SPECIFICATION

CROSS REFERENCE TO RELATED APPLICATIONS This application 1s a cont1nuat1on-1n-part of US patent application 08/281,702 filed 27 July 1994.

FIELD OF THE INVENTION

This invention relates to a vaccine against herpes virus for treatment and prevention of the development of several herpes virus infections and/or atherosclerotic plaques. More particularly the invention relates to a herpes vaccine containing peptides encoded by parts of herpes virus DNA with homology to alpha-subunlts of human G proteins and that acts as a prophylaxis against pathogenic development of several herpes Infections and/or atherosclerotic plaque In a mammalian subjected susceptible thereto.

BACKGROUND OF THE INVENTION It is generally accepted that atherogenesis is triggered by primary injury to the endotheϋal lining of the arterial walls. This injury is believed to be the result of exposure of the underlying smooth muscle cells to several factors of non-infectious origin (hormones, low density lipoproteins, growth factors, among others). The prevailing view is that human atherosclerosis (AS) is a pleiotropic process with various causes. See Ross, R., The Pathogenesis of Atherosclerosis: An Update, New England J. Med.,314, 488 to 500 (1986). A fundamentally new etiological factor: herpes virus infection was reported by Fabricant et al, who demonstrated that chickens infected with Marek Disease Virus (MDV) have an unusually high incidence of atherosclerotic plaque (ASP) in the arteries. See Fabricant, C.G. et al, Virus-Induced Cholesterol Crystals, Science . 181, 566 to 567 (1973); and Fabricant, C.G. et al, Virus-Induced Atherosclerosis, J. EXD. Med.. 148, 335 to 340 (1978). Since that time data have been accumulated suggesting herpes virus in AS in humans. It was shown that different herpes viruses can alter smooth muscle cells lipid metabolism and Induce cholesterol and cholesterol ester accumulation in these cells. See Fabricant, C.G. et al, Herpes Virus Infection Enhances Cholesterol and Cholesterol Ester Accumulation in Cultured Arterial Smooth Muscle Cells, Am. J. Pathol. 105, 176 to 184 (1981); Fabricant, C.G. et al, Herpes Virus-Induced Atherosclerosis In Chickens, Fed.

In addition the DNA of various erpesviruses showed positive hybridization with ASP DNA; see Benditt, E.P. et al, Viruses In the Etiology of Atherosclerosis, Proc. Natl. Acad. Sc1.. 80, 6386 to 6389 (1983); Pyrzak, R. et al, Detection of Specific DNA Segments of Marek's Disease Herpes Virus In Japanese Quail Susceptible to Atherosclerosis, Atherosclerosis. 68, 77 to 85 (1987); Petrie, B.L. et al, Nucleic Acid Sequences of Cytomegalovirus In Cultured Human Arterial Tissue, J.

Pathol.. 134, 1151 to 1157 (1989).

No systematic attempts to demonstrate a viral presence in ASP by direct isolation of Infectious HSV from ASP and by detection of viral replication in ASP by Electron Microscopy have been reported. A viral presence in ASP would explain the presence of HSV-like DNA in ASP, and redirect research to determine the molecular mechanisms of viral involvement in etiology of atherosclerosis. In such a case, the possibility of a contamination of ASP in the blood vessels by HSV also has to be excluded. None of the above references deals with the preparation of a vaccine against any form of the herpes virus. The following reference deals with the preparation of a herpes vaccine against Marek's Disease Herpes-Virus in chickens: Fabricant, J. et al, Vaccination Prevents Atherosclerosis Induced by Marek's disease Herpesvirus, College of Veterinary Medicine and Medicine, Cornell University, Ithaca and New York, N.Y. The reference appeared as an abstract 1n the Federation of American Societies for Experimental Biology, 65th Annual Meeting, Atlanta (1981).

The vaccine employed against Marek's Disease Herpesvirus in chickens was derived from Turkey herpesvirus (HVT). There Is no Indication that a vaccine against atherosclerosis caused by human herpes virus could be prepared. There 1s certainly no suggestion to employ a herpes vaccine containing homologous peptide sequences to those of the viral DNA found in strains of the herpes virus that effect humans.

