e.g., a truncated version of the protein, such as a peptide), inserted, inverted, substituted and/or derivatized (e.g., by glycosylation, phosphorylation, acetylation, myristoylation, prenylation, palmitoylation, amidation and/or addition of glycerophosphatidyl inositol) such that the homologue includes at least one epitope capable of eliciting an immune response against a CP protein of the present invention. That is, when the homologue is administered to an animal as an immunogen, using techniques known to those skilled in the art, the animal will produce a humoral and/or cellular immune response against at least one epitope of a CP protein of the present invention. The ability of a protein to effect an immune response, can be measured using techniques known to those skilled in the art.

Homologues of CP proteins of the present invention can be the result of natural allelic variation or natural mutation. CP protein homologues of the present invention can also be produced using techniques known in the art including, but not limited to, direct modifications to the protein or modifications to the gene encoding the protein using, for example, classic or recombinant DNA techniques to effect random or targeted mutagenesis. Isolated proteins of the present invention, including homologues, can be identified in a straight-forward manner by the proteins' ability to elicit an immune response against filariid nematode CP proteins.

CP proteins of the present invention, including homologues of the full-length protein, have the further characteristic of being encoded by nucleic acid molecules that hybridize under stringent hybridization conditions to at least one of the following genes: (a gene encoding a Dirofilaria immitis L3 cysteine protease protein (i.e., a D. immitis CP gene); and (b) a gene encoding an Onchocerca volvulus L3 cysteine protease protein (i.e., an O. volvulus CP gene). It is to be noted that the term “a” or “an” entity refers to one or more of that entity; for example, a gene refers to one or more genes or at least one gene. As such, the terms “a” (or “an”), “one or more” and “at least one” can be used interchangeably herein. It is also to be noted that the terms “comprising”, “including”, and “having” can be used interchangeably.

As used herein, stringent hybridization conditions refer to standard hybridization conditions under which nucleic acid molecules, including oligonucleotides, are used to identify molecules having similar nucleic acid sequences. Such standard conditions are disclosed, for example, in Sambrook et al., 1989 , Molecular Cloning: A Laboratory Manual , Cold Spring Harbor Labs Press. Examples of such conditions are provided in the Examples section of the present application. Stringent hybridization conditions typically permit isolation of nucleic acid molecules having at least about 70% nucleic acid sequence identity with the nucleic acid molecule being used as a probe in the hybridization reaction. Formulae to calculate the appropriate hybridization and wash conditions to achieve hybridization permitting 30% or less mis-match between two nucleic acid molecules are disclosed, for example, in Meinkoth et al, 1984 , Anal. Biochem 138, 267-284; Meinkoth et al, ibid, is incorporated by reference herein in its entirety.

As used herein, a D. immitis CP gene includes all nucleic acid sequences related to a natural D. immitis CP gene such as regulatory regions that control production of the D. immitis CP protein encoded by that gene (such as, but not limited to, transcription, translation or post-translation control regions) as well as the coding region itself. In one embodiment, a D. immitis CP gene includes the nucleic acid sequence SEQ ID NO:1 and/or SEQ ID NO:26. Nucleic acid sequence SEQ ID NO:1 represents the deduced sequence of a cDNA (complementary DNA) nucleic acid molecule denoted herein as nDiCP 1298 , the production of which is disclosed in the Examples. The complement of SEQ ID NO:1 (represented herein by SEQ ID NO:26) refers to the nucleic acid sequence of the strand complementary to the strand having SEQ ID NO:1, which can easily be determined by those skilled in the art. Likewise, a nucleic acid sequence complement of any nucleic acid sequence of the present invention refers to the nucleic acid sequence of the nucleic acid strand that is complementary to (i.e., can form a double helix with) the strand for which the sequence is cited. It should be noted that since nucleic acid sequencing technology is not entirely error-free, SEQ ID NO:1 (as well as other nucleic acid and protein sequences presented herein), at best, represents an apparent nucleic acid sequence of the nucleic acid molecule encoding a D. immitis CP protein of the present invention. In another embodiment, a D. immitis CP gene includes the nucleic acid sequence SEQ ID NO:32 and/or SEQ ID NO:35. Nucleic acid SEQ ID NO:32 represents the deduced nucleic acid sequence of the coding strand of nDiCP 1304 , and SEQ ID NO:35 is the sequence of the complementary strand of nDiCP 1304 .

In another embodiment, a D. immitis CP gene can be an allelic variant that includes a similar but not identical sequence to SEQ ID NO:1 and/or SEQ ID NO:26. An allelic variant of a D. immitis CP gene including SEQ ID NO:1 and/or SEQ ID NO:26 is a gene that occurs at essentially the same locus (or loci) in the genome as the gene including SEQ ID NO:1 and/or SEQ ID NO:26, but which, due to natural variations caused by, for example, mutation or recombination, has a similar but not identical sequence. Allelic variants typically encode proteins having similar activity to that of the protein encoded by the gene to which they are being compared. Allelic variants can also comprise alterations in the 5′ or 3′ untranslated regions of the gene (e.g., in regulatory control regions). Allelic variants are well known to those skilled in the art and would be expected to be found within a given parasitic helminth since the genome is diploid and/or among a group of two or more filariid nematodes. In another embodiment, a D. immitis CP gene can be an allelic variant that includes a similar but not identical sequence to SEQ ID NO:32 and/or SEQ ID NO:35.

Similarly, an O. volvulus CP gene includes all nucleic acid sequences related to a natural O. volvulus CP gene such as regulatory regions that control production of the O. volvulus CP protein encoded by that gene as well as the coding region itself. In one embodiment, an O. volvulus CP gene includes the nucleic acid sequence SEQ ID NO:5, SEQ ID NO:14, SEQ ID NO:28 and/or SEQ ID NO:30. Nucleic acid sequence SEQ ID NO:5 represents the deduced sequence of a cDNA (complementary DNA) nucleic acid molecule denoted herein as nOvCP 291 , the production of which is disclosed in the Examples. The complement of SEQ ID NO:5 is referred to herein as SEQ ID NO:28. Nucleic acid sequence SEQ ID NO: 14 represents the deduced sequence of a PCR nucleic acid molecule denoted herein as nOvCP 1306 , the production of which is disclosed in the Examples. The complement of SEQ ID NO:14 is referred to herein as SEQ ID NO:30. In another embodiment, an O. volvulus CP gene can be an allelic variant that includes a similar but not identical sequence to SEQ ID NO:5, SEQ ID NO:14, SEQ ID NO:28 and/or SEQ ID NO:30.

The minimal size of a CP protein homologue of the present invention is a size sufficient to be encoded by a nucleic acid molecule capable of forming a stable hybrid with the complementary sequence of a nucleic acid molecule encoding the corresponding natural protein. As such, the size of the nucleic acid molecule encoding such a protein homologue is dependent on nucleic acid composition and percent homology between the nucleic acid molecule and complementary sequence as well as upon hybridization conditions per se (e.g., temperature, salt concentration, and formamide concentration). It should also be noted that the extent of homology required to form a stable hybrid can vary depending on whether the homologous sequences are interspersed throughout the nucleic acid molecules or are clustered (i.e., localized) in distinct regions on the nucleic acid molecules. The minimal size of such nucleic acid molecules is typically at least about 12 to about 15 nucleotides in length if the nucleic acid molecules are GC-rich and at least about 15 to about 17 bases in length if they are AT-rich.

As such, the minimal size of a nucleic acid molecule used to encode a CP protein homologue of the present invention is from about 12 to about 18 nucleotides in length. There is no limit, other than a practical limit, on the maximal size of such a nucleic acid molecule in that the nucleic acid molecule can include a portion of a gene, an entire gene, or multiple genes, or portions thereof. Similarly, the minimal size of a CP protein homologue of the present invention is from about 4 to about 6 amino acids in length, with preferred sizes depending on whether a full-length, fusion, multivalent, or functional portions of such proteins are desired.

Protein homologues of the present invention preferably are capable of eliciting an immune response against a filariid nematode CP protein; of selectively binding to immune serum using techniques as disclosed in PCT Patent Publication No. WO 92/13560 (ibid.); and/or of having cysteine protease activity. The minimum size of a protein capable of eliciting an immune response is a minimum size sufficient to form an epitope, a size that typically is at least from about 5 to about 9 amino acids. As is appreciated by those skilled in the art, an epitope can include amino acids that naturally are contiguous to each other as well as amino acids that, due to the tertiary structure of the natural protein, are in sufficiently close proximity to form an epitope. Methods to measure an immune response or cysteine protease activity are known to those of skill in the art.

Any filariid nematode CP protein is a suitable CP protein of the present invention. Suitable filariid nematodes from which to isolate CP proteins (including isolation of the natural protein or production of the protein by recombinant or synthetic techniques) include, but are not limited to, filariid nematodes of the genera Dirofilaria, Onchocerca, Acanthocheilonema, Brugia, Dipetalonema, Loa, Parafilaria, Setaria, Stephanofilaria and Wuchereria. Preferred filariid nematodes include nematodes of the genera Dirofilaria and Onchocerca, with D. immitis , the parasite that causes heartworm, and O. volvulus , the parasite that causes onchocerciasis, being more preferred.

A preferred filariid nematode CP protein of the present invention is a compound that when administered to an animal in an effective manner, is capable of protecting that animal from disease caused by a parasitic helminth. As such, the parasitic helminth is essentially incapable of causing disease in an animal that is immunized with a filariid nematode CP protein of the present invention. In accordance with the present invention, the ability of a CP protein of the present invention to protect an animal from disease by a parasitic helminth refers to the ability of that protein to treat, ameliorate and/or prevent disease, including infection leading to disease, caused by the parasitic helminth, preferably by eliciting an immune response against the parasitic helminth. Such an immune response can include humoral and/or cellular immune responses.

Suitable parasites to target include any parasite that is susceptible to inhibition of cysteine protease activity. In one embodiment, such a parasite is essentially incapable of causing disease in an animal administered a CP protein of the present invention. As such, a parasite to target includes any parasite that produces a protein having one or more epitopes that can be targeted by a humoral and/or cellular immune response against a CP protein of the present invention and/or that can be targeted by a compound that otherwise inhibits CP activity, thereby resulting in the reduced ability of the parasite to cause disease in an animal. Suitable and preferred parasites to target include those parasitic helminths disclosed above as being useful in the production of filariid nematode proteins of the present invention. Additional suitable and preferred parasitic helminths to target are listed elsewhere herein.

It is to be appreciated that the present invention also includes mimetopes of CP proteins of the present invention that can be used in accordance with methods as disclosed for CP proteins of the present invention. As used herein, a mimetope of a CP protein of the present invention refers to any compound that is able to mimic the activity of such a CP protein, often because the mimetope has a structure that mimics the CP protein. Mimetopes can be, but ate not limited to: peptides that have been modified to decrease their susceptibility to degradation; anti-idiotypic and/or catalytic antibodies, or fragments thereof; non-proteinaceous immunogenic portions of an isolated protein (e.g., carbohydrate structures); and synthetic or natural organic molecules, including nucleic acids. Such mimetopes can be designed using computer-generated structures of proteins of the present invention. Mimetopes can also be obtained by generating random samples of molecules, such as oligonucleotides, peptides or other organic molecules, and screening such samples by affinity chromatography techniques using the corresponding binding partner.

One embodiment of the present invention is a fusion protein that includes a filariid nematode CP protein-containing domain attached to a fusion segment. Inclusion of a fusion segment as part of a CP protein of the present invention can enhance the protein's stability during production, storage and/or use. Depending on the segment's characteristics, a fusion segment can also act as an immunopotentiator to enhance the immune response mounted by an animal immunized with a filariid nematode CP protein containing such a fusion segment. Furthermore, a fusion segment can function as a tool to simplify purification of a filariid nematode CP protein, such as to enable purification of the resultant fusion protein using affinity chromatography. A suitable fusion segment can be a domain of any size that has the desired function (e.g., imparts increased stability, imparts increased immunogenicity to a protein, and/or simplifies purification of a protein). It is within the scope of the present invention to use one or more fusion segments. Fusion segments can be joined to amino and/or carboxyl termini of the CP-containing domain of the protein. Linkages between fusion segments and CP-containing domains of fusion proteins can be susceptible to cleavage in order to enable straight-forward recovery of the CP-containing domains of such proteins. Fusion proteins are preferably produced by culturing a recombinant cell transformed with a fusion nucleic acid molecule that encodes a protein including the fusion segment attached to either the carboxyl and/or amino terminal end of a CP-containing domain.

