PROLACTIN AS A VACCINE ADJUVANT
Background of the Invention The use of vaccines to prevent diseases in humans, farm livestock, sports animals and household pets is a common practice, and considerable effort has been, and is being, made to extend this practice to cover a more extensive array of diseases to which these patients are subject. For example, the use of rabies vaccine in animals is by now commonplace, and efforts are being made to obtain suitable vaccines to immunize animals against other diseases.
One problem that frequently is encountered in the course of active immunization is that the antigens used in the vaccine are not sufficiently immunogenic to raise the antibody titer to sufficient levels to provide protection against subsequent challenge or to maintain the potential for mounting these levels over extended time periods. Another problem is that the vaccine may be deficient in inducing cell-mediated immunity which is a primary immune defense against bacterial and viral infection.
In order to obtain a stronger humoral and/or cellular response, it is common to administer the vaccine in a formulation containing an adjuvant, a material which enhances the immune response of the patient to the vaccine. The most commonly used adjuvants for vaccines are oil preparations and alum. The mechanisms by which such adjuvants function are not understood, and whether or not a particular adjuvant preparation will be sufficiently effective in a given instance is not predictable.
In addition, with the advent of gene therapy it has been reported that some success has been accomplished with using genes or "naked DNA" as vaccines. However, as with some of the conventional vaccines, the immune response obtained was insufficient to afford immunization.
Accordingly, there is a need for additional effective adjuvant preparations which are suitable for potentiating vaccines for animals in general, and particularly in humans.
Summary of the Invention
The present invention relates to a composition for enhancing the immune response of an animal to an infectious disease vaccine wherein the composition comprises prolactin. Preferably, the composition is human prolactin and the animal to be vaccinated is, as well, human.
The present invention further relates to a composition for enhancing the immune response of an animal to an infectious disease vaccine wherein the composition comprises prolactin cDNA. Human prolactin cDNA is preferred. In another aspect, the invention relates to a method of enhancing the immune response of a subject animal to an infectious disease vaccine comprising co-administering an effective amount of prolactin or prolactin cDNA along with a vaccine.

Detailed Description of the Invention
Definitions
As used herein, "prolactin" refers to a polypeptide obtained from tissue cultures or by recombinant techniques and other techniques known to those of skill in the art, exhibiting the spectrum of activities characterizing this protein. The word includes not only human prolactin (hPRL), but also other mammalian prolactin such as, e.g., mouse, rat, rabbit, primate, pig and bovine prolactin. The amino acid sequence of a recombinant hPRL is shown in Figure 1. The recombinant PRL (r-PRL) is preferred herein.
The term "recombinant prolactin", designated as r-PRL, preferably human prolactin, refers to prolactin having comparable biological activity to native prolactin prepared by recombinant DNA techniques known by those of skill in the art. In general, the gene coding for prolactin is excised from its native plasmid and inserted into a cloning vector to be cloned and then inserted into an expression vector, which is used to transform a host organism. The host organism expresses the foreign gene to produce prolactin under expression conditions.
As used herein, the term "adjuvant" has its conventional meaning, i.e., the ability to enhance the immune response to a particular antigen. Such ability is manifested by a significant increase in immune-mediated protection. Furthermore, the term "genetic adjuvant" refers to prolactin cDNA which comprises the complement to the DNA sequence encoding the prolactin protein as defined above. The sequence for prolactin cDNA is shown in Figure 2.
General Method
Formulations containing prolactin for adjuvant purposes are most conveniently administered by intramuscular or subcutaneous injections or intraperitoneal although other methods of administration are possible.
Standard formulations are either liquid injectables or solids which can be taken up in suitable liquids as suspensions or solutions for injection. Suitable excipients are, for example, water, saline, dextrose, glycerol, ethanol, and so forth. Nontoxic auxiliary substances, such as wetting agents, buffers, or emulsifiers may also be added.
