Altered major histocompatibility complex (MHC) determinant and method of using the determinant

BACKGROUND OF THE INVENTION
This invention relates to an altered major histocompatibility complex (MHC) determinant and to the altered MHC determinant in association with an antigen. This invention also relates to the use of the altered MHC determinant in diagnostic applications and for treating or immunizing a mammal.
The major histocompatibility complex is a series of genes that code for protein molecules responsible for cell-cell recognition and interaction. The MHC of mammalian species contains three groups of genes: class I, class II, and class III. Class I and class II genes code for cell surface recognition molecules. Class III genes code for certain complement components.
The ability of cells to recognize other cells as self or as originating from another genetically different individual (non-self) is an important property in maintaining the integrity of tissue and organ structure. Class I and class II MHC products control recognition of self and non-self. The major histocompatibility system thus prevents an individual from being invaded by cells from another individual. For example, transplants from one individual generally cannot survive in another individual because of histocompatibility differences.
Histocompatibility similarities are required for cellular cooperation in induction of the immune response, and they provide a mechanism to ensure that T cells and B cells of a given individual can recognize each other for cooperation, yet recognize foreign structures at the same time. For instance, T lymphocytes, when presented with an antigen in the proper manner, react in one of two ways: through the generation of T cytotoxic lymphocytes (T.sub.c) or through amplification by T helper cells (T.sub.h) or suppression by T suppressor cells (T.sub.s) of the effects of other T or B cells. In general, T lymphocytes only recognize the antigen and respond to it when it is presented on the surface of antigen-presenting cell. This antigen-presenting cell may vary according to the type of T lymphocyte involved. Thus, in the generation of cytotoxic responses, lymphocytes and possibly macrophages present the antigen to the T.sub.c cells, while in the other types of T response the presenting cell may be a macrophage and perhaps dendritic cells.
T cells need to recognize two structures, a foreign antigen and an MHC gene product, for their subsequent activation. The process of generating T.sub.c cells and a cytotoxic response requires that the antigen be presented to the T cells in association with an MHC class I gene product. On the other hand, for B cells to be activated, binding to the antigen is necessary, plus a second signal usually given by a T.sub.h lymphocyte. However, the T.sub.h lymphocytes require the presentation of the antigen in a processed form by an antigen-presenting cell in the context of an MHC class II determinant.
In the case of B cell activation, it has been established that whatever the antigen-presenting cell is, it must process the antigen before presenting it to the T.sub.h lymphocytes. This involves taking up the antigen, sequestering it in intracellular compartments, and re-expressing the antigen or a portion thereof on the surface of the antigen-presenting cell in association with a class II MHC determinant. The T.sub.h cell must be able to recognize the processed antigen and class II markers on both the antigen-presenting cell and the B cell. When each of these requirements is fulfilled, the B cell will be stimulated to proliferate, which greatly increases the number of cells capable of synthesizing specific antibody. These then differentiate into plasma cells, which secrete large amounts of antibody. A similar response employing class II receptors on T.sub.s suppressor cells and class II MHC markers on macrophages and B cells may be operative in induction of T suppressor activity, which turns off antibody production.
Much remains to be understood of the interactions between antigens and MHC class I and class II molecules, and of the way in which T cell receptors recognize MHC-antigen complexes. For instance, a large proportion of MHC molecules is likely to be occupied by a variety of preexisting (probably endogenous) peptides. This obscures the interpretation of peptide-binding assays and hampers crystallographic studies of peptide-MHC complexes. It would be extremely useful to be able to isolate peptide-free MHC molecules, which could be loaded by a single type of peptide.
In addition, there exists a need in the art for knowledge of the peptide motifs of individual MHC alleles to aid in making T-cell epitope predictions, to aid in synthetic or recombinant vaccine development, and for intervention in autoimmune diseases or graft rejection.
SUMMARY OF THE INVENTION
This invention aids in fulfilling these needs in the art. More particularly, this invention provides a MHC class I determinant comprising .alpha..sub.1, .alpha..sub.2, .alpha..sub.3, and .beta..sub.2 -microglobulin polypeptide domains encoded by a mammalian MHC class I locus. The .alpha..sub.3 domain has a carboxyl terminus, and the .beta..sub.2 -microglobulin domain has an amino terminus that is covalently linked to the carboxyl terminus of the .alpha..sub.3 domain.
This invention also provides a MHC class II determinant comprising .alpha..sub.1, .alpha..sub.2, .beta..sub.1, and .beta..sub.2 polypeptide domains encoded by a mammalian MHC class II locus. The domains are covalently linked to form a polypeptide comprising the .beta..sub.2 -.alpha..sub.2 -.alpha..sub.1 -.beta..sub.1 domains in sequence.
In addition, this invention provides a recombinant DNA molecule comprising the MHC class I determinant or the MHC class II determinant of the invention inserted in a vector.
Further, this invention provides a host transformed with the vector of the invention.
Also, this invention provides a composition comprising an antigen bound to the MHC class I determinant or the MHC class II determinant of the invention.
Moreover, this invention provides a method of eliciting an immune system response in a mammal. The method comprises administering to the mammal an effective amount of the MHC class I or class II determinant of the invention, with or without association with an antigen.
Although native MHC molecules can be highly complicated structures not lending themselves to convenient manipulation, the present invention demonstrates the feasibility of creating MHC-antigen complexes between any of a variety of molecules capable of fulfilling the task of target recognition. These molecules are easier to handle and refold during and after denaturing treatments. These constructs are useful in the analysis of functional interactions between the various domains comprising the MHC molecules.
Moreover, this invention makes it possible to intervene in the functioning of the immune system. The immune system cells are capable of recognizing the altered MHC determinants and compositions of the invention and to respond to the presence of a potential pathogen with an effector appropriate to its lineage, e.g., cytotoxic T lymphocytes would respond by cytotoxic activity against the target, and B lymphocytes are activated to synthesize antibody. Macrophages and granulocytes carry out their effector functions, including cytokine release, phagocytosis, and reactive oxygen generation after intervention by the altered MHC determinants and compositions of the invention. Similarly, with an antigen or peptide portion typical as a marker for tumor cells, the immune system response to the tumor is beneficially elevated. In addition, with an antigen capable of causing recognition of immune cells having an inappropriate reactivity with self-determinants, this invention makes it possible to selectively target cells for destruction.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
The invention concerns construction of functional molecules capable of activating the immune system and capable of presenting antigens to the immune system to elicit an antigenic response. More particularly, it concerns the regulation of the immune system response by presenting antigen via an altered MHC determinant so as to cause T-cells to respond to the determinant or the presented antigen. The invention also concerns a method of immunization and therapy for diseases as varied as AIDS, lupus erythematatosus, multiple sclerosis, toxic shock, and snake bite.
1. Major Histocompatibility Complex ("MHC")
All nucleated cells express class I MHC gene products on their surface. Class II gene products are expressed on some cells, such as B cells and macrophages, but not on other cells. This invention provides an altered major histocompatibility complex determinant of a mammal.
The term "major histocompatibility complex" is abbreviated herein as "MHC". The term is used in describing this invention in a generic sense to refer to the set of genes that code for histocompatibility markers in mammals. Exemplary of the mammalian species from which the altered MHC determinants of the invention can be based are the species identified in Table 1.
TABLE 1______________________________________MHC nomenclature of mammalian species Species MHC designation______________________________________Chimpanzee ChLA Dog DLA Guinea pig GPLA Human HLA Mouse H-2 Pig SLA Rabbit RLA Rat RT1 Rhesus monkey RhLA______________________________________
Where reference is made herein to the MHC of a particular mammalian species, the MHC designation in Table 1 will be employed.
2. Class I and Class II Major Histocompatibility Complex Gene Products
Class I MHC gene products are glycoproteins that are noncovalently bound to a peptide termed .beta..sub.2 -microglobulin, which is abbreviated ".beta..sub.2 m" or ".beta..sub.2 M". The class I component is referred to as the heavy chain and the .beta..sub.2 -microglobulin as the light chain. The orientation of the MHC class I molecule and .beta..sub.2 -microglobulin in a cell membrane is illustrated in FIG. 1.
Referring to the Figure, the heavy chain structure is organized with three exposed domains, .alpha..sub.1, .alpha..sub.2, and .alpha..sub.3, which extend from the cell surface and are attached to a hydrophobic transmembrane domain 1 and a short cytoplasmic anchor segment 2 within the cell. Two of the outer domains (.alpha..sub.2 and .alpha.3) have intrachain disulfide bonds (forming loops with considerable homology with Ig).