Preferred fusion segments for use in the present invention include a glutathione binding domain, such as Schistosoma japonicum glutathione-S-transferase (GST) or a portion thereof capable of binding to glutathione; a metal binding domain, such as a poly-histidine segment capable of binding to a divalent metal ion; an immunoglobulin binding domain, such as Protein A, Protein G, T cell, B cell, Fc receptor or complement protein antibody-binding domains; a sugar binding domain such as a maltose binding domain from a maltose binding protein; and/or a “tag” domain (e.g., at least a portion of β-galactosidase, a strep tag peptide, other domains that can be purified using compounds that bind to the domain, such as monoclonal antibodies). More preferred fusion segments include metal binding domains, such as a polyhistidine segment; a maltose binding domain; a strep tag peptide, such as that available from Biometra in Tampa, Fla.; and an S10 peptide. An example of a particularly preferred fusion protein of the present invention is PHIS-PDiCP 314 and PHIS-POvCP 401 production of which is disclosed herein.

Another embodiment of the present invention is a filariid nematode CP protein that also includes at least one additional protein segment that is capable of protecting an animal from one or more diseases. Such a multivalent protective protein can be produced by culturing a cell transformed with a nucleic acid molecule comprising two or more nucleic acid domains joined together in such a manner that the resulting nucleic acid molecule is expressed as a multivalent protective compound containing at least two protective compounds, or portions thereof, capable of protecting an animal from diseases caused, for example, by at least one infectious agent.

Examples of multivalent protective compounds include, but are not limited to, a CP protein of the present invention attached to one or more compounds protective against one or more other infectious agents, particularly an agent that infects humans, cats, dogs, cattle and/or horses, such as, but not limited to: viruses (e.g., caliciviruses, distemper viruses, hepatitis viruses, herpesviruses, immunodeficiency viruses, infectious peritonitis viruses, leukemia viruses, panleukopenia viruses, parvoviruses, rabies viruses, other cancer-causing or cancer-related viruses); bacteria (e.g., Leptospira, Rochalimaea); fungi and fungal-related microorganisms (e.g., Candida, Cryptococcus, Histoplasma); and other parasites (e.g., Babesia, Cryptosporidium, Eimeria, Encephalitozoon, Hepatozoon, Isospora, Microsporidia, Neospora, Nosema, Plasmodium, Pneumocystis, Toxoplasma, as well as helminth parasites, such as those disclosed herein). In one embodiment, a D. immitis CP protein of the present invention is attached to one or more additional compounds protective against heartworm. In another embodiment, an O. volvulus CP protein of the present invention is attached to one or more additional compounds protective against onchocerciasis.

A preferred filariid nematode CP protein of the present invention is a protein encoded by a nucleic acid molecule that hybridizes under stringent hybridization conditions with nucleic acid molecule nDiCP 1298 , nucleic acid molecule nDiCP 1304 , nucleic acid molecule nOvCP 291 , and/or nOvCP 1306 . Such a CP protein is encoded by a nucleic acid molecule that hybridizes under stringent hybridization conditions with a nucleic acid molecule having a sequence complementary to nucleic acid sequence SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:14, SEQ ID NO:16, SEQ ID NO:32, SEQ ID NO:34, and SEQ ID NO:37; i.e., nucleic acid sequences SEQ ID NO:26, SEQ ID NO:27, SEQ ID NO:28, SEQ ID NO:29, SEQ ID NO:30, SEQ ID NO:31, SEQ ID NO:35, SEQ ID NO:36, SEQ ID NO:39, and/or other sequences disclosed herein.

The nucleic acid molecule nDiCP 1298 , contains an open reading frame which is represented herein by SEQ ID NO:1. The open reading frame in nDiCP 1298 (SEQ ID NO:1) extends from the first nucleotide up to the stop codon beginning at about nucleotide 1195 and encodes a protein of about 398 amino acids, denoted herein as PDiCP 398 , the deduced amino acid sequence of which is represented herein as SEQ ID NO:2. The sequence represented by SEQ ID NO:1 suggests that an initiating methionine (ATG) may be located at about nucleotides 97 through 99. Assuming that this ATG represents the initiation (start) codon and that nucleotides 1195 through about nucleotide 1197 of SEQ ID NO:1 represent the termination (stop) codon, then SEQ ID NO:1 encodes a full-length D. immitis CP protein having an amino acid sequence of about 366 amino acids, denoted herein as PDiCP 366 . That open reading frame is denoted herein as nucleic acid molecule nDiCP 1098 which spans from about nucleotide 97 through about nucleotide 1194 of SEQ ID NO:1.

Comparison of amino acid sequence SEQ ID NO:2 with amino acid sequences reported in GenBank indicates that the significant homology started at about amino acid 85 of SEQ ID NO:2, corresponding to an ATG codon in SEQ ID NO:1 spanning from about nucleotide 253 through about nucleotide 255. While not being bound by theory, this comparison suggests that the mature D. immitis cysteine protease is a protein of about 314 amino acids, denoted herein as PDiCP 314 which has the deduced amino acid sequence represented herein as SEQ ID NO:4. PDiCP 314 is encoded by a nucleic acid molecule of about 942 nucleotides, denoted herein as nDiCP 942 t, he nucleic acid sequence of which is represented herein as SEQ ID NO:3, which corresponds to a region spanning from about nucleotide 253 through about nucleotide 1194 of SEQ ID NO:1. Based on SEQ ID NO:4, PDiCP 314 has a calculated molecular weight of about 36.2 kD and an estimated pI of 9.36.

Additional sequence analyses of D. immitis L3 cysteine protease nucleic acid molecule nDiCP 1298 indicated that the nucleic acid molecule apparently included an extra six nucleotides—this nucleic acid molecule is hence referred to as nDiCP 1304 . The nucleic acid sequence of nucleic acid molecule nDiCP 1304 is represented herein by SEQ ID NO:32 (the coding strand) and SEQ ID NO:35 (the complementary strand). SEQ ID NO:32 contains an apparent partial coding region, truncated at the 5′ end.

Translation of SEQ ID NO:32 suggests that nucleic acid molecule nDiCP 1304 encodes about 400 amino acids of a D. immitis cysteine protease protein, which is referred to herein as PDiCP 400 , assuming a first in-frame codon spanning from about nucleotide 1 through about nucleotide 3 and a stop codon spanning from about nucleotide 1201 through about nucleotide 1203 of SEQ ID NO:32. The deduced amino acid sequence of PDiCP 400 is represented as SEQ ID NO:33. Comparison of amino acid sequence SEQ ID NO:33 with amino acid sequences reported in GenBank indicates that SEQ ID NO: 33 (in its entirety)is most closely homologous, at about 38 percent identity, to Bos taurus cathepsin L.

The nucleic acid molecule nOvCP 291 contains an open reading frame which is represented herein by SEQ ID NO:5. The open reading frame in nOvCP 291 (SEQ ID NO:5) extends from about the second nucleotide up to the stop codon beginning at about nucleotide 218 and encodes a protein of about 72 amino acids, denoted herein as POvCP 72 , the deduced amino acid sequence of which is represented herein as SEQ ID NO:6. The coding region of POvCP72 is encoded by the nucleic acid molecule nOvCP 216 which is represented herein as SEQ ID NO:7.

A composite nucleic acid sequence including an O. volvulus cysteine protease apparent full-length coding region, referred to herein as nOvCP 1306 , was deduced using the nucleic acid sequence of nOvCP 291 and nOvCP 1272 , and is denoted herein as SEQ ID NO:14 (the coding strand) and SEQ ID NO:30 (the complementary strand).

Translation of SEQ ID NO:14 suggests that nucleic acid molecule nOvCP 1306 encodes about 401 amino acids of a O. volvulus cysteine protease protein, which is referred to herein as POvCP 401 , assuming an open reading frame spanning from about nucleotide 20 through about nucleotide 1222 of SEQ ID NO:14 with a first ATG codon spanning from about nucleotide 20 through about nucleotide 22 of SEQ ID NO:14 and a termination (stop) codon spanning from about nucleotide 1223 through about nucleotide 1225 of SEQ ID NO:14. The deduced amino acid sequence of POvCP 401 is represented herein as SEQ ID NO:17. Comparison of amino acid sequence SEQ ID NO:17 with amino acid sequences reported in GenBank indicates that SEQ ID NO:17 is about 44% identical over a region of about 330 amino acids to the amino acid sequence of the rabbit cathepsin K precursor. It is also to be noted that the amino acid sequence of O. volvulus cysteine protease protein POvCP 401 is about 49% identical to the coding region of D. immitis cysteine protease protein PDiCP 398 .

Another embodiment of the present invention is an isolated filariid nematode nucleic acid molecule that hybridizes under stringent hybridization conditions with a gene selected from the group consisting of a D. immitis L3 larval cysteine protease gene and an O. volvulus L3 larval cysteine protease gene. The identifying characteristics of such genes are heretofore described. A nucleic acid molecule of the present invention can include an isolated natural filariid nematode CP gene or a homologue thereof, the latter of which is described in more detail below. A nucleic acid molecule of the present invention can include one or more regulatory regions, full-length or partial coding regions, or combinations thereof. The minimal size of a nucleic acid molecule of the present invention is the minimal size that can form a stable hybrid with one of the aforementioned genes under stringent hybridization conditions. Suitable and preferred filariid nematodes are disclosed above.

In accordance with the present invention, an isolated nucleic acid molecule is a nucleic acid molecule that is not in its natural milieu (i.e., that has been subject to human manipulation). As such, “isolated” does not reflect the extent to which the nucleic acid molecule has been purified. An isolated nucleic acid molecule can include DNA, RNA, or derivatives of either DNA or RNA.

An isolated filariid nematode CP nucleic acid molecule of the present invention can be obtained from its natural source either as an entire (i.e., complete) gene or a portion thereof capable of forming a stable hybrid with that gene. An isolated filariid nematode CP nucleic acid molecule can also be produced using recombinant DNA technology (e.g., polymerase chain reaction (PCR) amplification, cloning) or chemical synthesis. Isolated filariid nematode CP nucleic acid molecules include natural nucleic acid molecules and homologues thereof, including, but not limited to, natural allelic variants and modified nucleic acid molecules in which nucleotides have been inserted, deleted, substituted, and/or inverted in such a manner that such modifications do not substantially interfere with the nucleic acid molecule's ability to encode a filariid nematode CP protein of the present invention or to form stable hybrids under stringent conditions with natural gene isolates.

A filariid nematode CP nucleic acid molecule homologue can be produced using a number of methods known to those skilled in the art (see, for example, Sambrook et al., ibid.). For example, nucleic acid molecules can be modified using a variety of techniques including, but not limited to, classic mutagenesis techniques and recombinant DNA techniques, such as site-directed mutagenesis, chemical treatment of a nucleic acid molecule to induce mutations, restriction enzyme cleavage of a nucleic acid fragment, ligation of nucleic acid fragments, polymerase chain reaction (PCR) amplification and/or mutagenesis of selected regions of a nucleic acid sequence, synthesis of oligonucleotide mixtures and ligation of mixture groups to “build” a mixture of nucleic acid molecules and combinations thereof. Nucleic acid molecule homologues can be selected from a mixture of modified nucleic acids by screening for the function of the protein encoded by the nucleic acid (e.g., ability to elicit an immune response against at least one epitope of a filariid nematode CP protein) and/or by hybridization with a D. immitis CP gene and/or with an O. volvulus CP gene.

An isolated nucleic acid molecule of the present invention can include a nucleic acid sequence that encodes at least one filariid nematode CP protein of the present invention, examples of such proteins being disclosed herein. Although the phrase “nucleic acid molecule” primarily refers to the physical nucleic acid molecule and the phrase “nucleic acid sequence” primarily refers to the sequence of nucleotides on the nucleic acid molecule, the two phrases can be used interchangeably, especially with respect to a nucleic acid molecule, or a nucleic acid sequence, being capable of encoding a filariid nematode CP protein. As heretofore disclosed, filariid nematode CP proteins of the present invention include, but are not limited to, proteins having full-length filariid nematode CP coding regions, proteins having partial filariid nematode CP coding regions, fusion proteins, multivalent protective proteins and combinations thereof.

A preferred nucleic acid molecule of the present invention, when administered to an animal, is capable of protecting that animal from disease caused by a parasitic helminth. As will be disclosed in more detail below, such a nucleic acid molecule can be, or encode, an antisense RNA, a molecule capable of triple helix formation, a ribozyme, or other nucleic acid-based drug compound. In additional embodiments, a nucleic acid molecule of the present invention can encode a protective protein, the nucleic acid molecule being delivered to the animal by direct injection (i.e, as a naked nucleic acid) or in a vehicle such as a recombinant virus vaccine or a recombinant cell vaccine.

Knowing the nucleic acid sequences of certain filariid nematode CP nucleic acid molecules of the present invention allows one skilled in the art to, for example, (a) make copies of those nucleic acid molecules, (b) obtain nucleic acid molecules including at least a portion of such nucleic acid molecules (e.g., nucleic acid molecules including full-length genes, full-length coding regions, regulatory control sequences, truncated coding regions), and (c) obtain CP nucleic acid molecules for other filariid nematodes, particularly since, as described in detail in the Examples section, knowledge of D. immitis CP nucleic acid molecules of the present invention enabled the isolation of O. volvulus CP nucleic acid molecules of the present invention. Such nucleic acid molecules can be obtained in a variety of ways including screening appropriate expression libraries with antibodies of the present invention; traditional cloning techniques using oligonucleotide probes of the present invention to screen appropriate libraries or DNA; and PCR amplification of appropriate libraries or DNA using oligonucleotide primers of the present invention. Preferred libraries to screen or from which to amplify nucleic acid molecule include parasitic helminth L3 larval libraries as well as genomic DNA libraries. Similarly, preferred DNA sources to screen or from which to amplify nucleic acid molecules include parasitic helminth L3 larval DNA and genomic DNA. Techniques to clone and amplify genes are disclosed, for example, in Sambrook et al., ibid.