U.S. Patent 4,038,381 discloses a vaccine for the prevention and treatment of vascular conditions, comprising a combination of a tuberculosis antigen with an antiherpetic vaccine. There is no suggestion to employ the four polypeptides of the present invention as the active ingredients in the vaccine. The reference also states that the individual tuberculosis antigen and antiherpetic vaccine had no known per se ability in the prevention or treatment of vascular disease.

OBJECT OF THE INVENTION It 1s the object of the invention to provide a universal vaccine as a prophylaxis against pathogenic development of several herpes infections and/or atherosclerotic plaque in a mammalian subject susceptible thereto. SUMMARY OF THE INVENTION We have found such a vaccine that is effective as a prophylaxis against pathogenic development of several herpes infections and/or atherosclerotic plaque in mammalian subjects, including humans. The vaccine contains four new peptides as described herein below in the indicated proportions:

20 25 in combination with a pharmaceutically acceptable Inert vaccine carrier such as normal saline or a physiological oil (e.g. corn oil, sunflower oil).

Preferably each of the four polypeptides 1s present in the compositions in equal proportions by weight: that Is the compositions preferably contain 25% of each of the four polypeptides.

The compositions are prepared by incorporating each of the four polypeptides in the pharmaceutically acceptable inert vaccine carrier such as normal saline or a physiological oil in an adequate concentration of said polypeptides. Preferably there is present 1.0 to 100 μg of each polypeptlde per ml of pharmaceutical composition. More preferably one dose of vaccine (1 ml) contains equal parts (20 μg) of each of the 4 polypeptides. Thus the preferred total amount of polypeptides in one dose of vaccine is 80 μg.

Since each of the polypeptides 1s Itself a new compound, each of them, individually, as well as collectively, is considered to be part of the Invention as well.

Also contemplated to be within the scope of the invention is a method of prophylaxis of pathogenic development of several herpes virus infections and/or atherosclerotic plaques 1n a mammalian subject susceptible thereto which comprises the step of administering to said mammalian subject, a therapeutically effective amount of the pharmaceutical composition containing the four polypeptide sequences as described hereinabove. The herpes infections whose development can be prevented include Herpes Simplex I, Herpes Simplex II, Cytomegalovins, Epstein-Barr Virus, Herpes Zoster and Kaposi's Sarcoma. The compositions may preferably be administered to a mammalian subject parenterally, such as by Injection. More preferably the compositions are administered by subcutaneous, intramuscular, intra- arterial, intravenous or intradermal

Injection. A preferred dosage of the compositions is 1 ml every 20 days administered in a series of 6 Intramuscular Injections. The full cycle of treatment may consist of 2 or 3 such courses with 3 month intervals in between.

Use of an adjuvant, for Instance Inorganic gels such as alum, aluminum hydroxide or aluminum phosphate that increase antigenie response, is optional in the compositions.

Preparation of the Vaccine against Atherosclerosis

The vaccine may be prepared by recomblnant DNA techniques by chemical synthesis or by automated solid phase synthesis. When preparing the vaccine by recombinant DNA techniques the following steps are employed:

Recombinant DNA Synthesis

1. Accumulation of Virus Particles

For isolation of the fragments of DNA that encode peptides having Seq ID 2 and Seq ID 6, it Is necessary to accumulate Herpes Simplex Virus Type 1, and for isolation of the fragments of DNA that encode peptides having Seq ID 4 and Seq ID 8, it is necessary to accumulate Human Cytomegalovirus. Herpes Simplex Virus 1 and Human Cytomegalovirus are each cultivated in diploid human embryonic lung cells (HECL).

Tissue Cultures For Isolation of Herpes Simplex Virus 1 and Human Cytomegalovirus, it is necessary to use diploid human embryonic lung cells (e.g. sejni-continuous cells). These cells are derived from embryonic lung tissue and following initial dispersal, they can be redispersed and regrown many times (30 to 50 times). Human embryonic lung tissue, which can be obtained from embryos of 10 to 12 weeks, provide a most valuable source for harvesting a number of different herpes viruses, including Herpes Simplex Viruses and Human Cytomegalovirus.