The light chain (.beta..sub.2 -microglobulin) shown in the Figure is about the same size as one of the .alpha.domains of the heavy chain. Each domain is immunoglobulin-like, consisting of a folded .beta. pleated sheet structure held together by a disulfide bond at the ends, giving a plane-like surface. The .beta..sub.2 chain folds with the .alpha..sub.3 domain of the heavy chain, and the .alpha..sub.1 and .alpha.2 domains also pair.
The .beta..sub.2 -microglobulin gene is located on a chromosome different from that containing the MHC class I gene product. Its structure is highly conserved, whereas that of the heavy chains varies extensively from one individual to another because of differences in amino acid sequences of the external domains. The polymorphism of the heavy chain is contributed primarily by the .alpha..sub.1 domain and to a lesser degree by the .alpha..sub.2 domain.
The products of the class II genes are less well characterized. In the mouse, the class II gene product (Ia) consists of two polypeptide chains (.alpha.and .beta., FIG. 2). The .alpha.and .beta.chains are divided into two external domains (.alpha..sub.1 and .alpha..sub.2 or .beta..sub.1 and .beta..sub.2), transmembrane domains 3 and 4 in FIG. 2, and cytoplasmic domains 5 and 6. Cysteine residues that participate in disulfide bridge formation are indicated by S in FIG. 2.
The class I and class II MHC gene products may be glycosylated.
3. Altered Class I and Class II MHC Determinants of the Invention
This invention involves altered determinants corresponding to products of class I and class II MHC loci. This invention also involves an altered MHC class I or class II determinant with an antigen to form a composition that can be recognized by the immune system of a mammal to initiate an immune or cytolytic response.
An altered class I MHC determinant substantially free of associated antigen is diagrammatically depicted in FIG. 3A in which the .alpha..sub.3 domain of the heavy chain is linked to the .beta..sub.2 -microglobulin domain by means of a spacer (shown as a broken line in the Figure). The resulting product, which is depicted in block diagram form in FIG. 3B, is the altered class I MHC determinant of this invention and comprises the .alpha..sub.1, .alpha..sub.2, .alpha..sub.3, and .beta..sub.2 -microglobulin domains covalently linked in sequence. As shown in FIG. 3A, the .alpha..sub.3 domain of the heavy chain is free of the region proximate the transmembrane domain region 1 in FIG. 1 to the carboxyl terminus of the cytoplasmic segment 2.
The altered class I MHC determinant can be prepared by appropriate selection of the MHC locus encoding the .alpha..sub.1, .alpha..sub.2, .alpha..sub.3 domains, and a gene encoding the .beta..sub.2 -microglobulin domain so that each of these domains will retain their functions in activating cytotoxic T cells and in antigen presentation to mammalian T cell receptors. Expression of the polypeptide coded by the MHC locus can be achtechniques dombinant DNA techniques described in detail hereinafter.
An altered class II MHC determinant of the invention is shown in diagrammatic form in FIG. 4A. Referring to the Figure, the amino terminus of the .alpha..sub.1 domain is joined to the carboxyl terminus of the .beta..sub.1 domain, such as by means of a spacer (broken line). Similarly, the carboxyl terminus of the .alpha..sub.2 domain is joined to the amino terminus of the .beta..sub.2 domain, such as by means of another spacer (broken line). The resulting product is the altered class II MHC determinant of this invention, which can be represented by the block diagram shown in FIG. 4B. The altered determinant comprises the .beta..sub.2, .alpha..sub.2, .alpha..sub.1, and .beta..sub.1 domains covalently linked in sequence. As shown in FIG. 4A, the altered determinant is free of the regions proximate the transmembrane domains 3 and 4 in FIG. 2 extending to the carboxyl termini of the cytoplasmic segments 5 and 6, which are normally affixed to the .alpha..sub.1 -.alpha..sub.2 chain and the .beta..sub.1 -.beta..sub.2 chain, respectively. Once again, the portions of the MHC loci are selected to preserve the function of the domains in stimulating a cytotoxic response or in presenting antigen to mammalian T cell receptors.
4. Polypeptides Encoded by MHC
The altered major histocompatibility complex determinant of the invention is a polypeptide encoded by the genetic loci of class I or class II mammalian MHC and .beta..sub.2 m genes, where the polypeptide contains a binding site for an antigen that may be associated with the polypeptide, and when associated, the polypeptide and the antigen together are recognizable by a mammalian T cell receptor. In the case of human class I determinants, the determinant can be a polypeptide encoded by any of genetic loci identified in Table 2, as well as genetic loci not listed and/or not yet discovered.

It will be understood that the present invention is intended to encompass the altered MHC class I and class II determinants of the invention in the form in which they are prepared in situ or in purified form. In addition, the invention encompasses the altered determinants whether or not fully glycosylated and whether obtained using the techniques described herein or other methods. In a preferred embodiment of this invention, the altered MHC class I and class II determinants are totally free or substantially free of one or more of the following components: mammalian tissue and mammalian tissue components, nucleic acids, extraneous proteins and lipids, and adventitious microorganisms, such as bacteria and viruses. It will also be understood that the invention encompasses equivalent determinants having substantially the same biological and immunogenic properties. Thus, this invention is intended to cover variants of MHC determinants.
Depending upon the use to be made of the altered MHC class I and class II determinants, it may be desirable to label them. Examples of suitable labels are radioactive labels, enzymatic labels, fluorescent labels, chemiluminescent labels, and chromophores. The methods for labeling the altered determinants of the invention do not differ in essence from those widely used for labeling immunoglobulin. The need to label may be avoided using labeled antibody to the altered determinants or anti-immunoglobulin to the antibodies to the altered determinants as an indirect marker.
5. Joining the Polypeptide Domains of the Altered MHC Determinant
The domains of the altered MHC determinants correspond to domains encoded by naturally occurring MHC loci and variants thereof that encode MHC products capable of effecting a cytotoxic response by appropriate T cells or inducing an immune response by the lymphocyte. The altered MHC class I and class II determinants of the invention differ from naturally occurring mammalian MHC gene products in that domains of the gene products are covalently linked, such as by means of a spacer. For example, in class I MHC gene products in nature, the class I heavy chain is always non-covalently associated with .beta..sub.2 -microglobulin. In contrast, the altered class I determinant of the invention comprises the class I heavy chain covalently linked to the .beta..sub.2 m domain. Similarly, the altered MHC class II determinant of the invention is comprised of a polypeptide chain in which the .beta..sub.2 -.alpha..sub.2 -.alpha..sub.1 -.beta..sub.1 domains are covalently linked. These domains are never linked in this way in nature. The altered MHC class I and class II determinants are the same as the corresponding MHC gene products in nature in other respects.
The altered MHC determinants of the invention can be obtained from DNA constructs encoding the MHC domains such that there is readthrough translation. For example, in the case of class I MHC determinants, the DNA construct contains a DNA sequence encoding the .alpha..sub.1, .alpha..sub.2, and .alpha..sub.3 domains linked to a DNA sequence encoding the .beta..sub.2 m domain so that there is readthrough translation from the 5' end of the DNA encoding the .alpha..sub.1 domain to the 3' end of the DNA sequence encoding the .beta..sub.2 m domain. Similarly, the altered class II MHC determinants of the invention can be obtained from DNA constructs in which there can be readthrough translation of a DNA sequence encoding the .beta..sub.2 -.alpha..sub.2 -.beta..sub.1 domains.
It was surprisingly discovered that despite the covalent linkage of the MHC domains, the resulting altered MHC class I and class II determinants of the invention mimic the unaltered MHC class I and class II gene products that occur in nature.
In one embodiment of this invention, the MHC domains are covalently linked by a spacer, which is a nucleotide sequence encoding a polypeptide that functions as a hinge in the altered determinant. The spacer allows efficient folding or refolding of the domains with respect to each other such that the altered determinant has the ability to bind antigen or to stimulate the immune system.
The nucleotide sequence of the spacer and the corresponding amino acid sequence have not been found to be critical to the successful practice of this invention. Similarly, the size of the spacer has not been found to be critical. The spacer will generally be of a size to encode a polypeptide of about 2 to about 30 amino acids, and preferably about 5 to about 15 amino acids. Particularly preferred spacers encode polypeptides having about 10 to about 15 amino acids.