The present invention also includes nucleic acid molecules that are oligonucleotides capable of hybridizing, under stringent hybridization conditions, with complementary regions of other, preferably longer, nucleic acid molecules of the present invention such as those comprising filariid nematode CP genes or other filariid nematode CP nucleic acid molecules. oligonucleotides of the present invention can be RNA, DNA, or derivatives of either. The minimal size of such oligonucleotides is the size required to form a stable hybrid between a given oligonucleotide and the complementary sequence on another nucleic acid molecule of the present invention. Minimal size characteristics are disclosed herein. The size of the oligonucleotide must also be sufficient for the use of the oligonucleotide in accordance with the present invention. Oligonucleotides of the present invention can be used in a variety of applications including, but not limited to, as probes to identify additional nucleic acid molecules, as primers to amplify or extend nucleic acid molecules or in therapeutic applications to inhibit CP protein production or activity. Such therapeutic applications include the use of such oligonucleotides in, for example, antisense-, triplex formation-, ribozyme- and/or RNA drug-based technologies. The present invention, therefore, includes such oligonucleotides and methods to protect animals from disease caused by parasitic helminths by use of one or more of such technologies. Appropriate oligonucleotide-containing therapeutic compositions can be administered to an animal, using techniques known to those skilled in the art, either prior to or after infection by a parasitic helminth such as D. immitis or O. volvulus in order to protect the animal from disease.

The present invention also includes a recombinant vector, which includes at least one filariid nematode CP nucleic acid molecule of the present invention, inserted into any vector capable of delivering the nucleic acid molecule into a host cell. Such a vector contains heterologous nucleic acid sequences, that is nucleic acid sequences that are not naturally found adjacent to nucleic acid molecules of the present invention and that preferably are derived from a species other than the species from which the nucleic acid molecule(s) are derived. The vector can be either RNA or DNA, either prokaryotic or eukaryotic, and typically is a virus or a plasmid. Recombinant vectors can be used in the cloning, sequencing, and/or otherwise manipulating of filariid nematode CP nucleic acid molecules of the present invention. One type of recombinant vector, referred to herein as a recombinant molecule and described in more detail below, can be used in the expression of nucleic acid molecules of the present invention. Preferred recombinant vectors are capable of replicating in the transformed cell.

Isolated filariid nematode CP proteins of the present invention can be produced in a variety of ways, including production and recovery of natural proteins, production and recovery of recombinant proteins, and chemical synthesis of the proteins. In one embodiment, an isolated protein of the present invention is produced by culturing a cell capable of expressing the protein under conditions effective to produce the protein, and recovering the protein. A preferred cell to culture is a recombinant cell that is capable of expressing the protein, the recombinant cell being produced by transforming a host cell with one or more nucleic acid molecules of the present invention. Transformation of a nucleic acid molecule into a cell can be accomplished by any method by which a nucleic acid molecule can be inserted into the cell. Transformation techniques include, but are not limited to, transfection, electroporation, microinjection, lipofection, adsorption, and protoplast fusion. A recombinant cell may remain unicellular or may grow into a tissue, organ or a multicellular organism. Transformed nucleic acid molecules of the present invention can remain extrachromosomal or can integrate into one or more sites within a chromosome of the transformed (i.e., recombinant) cell in such a manner that their ability to be expressed is retained. Suitable and preferred nucleic acid molecules with which to transform a cell are as disclosed herein for suitable and preferred filariid nematode CP nucleic acid molecules per se.

A recombinant cell is preferably produced by transforming a host cell with one or more recombinant molecules, each comprising one or more nucleic acid molecules of the present invention operatively linked to an expression vector containing one or more transcription control sequences. The phrase operatively linked refers to insertion of a nucleic acid molecule into an expression vector in a manner such that the molecule is able to be expressed when transformed into a host cell. As used herein, an expression vector is a DNA or RNA vector that is capable of transforming a host cell and of effecting expression of a specified nucleic acid molecule. Preferably, the expression vector is also capable of replicating within the host cell. Expression vectors can be either prokaryotic or eukaryotic, and are typically viruses or plasmids. Expression vectors of the present invention include any vectors that function (i.e., direct gene expression) in recombinant cells of the present invention, including in bacterial, fungal, parasite, insect, other animal, and plant cells. Preferred expression vectors of the present invention can direct gene expression in bacterial, yeast, helminth or other parasite, insect and mammalian cells and more preferably in the cell types heretofore disclosed.

Recombinant molecules of the present invention may also (a) contain secretory signals (i.e., signal segment nucleic acid sequences) to enable an expressed filariid nematode CP protein of the present invention to be secreted from the cell that produces the protein and/or (b) contain fusion sequences which lead to the expression of nucleic acid molecules of the present invention as fusion proteins. Examples of suitable signal segments and fusion segments encoded by fusion segment nucleic acids are disclosed herein. Eukaryotic recombinant molecules may include intervening and/or untranslated sequences surrounding and/or within the nucleic acid sequences of nucleic acid molecules of the present invention.

Nucleic acid molecules of the present invention can be operatively linked to expression vectors containing regulatory sequences such as transcription control sequences, translation control sequences, origins of replication, and other regulatory sequences that are compatible with the recombinant cell and that control the expression of nucleic acid molecules of the present invention. In particular, recombinant molecules of the present invention include transcription control sequences. Transcription control sequences are sequences which control the initiation, elongation, and termination of transcription. Particularly important transcription control sequences are those which control transcription initiation, such as promoter, enhancer, operator and repressor sequences. Suitable transcription control sequences include any transcription control sequence that can function in at least one of the recombinant cells of the present invention. A variety of such transcription control sequences are known to those skilled in the art. Preferred transcription control sequences include those which function in bacterial, yeast, helminth or other parasite, insect and mammalian cells, such as, but not limited to, tac, lac, trp, trc, oxy-pro, omp/lpp, rrnB, bacteriophage lambda (such as lambda P L and lambda P R and fusions that include such promoters), bacteriophage T7, T7lac, bacteriophage T3, bacteriophage SP6, bacteriophage SP01, metallothionein, alpha-mating factor, Pichia alcohol oxidase, alphavirus subgenomic promoters (such as Sindbis virus subgenomic promoters), antibiotic resistance gene, baculovirus, Heliothis zea insect virus, vaccinia virus, herpesvirus, poxvirus, adenovirus, cytomegalovirus (such as intermediate early promoters, simian virus 40, retrovirus, actin, retroviral long terminal repeat, Rous sarcoma virus, heat shock, phosphate and nitrate transcription control sequences as well as other sequences capable of controlling gene expression in prokaryotic or eukaryotic cells.

Transcription control sequences of the present invention can also include naturally occurring transcription control sequences naturally associated with a filariid nematode nucleic acid molecule, such as a D. immitis or O. volvulus molecule prior to isolation.

A recombinant molecule of the present invention is a molecule that can include at least one of any nucleic acid molecule heretofore described operatively linked to at least one of any transcription control sequence capable of effectively regulating expression of the nucleic acid molecule(s) in the cell to be transformed, examples of which are disclosed herein.

Coli :pHis-nOvCP 1203 . Details regarding the production of these recombinant cells are disclosed herein.

Recombinant cells of the present invention can also be co-transformed with one or more recombinant molecules including filariid nematode CP nucleic acid molecules encoding one or more proteins of the present invention and one or more other proteins useful in the production of multivalent vaccines which can include one or more protective compounds.

It may be appreciated by one skilled in the art that use of recombinant DNA technologies can improve expression of transformed nucleic acid molecules by manipulating, for example, the number of copies of the nucleic acid molecules within a host cell, the efficiency with which those nucleic acid molecules are transcribed, the efficiency with which the resultant transcripts are translated, and the efficiency of post-translational modifications. Recombinant techniques useful for increasing the expression of nucleic acid molecules of the present invention include, but are not limited to, operatively linking nucleic acid molecules to high-copy number plasmids, integration of the nucleic acid molecules into one or more host cell chromosomes, addition of vector stability sequences to plasmids, substitutions or modifications of transcription control signals (e.g., promoters, operators, enhancers), substitutions or modifications of translational control signals (e.g., ribosome binding sites, Shine-Dalgarno sequences), modification of nucleic acid molecules of the present invention to correspond to the codon usage of the host cell, deletion of sequences that destabilize transcripts, and use of control signals that temporally separate recombinant cell growth from recombinant enzyme production during fermentation. The activity of an expressed recombinant protein of the present invention may be improved by fragmenting, modifying, or derivatizing nucleic acid molecules encoding such a protein.

In accordance with the present invention, recombinant cells of the present invention can be used to produce one or more proteins of the present invention by culturing such cells under conditions effective to produce such a protein, and recovering the protein. Effective conditions to produce a protein include, but are not limited to, appropriate media, bioreactor, temperature, pH and oxygen conditions that permit protein production. An appropriate, or effective, medium refers to any medium in which a cell of the present invention, when cultured, is capable of producing a filariid nematode CP protein of the present invention. Such a medium is typically an aqueous medium comprising assimilable carbon, nitrogen and phosphate sources, as well as appropriate salts, minerals, metals and other nutrients, such as vitamins. The medium may comprise complex nutrients or may be a defined minimal medium. Cells of the present invention can be cultured in conventional fermentation bioreactors, which include, but are not limited to, batch, fed-batch, cell recycle, and continuous fermentors. Culturing can also be conducted in shake flasks, test tubes, microtiter dishes, and petri plates. Culturing is carried out at a temperature, pH and oxygen content appropriate for the recombinant cell. Such culturing conditions are well within the expertise of one of ordinary skill in the art. Examples of suitable conditions are included in the Examples section.

Depending on the vector and host system used for production, resultant proteins of the present invention may either remain within the recombinant cell; be secreted into the fermentation medium; be secreted into a space between two cellular membranes, such as the periplasmic space in E. coli ; or be retained on the outer surface of a cell or viral membrane.

The phrase “recovering the protein” refers simply to collecting the whole fermentation medium containing the protein and need not imply additional steps of separation or purification. Proteins of the present invention can be purified using a variety of standard protein purification techniques, such as, but not limited to, affinity chromatography, ion exchange chromatography, filtration, electrophoresis, hydrophobic interaction chromatography, gel filtration chromatography, reverse phase chromatography, concanavalin A chromatography, chromatofocusing and differential solubilization. Proteins of the present invention are preferably retrieved in “substantially pure” form. As used herein, “substantially pure” refers to a purity that allows for the effective use of the protein as a therapeutic composition or diagnostic. A therapeutic composition for animals, for example, should exhibit no substantial toxicity and should be capable of stimulating the production of antibodies in a treated animal.

The present invention also includes isolated antibodies capable of selectively binding to a filariid nematode CP protein of the present invention or to a mimetope thereof. Such antibodies are also referred to herein as anti-filariid nematode CP antibodies. Particularly preferred antibodies of this embodiment include anti- D. immitis CP antibodies and anti- O. volvulus CP antibodies.

Isolated antibodies are antibodies that have been removed from their natural milieu. The term “isolated” does not refer to the state of purity of such antibodies. As such, isolated antibodies can include anti-sera containing such antibodies, or antibodies that have been purified to varying degrees.

As used herein, the term “selectively binds to” refers to the ability of antibodies of the present invention to preferentially bind to specified proteins and mimetopes thereof of the present invention. Binding can be measured using a variety of methods known to those skilled in the art including immunoblot assays, immunoprecipitation assays, radioimmunoassays, enzyme immunoassays (e.g., ELISA), immunofluorescent antibody assays and immunoelectron microscopy; see, for example, Sambrook et al., ibid. An anti-filariid nematode CP antibody preferably binds to a filariid nematode CP protein in such a way as to reduce the activity of that protein.

Antibodies of the present invention can be either polyclonal or monoclonal antibodies. Antibodies of the present invention include functional equivalents such as antibody fragments and genetically-engineered antibodies, including single chain antibodies, that are capable of selectively binding to at least one of the epitopes of the protein or mimetope used to obtain the antibodies. Antibodies of the present invention also include chimeric antibodies that can bind to more than one epitope. Preferred antibodies are raised in response to proteins, or mimetopes thereof, that are encoded, at least in part, by a nucleic acid molecule of the present invention.