Sustained and continuous release formulations are of considerable variety and could be used in the method of the present invention, as is understood by those skilled in the art. Prolactin can be administered separately from the vaccine or in combination with the vaccine. When prolactin is combined with the vaccine, the composition administered contains an immunogen that is effective in eliciting a specific response to a given pathogen or antigen, a pharmaceutically acceptable vaccine carrier and an immunopotentiating amount of prolactin. The vaccine will normally be administered per manufacturer's instructions. Other adjuvants may be administered either with the vaccine or together with the prolactin. Prolactin will typically be used to enhance the protection afforded by animal or human vaccines that are considered "weak" (i.e., provide diminished protection in terms of level, extent, and/or duration). Examples of such vaccines are bacterins such as Pseudomonas Staphylococcal, Enterotoxin Streptococci, cytomegalovirus, HIV, Bordetella bacterin, Escherichia coli bacterins, Haemophilus bacterins, Leptospirosis vaccines, Moraxella bovis bacterin, Pasteurella bacterin and Vibrio fetus bacterin and attenuated live or killed virus products such as bovine respiratory disease vaccine (infectious bovine rhinotracheitis, parainfluenza-3, respiratory syncytial virus), bovine virus diarrhea vaccine, equine influenza vaccine, feline leukemia vaccine, feline respiratory disease vaccine (rhinotracheitis-calicipneumonitis viruses), canine parvovirus vaccine, transmissible gastroenteritis vaccine, pseudorabies vaccine, and rabies vaccine.
In addition, because we have demonstrated in vitro and in vivo data that indicate that prolactin can enhance the immune response to an immunogen and thereby function as a vaccine adjuvant, it is believed that the exogenous administration of the prolactin gene would result in the expression of prolactin in vivo which would be available to function as an adjuvant to any immunogen whether administered through conventional means or via gene inoculation. The "genetic adjuvant" could be produced by inserting prolactin cDNA into a DNA delivery vehicle (e.g., plasmid vectors, liposomes, viral vectors). This could be accomplished as described by Pellegrini I., et al., Molec. Endocrinolgy, 6, 1023 (1992), Maniatis T., et al., Molecular Cloning: A Laboratory Manual, 2nd Edition, Cold Spring Harbor Press (1989) and Felger P., et al., Proc. Natl. Acad. Sci., 84, 7413, (1991 ). The "genetic adjuvant" is then administered along with either cDNA encoding the immunogen in an appropriate delivery vehicle or "naked" (i.e., solely the cDNA). In addition, the "genetic adjuvant" could be administered along with the immunogen itself. The injection sequence would be optimized per immunogen, i.e., the prolactin cDNA could be co-administered with the immunogen or immunogen cDNA, or administered in advance or subsequent to their administration. It is believed that the prolactin cDNA could be inserted into the same DNA delivery vehicle. Various routes of administration could be used.
EXAMPLE 1
Co-mitogenicity of recombinant human prolactin (r-hPRL)
Peripheral blood lymphocytes (PBL) were isolated from the blood of normal human volunteers by density gradient centrifugation on Ficoll Paque (Pharmacia). Heparinized blood was diluted 3 fold in phosphate-buffered saline (PBS) and centrifuged at 2000 rpm for 20 minutes. The buffy coat, located on the surface of the red blood cell pellet and consisting of white blood cells, was collected and diluted with an equal volume of PBS. The diluted buffy coat was layered on
Ficoll Paque (6 mis of buffy coat on 4 mis of Ficoll Paque in a 15 ml tube) and centrifuged for 30 minutes at 1400 rpm. The PBL layer, found at the Ficoll-plasma interface, was collected and the cells were washed three times in PBS. PBL were then resuspended at 2x106/ml in serum-free AIM-V medium from Gibco and added to the wells of round bottom 96 well microtiter plates in a 100 μl volume (2x105 PBL/well).