A typical spacer for use in a DNA construct encoding an altered H-2 determinant of the invention comprises all or part of the following nucleotide sequence:
SEQ ID NO:15 5'GATCGGATCCGGAGGCGGTGGATCCGGTGGCGGCGGTTC 3'
SEQ ID NO:16 3'CCTAGGCCTCCGCCACCTAGGCCACCGCCGCCAAGCTAG 5'
As another example, all or part of the following nucleotide sequence can be employed to form a spacer of up to 15 amino acids for an altered HLA-A2 determinant of the invention:
______________________________________SEQ ID NO: 17 5'40 GGT GGC GGT GGA TCA GGC GGT GGT CCA CCG CCA CCT AGT CCG CCA CCA - SEQ ID NO: 18 Gly Gly Gly Gly Ser Gly Gly Gly - GGG TCG GGT GGC GGC GGA TCC 3' CCC AGC CCA CCG CCG CCT AGG - Gly Ser Gly Gly Gly Gly Ser______________________________________
This sequence can be inserted after the nucleotides encoding amino acid 274 of HLA-A2 and before the nucleotides encoding amino acid 1 of human .beta..sub.2 -microglobulin resulting in the construction depicted in block diagram form in FIG. 3B.
It will be understood that this invention contemplates the use of the altered MHC determinants in non-cross-linked or cross-linked form. It will also be understood that the altered MHC determinant can be loaded with antigen without unfolding the antigen binding domain. Nevertheless, the invention contemplates unfolding the domain, for example in 7M urea, and dialysis.
6. Antigens Presented in Association with the Altered MHC Determinant
T cells can recognize synthetic peptides loaded on MHC class I and class II molecules. This phenomenon is called MHC restriction. The altered MHC class I determinants and class II determinants of this invention are capable of MHC restriction by association with antigens that are recognizable by T cell receptors of mammalian cells. Crystallography of human MHC class I molecules, HLA-A2 and Aw68, revealed a groove made up by the .alpha..sub.1 and .alpha..sub.2 domains of heavy chains. This groove is believed to be the binding site for antigens. The altered MHC class I determinants of the invention include a binding site of this type for antigens.
More particularly, this invention makes it possible to present antigens to the mammalian immune system and to elicit an immune response in vivo or in vitro. The antigen presented in association with the altered MHC determinant of this invention is generally a peptide. The antigens recognized by MHC class I and class II restricted T cells can be mimicked by artificial peptides. The peptide can also be a naturally occurring peptide. Thus, the peptide can be isolated from a source in which it occurs in nature or the peptide can be chemically synthesized.
When the antigen associated with the altered MHC determinant of this invention is a peptide, the peptide will typically contain about 5 to about 20 amino acid residues, preferably 8, 9 or 10 amino acid residues, when altered class I MHC molecules are used. Longer peptides can be employed with the altered MHC class II determinants of the invention. Octamers, nonomers, and decamers are particularly preferred peptides.
The naturally occurring peptides that normally bind to MHC gene products can be modified at one or more positions by other amino acids. In this event, it will be understood that the modified peptide will not necessarily have the same binding characteristics as the native or unmodified peptide; that is, a distinct allele-specific peptide motif capable of being presented by each MHC determinant may be observed. In any event, the peptide motifs typically contain two anchor positions occupied by a fixed amino acid residue or by one of a few residues with closely related side chains. These anchor positions are not in the same place in the different motifs. In general, the structure of the peptide should match the peptide-binding cleft of the altered MHC determinant. Thus, the allele-specific pockets in the altered MHC determinants of this invention and the side chains of the allele-specific anchor residues should preferably have complementary structures. Following are guidelines for selecting peptide/MHC combinations.
The physical association of antigenic peptides and altered MHC class I and class II determinants of the invention can be monitored using a direct peptide binding assay (PBA) in solid phase or an inhibition peptide binding assay (IPBA) in which the competing peptide is present in a soluble phase. Other tests measuring changes in fluorescence of an appropriately labeled peptide in soluble form when binding to a soluble MHC, or altered MHC molecule, are also available. The ability of different peptides to inhibit the lytic activity of human antiviral cytolytic T cells toward cells incubated with the corresponding target peptide can also be examined as a measure of the effectiveness of antigen binding and presentation.
In general: (a) Binding of a given human T cell-recognized peptide to several HLA class I and class II molecules occurs occasionally. Nevertheless, preferential binding of peptides to their respective restriction molecules is also observed. (b) Binding of HLA molecules to peptides recognized by murine T cells occurs less frequently, but such mechanisms are contemplated by this invention. (c) There exist HIV-1 peptides containing agretopic residues which allow their binding to HLA molecules and are particularly interesting in the scope of the invention. (d) The kinetics of HLA/peptide association depend on the peptide tested and are faster than or similar to those for Ia molecules. (e) Peptide/HLA molecule binding is frequently dependent on length, number of positive charges, and presence of hydrophobic residues in the peptide. (f) A correlation may be observed between a peptide inhibitory effect in the IPBA and its blocking effect in the cytolytic test.
Examples of typical peptides that can be combined with the altered MHC determinants of this invention are given in Table 6.

The antigens described in Tables 6 and 7 are merely representative of antigens that can be presented to cell receptors in association with the altered MHC determinants of this invention. Other antigens that form complexes with the determinants can also be employed. Using both the direct peptide binding assay (PBA) and the inhibition of peptide binding assay (IPBA), the physical interactions between HLA molecules and peptides can be analyzed. More particularly, the assays can be carried out as follows.
Direct Peptide Binding Assay
Wells of microtiter plates are pretreated with 100 .mu.l 2.5% glutaraldehyde in distilled water for 2 h at 20.degree. C., washed with distilled water, and coated for 16 h at 4.degree. C. with 100 .mu.l of peptide diluted at 5.mu.g/ml either in carbonate-bicarbonate buffer, pH 9.6, or in PBS, pH 7.4 or pH 5.0. Remaining free sites are blocked by incubation for 2 h at 20.degree. C. with BSA diluted 1% in PBS containing 0.05% Tween 20 (Tw) and 0.02% sodium azoture. After washing, purified .sup.125 I-HLA molecules (100 .mu.l containing 1.5.times.10.sup.5 cpm, 10.sup.-9 M) diluted in PBS containing 1% BSA, 0.05% Tw, 0.02% sodium azoture, 1 mM PMSF, and 10 .mu.g/ml trypsin inhibitor are added and incubated for 20 h at 20.degree. C. After extensive washing, the radioactivity of each well is counted.
Inhibition Peptide Binding Assay
Concentrations of 0.1-100 .mu.M of competitor peptides are incubated in tubes for 0-3 h at 20.degree. C. with .sup.125 I-HLA (10.sup.-9 M) diluted in PBS-BSA-Tw containing the protease inhibitors as mentioned above. Then the mixture is added to microtiter plate wells coated with a peptide that shows significant binding to HLA molecules in the direct test and incubated 20 h at 20.degree. C. After extensive washing, the radioactivity in each well is counted and the percent of inhibition is calculated.
Competition between Peptides in a Lytic Assay
Human antipeptide CTL is generated (37). Briefly, 6-8.times.10.sup.7 PBMC are stimulated with 100 .mu.g of a synthetic peptide in 10 ml culture medium (RPMI 1640 supplemented with 100 .mu.g/ml penicillin, 100 .mu.g/ml streptomycin, 2 mM L-glutamine, 2 mM nonessential amino acids, 1 mM sodium pyruvate, 10 mM Hepes, and 10% pooled heat-inactivated human AB serum). After a 7-d incubation, a secondary in vitro stimulation is performed by mixing 5-7.times.10.sup.6 effector cells with 2-3.times.10.sup.7 irradiated (4,000 rad) autologous PBMC in 10 ml culture medium containing 50-100 .mu.g of peptide.
In most cases, T cell epitopes are recognized in association with only a few, if not a single, MHC restriction elements. In contrast, some peptides can be recognized in association with several H-2 or HLA molecules. Furthermore, a single peptide can be recognized by both MHC class I and class II restricted T cells. Since class I and class II molecules have a similar predicted tertiary structure, including a single antigen binding site, interactions between peptides and these two types of molecules are also contemplated by this invention. Moreover, it will be understood that this invention contemplates the binding of antigens normally associated with the MHC of one species, such as H-2, to the altered MHC determinant of another species, such as HLA.
The formation of compositions comprising antigens bound to the altered MHC determinants of the invention can be based on peptides known to be antigenically involved in diseases such as AIDS (gag, nef, vif, ret, vpr, or env proteins or peptides), multiple sclerosis (myelin basic protein), toxic shock (bacteria), or snake venom (antigenic region for particular snake venom, alkaloid based and proteinaceous based; current snake bite therapy is based on administration of antibodies to the particular venom). These compositions can be formulated so as to allow the target recognition potential of an immune system cell to be specifically redirected to the antigen in presentation with the altered MHC determinant. It will be understood that libraries comprised of different altered MHC determinants of the invention and associated antigens can be prepared. It is thus possible to formulate compositions comprising two or more of the members of the library in any combination or amount, such as for simultaneously or sequentially targeting different receptors.