A preferred method to produce antibodies of the present invention includes (a) administering to an animal an effective amount of a protein or mimetope thereof of the present invention to produce the antibodies and (b) recovering the antibodies. In another method, antibodies of the present invention are produced recombinantly using techniques as heretofore disclosed to produce filariid nematode CP proteins of the present invention. Antibodies raised against defined proteins or mimetopes can be advantageous because such antibodies are not substantially contaminated with antibodies against other substances that might otherwise cause interference in a diagnostic assay or side effects if used in a therapeutic composition.

Antibodies of the present invention have a variety of potential uses that are within the scope of the present invention. For example, such antibodies can be used (a) as therapeutic compounds to passively immunize an animal in order to protect the animal from parasitic helminths susceptible to treatment by such antibodies, (b) as reagents in assays to detect infection by such filariid nematodes and/or (c) as tools to screen expression libraries and/or to recover desired proteins of the present invention from a mixture of proteins and other contaminants. Furthermore, antibodies of the present invention can be used to target cytotoxic agents to parasitic helminths of the present invention in order to directly kill such helminths. Targeting can be accomplished by conjugating (i.e., stably joining) such antibodies to the cytotoxic agents using techniques known to those skilled in the art. Suitable cytotoxic agents are known to those skilled in the art.

One embodiment of the present invention is a therapeutic composition that, when administered to an animal in an effective manner, is capable of protecting that animal from disease caused by a parasitic helminth. Therapeutic compositions of the present invention include at least one of the following protective compounds: (a) an isolated filariid nematode L3 larval cysteine protease protein or a mimetope thereof; (b) an isolated filariid nematode nucleic acid molecule that hybridizes under stringent hybridization conditions with a D. immitis L3 larval cysteine protease gene and/or an O. volvulus L3 larval cysteine protease gene; (c) an isolated antibody that selectively binds to a filariid nematode L3 larval cysteine protease protein; (d) an inhibitor of cysteine protease activity identified by its ability to inhibit filariid nematode L3 larval cysteine protease activity; and (e) a mixture (i.e., combination) of at least two of the compounds.

Therapeutic compositions of the present invention can be administered to any animal susceptible to such therapy, preferably to mammals, and more preferably to dogs, cats, humans, ferrets, horses, cattle, sheep and other pets, economic food animals and/or zoo animals. Preferred animals to protect against heartworm include dogs, cats, humans and ferrets, with dogs and cats being particularly preferred. Preferred animals to protect against onchocerciasis include humans, cattle and horses, with humans being particularly preferred.

In one embodiment, a therapeutic composition of the present invention can be administered to the vector in which the parasitic helminth develops, such as to a mosquito in order to prevent the spread of heartworm or to a black fly in order to prevent the spread of onchocerciasis. Such administration could be orally or by developing transgenic vectors capable of producing at least one therapeutic composition of the present invention. In another embodiment, a vector, such as a mosquito or a black fly, can ingest therapeutic compositions present in the blood of a host that has been administered a therapeutic composition of the present invention.

Therapeutic compositions of the present invention can be formulated in an excipient that the animal to be treated can tolerate. Examples of such excipients include water, saline, Ringer's solution, dextrose solution, Hank's solution, and other aqueous physiologically balanced salt solutions. Nonaqueous vehicles, such as fixed oils, sesame oil, ethyl oleate, or triglycerides may also be used. Other useful formulations include suspensions containing viscosity enhancing agents, such as sodium carboxymethylcellulose, sorbitol, or dextran. Excipients can also contain minor amounts of additives, such as substances that enhance isotonicity and chemical stability. Examples of buffers include phosphate buffer, bicarbonate buffer and Tris buffer, while examples of preservatives include thimerosal, m- or o-cresol, formalin and benzyl alcohol. Standard formulations can either be liquid injectables or solids which can be taken up in a suitable liquid as a suspension or solution for injection. Thus, in a non-liquid formulation, the excipient can comprise dextrose, human serum albumin, preservatives, etc., to which sterile water or saline can be added prior to administration.

In one embodiment of the present invention, the therapeutic composition can also include an immunopotentiator, such as an adjuvant or a carrier. Adjuvants are typically substances that generally enhance the immune response of an animal to a specific antigen. Suitable adjuvants include, but are not limited to, Freund's adjuvant; other bacterial cell wall components; aluminum-based salts; calcium-based salts; silica; polynucleotides; toxoids; serum proteins; viral coat proteins; other bacterial-derived preparations; gamma interferon; block copolymer adjuvants, such as Hunter's Titermax™ adjuvant (Vaxcel™, Inc. Norcross, Ga.); Ribi adjuvants (available from Ribi ImmunoChem Research, Inc., Hamilton, Mont.); and saponins and their derivatives, such as Quil A (available from Superfos Biosector A/S, Denmark). Carriers are typically compounds that increase the half-life of a therapeutic composition in the treated animal. Suitable carriers include, but are not limited to, polymeric controlled release formulations, biodegradable implants, liposomes, bacteria, viruses, oils, esters, and glycols.

One embodiment of the present invention is a controlled release formulation that is capable of slowly releasing a composition of the present invention into an animal. As used herein, a controlled release formulation comprises a composition of the present invention in a controlled release vehicle. Suitable controlled release vehicles include, but are not limited to, biocompatible polymers, other polymeric matrices, capsules, microcapsules, microparticles, bolus preparations, osmotic pumps, diffusion devices, liposomes, lipospheres, and transdermal delivery systems. Other controlled release formulations of the present invention include liquids that, upon administration to an animal, form a solid or a gel in situ. Preferred controlled release formulations are biodegradable (i.e., bioredible).

A preferred controlled release formulation of the present invention is capable of releasing a composition of the present invention into the blood of the treated animal at a constant rate sufficient to attain therapeutic dose levels of the composition to protect an animal from disease caused by parasitic helminths. The therapeutic composition is preferably released over a period of time ranging from about 1 to about 12 months. A controlled release formulation of the present invention is capable of effecting a treatment for preferably at least about 1 month, more preferably at least about 3 months and even more preferably for at least about 6 months, even more preferably for at least about 9 months, and even more preferably for at least about 12 months.

In order to protect an animal from disease caused by a parasitic helminth of the present invention, a therapeutic composition of the present invention is administered to the animal in an effective manner such that the composition is capable of protecting that animal from a disease caused by a parasitic helminth. For example, an isolated protein or mimetope thereof, when administered to an animal in an effective manner, is able to elicit (i.e., stimulate) an immune response, preferably including both a humoral and cellular response, that is sufficient to protect the animal from the disease. Similarly, an antibody of the present invention, when administered to an animal in an effective manner, is administered in an amount so as to be present in the animal at a titer that is sufficient to protect the animal from the disease, at least temporarily. Oligonucleotide nucleic acid molecules of the present invention can also be administered in an effective manner, thereby reducing expression of filariid nematode CP proteins in order to interfere with development of parasitic helminths targeted in accordance with the present invention.

Therapeutic compositions of the present invention can be administered to animals prior to infection in order to prevent infection and/or can be administered to animals after infection in order to treat disease caused by the parasitic helminth. For example, proteins, mimetopes thereof, and antibodies thereof can be used as immunotherapeutic agents.

Acceptable protocols to administer therapeutic compositions in an effective manner include individual dose size, number of doses, frequency of dose administration, and mode of administration. Determination of such protocols can be accomplished by those skilled in the art. A suitable single dose is a dose that is capable of protecting an animal from disease when administered one or more times over a suitable time period. For example, a preferred single dose of a protein, mimetope or antibody therapeutic composition is from about 1 microgram (μg) to about 10 milligrams (mg) of the therapeutic composition per kilogram body weight of the animal. Booster vaccinations can be administered from about 2 weeks to several years after the original administration. Booster vaccinations preferably are administered when the immune response of the animal becomes insufficient to protect the animal from disease. A preferred administration schedule is one in which from about 10 μg to about 1 mg of the therapeutic composition per kg body weight of the animal is administered from about one to about two times over a time period of from about 2 weeks to about 12 months. Modes of administration can include, but are not limited to, subcutaneous, intradermal, intravenous, intranasal, oral, transdermal and intramuscular routes.

According to one embodiment, a nucleic acid molecule of the present invention can be administered to an animal in a fashion to enable expression of that nucleic acid molecule into a protective protein or protective RNA (e.g., antisense RNA, ribozyme or RNA drug) in the animal to be protected from disease. Nucleic acid molecules can be delivered to an animal in a variety of methods including, but hot limited to, (a) administering a naked (i.e., not packaged in a viral coat or cellular membrane) nucleic acid vaccine (e.g., as naked DNA or RNA molecules, such as is taught, for example in Wolff et al., 1990 , Science 247, 1465-1468) or (b) administering a nucleic acid molecule packaged as a recombinant virus vaccine or as a recombinant cell vaccine (i.e., the nucleic acid molecule is delivered by a viral or cellular vehicle).

A naked nucleic acid vaccine of the present invention includes a nucleic acid molecule of the present invention and preferably includes a recombinant molecule of the present invention that preferably is replication, or otherwise amplification, competent. Such a vaccine can comprise any nucleic acid molecule or recombinant molecule of the present invention. Preferred naked nucleic acid vaccines include at least a portion of a viral genome (i.e., a viral vector). Preferred viral vectors include those based on alphaviruses, poxviruses, adenoviruses, herpesviruses, and retroviruses, with those based on alphaviruses (such as Sindbis or Semliki virus), species-specific herpesviruses and species-specific poxviruses being particularly preferred. Any suitable transcription control sequence can be used, including those disclosed as suitable for protein production. Particularly preferred transcription control sequence include cytomegalovirus intermediate early (preferably in conjunction with Intron-A), Rous Sarcoma Virus long terminal repeat, and tissue-specific transcription control sequences, as well as transcription control sequences endogenous to viral vectors if viral vectors are used. The incorporation of “strong” poly(A) sequences are also preferred.

Naked nucleic acid vaccines of the present invention can be administered in a variety of ways, with intramuscular, subcutaneous, intradermal, transdermal, intranasal and oral routes of administration being preferred. A preferred single dose of a naked nucleic acid vaccine ranges from about 1 nanogram (ng) to about 100 pg, depending on the route of administration and/or method of delivery, as can be determined by those skilled in the art. Suitable delivery methods include, for example, by injection, as drops, aerosolized and/or topically. Suitable excipients include, for example, physiologically acceptable aqueous solutions (e.g., phosphate buffered saline as well as others disclosed above), liposomes (including neutral or cationic liposomes), and other lipid membrane-based vehicles (e.g., micelles or cellular membranes).

A recombinant virus vaccine of the present invention includes a recombinant molecule of the present invention that is packaged in a viral coat and that can be expressed in an animal after administration. Preferably, the recombinant molecule is packaging-deficient. A number of recombinant viruses can be used, including, but not limited to, those based on alphaviruses, poxviruses, adenoviruses, herpesviruses, and retroviruses. Preferred recombinant virus vaccines are those based on alphaviruses (such as Sindbis virus), species-specific herpesviruses and species-specific poxviruses. Methods to produce and use recombinant virus vaccines are disclosed in PCT Publication No. WO 94/17813, by Xiong et al., published Aug. 18, 1994, which is incorporated by reference herein in its entirety.

When administered to an animal, a recombinant virus vaccine of the present invention infects cells within the. immunized animal and directs the production of a protective protein or RNA nucleic acid molecule that is capable of protecting the animal from disease caused by a parasitic helminths as disclosed herein. For example, a recombinant virus vaccine comprising a D. immitis CP nucleic acid molecule of the present invention is administered according to a protocol that results in the animal producing a sufficient immune response to protect itself from heartworm. A preferred single dose of a recombinant virus vaccine of the present invention is from about 1×10 4 to about 1×10 7 virus plaque forming units (pfu) per kilogram body weight of the animal. Administration protocols are similar to those described herein for protein-based vaccines, with subcutaneous, intramuscular, intranasal and oral administration routes being preferred.

A recombinant cell vaccine of the present invention includes recombinant cells of the present invention that express at least one protein of the present invention. Preferred recombinant cells for this embodiment include Salmonella, E. coli , Listeria, Mycobacterium, S. frugiperda , BHK, CV-1, myoblast G8, COS (e.g., COS-7), Vero, MDCK and CRFK recombinant cells. Recombinant cell vaccines of the present invention can be administered in a variety of ways but have the advantage that they can be administered orally, preferably at doses ranging from about 10 8 to about 10 12 cells per kilogram body weight. Administration protocols are similar to those described herein for protein-based vaccines. Recombinant cell vaccines can comprise whole cells or cell lysates.

The efficacy of a therapeutic composition of the present invention to protect an animal from disease caused by a parasitic helminth can be tested in a variety of ways including, but not limited to, detection of protective antibodies (using, for example, proteins or mimetopes of the present invention), detection of cellular immunity within the treated animal, or challenge of the treated animal with the parasitic helminth to determine whether the treated animal is resistant to disease. Such techniques are known to those skilled in the art.