A suboptimal dose of the T cell mitogen concanavalin A (Con A; 0.2 μg/ml) was added in a 50 μl volume together with 50 μl of varying concentrations of r-hPRL (0-1000 ng/ml final). Cultures were done in triplicate. The cells were incubated at 37°C/5% CO2 for 72 hours and the amount of proliferation measured by tritiated thymidine incorporation.
Tritiated thymidine (0.5μ Ci/well) was added for the last 18 hours of incubation and cell-associated radioactivity was measured by scintillation counting after harvesting the cells onto glass fiber filters using a Skatron 96 well cell harvester. Results, obtained with cells from different individuals, shown in Table 1 below, indicated that r-hPRL was able to enhance the proliferative response of T lymphocytes to a suboptimal concentration of Con A. This co-mitogenic activity was best observed with r-hPRL concentrations of 1 -10 ng/ml, illustrated in Figure 3.

EXAMPLE 2
Enhancement of antigen-specific proliferation bv r-hPRL
To test the ability of r-hPRL to enhance the proliferative response of human T cells to a specific antigen, PBL were incubated with various concentrations of r-hPRL and streptokinase, a common antigen to which most individuals are exposed. Cultures were performed in triplicate in the wells of 96 well round bottom microtiter plates and consisted of 100 μl PBL (2x105/well), 50 μl streptokinase (25 μg/ml final) and 50 μl of r-hPRL at varying concentrations (0-1000 ng/ml final). Proliferation was measured by tritiated thymidine incorporation after 6 days of culture at 37°C/5%C02-
The results, shown in Table 2 below, indicated that r- hPRL, at a concentration of 1 ng/ml, significantly enhanced streptokinase-induced proliferation.

EXAMPLE 3
Effect of prolactin in enhancing the immune response to an immunogen
Twenty-four 150 gram male Sprague-Dawley rats were divided into 4 groups. The control group received an intraperitoneal injection of 10 μg BSA mixed with alum. The other 3 groups received intraperitoneal injections of 10 μg BSA mixed with alum along with either 180 μg prolactin, 375 μg prolactin or 750 μg prolactin. Tail vein bleeds were taken weekly for 4 weeks and the serum evaluated for antibody to BSA by a Radioimmunosorbent Assay (RIA). The animals were boosted after the 4th bleed with 10μg BSA mixed with alum. Tail vein bleeds were taken over a 7 week period to obtain serum which was evaluated for the development of antibody to BSA by RIA.
Bovine serum albumin (BSA)-specific proliferation of peripheral blood lymphocytes from rats immunized with BSA +/- r-hPRL To measure the effect of r-hPRL on the cellular response of rats immunized with BSA, blood was collected from individual animals sacrificed 101 days after boosting. To isolate peripheral blood lymphocytes (PBL), blood samples were diluted 4 fold in the phosphate-buffered saline (PBS) and centrifuged at 2000 rpm for 20 minutes. The buffy coat was collected and contaminating red blood cells were removed by the addition of Tris-ammonium chloride lysis buffer followed by a 10 minute incubation at 37°C. PBL were then washed twice in PBS and resuspended at 5x106/ml in RPMI-1640 medium supplemented with 100 u/ml penicillin, 100 μg/ml streptomycin, 20 mM Hepes buffer, 2 mM L-glutamine, 5x10" 5 M 2-mercaptoethanol and 5% heat-inactivated fetal calf serum. PBL were added to the wells of flat bottom 96 well microtiter plates in a 100 μl volume (5x10^ cells/well) and cultured in the presence of medium alone (background control) or 1000 μg/ml BSA added in a 100 μl volume. Cultures were done in
triplicate. Proliferation was measured by tritiated thymidine incorporation after 5 days of culture at 37°C/5% Cθ2-
The results indicated that, overall, PBL rats immunized with BSA + 180 μg rhPRL displayed higher levels of BSA- specific proliferation than PBL from rats immunized with antigen alone. This observation suggests that r-hPRL may act to enhance the cellular component of the immune response to an immunizing antigen. Results are compiled in Table 3 below and are illustrated in Figures 5 and 6.