Semi-continuous cells have a normal chromosome count (diploid) and show the phenomenon of contact inhibition. An inoculum of each virus isted above 1s placed on the onolayer and allowed to absorb for 1 hour. It is then removed and fresh medium 1s added. Cultures are incubated at 37*C and they are inspected regularly by microscopy for evidence of virus growth. The culture medium is normally changed on the day after inoculation to minimize the effect of toxins that may persist in the inoculum, and is then replaced periodically to replenish the supply of nutrients for the cells. Cultures are incubated for various lengths of time depending on the virus. While the cytopathic effects of a concentrated inoculum of herpes virus may appear overnight, a low level of cytomegalovirus may take 3 to 4 weeks to appear.

The cells infected by herpes viruses may be cultivated in suspension also. For inoculation of the tissue cultures to prepare the peptide vaccines, the following viruses may be used:

Herpes Simplex Type 1 (Human herpesvirus 1, Herpesvirus homines type 1) ATCC VR-539, Strain Maclntyre.

Cytomegalovirus ATCC VR-538 Strain: AD-169.

Note the DNA sequences assigned Seq ID numbers 1, 3, 5, and 7 are the gene sequences containing the codons to obtain the peptides having Seq ID Nos. 2, 4, 6, and 8. The DNA fragments having Seq ID Nos 1,3,5, and 7 are regarded as novel intermediate compounds that constitute part of the present Invention.

This same oligonucleotide may also be found in the complete short unique region 2 with partial terminal and inverted repeats in DNA, HSV 1, Strain 17. The oligonucleotide of Seq ID 3 1s the part of the Human Cytomegalovirus (Strain AD 169) complete genome (from base pair 70001 up to base 80100). Its 75 nucleotides are located from bp 2342 up to 2416 in this region of the Human Cytomegalovirus gene Strain AD=169 according to Human Cytomegalovirus, Viridae, DS-DNA Enveloped Viruses, Herpesvlridae, Betaherpesvirinae.

The oligonucleotide of Seq ID 3 1s in the Human Cytomegalovirus F fragment DNA encoding DNA Polymeraseycoprotein B also and has homology with DNA from the following viruses:

(a) Epstein-Barr Virus, artifactual joining of B95-8 complete gene and the sequences from ragi of the large deletion found in B95-8 (from base pair 70001 to 80100) about 70%.

Isolation of the ollgonucleo ldes sequences from the viral DNA that code for the four peptides Indicated above.

The viral DNA 1s isolated from corresponding viral suspension obtained from HELC infected by Herpes Simplex 1 or Human Cytomegalovirus (see above about cell cultures and virus strains), purified by agarose gel electrophoresis (AGE) according to Myers, R.M. et al, "Detection and Localization of Single Base Changes by Denaturing Gradient Gel Electrophoresis; Methods Enzymol. 155:501 to 527 (1987) and Myers et al, "In Genome Analysis: A Practical Approach" (Ed. K. Davies) p. 95 IRL Press, Oxford (1988), treated by restriction enzymes and subjected by polyacrylamide gel electrophoresis.

The isolation of oligonucleotide with Seq ID 1 from Herpes Simplex virus type I Immediate early (IE) gene 3 for transcriptlonal activator IE 175 (- ICP4) is produced after treating DNA by restriction enzyme Ncol with recognition sequence CGATGG. This procedure according to PAAG, EF gives the polynucleotide with 2308 pair of bases (from 2637 up to 4935 position) with the actual fragment located from 3760 up to 3844 position.

The isolation of oligonucleotide with Seq ID 3 from HCMV (strain AD169) complete genome 1s produced after treating of DNA by restriction enzyme Bst E III with recognition sequence GATC. This procedure after PAAG, EF gives the polynucleotide with 2182 pair of base - from 715 to 2898 position - with the actual fragment from 2342 up to 2416 position.

The isolation of oligonucleotide with Seq. ID5 from HSVI (LAT) is produced after treating of DNA by restriction enzyme Nco 1 with recognition sequence CCATGG. This procedure after PAAG, EF gives the polynucletide with 1737 pair of base -from 659 up to 2396 position - with actual fragment from 2255 up to 2332 position.

The isolation of oligonucleotide with Seq ID 7 from HCMV - short unique region, short repeats, and part of long repeat is produced after treating of DNA by restriction enzyme Nco 1 also. This procedure after PAAG, EF gives the polynucleotide with 4807 pair of base with actual fragment from 5340 up to 5424.