One preferred embodiment of the present invention is the use of filariid nematode CP proteins, nucleic acid molecules and antibodies of the present invention, and particularly D. immitis CP proteins, nucleic acid molecules and antibodies of the present invention, to protect an animal from heartworm. Preferred therapeutic compositions are those that are able to inhibit at least one step in the portion of the parasite's development cycle that includes L3 larvae, third molt, L4 larvae, fourth molt and immature adult prior to entering the circulatory system. In dogs, this portion of the development cycle is about 70 days. Particularly preferred therapeutic compositions include D. immitis -based therapeutic compositions of the present invention. Such compositions are administered to animals in a manner effective to protect the animals from heartworm. Additional protection may be obtained by administering additional protective compounds, including other D. immitis proteins, nucleic acid molecules and antibodies.

Another preferred embodiment of the present invention is the use of filariid nematode CP proteins, nucleic acid molecules and antibodies of the present invention, and particularly O. volvulus CP proteins, nucleic acid molecules and antibodies of the present invention, to protect a human from onchocerciasis. Preferred therapeutic compositions are those that are able to inhibit at least one step in the portion of the parasite's development cycle that includes L3 larvae, third molt, L4 larvae, fourth molt and immature adult prior to entering the subcutaneous tissues. In humans infected with O. volvulus , this portion of the development cycle is about 150 days. Particularly preferred therapeutic compositions include O. volvulus -based therapeutic compositions of the present invention. Such compositions are administered to humans in a manner effective to protect the treated humans from onchocerciasis. Additional protection may be obtained by administering additional protective compounds, including other Onchocerca, preferably O. volvulus , proteins, nucleic acid molecules and antibodies.

An inhibitor of cysteine protease activity can be identified using parasitic helminth, and preferably D. immitis and/or O. volvulus CP proteins of the present invention. One embodiment of the present invention is a method to identify a compound capable of inhibiting cysteine protease activity of a parasitic helminth. Such a method includes the steps of (a) contacting (e.g., combining, mixing) an isolated filariid nematode CP protein with a putative inhibitory compound under conditions in which, in the absence of the compound, the protein has cysteine protease activity, and (b) determining if the putative inhibitory compound inhibits the cysteine protease activity. Putative inhibitory compounds to screen include organic molecules, antibodies (including mimetopes thereof) and substrate analogs. Methods to determine cysteine protease activity are known to those skilled in the art.

It is also within the scope of the present invention to use isolated proteins, mimetopes, nucleic acid molecules and antibodies of the present invention as diagnostic reagents to detect infection by parasitic helminths. Such diagnostic reagents can be supplemented with additional compounds that can detect other phases of the parasite's life cycle.

The following examples are provided for the purposes of illustration and are not intended to limit the scope of the present invention.

EXAMPLES

Example 1

This Example describes the cloning and sequencing of a filariid nematode cysteine protease nucleic acid molecule of the present invention.

A D. immitis cysteine protease nucleic acid molecule of about 1298 nucleotides, denoted nDiCP 1298 , was identified by its ability to encode a protein that selectively bound to at least one component of immune serum collected from a dog immunized with chemically abbreviated D. immitis larval infections in the following manner. A D. immitis cDNA expression library was constructed in Uni-ZAP™ XR vector (available from Stratagene Cloning Systems, La Jolla, Calif.), using Stratagene's ZAP-cDNA Synthesis Kit protocol and third stage larval mRNAs. Using the protocol described in the Stratagene picoBlue immunoscreening kit, the L3 larval cDNA expression library was screened with immune dog sera. The production and use of immune dog serum to identify heartworm vaccine candidates is disclosed in PCT Publication No. WO 92/13560, published Aug. 20, 1992.

Immunoscreening of duplicate plaque lifts of the cDNA library with the same immune dog serum identified the nucleic acid molecule nDiCP 1298 . The plaque-purified clone including nDiCP 1298 was converted into a double-stranded plasmid using ExAssist™ helper phage and SOLR™ E. Coli according to the in vivo excision protocol described in the Stratagene ZAP-cDNA Synthesis Kit. Double-stranded plasmid DNA was prepared using an alkaline lysis protocol, such as that described in Sambrook et al., ibid. The double-stranded plasmid containing the fragment is denoted herein as recombinant molecule pβgal-nDiCP 1298 . The plasmid DNA was digested with EcoRI and XhoI restriction endonucleases. The digestion released two D. immitis DNA fragments of about 450 and about 848 nucleotides from the nDicP 1298 nucleic acid molecule. As described in more detail below, nucleic acid molecule nDiCP 1298 has been shown to encode a cysteine protease protein.

Pursuant to 37 CFR § 1.802 (a-c), SOLR™ E. coli comprising recombinant molecule pβgal-nDiCP 1298 , designated herein as E. coli :pβgal-nDiCP 1298 , was deposited with the American Type Culture Collection (ATCC, 12301 Parklawn Drive, Rockville, Md., 20852) under the Budapest Treaty as ATCC Accession No. ATCC 98471 on Jun. 18, 1997. Pursuant to 37 CFR § 1.806, the deposit is made for a term of at least thirty (30) years and at least five (5) years after the most recent request for the furnishing of a sample of the deposit was received by the depository. Pursuant to 37 CFR § 1808 (a) (2), all restrictions imposed by the depositor on the availability to the public will be irrevocably removed upon the granting of the patent.

Nucleic acid molecule nDiCP 1298 was sequenced using the Sanger dideoxy chain termination method, as described in Sambrook et al., ibid. An about 1298 nucleotide consensus sequence of the entire nDiCP 1298 nucleic acid molecule was determined and is denoted herein as SEQ ID NO:1. The nucleic acid sequence SEQ ID NO:1 includes an open reading frame spanning from about nucleotide 1 through about nucleotide 1194, with a first ATG codon spanning from about nucleotide 97 through about nucleotide 99 and a termination (stop) codon spanning from about nucleotide 1195 through about 1197. A putative polyadenylation signal (5′ AATAAA 3′) is located from about nucleotide 1265 through about nucleotide 1270. The amino terminus of the nucleic acid sequence represented by SEQ ID NO:1 encodes a hydrophobic region as determined using a standard hydrophilicity plot.

The open reading frame extending from the first nucleotide of nDiCP 1298 up to the stop codon is a nucleic acid molecule of about 1194 nucleotides, denoted herein as nDiCP 1194 , which encodes a protein of about 398 amino acids, denoted herein as PDiCP 398 , the deduced amino acid sequence of which is represented herein as SEQ ID NO:2. Assuming that the ATG located from about nucleotide 97 through about nucleotide 99 represents the initiation (start) codon, SEQ ID NO:1 encodes a protein having an amino acid sequence of about 366 amino acids, denoted herein as PDiCP 366 . That open reading frame is denoted herein as nucleic acid molecule nDiCP 1098 and spans from about nucleotide 97 through about nucleotide 1194 of SEQ ID NO:1. Assuming that the ATG located from about nucleotide 127 through about nucleotide 129 represents the initiation codon, SEQ ID NO:1 encodes a protein having an amino acid sequence of about 356 amino acids, denoted herein as PDiCP 356 . That open reading frame is denoted herein as nucleic acid molecule nDiCP 1068 and spans from about nucleotide 127 through about nucleotide 1194 of SEQ ID NO:1. Assuming that the ATG located from about nucleotide 253 through about nucleotide 255 represents the initiation codon, SEQ ID NO:1 encodes a protein having an amino acid sequence of about 314 amino acids, denoted herein as PDiCP 314 . That open reading frame is denoted herein as nucleic acid molecule nDiCP 942 and spans from about nucleotide 253 through about nucleotide 1194 of SEQ ID NO:1.

The very highly conserved catalytic residues of members of the papain family of cysteine peptidases are a cysteine at amino acid position 25 (C25) and a histidine residue at position 159 (H159) of the mature, processed peptide. Other amino acid residues important for catalysis include a glutamine at position 19 (Q19) and asparagine at position 175 (N175). The numbering of these amino acids correspond to the amino acid position of the mature papain sequence (Genbank Acc. No. M15203).

Based on a homology alignment of the PDiCP 356 deduced amino acid sequence with known papain amino acid sequences, the predicted mature protein resulting from the processing of the PDiCP 356 sequence, referred to as PDiCP 213 (SEQ ID NO:22), would begin with the leucine at residue 144 of PDiCP 356 . PDiCP 213 also contains the papain family conserved residues believed to be involved in catalysis, namely, a cysteine at residue 25 (C25), a histidine at residue 160 which corresponds to the H159 of papain, a glutamine at position 19 (Q19) and an asparagine at residue 181 which corresponds to the N175 of papain. In addition, many members of the papain C1 family contain a proline residue at position 2 of the mature, processed enzyme. The PDiCP 213 amino acid sequence has a proline at position 2 of the predicted mature enzyme.

To confirm the D. immitis origin of the isolated L3 cysteine protease cDNA nucleic acid molecules, a Southern blot containing about 10 micrograms of EcoRI restricted D. immitis genomic DNA and Aedes aegypti genomic DNA was hybridized under stringent conditions with pβgal-nDiCP 1298 DNA radiolabeled by random priming with the Megaprime DNA Labeling System (available from Amersham Life Science, Arlington Heights, Ill.). The probe detected two bands of about 2500 and 700 nucleotides only in the D. immitis genomic DNA.

A homology search of the non-redundant protein sequence database was performed through the National Center for Biotechnology Information using the BLAST network. This database includes+SwissProt+PIR+SPUpdate+GenPept+GPUpdate. SEQ ID NO:2 was found to have significant homology to certain cysteine proteases starting at about amino acid 85 of SEQ ID NO:2, corresponding to an ATG codon in SEQ ID NO:1 spanning from about nucleotide 253 through about nucleotide 255. While not being bound by theory, this comparison suggests that the mature D. immitis cysteine protease is a protein of about 314 amino acids, denoted herein as PDiCP 314 , which has the deduced amino acid sequence represented herein as SEQ ID NO:4. PDiCP 314 is encoded by a nucleic acid molecule of about 942 nucleotides, denoted herein as nDiCP 942 , the nucleic acid sequence of which is represented herein as SEQ ID NO:3, which corresponds to a region spanning from about nucleotide 253 through about nucleotide 1194 of SEQ ID NO:1. Based on SEQ ID NO:4, PDiCP 314 has a calculated molecular weight of about 36.2 kD and an estimated pI of about 9.36.

SEQ ID NO:4 was found to be about 37% identical to Norway lobster cathepsin L (Genbank Acc. No. S47433); about 30% identical to Dictyostelium discoideum cysteine proteinase 2 (Acc. No. X03344); about 39% identical to Sarcophoga peregrina pro-cathepsin (Acc. No. LD16533); about 36% identical to Fasciola hepatica cathepsin L-like proteinases (Acc. No. S43991); about 35% identical to Fasciola hepatica cathepsin (Acc. No. L33772); about 36% identical to Schistosoma mansoni cathepsin L (Acc. No. S44151): about 36% identical to Fasciola hepatica cathepsin L-like protease (Acc. No. Z22765); about 30% identical to Trichomonas vaginalis putative cysteine proteinase (Acc. No. X77221); about 35% identical to Entamoeba histolytica cysteine proteinase (Acc. No. A23705); and about 28% identical to Trichomonas vaginalis cysteine proteinase (Acc. No. S41427).

The corresponding region of SEQ ID NO:4 is also about 23% identical to the deduced amino acid sequence of the D. immitis amplified genomic PCR fragment nDiCP 143 disclosed in PCT Patent Publication No. WO 95/32988, published Dec. 7, 1995, which is incorporated by reference herein in its entirety.

The nucleic acid sequence represented by SEQ ID NO:1 was found to be about 48.4% identical to C. papaya mRNA for chymopapain (Genbank Acc. No. X97789); about 44.7% identical to Fasciola hepatica cathepsin L-like proteinase (Genbank Acc. No. L33771); and about 42.2% identical to Schistosoma mansoni mRNA for cathepsin L (Genbank Acc. No. Z32529).

Example 2

This example discloses the production of a recombinant cell of the present invention.

Recombinant molecule pHis-nDiCP 945 , containing D. immitis L3 cysteine protease nucleic acid molecule nDiCP 945 operatively linked to trc transcription control sequences and to a fusion sequence encoding a poly-histidine segment comprising 6 histidines, was produced in the following manner. An about 945 nucleotide DNA fragment containing nucleotides spanning from about nucleotide 253 through about nucleotide 1197 of SEQ ID NO:1, called nDiCP 945 , was polymerase chain reaction (PCR) amplified from recombinant molecule pβgal-nDiCP 1298 , described in Example 1, using the following primers: primers CP sen 5′ AACGGTGAGGATCCAGCGATGAAAAAATTAGAAAC 3′ (SEQ ID NO:8) (BamHI site in bold) and CP ant 5′ ATTAAAAGATCTTTATATGGGGAATGAAGCCATCG 3′ (SEQ ID NO:9) (BglII site in bold). The PCR product was digested with BamHI and BglII restriction endonucleases, gel purified and subcloned into expression vector pTrcHisB (available from InVitrogen, San Diego, Calif.) that had been digested with BamHI. The resulting recombinant molecule pHis-nDiCP 945 was transformed into E. coli to form recombinant cell E. coli :pHis-nDiCP 945 .