The extent of loading of the altered MHC determinant with peptide varies. The altered MHC determinant is typically employed in an amount of about 10 to about 1000 .mu.g/ml and the peptide is employed in an amount of about 10 to about 1000 .mu.g/ml.
While this invention has been described with reference to the use of peptides for binding altered MHC determinants, it will be understood that other antigenic materials can be employed. For example, peptides combined with haptens in general can be employed. Peptides can be combined with metals, such as nickel. Peptides can also be combined with carbohydrates. Certain chemicals, such as p-benzoyl arsonate, also bind directly in the groove of MHC materials. Suitable antigens are reviewed by P. Kourilsky and J. M. Claverie in "Advances in Immunology" (1989).
Similarly, the altered MHC determinants of the invention can be loaded with conventional immunotoxins and directed to a T cell associated with autoimmune disease for the purpose of disabling the T cell. Diptheria toxin, or subunits thereof, and Pseudomonas A toxin are examples of suitable immunotoxins.
7. Binding to Lymphocyte Cell Receptors
The altered MHC class I and class II determinants of the invention and compositions comprising antigens bound to the altered determinants are recognizable by receptors on T lymphocytes.
More particularly, the antigen and MHC recognition structure of T cells is referred to herein as the T cell receptor. The T cell receptor involved in antigen and MHC recognition is characterized in Table 8. Variable regions of the .alpha.- and .beta.-chains form the antigen binding site and also determine MHC specificity. In the presence of antigen and MHC, the T cell is activated. This results in phosphorylation of at least two subunits of the receptor complex, the .delta.- and .epsilon.-chains.

Two other chains on the T cell surface, T.sub.4 (CD4) and T.sub.8 (CD8), are associated with the recognition of the altered class I or class II MHC determinants of the invention, without interacting with antigen. These molecules may normally bind non polymorphic (constant) determinants on class I or class II gene products of the antigen presenting cell. These molecules may also be associated with the T cell receptor.
A summary of the relationship between MHC class I and class II molecules and the type of immune reactive T cells is given in Table 9.
TABLE 9______________________________________Restrictions On Lymphoid Cell Activation Function Phenotype Restriction______________________________________T helper CD4.sup.+ CD8.sup.- Class II MHC + Antigen DTH CD4.sup.+ CD8.sup.- Class II MHC + Antigen CTL CD4.sup.- CD8.sup.+ or Class I or II MHC + CD4.sup.+ CD8.sup.- Antigen Suppressor CD4.sup.- CD8.sup.+ Class I MHC______________________________________
T helper cell activation and delayed hypersensitivity effector (DTH) cells are antigen and class II MHC restricted; CTL activities are antigen and class I or class II MHC restricted. Suppression can be class I restricted or unrestricted. Surface phenotype (CD4 or CD8) correlates mainly with MHC recognition of class II (CD4.sup.+) or class I (CD8.sup.+).
Considering the important regulatory role of class II restricted inducer cells (all of which are CD4 .sup.+), it is not surprising that a virus such as the AIDS-related virus, which infects T cells through the CD4 marker and thus selectively depletes the CD4 population, can cause the severe immune suppression and other abnormalities of lymphocyte growth seen in AIDS patients. This invention should make it possible to inhibit infection of cells by blocking the susceptible cell surface marker with either the altered MHC class I or class II determinant or by the composition comprising antigen bound to the altered determinant. This invention should also make it possible to mimic antigen binding to the T cell receptor .alpha.- and .beta.-chains or to the .delta.-chains. By cross-linking receptors with the altered determinant of the invention, T cell activation is facilitated. This invention thus makes it possible to stimulate or enhance the function of the immune system.
8. Methods of Preparing Altered MHC Class I And Class II Determinants
The altered MHC class I and class II determinants of the invention can be prepared according to well known recombinant DNA techniques. More particularly, nucleic acid sequences encoding the domains of class I and class II MHC gene products and .beta..sub.2 m, and spacers where appropriate, are employed in this invention. A nucleic acid fragment of interest can be ligated to a cloning vehicle. The nucleic acid can be obtained from any source, for example, from plasmids, from cloned DNA or RNA, or from natural DNA or RNA from any source. DNA or RNA can be extracted from a biological material, such as biological fluids or tissue, by a variety of techniques including those described by Maniatis et al., Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory, N.Y. (1982). The nucleic acid will generally be obtained from a higher organism, such as an animal. The nucleic acid sequence can also be chemically synthesized using conventional techniques.
It is not necessary that the nucleic acid fragment to be ligated be present in a pure form. The nucleic acid to be ligated can contain more than one specific nucleic acid sequence, which can be the same or different. The specific nucleic acid fragment to be ligated can be a fraction of a larger molecule or the fragment can constitute an entire gene or assembly of genes encoding the domains of interest. The DNA can be a single-stranded or double-stranded form. If the fragment is in single-stranded form, it can be converted to double-stranded form using DNA polymerase according to conventional techniques.
The nucleic acid fragment to be ligated can have cohesive ends compatible with any combination of sites in a cloning vehicle. Alternatively, the nucleic acid fragment can have one or more blunt ends that can be ligated to corresponding blunt ends in the cloning sites of the vehicle. The nucleic acid fragment to be ligated can be further processed, if desired, by successive exonuclease deletion, such as with the enzyme Bal 31. In the event that the nucleic acid fragment to be ligated does not contain a desired combination of cohesive ends, the fragment can be modified by adding a linker, an adaptor, or homopolymer tailing.
If it is difficult to determine which fragment in a complicated mixture of nucleic acid sequences is desired for ligation, or if it is desired to ligate more than a single nucleic acid fragment, mixtures of nucleic acid fragments can be employed. This procedure can be utilized to generate a small library of clones that contain all compatible fragments in the original nucleic acid mixture.
The cloning vehicle employed in practicing the invention can be any double-stranded DNA molecule capable of transporting the nucleic acid fragment to be ligated into the host cell and capable of replicating within the cell. More particularly, the cloning vehicle must contain at least one DNA sequence that can act as the origin of replication in a host cell. In addition, the cloning vehicle must contain two or more sites for insertion of the nucleic acid sequence to be ligated. These sites will ordinarily correspond to restriction enzyme sites at which cohesive ends can be formed, and which are complementary to the cohesive ends on the nucleic acid fragment to be ligated to the vehicle. In general, this invention can be carried out with plasmid, bacteriophage, or cosmid cloning vehicles having these characteristics.
It is preferred that the plasmid carry one or more genes responsible for a useful characteristic, such as selectable marker, displayed by the host cell. In one type of strategy, plasmids having genes for resistance to two different drugs are chosen. For example, insertion of the DNA fragment of interest into a gene for an antibiotic inactivates the gene and destroys drug resistance. The second drug resistance gene is not affected when bacterial cells are transformed with the recombinants, and colonies containing the gene of interest can be selected by resistance to the second drug and susceptibility to the first drug. Preferred antibiotic markers are genes imparting chloramphenicol, ampicillin, or tetracycline resistance to the host cell.
When a plasmid is employed, the plasmid can be derived from bacteria or some other organism or the plasmid can be synthetically prepared. The plasmid can replicate independently of the host cell chromosome or an integrative plasmid (episome) can be employed. The plasmid can make use of the DNA replicative enzymes of the host cell in order to replicate or the plasmid can carry genes that code for the enzymes required for plasmid replication. A number of dif- ferent plasmids can be employed in practicing this invention. Typical of the plasmids that can be utilized are pBR322, pBR325, Co1E1, RP4, and the 2 .mu.m circle that occurs in many strains of the yeast Saccharomyces cerevisiae. The cloning vehicle can also be a bacteriophage. It will be understood that this invention can be practiced with phage vectors that proliferate by a lytic cycle or by lysogenic infection.
Cloning can be carried in procaryotic or eucaryotic cells. The host for replicating the cloning vehicle will of course be one that is compatible with the vehicle and in which the vehicle can replicate. Cloning can be carried out in bacterial or yeast cells, although cells of fungal, animal, and plant origin can also be employed. The preferred host cells for conducting cloning work are bacterial cells, such as E. coli, as well as species of Streptomyces, Bacillus, and Pseudomonas. The use of E. coli cells is particularly preferred because most cloning vehicles, such as bacterial plasmids and bacteriophages, replicate in these cells. Yeast cells can also be employed for cloning work. Also preferred are strains of Saccharomyces cerevisiae. Animal cells, such as COS monkey cells, are preferred where post-translational processing of the altered MHC determinant is desired. For example, the altered MHC class I and class II determinants of the invention can be prepared in glycosylated form in COS cells. This invention thus contemplates the preparation and use of the altered determinants of the invention in glycosylated or non-glycosylated form.