The structures of the Herpes Simplex Virus Type I Immediate Early (IE) Gene 3 for Transcriptional Activator IE 175; HCMV (Strain AD 169); HSVI (LAT); and HCMV - Short Unique Region are known in the art and may be found in EMBL-37.

The construction of recombinant plasmid DNA for expression of the four peptides, with Seq Nos. 2, 4, 6 and 8.

All 4 ollgonucleotldes are introduced into a polylInker of plasmid pRSET with sites of restriction, including Nco 1 and Bst E III. This plasmid may be used to transform E.Coli (AB 109 strain). For this aim bacteria are treated with CaCl₂ which makes their membranes slightly permeable (competent bacteria). The transformed bacteria are then selected by growing them on a medium containing ampicillin. pRSET Is a commercial multicopy expressing vector with a high level of protein expression.

Chemical Synthesis The four sequences having the formulae Seq. Nos. 2,4,6 and 8 may also be prepared by direct peptide synthesis that is well known in the art according to the syntheses employed in The Peptides. Schroeder and Luebke, Vol. I, Methods of Peptide Synthesis, Academic Press (1965). Preferably each of the four polypeptides having Seq Nos. 2,4,6 and 8 are synthesized starting from the amino terminal acid and forming the peptide bond between the carboxy terminal of the given amino acid and the amino terminal of the next given amino acids. This procedure is carried out until all of the amino acids needed to make each of the four peptides are formed into whole chains.

Where it is necessary to employ an amino-protecting group to protect an N-terminal amino substituent to carry out the synthesis of one or more of the four above-mentioned peptides, the approaches of pages 3 through 51 of The Peptides may be employed. Where It 1s necessary to employ a carboxy-protecting group to protect either a C-terminal carboxy group or a carboxy group forming part of a side chain (I.e. Glu, Asp) to carry out the synthesis of one or more of the four above-mentioned polypeptides, the methods of page 52 through 75 of the reference are e ployed.

Glycine and alanine are relatively simple amino acids common to the presently claimed peptides. Where it 1s necessary to block the amino terminal, carbobenzoxy groups are employed. Where it is necessary to block the carboxy terminal, a benzyl ester 1s formed. See pages 137 and 138 of The Peptides.

In fact the information regarding blocking the C- and N-terminals of simple amino acids such as glycine and alanine without highly reactive side chains is still highly relevant to the blocking of all amino acids involved in the synthesis of the peptides of the present invention.

One amino acid common to all four peptides of the Seq Nos 2, 4, 6 and 8 is arginine. Arginine has a guanido group on its side chain and sometimes this group may be responsible for undesired side reactions. Pages 167 through 174 of The Peptides discusses peptide synthesis using a number of different blocking groups to protect the guanido side chain. Pages 175 and 176 discuss peptide synthesis involving arginine where the guanido side chain need not be blocked. Another amino add that 1s well represented among the four peptides of this invention is proline. Proline is a heterocyclic amino acid with an i ino functional group. Where It 1s necessary to block the imino group, pages 146 through 148 of The Peptides provides details.

Serine is an amino acid present in three of the four new peptides. Serine contains a side chain that Includes a hydroxy group. In some situations the hydroxy group may undergo undesired side reactions. The Peptides on pages 207 through 214 describes peptide synthesis using serine with and without protecting groups for the hydroxy group on the side chain.

Threonine 1s another amino add present in three of the four new polypeptides that also contains a side chain having a hydroxy substituent. In some situations the hydroxy group may undergo undesired side reactions. T e Peptides on pages 214 through 216 describes peptide synthesis using threonine with and without protecting groups for the hydroxy group on the side chain.

Tryptophan 1s an amino add present in the new peptide of Seq. ID No. 8. Tryptophan 1s an indole and thus contains an indole nitrogen that can undergo undesired side reactions. Pages 148 through 150 of The Peptides describes peptide synthesis using tryptophan.

Glycine and alanine are relatively simple amino acids common to the presently claimed peptides. Where it 1s necessary to block the amino terminal, carbobenzoxy groups are employed. Where it 1s necessary to block the carboxy terminal, a benzyl ester is formed

Where it is necessary during peptide synthesis to facilitate the reaction of the C-terminal of a given amino acid or peptide, the activated ester technique as described in The Peptides on pages 97 to 108 may be employed.