Example 3

This Example describes the production in bacteria of a filariid nematode cysteine protease protein of the present invention. This Example also discloses an antibody preparation produced in response to the parasitic helminth protein.

Recombinant cell E. coli :pHis-nDiCP 945 , produced as described in Example 2, was cultured in shake flasks containing an enriched bacterial growth medium containing 0.1 mg/ml ampicillin and 0.1% glucose at about 32° C. When the cells reached an OD 600 of about 0.4, expression of D. immitis nDiCP 945 was induced by addition of about 0.5 mM isopropyl-β-D-thiogalactoside (IPTG), and the cells cultured for about 3 hours at about 32° C. Protein production was monitored by SDS PAGE of recombinant cell lysates, followed by Coomassie blue staining, using standard techniques. Recombinant cell E. coli :pHis-nDiCP 945 produced a fusion protein, denoted herein as PHIS-PDiCP 314 , that migrated with an apparent molecular weight of about 37 kD.

Immunoblot analysis of recombinant cell E. coli :pHis-nDiCP 945 lysates indicated that the about 37 kD protein was able to bind to a T7 tag monoclonal antibody (available from Novagen, Inc., Madison, Wis.) directed against the fusion portion of the recombinant PHIS-PDiCP 314 fusion protein.

The PHIS-PDiCP 314 histidine fusion peptide was separated from E. coli proteins by nickel chelation chromatography and an imidazole gradient. Immunoblot analysis of the total E. coli :pHis-nDiCP 945 lysate, column eluate and column void volume using the T7 tag monoclonal antibody indicated that the PHIS-PDiCP 314 37 kD protein bound to the nickel column and was eluted using an imidazole gradient.

A rabbit was immunized twice with PHIS-PDiCP 314 that had been purified by chelation chromatography. Antisera collected from this rabbit was denoted anti-PHIS-PDiCP 314 antisera. Immunoblot analysis of E. coli :pHis-nDiCP 945 lysates indicated that the anti-PHIS-PDiCP 314 antisera selectively bound to the PHIS-PDiCP 314 37 kD protein produced by the recombinant cell.

Example 4

This Example describes the production of a D. immitis L3 cysteine protease protein of the present invention in a eukaryotic cell.

Recombinant molecule pVL1393-nCP 945 , containing a D. immitis L3 cysteine protease nucleic acid molecule operatively linked to baculovirus polyhedron transcription control sequences was produced in the following manner. An about 945 nucleotide DNA fragment containing nucleotides spanning from about nucleotide 253 through about nucleotide 1197 of SEQ ID NO:1, called nDiCP 945 , was PCR amplified from recombinant molecule pβgal-nDiCP 1298 , described in Example 1, using the following primers: a sense primer BvCP sen (5′ CGCGGATCCTATAAATATGAAAAAATTAGAAACC 3′ (SEQ ID NO:10) and an antisense primer BvCP ant 5′ CGCGGATCCTTATATGGGGAATGAAGC 3′ (SEQ ID NO:11), which have BamHI sites (in bold) incorporated into the primers. The N-terminal primer was designed from the nucleic acid sequence of nDiCP 1298 with modifications to enhance expression in the baculovirus system.

The PCR product was digested with BamHI restriction endonuclease, gel purified and subcloned into baculovirus shuttle plasmid pVL1393 (available from Invitrogen Inc., San Diego, Calif.) that had been cleaved with BamHI. The resulting recombinant molecule, denoted herein as pVL1393-nDiCP 945 was co-transfected into S. frugiperda Sf9 cells (donated by the Colorado Bioprocessing Center, Fort Collins, Colo.) with linear wild type baculovirus DNA (AcMNPV) and insectin cationic 1s liposomes (available from Invitrogen) to form: S. frugiperda :pVL1393-nDiCP 945 . The proper orientation of the pVL1393-nDiCP 945 insert was verified by restriction enzyme mapping.

The resulting recombinant virus, denoted vBV-nDiCP 945 , was cultivated for increased production of recombinant virus and expression of PDiCP 314 was verified by immunoblot blot analysis. Immunoblot analysis using rabbit anti-PHIS-PDiCP 314 antisera (described in Example 3) demonstrated that insect cells infected with recombinant baculovirus vBV-nDiCP 945 expressed a protein detected in the culture lysates. This protein encoded by nDiCP 945 , namely PDiCP 314 , migrated with an apparent molecular weight of about 35 kD. Sf9 cells infected with wild type baculovirus did not express this 35 kD protein.

Example 5

This Example demonstrates the use of a D. immitis L3 cysteine protease nucleic acid molecule of the present invention to obtain a nucleic acid molecule of another filariid nematode.

A. nOvCP 291

O. volvulus L3 cysteine protease nucleic acid molecule nOvCP 291 was obtained in the following manner. D. immitis L3 cysteine protease nucleic acid molecule nDiCP 1298 , produced as described in Example 1, was cleaved with EcoRI and XhoI to produce two fragments of about 850 bp and 450 bp that were gel purified and mixed hexamer labeled with Amersham's Megaprime DNA Labeling system (available from Amersham Corp., Arlington Heights, Ill). These labeled fragments (i.e., nDiCP 850 and nDiCP 450 ) were used to screen an O. volvulus L3 cDNA library for plaques having nucleic acid molecules that could form stable hybrids with the D. immitis nucleic acid molecules under stringent hybridization conditions. Approximately 70,000 plaques from an O. volvulus L3 cDNA library were screened with the mixed hexamer labeled D. immitis heterologous probe using standard hybridization techniques as described by Sambrook et al., ibid. Numerous positive signals were identified from this primary hybridization screen. These regions were plugged, and the phage pools were screened further by plaque hybridization screening using the same mixed hexamer labeled D. immitis nDiCP 12 fragment probe. One L3 cDNA clone was plaque purified, excised, and subcloned into pBluescript (available from Stratagene). Plasmid DNA was analyzed by EcoRI restriction digestion and found to contain an insert of about 290 nucleotides.

The insert of the plasmid was sequenced as described in Example 1 and determined to have about a 291-nucleotide nucleic acid sequence, represented herein as SEQ ID NO:5. A nucleic acid molecule consisting of SEQ ID NO:5 is referred to herein as nOvCP 291 . Translation of SEQ ID NO:5 indicated that nOvCP 291 includes an open reading frame spanning from about nucleotide 2 through about nucleotide 217 with a stop codon nucleotides spanning from about nucleotide 218 through about nucleotide 220, followed by a 3′ untranslated region spanning from about nucleotide 221 through about nucleotide 291. The open reading frame encodes a protein of about 72 amino acids, referred to herein as POvCP 72 , the amino acid sequence of which is represented herein as SEQ ID NO:6. Nucleic acid molecule nOvCP 216 consists of the coding region of POvCP 72 , the nucleic acid sequence of which is represented herein as SEQ ID NO:7.

Comparison of the O. volvulus POvCP72 amino acid sequence with the corresponding amino acid sequence of D. immitis PDiCP 398 indicate that the two sequences share about 67% identity. About 77% identity was found between the amino acid sequence encoded by approximately 284 nucleotides of the coding region plus the proposed 3′ untranslated region of the O. volvulus nOvCP 291 and the amino acid sequence of the 3′ end of D. immitis nDiCP 1298 . Comparison of the amino acid sequence of the coding region of O. volvulus nOvCP 216 and the corresponding region of D. immitis nDiCP 1298 indicate that the two regions share about 80% identity.

About 65% identity was found between about 66 amino acids of O. volvulus POvCP 72 and the amino acid sequence of the 3′ end of cathepsin L-like proteinase from liver fluke, Fasciola hepatica . About 65% identity was found between about 62 amino acids of O. volvulus POvCP 72 and the amino acid sequence of the 3′ end of cathepsin L proteinase from parasitic trematode, Schistosoma mansoni . About 63% identity was found between approximately 65 amino acids of O. volvulus POvCP 7 2 and the amino acid sequence of the 3′ end of chick cathepsin L (EC 3.4.22.15).

B. nOvCP 1306

An O. volvulus cysteine protease nucleic acid molecule, referred to herein as nOvCP 1306 , was produced by PCR amplification using the following method. Antisense primer ovcpa-1, having nucleic acid sequence 5′ CAT GTT CCC CTT ATT TC 3′ (represented herein as SEQ ID NO:12) was used in combination with the sense vector primer T3X, having nucleic acid sequence 5′ CAT GTT CCC CTT ATT TC 3′ (represented herein as SEQ ID NO:13), to PCR amplify, using standard techniques, a DNA fragment from an O. volvulus L3 cDNA library (Lambda Uni-ZAP XR, reference number SAW94WL-OvL3) constructed by S. Williams and W. Lu (Smith College, Northampton, Mass.). A resulting PCR product of about 1272 bp, referred to herein as nOvCP 1272 , was gel purified and cloned into the pCRII Vector® System (obtained from Invitrogen), and subjected to standard DNA sequencing techniques.

A composite nucleic acid sequence including an O. volvulus cysteine protease apparent full-length coding region, referred to herein as nOvCP 1306 , was deduced using the nucleic acid sequence of nOvCP 291 and nOvCP 1272 , and is denoted herein as SEQ ID NO:14. The nucleic acid sequence SEQ ID NO:14 includes an open reading frame spanning from about nucleotide 20 through about nucleotide 1222, with a first ATG codon spanning from about nucleotide 20 through about nucleotide 22 and a termination (stop) codon spanning from about nucleotide 1223 through about nucleotide 1225. SEQ ID NO:14 also encodes a putative hydrophobic signal peptide of about 23 amino acids, the coding sequence spanning from about nucleotide 20 through about nucleotide 88.

Translation of SEQ ID NO:14 indicates that SEQ ID NO:14 encodes a protein of about 407 amino acids, denoted herein as POvCP 408 , having the deduced amino acid sequence represented herein as SEQ ID NO:15.

The open reading frame extending from nucleotide 20 of nOvCP 1306 up to the stop codon is a nucleic acid molecule of about 1203 nucleotides, denoted herein as nOvCP 1203 and represented by SEQ ID NO:16, which encodes a protein of about 401 amino acids, denoted herein as POvCP 401 , having the deduced amino acid sequence represented herein as SEQ ID NO:17. Based on SEQ ID NO:17, POvCP 401 has a calculated molecular weight of about 45.8 kD and an estimated pI of about 9.4.

Comparison of the O. volvulus POvCP 401 amino acid sequence with the corresponding amino acid sequence of D. immitis PDiCP 398 indicates that the two sequences share about 49% identity. Comparison of the O. volvulus nOvCP 1306 nucleic acid sequence with the corresponding nucleic acid sequence of D. immitis nDiCP 1298 indicates that the two sequences share about 71% identity. Analysis of the amino acid sequence of POvCP 401 indicated significant conservation of residues involved in proteolytic processing of the pre-protein to form a processed pro-protein.

A BLAST homology search indicated that about 330 amino acids of POvCP 401 was most similar in amino acid sequence to the amino acid sequence of a rabbit cathepsin K precursor (OC-2 protein, Genbank Acc. No. P43236), there being about 44% identity between the two regions.

A BLAST homology search indicated that about 1005 nucleotides of the O. volvulus nOvCP 1306 nucleic acid sequence was most similar in nucleic acid sequence to the nucleic acid sequence of a Spirometra mansonoides cysteine protease (Genbank Acc. No. U51913), there being about 51% identity between the two regions.

Taken together, these examples clearly indicate that knowledge of the nucleic acid sequence of D. immitis and O. volvulus cysteine protease nucleic acid molecules of the present invention enables the identification and isolation of additional filariid nematode nucleic acid molecules of the present invention.

Example 7

This Example describes the production of a eukaryotic recombinant cell and use of that cell to produce a eukaryotic version of a D. immitis L3 cysteine protease protein of the present invention.

Recombinant molecule pKB3poly-nDiCP 1071 , containing a D. immitis L3 cysteine protease nucleic acid molecule spanning nucleotides from about 127 through about 1197 of SEQ ID NO:1 operatively linked to the vaccinia virus p11 late promoter transcription control sequences was produced in the following manner. The pKB3poly poxvirus shuttle vector was created by modifying a region of plasmid pKB3 (P 11 -type) (pKB3 (P 11 -type) plasmid (described in U.S. Pat. No. 5,348,741, by Esposito et al., issued Sep. 20, 1994) such that the initiation codon linked to the p11 promoter was mutated and additional unique polylinker restriction sites were added. The resulting poxvirus vector, referred to as pKB3poly, requires the insert DNA to provide the ATG initiation codon when inserted downstream of the p11 promoter. The pKB3poly vector is designed such that foreign DNA cloned into the polylinker region of pKB3poly vector will recombine into the thymidine kinase (TK) gene of wildtype poxvirus.