Expression control sequences can be included in the vector of this invention. These include the operator, promoter and ribosome binding and interaction sequences (including sequences such as the Shine-Dalgarno sequences), the lactose operon of E. coli ("the lac system"), the corresponding sequences of the tryptophan synthetase system of E. coli ("the trp system"), the major operator and promoter regions of phage .lambda.(O.sub.L P.sub.L and O.sub.R P.sub.R.sup.I), and the control region of the phage fd coat protein. DNA fragments containing these sequences can be excised by cleavage with restriction enzymes from the DNA isolated from transducing phages that carry the lac or trp operons, or from the DNA of phage .lambda. or fd. These fragments can then be manipulated in order to obtain a limited population of molecules such that the essential controlling sequences can be joined very close to, or in juxtaposition with, the initiation codon of the coding sequence for the desired gene product. The product is then inserted into a cloning vehicle for transformation of the appropriate hosts and the level of production measured. Cells giving the most efficient expression can be selected.
To shorten the distance between the particular expression control sequence and the initiation codon of the chosen gene fragment, the particular fragment may be treated lightly with a combination of nucleases acting specifically at or near its terminus or used in exonuclease and polymerase-linked repair reactions to remove some or all of those nucleotides of the fragment preceding the fragment's start codon. Alternatively, a fragment can be similarly shortened with exonuclease treatment or polymerase-linked repair reactions and then cleaved to produce one fragment to permit fusion to another fragment before attachment to the expression control sequence.
The nucleotide sequences encoding domains of class I and class II mammalian gene products are known in the art and can be employed in practicing this invention. For example, following are primary structural data for .beta..sub.2 m molecules from several different species that can be employed in practicing this invention.

Genes encoding other MHC gene products can be determined from the physical map of the MHC gene complex for the mammalian species of interest.
9. Antibodies to Altered Determinants and Compositions of The Invention
The altered MHC class I and class II determinants of the invention and compositions containing antigens bound to the determinants are useful for the preparation of antibodies that recognize these substances. The antibodies have diagnostic uses, application in mammalian therapy, and use in the study of MHC and cellular processes.
More particularly, polyclonal or monoclonal antibodies can be used in a variety of applications. Among these the neutralization of MHC gene products by binding to the gene products on cell surfaces. They can also be used to detect MHC gene products in biological preparations or in purifying corresponding MHC gene products or the altered MHC class I and class II determinants of the invention, such as by affinity chromatography.
Antibodies according to the present invention can be prepared by any of a variety of methods. For example, cells expressing an altered determinant or a functional derivative thereof can be administered to an animal in order to induce the production of sera containing polyclonal antibodies that are capable of binding the altered determinant. In addition, antibodies can be prepared to a variety of altered MHC class I and class II determinants of the invention and compositions containing antigens bound to the determinants in a similar manner.
In a preferred method, the antibodies are monoclonal antibodies, which can be prepared using hybridoma technology (Kohler et al., Nature 256:495 (1975); Kohler et al., Eur. J. Immunol. 6:511 (1976); Kohler et al., Eur. J. Immunol. 6:292 (1976); Hammerling et al., In: Monoclonal Antibodies and T-Cell Hybridomas, Elsevier, N.Y., pp. 563-681 (1981)). In general, such procedures involve immunizing an animal with the altered MHC determinant or the altered MHC-antigen composition. Splenocytes of the animals are extracted and fused with a myeloma cell line. After fusion, the resulting hybridoma cells can be selectively maintained in HAT medium, and then cloned by limiting dilution as described by Wands, J. R., et al. Gastroenterology 80:225-232 (1981). The hybridoma cells obtained are then assayed to identify clones secreting antibodies capable of binding the altered MHC determinant or the composition.

The antibodies can be detectably labeled. Examples of labels that can be employed in the present invention include, but are not limited to, enzymes, radioisotypes, fluorescent compounds, chemiluminescent compounds, bioluminescent compounds and metal chelates.
Examples of enzymes include malate dehydrogenase, staphylococcal nuclease, delta-V-steroid isomerase, yeast alcohol dehydrogenase, alpha-glycerophosphate dehydrogenase, triose phosphate isomerase, biotin-avidin peroxidase, horseradish peroxidase, alkaline phosphatase, asparaginase, glucose oxidase, .beta.-galactosidase, ribonuclease, urease, catalase, glucose-VI-phosphate dehydrogenase, glucoamylase and acetylcholine esterase.
Examples of isotopes are .sup.3 H, .sup.125 I, .sup.32 P, .sup.35 S, .sup.14 C, .sup.51 Cr, .sup.36 Cl, .sup.57 Co, .sup.58 Co, .sup.59 Fe, and .sup.75 Se. Among the most commonly used fluorescent labeling compounds are fluoroscein, isothiocyanate, rhodamine, phycoerythrin, phycocyanin, allophycocyanin, o-phthaldehyde and fluorescamine.
Examples of typical chemiluminescent labeling compounds are luminal, isoluminol, theromatic acridinium ester, imidazole, acridinium salts, oxalate ester, and dioxetane.
Those of ordinary skill in the art will know of other suitable labels for binding to antibodies, or will be able to ascertain the same by the use of routine experimentation. Furthermore, the binding of these labels to antibodies can be accomplished using standard techniques commonly known to those of ordinary skill in the art. Bioluminescent compounds for purposes of labeling include luciferin, luciferase and aequorin.
The antibodies and antigen of the present invention are ideally suited for the preparation of a kit. Such kit may comprise a carrier means being compartmentalized to receive one or more container means, such as vials, tubes and the like, each of said container means comprising the separate elements of the assay to be used.
10. Diagnostic Applications
The altered MHC class I and class II determinants, compositions containing antigens bound to the altered determinants, and antibodies to these substances are useful in diagnostic applications. For example, the altered determinants can be used to target lymphocyte receptors, such as CD4.sup.+ and CD8.sup.+ receptors of T lymphocytes, and the resulting bound determinant can be assayed, for instance, by means of an antibody to the bound determinant. In addition, it will be understood that the altered MHC determinants of the invention can be labeled in the manner previously described for antibodies. In this case, the label on the altered MHC determinant can be detected and quantified. Compositions comprising an antigen bound to an altered determinant of the invention can be used in a similar manner with MHC-restricted receptors recognizing the antigen and the determinant.
Typical examples of assays based on the antibodies of the invention are radioimmunoassays (RIA), enzyme immunoassays (EIA), enzyme-linked immunosorbent assays (ELISA), and immunometric or sandwich immunoassays, including simultaneous sandwich, forward sandwich, and reverse sandwich immunoassays.
In the preferred mode for performing the assays it is desirable to employ blockers in the incubation medium to assure that non-specific proteins, protease, or human antibodies to immunoglobulins present in the experimental sample do not cross-link or destroy the antibodies and yield false positive or false negative results. Nonrelevant (i.e. nonspecific) antibodies of the same class or subclass (isotype) as those used in the assays (e.g. IgG, IyM, etc.) can be used as blockers. In addition, a buffer system should be employed. Prefbe employed. Preferred buffers are those based on weak organic acids, such as imidazole, HEPPS, MOPS, TES, ADA, ACES, HEPES, PIPES, TRIS, and the like, at physiological pH ranges. Somewhat less preferred buffers are inorganic buffers such as phosphate, borate or carbonate. Finally, known protease inhibitors can be added to the buffer.
Well known solid phase immunoadsorbents, such as glass, polystyrene, polypropylene, dextran, nylon and other materi- als, in the form of tubes, beads, and microtiter plates formed from or coated with such materials, can be employed in the present invention. Immobilized antibodies can be either covalently or physically bound to the solid phase immunoadsorbent by techniques, such as covalent bonding via an amide or ester linkage, or by adsorption.
11. Immunization and Therapeutic Administration
In another embodiment of this invention, the altered MHC class I and class II determinants and compositions containing antigens bound to the determinants and antibodies to these substances can be administered to a mammal to produce a therapeutic effect. For example, immune responses to self components represent a failure of immunological tolerance. As a result, clones of T cells and B cells emerge bearing receptors for self-antigens, which can lead to the production of self-directed antibodies, cytotoxic T cells, and inflammatory T cells. Such a breakdown in tolerance produces an autoimmune response that can cause autoimmune diseases. Administration of the altered determinants, compositions, or antibodies of the invention can intervene in these processes. Thus, for example, this invention can be utilized to treat T cell mediated autoimmune diseases, such as thyroiditis and multiple sclerosis.