Solid Phase Synthesis of the Four Peptides

The synthesis of each of the four peptides with the Sequence ID Nos. 2, 4, 6 and 8 according to the instant patent application was carried out. Each of the four peptides was produced by the Automation of Solid Phase Synthesis with the following High Performance Liquid Chromatography (HPLC). See AmlnoTech. 1991.

Determination of Immunogenic Activity of the Peptide Vaccine 1. Coupling Peptides to Protein Carriers With Glutaraldehyde Glutaraldehyde is a bifunctional coupling agent that couples amino groups on the peptide to amino groups on the protein carrier Keyhole Limpet Hemocyanin (KLH). For preparing each complex of peptide-KLH with glutaraldehyde, it was necessary to carry out the following procedures:

(1) 20 mM glutaraldehyde were prepared;

(2) KLH was dissolved in water;

(3) Each of the four peptides was added to the water individually;

(4) The glutaraldehyde was added dropwise with stirring to the water over the course of 5 minutes at room temperature. Stirring of the solution was continued for another 30 minutes. The solution became yellow.

(5) Glycine was then added to the solution to block any unreacted glutaraldehyde and allowed to remain for 30 minutes;

(6) Excess peptide and reagent were then removed by either exhaustive dialysis in phosphate-buffered saline (see Kagan & Glick 1979. "Oxyitodn", Methods of Hormone

Radioimmunoassay. B.B. Jaffe & H.R. Behrman, eds. pp 328 to 329, Academic Press, NY).

2. Immunization of Rabbits on the Basis of a Special Schedule of Injections by a Mixture of Equal Amounts of All Peptides

For the study to determine the immunogenic activity of the four peptides, a mixture of equal amounts of all four of the peptides with Seq. ID numbers 2, 4, 6 and 8 with KLH was used. Immunization of two rabbits (designated R76 and R77) was carried out according to the following Immunization schedule:

(a) first bleeding;

(b) day 1, first injection;

(c) day 8, second injection;

(d) day 24, third Injection;

(e) day 40, fourth Injection;

(f) day 55, fifth injection;

(g) from 70th day, second and final bleeding The immunization dose was 0.5 mg per Injection.

3. ELISA Titration of Rabbit's Iαnunosera with Synthetic Peptides

In the present case for the measurement of antibodies in rabbit sera, each of the four peptide reagents (which are the same four peptides that are the active Ingredients in the vaccine) was fixed to a specific plastic πricroplate, Incubated with each - test serum (from Rabbit R76 or R77) (obtained both before and after administering the vaccine) at dilutions of 1:30,000, 1:10,000: 1:3,000 and 1:1,000), washed, and then reinoculated with an anti-immunoglobulin labelled with an enzyme, namely, horseradish peroxidase.

The enzyme activities were measured by adding the substrate for the enzyme and estimating the color reaction in a spectrophotometer. The amount of antibody bound to the absorbed peptide reagents is proportional to the enzyme activity. Once the substrate for the enzyme is added the enzymatic activity is determined and the amount of unknown antibody is determined as a function of the measured enzyme activity.

The ELISA was carried out using the following steps: 1. A 96-well plate was coated with 20 ug/ml of free peptide in 0.01 M sodium phosphate buffer, pH 7.2 containing 0.1 M NaCl (PBS) (50 ul / well, 4 overnight),

2. The plate was washed twice with PBS and block the wells with TANA's^R blocking solution for one hour at 37* C,

3. The wells were incubated with diluted serum (using 1.0% BSA / PBS for_^dilution, 37^* C for 2 - 4 hours),

4. Each well was washed four times with PBS, and then Incubated with 1 : 3,000 diluted goat antirabbit IgG-horseradish peroxidase conjugate (TANA Lab., using 1.0% BSA / PBS for dilution) for 1 hour.

5. Each well was washed four times with PBS, and then incubated with TANA's^R calorimetrlc ELISA substrate (tetra methylbenzene / H202 solution),

6. The enzyme reaction was stopped with TANA's" ELISA-stopplng buffer (diluted phosphoric acid),

7. The plates were read using 450 n .

On the base of this technique these data were obtained:

FIG. 2. Binding of rabbit #76 serum to first peptide with Seq.