In order to subclone a D. immitis L3 cysteine protease nucleic acid molecule into the pKB3poly expression vector, an about 1071 nucleotide D. immitis L3 cysteine protease nucleic acid molecule-containing fragment spanning from about nucleotide 127 through about nucleotide 1197 of SEQ ID NO:1, called nDiCP 1071 , was PCR amplified from recombinant molecule pβgal-nDiCP 1298 , described in Example 1, using the following primers: a sense primer EukCP sen 5′ CGGGGTACCAGGAAATATGACGAGACTTAC 3′ (SEQ ID NO:18) and an antisense primer EukCP ant 5′ CGGGGTACCTTATATGGGGAATGAAGC 3′ (SEQ ID NO:19), which have Asp718I sites (in bold) incorporated into the primers.

The PCR product was digested with Asp718I restriction endonuclease, gel purified and subcloned into the pKB3poly shuttle vector which had been digested with Asp718I restriction endonuclease, treated with calf intestinal phosphatase and gel purified to produce recombinant molecule pKB3poly-nDiCP 1071 . The proper orientation of the insert was verified by restriction digest mapping.

In order to produce a recombinant raccoon poxvirus capable of directing the production of PDiCP 356 , BS-C-1 African green monkey kidney cells (obtained from American Type Culture Collection (ATCC), Rockville, Md.) were infected with wild type raccoon poxvirus RCN CDC/V71-I-85A) (obtained from Dr. Joseph Esposito; Esposito et al, 1985 , Virology 143,230-251) and then transfected with the pKB3poly-nDiCP 1071 vector DNA by calcium phosphate precipitation to form recombinant cell BSC1:pKB3poly-nDiCP 1071 . The resulting recombinant virus, denoted Rcn-nDiCP 1071 , was plaque purified twice in RAT-2 rat embryo, thymidine kinase mutant cells (available from ATCC) in the presence of bromodeoxyuridine (BUDR) to select for TK recombinants. The TK recombinant virus was plaque purified once and then cultivated in BS-C-l cells without BUDR. Expression of the D. immitis L3 cysteine protease recombinant protein was monitored by SDS PAGE of infected BS-C-1 cell lysates, followed by immunoblot analysis with the rabbit anti-PHIS-PDiCP 314 antisera (described in Example 3). Recombinant cell BSC1:pKB3poly-nDiCP 1071 produced a eukaryotic version of PDiCP 356 that migrated with an apparent molecular weight of about 42 kD and that was selectively bound by rabbit anti-PHIS-PDiCP 314 antisera.

Example 8

This Example describes the production of a eukaryotic recombinant cell and use of that cell to produce a multivalent virus vaccine capable of expressing both D. immitis L3 cysteine protease and D. immitis PLA2 proteins (D. immitis PLA2 nucleic acid molecules and proteins are described in PCT International Publication No. WO 94/15593, published Jul. 21, 1994).

Recombinant molecule p11-nDiCP 1071 /pSyn-nDicP2 453 , containing two D. immitis nucleic acid molecules operatively linked to separate promoters was produced in the following manner. p11/pSyn pox virus shuttle vector was created by modifying a region of plasmid pKB3poly shuttle plasmid (described in Example 7) in the following manner. A double stranded linker molecule was synthesized to contain the poxvirus promoter pSyn (see, for example, Davison et al, 1990 , Nuc. Acids Res . 18, 4285-4286) as follows. Two complimentary oligonucleotides, EJH016 and EJH017 were synthesized and have the following nucleotide sequence: EJH016 5′ GATCCAATTGGATCAGCTTTTTTTTTTTTTTTTTTGG CATATAAATAAG 3′ (SEQ ID NO:20) with the BamHI cohesive end indicated in bold; and EJH017 5′ GTACCTTATTTATATGCC AAAAAAAAAAAAAAAAAAGCTGATCCAATTG 3′ (SEQ ID NO: 21) with the Asp718I cohesive end indicated in bold. The two oligonucleotides were annealed to create a 45 nucleotide double stranded region with a 4-nucleotide single stranded BamHI cohesive terminus on one end and a 4-nucleotide single stranded Asp718I cohesive terminus on the other end to facilitate directional cloning of this fragment into the unique BamHI and Asp718I sites of pKB3poly shuttle plasmid. The resulting poxvirus vector, referred to as p11/pSyn, requires the insert DNA to provide the ATG initiation codon when inserted downstream of the psyn or the P 11 promoter. The p11/pSyn vector is designed such that foreign DNA cloned into the polylinker region of p11/pSyn vector will recombine into the TK gene of wildtype poxvirus.

A recombinant molecule containing (a) a D. immitis PLA2 nucleic acid molecule containing the PLA2 open reading frame (described in WO 94/15593, ibid., operatively linked to pSyn transcription control sequences and (b) a D. immitis L3 cysteine protease nucleic acid molecule spanning nucleotides from about 127 through about 1197 of SEQ ID NO: 1 operatively linked to the vaccinia virus P 11 late promoter transcription control sequences was produced in the following manner.

In order to subclone a PLA2 nucleic acid molecule into p11/pSyn expression vector, a nucleic acid molecule containing the PLA2 open reading frame was cleaved from D. immitis PLA2-nucleic acid molecule-containing vector p76-52H3 (produced as described in Example 15 of WO 94/15593, ibid.) using BamHI restriction endonuclease. The about 453 nucleotide insert DNA (referred to as Rcn-nDiPLA2 453 ) was treated with Klenow enzyme to create blunt ends resulting in the production of nucleic acid molecule nRcnDiPLA2 453 , gel purified and subcloned into the p11/pSyn shuttle vector, which had been restricted with Asp718I and EcoRI restriction endonuclease, treated with Klenow enzyme to create blunt ends, treated with calf intestinal phosphatase and gel purified, to produce recombinant molecule p11/pSyn-nDiPLA2 453 . The proper orientation of the Rcn-nDiPLA2 453 insert was verified by restriction digest mapping.

In order to subclone a D. immitis L3 cysteine protease nucleic acid molecule into p11/pSyn-nDiPLA2 453 expression vector, a L3 cysteine protease nucleic acid molecule-containing fragment was cleaved from D. immitis pKB3poly-nDiCP 1071 DNA (produced as in Example 7), by Asp718I restriction endonuclease. The about 1071 nucleotide insert DNA (referred to as Rcn-nDiCP 1071 ) was treated with Klenow enzyme to create blunt ends resulting in the production of nucleic acid molecule nRcnDiCP 1071 , gel purified and subcloned into the p11/pSyn-nDiPLA2 453 shuttle vector, which had been digested with SmaI restriction endonuclease, treated with calf intestinal phosphatase and gel purified, to produce recombinant molecule p11-nDiCP 1071 /pSyn-nDiPLA2 453 . The proper orientation of the Rcn-nDiCP 1071 insert was verified by restriction digest mapping.

In order to produce a recombinant raccoon poxvirus capable of directing the production of PDiCP 356 and PDiPLA2 150 , BS-C-1 African green monkey kidney cells (obtained from ATCC, Rockville, Md.) were infected with wild type raccoon poxvirus RCN CDC/V71-I-85A and then transfected with the p11-nDiCP 1071 /pSyn-nDiPLA2 453 vector DNA to form recombinant cell BSC1:p11-nDiCP 1071 /pSyn-nDiPLA2 453 . The resulting recombinant virus, denoted Rcn-nDiCP 1071 -nDiPLA2 453 , was cultivated in RAT-2 rat embryo, thymidine kinase mutant cells as described in Example 7. Expression of the cysteine protease and the PLA2 recombinant proteins was monitored by SDS PAGE of infected BS-C-1 cell lysates, followed by immunoblot analysis with the rabbit anti-PHIS-PDiCP 314 antisera and rabbit anti-PHIS-PDiPLA2 antisera (produced as described in Example 14 of WO 94/15593, ibid.).

Example 9

This Example describes the production of a D. immitis L3 cysteine protease protein using a eukaryotic cell transformed with a D. immitis L3 cysteine protease nucleic acid molecule of the present invention.

Recombinant molecule pCMV-nDiCP 1071 , containing a D. immitis L3 cysteine protease nucleic acid molecule spanning nucleotides from about 127 through about 1197 of SEQ ID NO:1 operatively linked to the cytomegalovirus (CMV) promoter transcription control was produced in the following manner. The pCMV expression vector was produced as follows. Vector pRc/RSV (available from InVitrogen) was cleaved by restriction enzyme PvuII, and the 2963-base pair PvuII fragment gel purified. That fragment was self-ligated to form vector pRc/RSV(Pvu), which contains a Rous Sarcoma Virus (RSV) long terminal repeat, a multiple cloning site, a bovine growth hormone polyadenylation sequence, a bacterial origin of replication and an ampicillin resistance gene.

Expression vector PVXRC was produced by introducing a HindIII fragment containing the cytomegalovirus (CMV) intermediate early promoter and first intron (i.e., Intron A) into pRc/RSV(Pvu) that had been cleaved by HindIII. Expression vector pCMV was produced by introducing a HindIII/SspI fragment containing the CMV intermediate early promoter and first intron (i.e., Intron A) into pRc/RSV(Pvu) that had been cleaved by HindIII and NruI.

In order to subclone a D. immitis L3 cysteine protease nucleic acid molecule into the pCMV expression vector, D. immitis L3 cysteine protease nucleic acid molecule-containing fragments were PCR amplified as described in Example 7. The about 1071 PCR product (referred to as nDiCP 1071 ) was digested with Asp718I restriction endonuclease, gel purified and subcloned into the pCMV expression vector which had been restricted with Asp718I restriction endonuclease, treated with calf intestinal phosphatase and gel purified to produce recombinant molecule pCMV-nDiCP 1071 . The proper orientation of the insert was verified by restriction mapping.

To produce the recombinant cell line BHK:pCMV-nDiCP 1071 , pCMV-nDiCP 1071 was transfected into Baby Hamster Kidney Cells (BHK) (obtained from ATCC, Rockville, Md.) was performed by standard procedures. Briefly, six-well polystyrene tissue culture plates were seeded with about 3×10 5 cells/well in 2 mls of MEM NEAA Earle's salts (available from Irvine Scientific, Santa Ana Calif.) with 100 mM L-glutamine, 5% FBS (complete growth media). Cells were grown to 80% confluence (about 48 hr). The recombinant molecules to be transfected were purified using Qiagen tips (available from Qiagen Inc., Chatsworth, Calif.) per manufacturer's instructions. Using polystyrene plates, about 2 μg of each recombinant molecule was mixed with about 100 μl OptiMEM (available from Gibco BRL). About 15 μl Lipofectamine (available from Gibco BRL) was mixed with about 100 μl OptiMEM. The Lipofectamine mixture was then added to the recombinant molecule mixture and incubated at room temperature for about 30 min. After incubation, about 800 μl OptiMEM was added and the entire mixture overlaid onto the BHK cells that had been rinsed with OptiMEM. Cells were incubated at 37° C., 5% CO 2 , 90% relative humidity. The transfection mixture was then removed and replaced with about 2 mls complete growth media.

Transfected cells were incubated at 37° C., 5% CO 2 , 90% relative humidity for about 24 hr and harvested. The media was removed, the cells washed twice with about 2 mls PBS and scraped off the plate in about 1.5 ml PBS. The cells were pelleted by centrifugation, the PBS removed and the cells frozen.

Expression of the D. immitis L3 cysteine protease recombinant protein was monitored by SDS PAGE of infected BHK cell lysates, followed by immunoblot analysis with the rabbit anti-PHIS-PDiCP 314 antisera. Recombinant cell BHK:pCMV-nDiCP 1071 produced a eukaryotic version of PDiCP 356 , that migrated with an apparent molecular weight of about 42 kD, that was bound selectively by rabbit anti-PHIS-PDiCP 314 antisera.

Example 10

This Example describes the expression of D. immitis L3 cysteine protease native protein in different developmental stages of the D. immitis life cycle.

Total protein was prepared from 0 hour third stage larvae (0-hr L3), 48 hour third stage larvae (48-hr L3), 6 day fourth stage larvae (6-day L4), and adult male or adult female worms. Immunoblot analysis of these antigen preparations with rabbit anti-PHIS-PDiCP 314 antiserum (produced as described in Example 3) indicated that the D. immitis native cysteine protease protein migrated at about 22 kD and was detected only in the 48-hr L3 and 6-day L4 larval preparations. This 22 kD size of the D. immitis native protein is consistent with the predicted size of a mature protein resulting from processing of the amino acid sequence represented by PDiCP 356 . Cleavage of an amino terminal propeptide sequence to form an active enzyme is characteristic of peptidases of the papain family. The deduced amino acid sequences represented by nDiCP 1071 (described in Example 7) contains conserved amino acid residues present in the propeptide sequences, namely the ERFNN motif including glutamine (E) at position 64, arginine (R) at position 68, phenylalanine (F) at position 72, asparagine (N) at position 75 and asparagine (N) at position 83.