This invention also provides altered MHC class I and class II determinants for use in therapeutic or vaccine compositions. Conventional modes of administration can be employed. For example, administration can be carried out by oral, respiratory, or parenteral routes. Intradermal, subcutaneous, and intramuscular routes of administration are preferred when the vaccine is administered parenterally.
The ability of the altered determinants and compositions of the invention to exhibit a therapeutic or immunizing effect can be enhanced by emulsification with an adjuvant, incorporation in a liposome, coupling to a suitable carrier, or even in cells, or by combinations of these techniques. For example, the altered determinants and compositions can be administered with a conventional adjuvant, such as aluminum phosphate and aluminum hydroxide gel, in an amount sufficient to mediate humoral or cellular immune response in the host. Similarly, these reagents can be bound to lipid membranes or incorporated in lipid membranes to form liposomes. The use of nonpyrogenic lipids free of nucleic acids and other extraneous matter can be employed for this purpose.
In addition, any of the common liquid or solid vehicles can be employed, which are acceptable to the host and do not have any adverse side effects on the host nor any detrimental effects on the reagents of the invention. Conveniently, phosphate buffered saline at a physiological pH can be employed as the carrier. One or more injections may be required, particularly one or two additional booster injections. It will be understood that conventional adjuvants, such as SAF-1, complete Freund's adjuvant and incomplete Freund's adjuvant, or oil-based adjuvants, such as mineral oil, can be administered with the reagents of the invention to elicit an increased antibody or cell-mediated immune response.
The immunization schedule will depend upon several factors, such as the susceptibility of the host and the age of the host. A single dose of the reagents of the invention can be administered to the host or a primary course of immunization can be followed in which several doses at intervals of time are administered. Subsequent doses used as boosters can be administered as needed following the primary course.
In an initial protocol, the mouse can be injected with about 10 to about 20 .mu.g of the altered MHC determinant of the invention per injection. The usual vaccine dosages can be employed in humans.
In addition to the antibodies produced for kits and diagnostic assays, antibodies of the present invention can be humanized by procedures well known in the art (using either chimeric antibody production or CDR grafting technology). U.S. Pat. No. 4,816,567 Cabilly et al., EPA 0120694 Publication No., assigned to Celltech, EPA 0173494 Publication No. assigned to Stanford University, and EPA 0125023 Publication No. assigned to Genentech, describing chimeric antibody procedures and EPA 0194276 Publication No. assigned to Celltech describing CDR grafting procedures.
The humanized antibodies would be prepared from antibodies obtained against specific MHC-antigen complexes. The humanized antibodies could then be used therapeutically in humans so as to avoid the problems associated with the use of non-human antibodies in human therapy.
This invention will now be described in greater detail in the following Examples.
EXAMPLE I
Engineering of Single-Chain Murine Class I Maior Transplantation Antigen
Single-chain mouse K.sup.d molecules (SC-K.sup.d) were engineered by connecting residue 276 of K.sup.d heavy chain to the first residue of .beta..sub.2 -microglobulin through spacers of various lengths, and expressed intracellularly in monkey COS-1 cells. Labeled SC-K.sup.d molecules were found to react with several monoclonal antibodies, which recognize native K.sup.d molecules. SCK.sup.d -15 (with a spacer of 15 residues) was studied in more detail. It could be purified and shown to regain a native-like structure after treatment with denaturing agents. Purified SC-K.sup.d -15 could bind certain peptides in a manner qualitatively similar to that of K.sup.d.
Plasmid Constructs
A full-length K.sup.d cDNA (Lalanne, J.-L., Delarbre, C., Gachelin, G., and Kourilsky, P., Nucleic Acids Res., 1983. 11:1567) was cut by Hind III (at the level of residue 276) and fused in phase, by a Gly-Gly coding linker, to .beta..sub.2 m cDNA (Daniel, F., Morello, D., LeBail, O., Chambon, P., Cayre, Y., and Kourilsky, P., EMBO J. 1983. 2:1061) in which a Bam HI site overlapping the first Ile codon of mature .beta..sub.2 m had been introduced by site-directed mutagenesis. The block was cloned in a mammalian expression vector, pKC3 (kindly provided by Dr. Hanahan, U.C.S.F.), which contains the SV40 promoter and origin of replication, yielding pSC-K.sup.d -2 (shown in Gene Constructs discussion, FIG. 5A). Synthetic linkers of different lengths were then ligated at the Bam HI site of pSC-K.sup.d -2 (FIG. 5B). For example, the SC-K.sup.d -15 liner was:
SEQ ID NO:15 5'GATCGGATCCGGAGGCGGTGGATCCGGTGGCGGCGGTTC 3'
SEQ ID NO:16 3'CCTAGGCCTCCGCCACCTAGGCCACCGCCGCCAAGCTAG 5'
Bam HI digestion of pSC-K.sup.d -15 and religation yielded pSC-K.sup.d -10. PSC-K.sup.d -13, -17, -19 and -21 were obtained by cloning the appropriate linkers into the Bam HI site of pSC-K.sup.d -10. All spacers and junctions were sequenced.
Transfection and immunoprecipitation
COS-1 cells (about 3.5.times.10.sup.6 cells in 60-mm plates) grown in DMEM supplemented with 10% newborn serum, penicillin, streptomycin and L-glutamine, were transfected one day after plating with 0.5 ml calcium phosphate mixture containing 5 .mu.g of CsCl-purified plasmid DNA. Transfection efficiencies were occasionally monitored with pCH110plasmid expressing E. coli.beta.-galactosidase (Pharmacia, Uppsala, Sweden). Thirty-six hours after transfection, cells were radiolabeled with [.sup.35 S] methionine (45 .mu.Ci/plate =1.67 m Bq/plate) for 4 h at 37.degree. C., then washed once in PBS and collected in 1 ml lysis buffer (10 mM Tris-HCl, pH 7.4 1 mM EDTA, 150 .mu.M NaCl, 1% w/v NP40, BSA 10 mg/ml) containing 20 mM iodoacetamide and 1 IU/ml aprotinin. Lysates were precleared with protein A-Sepharose for 1 h at 4.degree. C., and SN were incubated for 18 h at 4 .degree. C. with either 30 .mu.l of culture SN or 5 .mu.l of purified mAb and protein A-Sepharose. The beads were washed three times and the proteins were eluted in Laemmli buffer with 2-ME and analyzed by SDS-PAGE on 12% gels. Gels were fixed, treated with Amplify (Amersham Int., Amersham, GB), dried and visualized by autoradiography with use of Kodak (Rochester, N.Y.) XAR-X-ray film.
For endoglycosidase H (Endo H) treatments, samples were equilibrated in 0.5% SDS, 1 M 2-ME, boiled for 2 min., precipitated with 15% trichloroacetic, rinsed with acetone and resuspended in 50.mu.l 50 mM sodium citrate, pH 5.5, 0.1% SDS, 20 mM2-ME. Endo H (Boehringer-Mannheim, Mannheim, FRG) was added to a final concentration of 150 mU/ml, samples were incubated at 37.degree. C. for 24 h, and then analyzed by SDS PAGE.
Immunoaffinity Purification of SC-K.sup.d -15 protein
COS-1 cells (usually 10.sup.7 cells) were transfected with pSC-K.sup.d -15 DNA, labeled and lysed as above. SN were precleared with protein A-Sepharose for 1 h at 4.degree. C. then incubated for 18 h at 4.degree. C. with 100 .mu.l mAb 34.1.2 covalently bound to protein A beads. After the final wash in PBS, SC-K.sup.d -15 was eluted from the matrix with an equal volume of 3 M thiocyanate for 10 min on ice. After an overnight dialysis in PBS containing 0.1% NP40, 0.05% Tween and 0.2% BSA, SC-K.sup.d -15 was used in direct binding test as below. Its purity was assessed by SDS-PAGE.