ID No. 2.

FIG.3. Binding of rabbit #77 serum to first peptide with Seq.

ID No. 2.

FIG.4. Binding of rabbit #76 serum to second peptide with Seq. ID No.4.

FIG. 5. Binding of rabbit #77 serum to second peptide with Seq. ID No. 4.

FIG. 6. Binding of rabbit #76 serum to third peptide with Seq. ID No. 6. FIG. 7. Binding of rabbit #77 serum to third peptide with Seq. ID No. 6.

FIG. 8. Binding of rabbit #76 serum to fourth peptide with Seq. ID No. 8.

FIG. 9. Binding of rabbit #77 serum to fourth peptide with Seq. ID No. 8.

In both rabbit sera (R76 and R77) the high levels of antibodies against each of our four peptides were determined in contrast with these sera before Immunization.

On the basis of ELISA titrations, it was found that two rabbits produced high tlter antibodies against each of the four tested peptide reagents with Seq. ID No. 2, 4, 6 and 8. The results are presented in Figures 2 through 9. Note the large difference In the Immunogenic activity In the rabbit blood before and after the peptide-containing vaccine was administered to the rabbits.

In two of such sera from Immunized rabbit N76 (R76) and immunized rabbit N77 (R77) and in pre-immune (normal) sera (R78) in the Laboratory of Microbiological Associates, Inc. (MA) the level (titers) of antibodies were determined against:

Herpes Simplex Virus 1 (HSVI) - on the basis of MA'sELISA

Herpes Simplex Virus 2 (HSV2) - on the basis of Whittaker kit,

ELISA,

Human Cytomegalovirus (HCMV) - on the basis of Whittaker kit,

ELISA,

Varicella Zoster Virus (VZV) on the basis of MA's IFA, Epstein - Bar Virus (EBV) - on the basis of MA's IFA. Titers were determined by comparison with the mean + 99% confidence Interval for control (normal, pre-immune) serum R78 (See: Tables 5 through 8).

As one can see, strong differential reactivity was obtained for:

R76 - against HSV-1 + HSV-2 and HCMV,

R77 - against HSV-1 + HSV-2 and HCMV.

Neither antibody showed reactivity against EBV (VCA) antigen.

Although reactivity against VZV was relatively strong for R76 and R77, the R78 titer was also elevated and, therefore, did not allow low tltered differential results.

At present we are providing some additional data concerning the antibody titers In sera of rabbits who have been immunized with the polypeptide vaccine according to the present invention.

After immunization of the rabbits by the polypeptide vaccine containing the four polypeptides we have obtained the next level of specific antibodies against the different herpes viruses in an ELISA test: against Herpes Simplex Virus I 3000 against Herpes Simplex Virus II 3000 against Human Cytomegalovirus 1000 against Epstein-Barr Virus 10,000 against Varicella-Zoster Virus 3,000 against Marek's Disease Virus 10,000. In these experiments we have used the homogenates of cell cultures infected by several herpes viruses (from American Cell Culture Collection) as antigens for ELISA titration.

Thus, the data demonstrate that "antibody titers Increase not only over control after multiple Injections of the pharmaceutical composition..." but also possess the real protective activity of these sera against all actual members of the Herpes Viridae family.

The data presented above show that the new vaccine accordi g to the present invention displays a real Immunogenic activity, and a protective activity and this activity shows the effectiveness of the new peptide -- containing vaccine to stimulate herpes antibody production against all herpes viruses. The vaccine may be designated as a polyvalent or universal herpes vaccine

EFFICACY OF THE PEPTIDE-CONTAINING VACCINE TO PREVENT THE DEVELOPMENT OF ATHEROSCLEROTIC PLAQUE Background Information It is known in the art that an increase of G proteins in the blood (Gs proteins) that stimulate the production of cyclic AMP prevents the development of atherosclerotic plaque. The new vaccine containing the polypeptides with Seq. ID Nos. 2, 4, 6 and 8 prevents the development of atherosclerotic plaque by stimulating the production of Gs proteins.