Example 11

This example discloses the production of a recombinant cell of the present invention.

Recombinant molecule pHis-nOvCP 1203 was produced in the following manner. An about 1203 nucleotide DNA fragment containing nucleotides spanning from about nucleotide 89 through about nucleotide 1222 of SEQ ID NO:14, called nOvCP 1203 , was polymerase chain reaction (PCR) amplified from nOvCP 1306 , described in Example 5, using the following primers: primers EXPCP5′5′ ACTGGATCCGCAAGTGCAACAGCTACGAGAAG 3′ (SEQ ID NO:22) (BamHI site in bold) and EXPCP3′5′ TAAGGTACCTTATATGGGTATTGAAGCCAACGTTGCGATGTGGCACATGTTCCCCTTATT TCG 3′ (SEQ ID NO:23) (KpnI site in bold). The PCR product was digested with BamHI restriction endonuclease, gel purified and subcloned into expression vector lambdaP R /T 2 ori/S10HIS-RSET-A9 (produced as described in Example 7 of PCT Publication No. WO 95/24198, published Sep. 14, 1995) that had been digested with BamHI and KpnI. The resulting recombinant molecule pHis-nOvCP 1203 was transformed into E. coli to form recombinant cell E. coli :pHis-nOvCP 1203 .

Example 12

This Example describes the production in bacteria of an O. volvulus L3 cysteine protease protein of the present invention.

Recombinant cell E. coli :pHis-nOvCP 1203 was produced as described in Example 11, was cultured in shake flasks containing an enriched bacterial growth medium containing 0.1 mg/ml ampicillin and 0.1% glucose at about 32° C. When the cells reached an OD 600 of about 0.4, expression of 0. volvulus nOvCP 1203 was induced by addition of about 0.5 mM isopropyl-β-D-thiogalactoside (IPTG), and the cells cultured for about 3 hours at about 32° C.

Immunoblot analysis of recombinant cell E. coli :pHis-nOvCP 1203 lysates indicated that an about 47 kD protein was able to bind to a T7 tag monoclonal antibody (available from Novagen, Inc., Madison, Wis.) directed against the fusion portion of the recombinant pHIS-POvCP 401 fusion protein.

Example 13

This Example describes additional nucleic acid and deduced amino acid sequences of a filariid nematode cysteine protease nucleic acid molecule of the present invention, the isolation of which was described in Example 1. It should be noted that nucleic acid sequencing technology is not entirely error-free, and as such variations between sequences may be due to a number of factors, including, but not limited to, sequencing errors. Thus, the nucleic acid sequences presented herein, represent apparent nucleic acid sequences of nucleic acid molecules encoding a D. immitis CP protein of the present invention.

D. immitis L3 cysteine protease nucleic acid molecule nDiCP 1298 , isolated as described in Example 1, was submitted to additional DNA sequence analysis which indicated that the nucleic acid molecule apparently included an extra six nucleotides—this nucleic acid molecule is hence referred to as nDiCP 1304 . Nucleic acid molecule nDiCP 1304 was sequenced using the Sanger dideoxy chain termination method, using the PRISM™ Ready Dye Terminator Cycle Sequencing Kit with AmpliTaq™ DNA Polymerase, FS (available from the Perkin-Elmer Corporation, Norwalk, Conn.). PCR extensions were done in the GeneAmp™ PCR system 9600 (available from Perkin-Elmer). Excess dye terminators were removed from extension products using the Centriflex™ Gel Filtration Cartridge (available from Advanced Genetics Technologies Corporation, Gaithersburg, Md.) following their standard protocol. Samples were resuspended according to ABI protocols and were run on a Perkin-Elmer ABI PRISM™ 377 Automated DNA Sequencer. DNA sequence analyses, including the compilation of sequences and the determination of open reading frames, were performed using either the DNAsis™ program (available from Hitachi Software, San Bruno, Calif.) or the MacVector™ program (available from the Eastman Kodak Company, New Haven, Conn.). An about 1304 nucleotide consensus sequence of the entire nDiCP 1304 nucleic acid molecule was determined and is denoted herein as SEQ ID NO:32 (the coding strand) and SEQ ID NO:35 (the complementary strand). The nucleic acid sequence SEQ ID NO:32 includes an open reading frame spanning from about nucleotide 1 through about nucleotide 1200. While not being bound by theory, the nDiCP 1304 nucleic acid sequence contains an apparently partial coding region, truncated at the 5′ end. The first in-frame codon spans nucleotides from about 1 through about 3 and the stop codon spans nucleotides from about 1198 through about 1200 of SEQ ID NO:32. A putative polyadenylation signal (5′ AATAAA 3′) is located from about nucleotide 1271 through about nucleotide 1276 of SEQ ID NO:32.

Translation of SEQ ID NO:32 yields a protein of about 400 amino acids, denoted PDiCP 400 , the deduced amino acid sequence of which is represented herein as SEQ ID NO:33. The nucleic acid molecule comprising the coding region encoding PDiCP 400 is referred to herein as nDiCP 1200 , the nucleic acid sequence of which is denoted herein as SEQ ID NO:34 (the coding strand) and SEQ ID NO:36 (the complementary strand). Analysis of SEQ ID NO:33 suggests the presence of a partial N-terminal signal peptide encoded by a stretch of amino acids spanning from about amino acid 1 through about amino acid 14, or from about amino acid 1 through about amino acid 18. Secreted proteins with these putative signal peptides removed are denoted herein as PDiCP 386 and PDiCP 382 , respectively. PDiCP 386 and PDiCP 382 are encoded by nucleic acid molecules of about 1158 and about 1146 nucleotides, respectively, denoted herein as nDiCP 1158 and nDiCP 1146 , respectively.

The very highly conserved catalytic residues of members of the papain family of cysteine peptidases are a cysteine at amino acid position 25 (C25) and a histidine residue at position 159 (H159) of the mature, processed peptide. Other amino acid residues important for catalysis include a glutamine at position 19 (Q19) and asparagine at position 175 (N175). The numbering of these amino acids correspond to the amino acid position of the mature Carica papaya papain sequence (Genbank Acc. No. M15203).

Based on a homology alignment of the PDiCP 400 deduced amino acid sequence with known papain amino acid sequences, the predicted mature protein resulting from the processing of the PDiCP 400 CP protein, referred to as PDiCP 215 and denoted herein as SEQ ID NO:38, would begin with the leucine at about residue 186 of PDiCP 400 . This predicted processing point is analogous to the predicted processing point for the PDiCP 356 CP protein, at about leucine 144 of SEQ ID NO:25, as described in Example 1. PDiCP 215 is encoded by a nucleic acid molecule of about 645 nucleotides denoted herein as nDiCP645, the nucleic acid sequence of which is represented by SEQ ID NO:37 (the coding strand) and SEQ ID NO:39 (the complementary strand). PDiCP 215 contains the papain family conserved residues believed to be involved in catalysis, namely, a cysteine at residue 25 (C25), a histidine at residue 162 which corresponds to the H159 of papain, a glutamine at position 19 (Q19) and an asparagine at residue 183 which corresponds to the N175 of papain. In addition, many members of the papain C1 family contain a proline residue at position 2 of the mature, processed enzyme. The PDiCP 215 amino acid sequence SEQ ID NO:38 has a proline at position 2 of the predicted mature enzyme.

Homology searches of the non-redundant protein sequence database were performed through the National Center for Biotechnology Information using the BLAST network. The protein sequence database includes+SwissProt+PIR+SPUpdate+GenPept+GPUpdate. Using BLAST, amino acid sequences SEQ ID NO:33 and SEQ ID NO:38 were found to have significant homology to certain cysteine proteases. SEQ ID NO:33 and SEQ ID NO:38 were aligned to the homologous sequences using the Maximum Matching program contained in the DNAsis™ software package, with the default settings. SEQ ID NO:33 (in its entirety) was found to be most closely homologous, at about 38 percent identity, to Bos taunts cathepsin L (Genbank Accession No. X91755), and SEQ ID NO:38 was found to be most closely homologous, at about 50 percent identity, to Gallus gallus cathepsin L (PIR Accession No. 86218).

Example 14

This Example describes the production of additional D. immitis L3 cysteine protease proteins of the present invention in eukaryotic cells.

A. Recombinant molecule pVL1392-nDiCP 1206 , containing a D. immitis L3 cysteine protease nucleic acid molecule operatively linked to baculovirus polyhedron transcription control sequences was produced in the following manner. An about 1206 nucleotide DNA fragment containing nucleotides spanning from about nucleotide 1 through about nucleotide 1203 of SEQ ID NO:32 (plus an added ATG initiation codon), called nDiCP 1206 (SEQ ID NO:43), was PCR amplified from recombinant molecule pβgal-nDiCP 1298 , described in Example 1, using the following primers: a sense primer, MM01 5′ CGCAGATCTA TGCTTCGATT CATTGC 3′ (SEQ ID NO:40) and an antisense primer MM02 5′ CGCAGATCTT TATATGGGGA ATGAAGC 3′ (SEQ ID NO:41), which have BglII restriction sites (in bold) incorporated into the primers. The N-terminal primer was designed from the nucleic acid sequence of nDiCP 1304 with modifications to enhance expression in the baculovirus system.

The PCR product was digested with BglII restriction endonuclease, gel purified and subcloned into baculovirus shuttle plasmid pVL1392 (available from Invitrogen) that had been cleaved with BglII. The resulting recombinant molecule, denoted herein as pVL1392-nDiCP 1206 was co-transfected into S. frugiperda Sf9 cells (Available from Invitrogen) with BaculoGold™ baculovirus DNA (AcMNPV) (available from Pharmingen, San Diego, Calif.) to form S. frugiperda :pVL1392-nDiCP 1206 . The proper orientation of the pVL1392-nDiCP 1206 insert was verified by restriction enzyme mapping.

The resulting recombinant virus, denoted vBV-nDiCP 1206 , was cultivated for increased production of recombinant virus and expression of PDiCP 401 (SEQ ID NO:44) was verified by immunoblot analysis. Immunoblot analysis using rabbit anti-PHIS-PDiCP 314 antisera (described in Example 3) demonstrated that insect cells infected with recombinant baculovirus vBV-nDiCP 1206 expressed a protein detected in the culture lysates. This protein encoded by nDiCP 1206 , namely PDiCP 401 , migrated with an apparent molecular weight of about 55 kD. Sf9 cells infected with wild type baculovirus did not express this 55 kD protein.

B. Recombinant molecule pVL1393/nPLA2-nDiCP 726 , containing a D. immitis L3 cysteine protease nucleic acid molecule fused in-frame with the 66 nucleotide signal segment of the D. immitis PLA2 gene, and operatively linked to baculovirus polyhedron transcription control sequences, was produced in the following manner. An about 648 nucleotide DNA fragment containing nucleotides spanning from about nucleotide 556 through about nucleotide 1203 of SEQ ID NO:32, was PCR amplified from recombinant molecule pβgal-nDiCP 1298 , described in Example 1, using the following primers: a sense primer MM03 5′ CCGGAATTCT ACTGCCAAAA TATGTTGATT GG 3′ (SEQ ID NO:42) and an antisense primer MM02 5′ CGCAGATCTT TATATGGGGA ATGAAGC 3′ (SEQ ID NO:41), which have EcoRI and BglII restriction sites (in bold), respectively, incorporated into the primers.

The PCR product was digested with EcoRI and BglII restriction endonucleases, gel purified and subcloned into baculovirus shuttle plasmid pVL1393/PLA2 which had been cleaved with EcoRI and BglII. This vector is a modification of vector pVL1393 in which a 66 nucleotide signal segment of the D. immitis PLA2 gene was inserted such that nucleic acid molecules could be fused in-frame downstream of the signal segment. The fusion comprises a 10-nucleotide portion of the pVL1393 polylinker region. This signal segment is disclosed as nucleotides 7-72 of SEQ ID NO:1 in pending U.S. patent application Ser. No. 08/482,304, by Grieve, et al., filed Jun. 7, 1995, which is incorporated herein by reference in its entirety. The nucleotide sequence of the coding region (including the stop codon)of nPLA2-nDiCP726 is presented herein as SEQ ID NO:45. The resulting recombinant molecule, denoted herein as pVL1393/nPLA2-nDiCP 726 was co-transfected into S. frugiperda Sf9 cells (Available from Invitrogen) with BaculoGold™ baculovirus DNA (AcMNPV) (available from Pharmingen) to form: S. frugiperda :pVL1393/nPLA2-nDiCP 726 .

The resulting recombinant virus, denoted vBV-nPLA2-nDiCP 726 , is cultivated for increased production of recombinant virus and expression of PPLA2-PDiCP 241 (SEQ ID NO:46) (215 amino acids encoded by nDiCP 645 , 22 amino acids encoded by the PLA2 signal segment, and 4 amino acids encoded by the pVL1393 polylinker and primer MM03) is verified by immunoblot analysis, using rabbit anti-PHIS-PDiCP 314 antisera.