Peptides and Peptide Binding Assays
Peptides used in this study are described in Choppin et al. (Choppin, J., Martinon, F., Gomard, E., Bahraoui, E., Connan, F., Bouillot, F., and Levy, J.-P, J. Exp. Med., 1990. 172:889 and references therein), except for HLA-Cw3 and HLA-A24 described in Maryanski, J. Ll, Pala, P., Cerottini, J.-C, and Corradin, G., J. Exp. Med. 1988. 167:1391. Binding as-says were performed as described in Choppin, J., Martinon, F., Gomard, E., Bahraoui, E., Connan, F., Bouillot, F., and Levy, J.-P, J. Exp. Med., 1990. 172:889. DR3, DRw13, and K.sup.d molecules were also purified and iodinated as in Choppin, J., Martinon, F., Gomard, E., Bahraoui, E., Connan, F., Bouillot, F., and Levy, J.-P, J. Exp. Med., 1990. 172:889.
Gene Constructs
The C-terminal part of the K.sup.d heavy chain truncated in the hinge region was hooked to the N-terminal part of .beta.2-microglobulin with an appropriate spacer. From the 3-D structure of K.sup.d (Prochnicka-Chalufour, A., Casanova, J.-L, Kourilsky, P., and Claverie, J.-M, Res. Immunol., 1989. 140:133) modeled after the HLA-A2 structure of Bjorkmann et al. (Bjorkmann, P. J., Saper, M. A., Samraoui, B., Bennet, W. S., Strominger, J. L., and Wiley, D. C., Nature 1987. 329:506), the minimal length of a polyglycine type of spacer was estimated to be 11 residues, starting from residue 276 in the K.sup.d amino acid sequence (which allows the use of a convenient restriction site in the K.sup.d cDNA).
Two full-length cDNA clones encoding K.sup.d (Lalanne, J.-L, Delarbe, C., Gachelin, G., and Kourilsky, P., Nucleic Acids Res., 1983. 11:1567) and .beta..sub.2 -microglobulin (Daniel, F., Morello, D., LeBail, O., Chambon, P., Cayre, Y. and Kourilsky, P., EMBO J. 1983. 2:106) were connected by synthetic oligonucleotides encoding the spacers. The latter were designed as repeats of several glycines and one serine, (see discussion Plasmid Constructs). A series of pSC-K.sup.d -coding of cDNA with spacers of 2, 10, 13, 15, 17, 19 and 21 amino acid residues were thus obtained. The verified sequences are shown in FIG. 6.
Expression of SC-Kd in Transfected Monkey COS-1 Cells
COS-1 cells (in which the recombinant plasmids replicate) were transiently transfected for 36 h and labeled with [.sup.35S ] methionine for 4 h. SC-K.sup.d molecules were not directly detectable by electrophoresis of SN or cell extracts. For immunoprecipitation, mAb 34-1-2 (Ozato, L., Mayer, N. and Sachs, D. H., Transplantation, 1982. 34:113), which reacts with native K.sup.d and D.sup.d.
SN contained 20-50 fold less immunoprecipitable material than cellular extracts. This is not unexpected because the K.sup.d heavy chain truncated at the level of the Hind III site is not secreted by COS-1 cells (Chambon, P., D.E.A.. thesis, University of Paris, 1987). In cellular extracts, bands corresponding to proteins with an apparent molecular mass of about 52 kDa were specifically precipitated, and their mobility decreased slightly as the length of the spacer increased (FIG. 6A, SC-K.sup.d -2,-10, -13, -17, -19, -21; for SC-K.sup.d -15, see FIG. 6B). No band was seen with mock-transfected cells and 34-1-2 (FIG. 8A, lanes NT and pKC), nor with transfected cells and an irrelevant antibody (F23, 1; FIG. 6B). After the results of Townsend et al. (Townsend, A., Ohlen, C., Bastin, J., Ljunggren, H.-G., Foster, L., and Karre, K., Nature 1989. 340: 443) with the RMA-S mutant cell line, whether the addition of large amounts of an immunogenic peptide. (influenza NPR.sup.31 ) was investigated and found to have no effect (FIG. 6A and 6B). In much of the following work, SC-K.sup.d -15 was arbitrarily chosen as the prototype SC-K.sup.d molecule.
In separate studies using baculovirus vectors, it has been verified that 34-1-2 reacts very poorly with the K.sup.d heavy chain expressed in insect cells in the absence of mouse .beta..sub.2 -microglobulin (about 20- to 50-fold fold less than K.sup.d associated to .beta..sub.2 -microglobulin). Reactivity with 34-1-2 is thus a strong indication that K.sup.d heavy chain is properly associated with .beta..sub.2 -microglobulin. To probe other parts of the K.sup.d molecule, other K.sup.d -specific mAb (97-G and 20-8-4 (Ozato, L., Mayer, N. and Sachs, D. H., Transplantation, 1982. 34: 113 and Rebai, N., Mercier, P., Kristensen, T., Devaux, C., Malissen, B., MAwas, C., and Pierres, M., Immunogenetics 1983. 17: 57) were used and identical results were obtained. As an example, the SC-K.sup.d -2 and SC-K.sup.d -15 bands precipitated by mAb 20-8-4 are shown in FIG. 6B. The exact specificity of 97-G is not known, but the epitope recognized by 20-8-4 has been shown to include residues 82 and 89 belonging to the first domain of K.sup.d (Abastado, J.-P., Jaulin, C., Schutze, M.-P., Langlade-Demoyen, P., Plata, F., Ozato, K., and Kourilsky, P., J. Exp. Med. 1987. 166: 327. Thus, this epitope is properly folded in SC-K.sup.d -2 and SC-K.sup.d -15 (as well as in other SC-K.sup.d molecules.
The state of glycosylation of intracellular SC-K.sup.d -15 was assessed by treatment with Endo H. The molecule appears to be fully Endo H sensitive (FIG. 6C) and, after treatment, its apparent molecular mass is about 45 kDa, which fits the expected molecular mass of non-glycosylated SC-K.sup.d -15 devoid of its signal peptide (390 amino acids). These results suggest that most of the SC-K.sup.d -15 molecules are found in the endoplasmic reticulum in a high-mannose form.
With all three mAb, the precipitated SC-K.sup.d -2 band was always 5-10 fold less intense than that obtained with SC-K.sup.d molecules with longer spacers. However, the Gly-Gly spacer is unlikely to allow proper association of .beta..sub.2 -microglobulin to the heavy chain. A 12-kDa band, presumably monkey .beta..sub.2 -microglobulin, is co-precipitated in relatively much higher amounts with SC-K.sup.d -2 than with other SC-K.sup.d (FIG. 6D). This suggests that monkey .beta..sub.2 -microglobulin may associate better with SC-K.sup.d -2 than with other SC-K.sup.d where the longer spacer permits proper folding of the murine .beta..sub.2 -microglobulin over the K.sup.d heavy chain, which could explain the detection of some SC-K.sup.d -2 molecules. In any case, monkey .beta..sub.2 -microglobulin does not play a compulsory role in the folding of SC-K.sup.d -15 since it has been possible to produce immunoprecipitable SC -K.sup.d -15 in insect cells infected by a recombinant baculovirus.
Purification and Peptide Binding
The reactivity of SC-K.sup.d molecules with three distinct mAb provided evidence for their native-like character Nevertheless, it was necessary to purify these molecules, check their ability to fold back after treatments which separate heavy chain from .beta..sub.2 m, and finally test whether they were able to bind peptides.
A solid-phase matrix, made of 34-1-2 coupled to protein A beads, was used to purify .sup.35 S-labeled SC-K.sup.d -15 from lysates of transiently transfected COS-1 cells. Treatment with 3 M sodium thiocyanate eluted the protein with a reasonable yield (about 70%) as assessed by a second immunoprecipitation with 34-1-2. After electrophoresis, the purified material ran as a single 52-kDa band. This confirmed that reactivity with 34-1-2 can be regained in the absence of detectable monkey .beta..sub.2 -microglobulin. This eluting treatment would normally dissociate heavy chain from .beta..sub.2 -microglobulin (Elliott, T., and Eisen, H. N., Proc. Natl. Acad. Sci., USA 1990. 87: 5213). In addition 6 M urea was also used with similar results (not shown).
K.sup.d molecules isolated from the spleen of BALB/c mice were then purified and iodinated. They were purified by affinity chromatography on a 20-8-4 mAb column and compared binding of peptides by the latter and by .sup.35 S-labeled SC-K.sup.d -15 in the assay of Bouillot et al. (Bouillot, M., Choppin, J., Cornille, F., Martinon, F., Papo, T., Gomard, E., Fournie-Zaluski, M.-C., and Levey, J.-P., Nature 1989. 339: 473 and Choppin, J., Martinon, F., Gomard, E., Bahraoui, E., Connan, F., Bouillot, F., and Levy, J.-P, J. Exp. Med., 1990. 172: 889).