Atherogenesis is a consequence of persistent herpes virus infection development in blood vessel walls. In the course of this development, synthesis of a considerable number of virus-specified regulator proteins (transcriptional factors) takes place in the vessel walls. Some of these regulator proteins repress viral DNA replication and transcription, thus preventing a chronic herpes viral infection from becoming an acute infection. Owing to the homology between certain sections of the alpha subunit of the Gs protein gene and those of the genes of a number of herpes viruses, individual virus-specific transcription factors bind with GGC-GGC-GGC sections in the alpha subunit of the Gs protein gene and suppress the transcription of this gene. This in turn, decreases translation and synthesis of the Gs protein. A decrease in Gs protein production reduces cyclic AMP formation. This causes a reduction of the synthesis of cholesterol ether hydrolase, which in turn increases atherogenesis.

The antibodies generated In the rabbit in response to the Injection of our polypeptlde vaccine bind with one of the transcription factors described above, this factor being related to the GGC-GGC-GGC sites in the Gs protein gene. These antibodies prevent the emergence of a complex between the Gs protein gene site and the abovementioned transcription factor. The antibodies prevent the inhibitory influence of the persistent herpes virus infection on the synthesis of Gs proteins, thus mitigating the extent of atherogenesis.

Experimental Section The prevention of the formation of the DNA-protein complex containing DNA from the Gs protein gene and protein from the herpes transcription factor by means of the antibodies generated by administration of our peptide vaccine to rabbits is illustrated with the results of the model experiments described below. The study of DNA-protein interaction has been conducted by the shift-mobility assay method.

Shift Mobility Assay

Al. Extraction of Alpha-Protein from Nuclei

Purified nuclei from normal blood vessel endothelium and blood vessel endothelium with atherosclerotic plaques (ASP) were extracted with 0.35 M NaCl. Purified nuclei were pelleted by low-speed centrifugation and re-suspended by vortexing to a final DNA concentration of 0.4 mg/ml in 0.35 M NaCl, 5 M Na-EDTA, 10 M 2-mercaptoethanol, 10 mM Tris-HCl (pH 7.5) containing the five protelnase inhibitors (Phenylmethylsulfonyl fluoride (PMSF), antipain, leupeptin, chymostatin, and pepstatin A) at the concentration used in the nuclei isolation. After 30 minutes at 30*C with occasional vortexing, the suspension was centrifuged at 10,000 x g for 15 minutes. The supernatant containing the alpha-protein was used either immediately or after storage at -70*C in the presence of 15% glycerol.

These alpha-proteins are new factors of herpes virus transcription and are different from the heretofore known factors of herpes virus transcription such as Spll, Ergl, Wtl and others. The new transcriptional factors have the ability to make the stable DNA-protein complex in vitro in the experimental model system (as described hereinbelow) and in the human organism as well as with a specific site on the alpha-subunit of the Gs proteins.

A2. Preparation of DNA-Fragments with GGC-Sites from the Promoter Region of Mouse Ribosome Protein Gene

Fragments containing GGC sites were isolated from the promoter region of mouse ribosome protein gene following complete digestion of purified mouse DNA with either H1nd III or Mbo II restriction enzymes. The fragments were purified separately by preparative electrophoresis in 6% polyacrylamide el ted from the gels, and thereafter separately end-labeled with 32P by T4 polynucleotide klnase and gamma-32P-ATP, following a treatment with bacterial alkaline phosphatase (Maxam and Gilbert, 1980). The labelled DNA was purified by extractions with chloroform:Isopropanol (24:1 by weight) in the presence of 1% SOS, 1M NaCl and ethanol- precipitated 1n the presence of 10 mg/ml of linear polyacrylamide as a carrier. Equal amounts of the 32P-counts of the Hind III and MboII produced fragments of DNA were then mixed together to yield the final DNA sample with the GGC-GGC-GGC sites.

A3. Detection of the DNA-Protein Interactions by the Shift Mobility Assay

The "DNA-Protein" interactions were investigated by the Shift- Mobility Assay on a low ionic strength 4% polyacrylamdide gel (See FIG. 10).

As it 1s shown, pure DNA-fragment DNA (see A2) In the absence of any addition of protein extract, migrates in the gel in a discrete band. See FIG. 10, Lane "a", while in the presence of protein extract (extracted from the purified nuclei of blood vessel endothelium with ASP), most of the DNA failed to enter the gel. See FIG. 10, Lanes "b" and "c". The same result was shown with a mixture of "DNA" plus "ASP" plus rabbit sera where the rabbit sera did not contain the antibodies against the herpes peptides generated by the rabbit upon administration of the polypaptide vaccine. See FIG. 10, Lanes "d" and "e". In the presence of an aliquot of extracts of purified nuclei of human blood endothelum without ASP (normal endothelium "NE") the "DNA" migrated to an intermediate extent. See Lanes "f" and "g" of FIG. 10.

In the presence of "ASP" and rabbit Immune sera ("IS") in dilution 1:50 to 1:10 "DNA" migrates as a discrete band as pure DNA (see FIG. 10, Lanes "1" through "1" and compare with the results 1n Lane "a", which shows pure "DNA" without protein or Immune sera). In the case of the addition to the complex of "DNA" plus "ASP" the "IS" 1n dilution 1:100 and 1:50, the "DNA" migrates to an Intermediate extent. See FIG. 10, Lane "h"

Further analysis of the shift mobility assay as shown in Fig. 101s as follows:

Fig. 10 shows the electrophoretic mobility in 4& polyacrylamide gel of the "DNA-GGC sites fragments", with alpha proteins of nuclei from human blood vessel endothelium (with and without ASP) and with rabbit sera (with and without antibodies generated by administration of the present polypeptide vaccine to rabbits).

Lane "a" "DNA-GGC fragment" (25,000 cpm, 2.5 ng of DNA) in the absence of added protein extract and any sera.

Lanes "b" through "e" "DNA-GGC site fragments" in the same concentration + aliquot of the extracts of purified nuclei from human blood vessel endothelium cells with ASP (b,c) and + aliquot of the normal (pre¬ immune) rabbit sera - N76(d) and N77(e) 1n dilution 1:2.

Lanes "f" and "g" "DNA-GGC- sites fragments" in the same concentration + aliquot of the extracts of purified nuclei from normal human blood vessel endothelial cells without ASP.

Lane "h" "DNA-GGC sites fragment" in the same concentration + a mixture of aliquots of the extract of purified nuclei from endothelial blood vessel cells with ASP + aliquot of the mixture of the post-immune rabbit sera N76 and N77 In a dilution of 1:100.

Lanes "I" through "1" are the same situation as in Lane "h", but the mixture of Immune sera was used 1n a dilution of 1:50(1); l:30(j); l:20(k); and 1:10(1).'

These data show that the usage of Immune rabbit sera against several herpesvirus peptides can prevent formation of the complex between DNA GGC-GGC-GGC binding sites on the mouse ribosomal protein gene which shares this binding site In common with the genes expressing the Gs proteins and the protein extract from the nuclei of blood vessel endothelium with "ASP" and consequently prevents the development of "ASP".

In the experiment presented above the antibodies In the immune rabbit sera decrease the formation of the DNA-protein complex by more than 90% according to the data in Figure 10 and that such a decrease in the formation of the complex will facilitate the in vivo expression of the Gs protein genes to produce Gs proteins which in turn leads to increased cyclic AMP production and less formation of atherosclerotic plaque (ASP);

We performed an additional experiment using gel retardation to analyze the mobility of the "DNA-GGC sites fragment" in 5% PAAG. The results are shown in Fig. 11.

According to Fig. 11, the immunosera number 77 (N4) and number 76 (N6) (with dilution 1:20) had decreased the formation (amount) of DNA- protein complex between DNA-GGC-fragment labelled by 32P and the alpha- protein nuclei from human blood vessel cells with ASP in comparison with the amount of the DNA-protein complex when the corresponding pre-immune sera N5 and N7 were employed Instead. Both of the Immune sera Nl and N2 as well as the preimmune sera 76 (N3) had no influence on the formation (amount) of the DNA-protein complex, when such sera were used in a dilution of 1:100.

These additional data confirm that the use of immune rabbit sera containing antibodies generated by administration of the present peptide vaccine, can prevent the formation of a DNA-protein complex between DNA-GGC site fragments characteristic of the gene that expresses the Gs proteins and protein extract the nuclei of blood vessel endothelium with ASP, characteristic of the herpes transcriptional factor, and consequently the polypeptide vaccine can prevent the development of ASP.