Two peptides from HIV viral proteins (env 312-327 and vpr 68-80), known to bind strongly to several MHC molecules (Choppin, J., Martinon, F., Gomard, E., Bahraoui, E., Connan, F., Bouillot, F., and Levy, J.-P, J. Exp. Med., 1990. 172: 889), showed significant binding to SC-K.sup.d -15 as well as to the HLA-DR3 or DR213 positive control (Table 10; results shown in duplicate). In a separate experiment, the binding of SC-K.sup.d -15) and that of conventional Kd were compared (Table 10). As above, peptide env 312-327 was found to bind to both molecules, but three peptides known to be immunogenic (HLA -A24 170-182, HLA-Cw3 170-182 and influenza NPR- 147-158; (Maryanski, J. L., Pala, P., Cerottini, J.-C. and Corradin, G., J. Exp. Med. 1988. 167: 1391 and Bodmer, H. C., Pemberton, R. M., Rothbard, J. B., Askonas, B. A., Cell 1989. 52: 253), showed no detectable binding, either to the SC-K.sup.d nor to the K.sup.d molecules. In a competition experiment in which the env 312-327 peptide is bound to plastic, it was seen that the vpr 68-80 peptide competed efficiently, while the Cw3 170-182 peptide (which did not bind in the direct assay) did not. In summary, SC-K.sup.d -15 bound in the HIV peptides env 312-327 and vpr 68-80 to a significant extent, albeit somewhat less efficiently than conventional K.sup.d (but the optimal conditions may be different for K.sup.d and SC-K.sup.d -15 and efforts have not been made to optimize binding to SC-K.sup.d -15 at this stage).
There was no detectable binding of three immunogenic peptides neither to SC-K.sup.d -15 nor to K.sup.d. It is possible that these peptides bind much less efficiently than the two above-described HIV peptides and that the assay, as carried out here, is not sensitive enough to detect binding. Similar observations have been made before (Choppin, J., Martinon, F., Gomard, E., Bahraoui, E., Connan, F., Bouillot, F., and Levy, J.-P, J. Exp. Med., 1990. 172: 889).
In conclusion, not ignoring the difficulties associated with the interpretation of such peptide binding experiments, this example demonstrates that the behavior of SC-K.sup.d -15 is qualitatively similar to that of conventional K.sup.d. This is clear preliminary evidence that SC-K.sup.d -15 is capable of binding peptides in a manner similar to that of K.sup.d.
In conclusion, this example demonstrates the engineering of single-chain K.sup.d molecules which so far display the expected properties with respect to (a) reactivity with three mAb, one of which probes proper association with .beta..sub.2 -microglobulin and another one an epitope belonging to the first domain, (b) efficient refolding upon treatment with 3 M sodium thiocyanate or 6 M urea, and (c) binding of certain peptides. Above 10 residues or so, the length of the spacer between K.sup.d heavy chain and murine .beta..sub.2 -microglobulin does not seem critical. All experiments described have been performed with trace amounts of metabolically labeled SC-K.sup.d molecules. Production in large amounts should yield material useful for peptide and TcR binding studies.

EXAMPLE II
Preparation of an HLA-.beta.2-Microglobulin (MHC Class I) Peptide Complex
The "empty"(i.e. devoid of peptide) MHC class I molecule is produced in vast amounts in the periplasm of the E. coli strain harboring the recombinant plasmid. Inclusion bodies can be isolated, washed briefly in 6 M urea, and then dissolved in 8 M urea, or 6 M urea+3 M isothiocyanate. The solubilized MHC class I molecules are then mixed with a 100 fold (or more) molar excess of a peptide specifically presented by HLA-A2 or MHC class I, such as Influenza virus or HIV peptides described as optimal nonapeptides by Falk et al. (Nature (1991) 351, 290). The MHC class I peptide mixture in a dialysis bag is then dialyzed in a small volume of 6 M urea plus peptide, then 4 M urea plus peptide, then 2 M urea plus peptide, then large volumes of buffer. The MHC class I peptide complex is then purified by conventional methods (such as those described in "Protein Purification Applications", Harris E. L. V. & Angal S. (Eds.) IRL Press, Oxford, 1990).
EXAMPLE III
Immunization
For immunization, the complex is usually coupled to a protein carrier, as it is done for synthetic vaccines. Usual vaccination protocols (with several immunizations and a recall injection) should be used. The antibody response should be mainly focussed on the peptide presented by the SC -A2 molecule. In a typical experiment, mice will be injected on the base of the tail of 100 .mu.l of complete Freund adjuvant together with 100 .lambda. of the SC-A2 peptide complex itself coupled to a carrier such as ovalbumin of KLM. Immunization is repeated once or twice, in the following weeks. One month later, mice are boosted and the response is tested.
EXAMPLE IV
Identification and Sequencing of T-cell Region Capable of Binding HLA-A2-.beta.2 Microglobulin
The sequences disclosed by the invention in Examples I and II provide for a method of identifying the interaction responsible for the T-cell recognition of HLA-A.sub.2 -.beta..sub.2 -microglobulin (MHCI).
In detail, using the sequences disclosed in Examples I and II, it is possible to isolate the proteins which bind to these sequences. This is accomplished using one of the methods of purifying a protein which binds to a specific DNA sequence. Such procedures are well known in the art. Preferably, a protein which binds to a specific DNA sequence can be purified using affinity chromatography.
Specifically the amino acid sequence corresponding to the HLA-A.sub.2 -.beta..sub.2 -microglobulin binding domain is immobilized on an appropriate matrix, such as Sepharose, and used as an affinity matrix for the purification of the proteins which bind to the particular sequence (Arcangioli B, et al., Eur. J. Biochem. 179: 359-364 (1989).
Preferably the DNA binding protein is extracted from human T-cells. The protein extract, obtained from the T cell is applied to a column which contains the immobilized DNA sequence of interest. Proteins which are not capable of binding to the DNA sequence are washed off the column. Proteins which bind to the DNA sequence are removed from the column using a salt gradient. The proteins eluted from such a column are enriched for the proteins which bind to the specific DNA sequences immobilized on the matrix. The DNA binding protein can then be further purified using procedures known in the art such as ion exchange chromatography, high performance liquid chromatography, and size exclusion chromatography.
During the purification of the DNA binding protein, the protein can be assayed using a gel retardation assay. (Garner, M.M. et al., Nucl. Acid Res. 9: 3047 and Fried, M. et al., Nucl. Acid Res. 9: 6506 (1981).
Once the DNA binding protein has been purified, a partial amino acid sequence can be obtained from the N-terminal of the protein. Alternatively, the protein can be tryptically mapped and the amino acid sequence at one of the fragments can be determined by one of the methods known in the art.
The deduced amino acid sequence can be used to generate an oligonucleotide probe. The encoding sequence can be based on codons which are known to be more frequently used by the organism. Alternatively, the probe can consist of a mixture of all the possible codon combinations which could encode the polypeptide.
A probe complementary to the amino acid sequence can be used to screen either a cDNA or genomic library for the genomic sequences which encode the DNA binding protein. Once the gene encoding the DNA binding protein has been obtained, the sequence of the DNA can be determined, the gene can be used to obtain large amounts of the protein from a recombinant host, or the sequence can be used in mutational analysis to further define the functional regions within the protein which interacts with the DNA.
Alternatively, proteins which bind to T-cell epitope can be isolated by identifying a clone expressing the protein using the technique of Southwestern blotting (Sharp, Z.D. et al., Biochim Biophys Acta, 1048: 306-309 (1990), Gunther, C. V. et al., Genes Dev. 4: 6657-679 (1990), and Walker, M. D. et al., Nucleic Acids Res. 18: 1159-1166 (1990)).
In a Southwestern blot, a labeled DNA sequence is used to screen a cDNA expression library whose expressed proteins have been immobilized on a filter via colony or plaque transfer. The labeled DNA sequences will bind to colonies or plaques which express a protein capable of binding to the particular DNA sequence. Clones expressing a protein which binds to the labeled DNA sequence can be purified and the cDNA insert which encodes the DNA binding protein can be isolated sequenced. The isolated DNA can be used to express large amounts of the protein for further purification and study, used in isolating the genomic sequences corresponding to the cDNA, or used to generate functional derivative of the binding protein.
While this invention has been described in connection with specific embodiments thereof, it will be understood that it is capable of further modifications and this application is intended to cover variations, uses, or adaptations of the invention following, in general, the principles of the invention and including such departures from the present disclosure as come within the art to which the invention pertains and as may be applied to the essential features hereinbefore set forth as follows in the scope of the appended claims.
