WO ~ ,ass PCT~US97/14641 SECRETED PROTEINS AND POLYNUCLEOTIDES ENCODING THEM

This application is a continuation-in-part of application Ser. No. 08/702,420, filed August 14, 1996, entitled "SECRETED PROTEINS AND POLYNUCLEOTIDES
ENCODING THEM", filed in the name of some or all of the inventors of the presentapplication.

FIELD OF THE INVENTION
The present invention provides novel polynucleotides and proteins encoded by such polynucleotides, along with therapeutic, diagnostic and research utilities for these polynucleotides and proteins.

BACKGROUND OF THE INVENTION
Technology aimed at the discovery of protein factors (including e.g., cytokines, such as Iymphokines, intc.re,ons, CSF;s and interleukins) has matured rapidly over the past decade.
The now routine hybridization cloning and expression cloning techniques clone novel polynucleotides "directly" in the sense that they rely on information directly related to the discovered protein (i.e., partial DNA/amino acid sequence of the protein in the case of hybridization cloning; activity of the protein in the case of expression cloning). More recent "indirect" cloning techniques such as signal sequence cloning, which isolates DNA sequences based on the presence of a now well-recognized secretory leader sequence motif, as well as various PCR-based or low stringency hybridization cloning techniques, have advanced the state 2 5 of the art by making available large numbers of DNA/amino acid sequences for proteins that are known to have biological activity by virtue of their secreted nature in the case of leader sequence cloning, or by virtue of the cell or tissue source in the case of PCR-based techniques.
It is to these proteins and the polynucleotides encoding them that the present invention is directed.

DETAILED DESCRIPTION
ISOLATED PROTEINS AND POLYNUCLEOTIDES
Nucleotide and amino acid sequences are reported below for each clone and protein 15 disclosed in the present application. In some instances the sequences are preliminary and may include some incorrect or ambiguous bases or amino acids. The actual nucleotide sequence of each clone can readily be determined by sequencing of the deposited clone in accordance with known methods. The predicted amino acid sequence (both full length and mature) can then be determined from such nucleotide sequence. The amino acid sequence of the protein 2 0 encoded by a particular clone can also be determined by expression of the clone in a suitable host cell, collecting the protein and determining its sequence.
For each disclosed protein applicants have identified what they have determined to be the reading frame best identifiable with sequence information avai]able at the time of filing.
Because of the partial ambiguity in reported sequence information, reported protein sequences 2 5 include "Xaa" designators. These "Xaa" designators indicate either ( I ) a residue which cannot be i<l,o.n~ifi~d because of nucleotide sequence ambiguity or (2) a stop codon in the determined nucleotide sequence where applicants believe one should not exist (if the nucleotide sequence were determined more accurately).
As used herein a "secreted" protein is one which, when expressed in a suitable host 3 0 cell, is transported across or through a membrane, including ll~"~,uu,L as a result of signal sequences in its amino acid sequence. "Secreted" proteins include without limitation proteins secreted wholly (e.g., soluble proteins) or partially (e.g., receptors) from the cell in which they are expressed. "Secreted" proteins also include without limitation proteins which are transported across the membrane of the endoplpasmic reticulum.

Fragments of the proteins of the present invention which are capable of exhibiting 5 biological aclivity are also encompassed by the present invention. Fragments of the protein may be in linear form or they may be cyclized using known methods, for example, as described in H.U. Saragovi, et al., Bio/Technology 10, 773-778(1992) and in R.S. McDowell, et al., J.
Amer. Chem. Soc. 1 14,9245-9253(1992), both of which are incorporated herein by reference.
Such fragments may be fused to carrier molecules such as immunoglobulins for many 10 purposes, including increasing the valency of protein binding sites. For example, fragments of the protein may be fused through "linker" sequences to the Fc portion of an immunoglobulin. For a bivalent form of the protein, such a fusion could be to the Fc portion of an IgG molecule. Other immunoglobulin isotypes may also be used to generate such fusions. For example, a protein - IgM fusion would generate a decavalent form of the protein 15 of the invention.
The present invention also provides both full-length and mature forms of the disclosed proteins. The full-length form of the such proteins is identified in the sequence lisling by translation of the nucleotide sequence of each disclosed clone. The mature form of such protein may be obtained by expression of the disclosed full-length polynucleotide (preferably 2 0 those deposited with ATCC) in a suitable m~lnm~ n cell or other host cell. The sequence of the mature form of the protein may also be deterrninable from the amino acid sequence of the full-length form.
The present invention also provides genes corresponding to the cDNA sequences disclosed herein. The cu-lc~ullding genes can be isolated in accordance with known methods 2 5 using the sequence information disclosed herein. Such methods include the pl~l)d~ ion of probes or primers from the disclosed sequence information for identification and/or amplification of genes in appropriate genomic libraries or other sources of genomic materials.
Where the protein of the present invention is ll-e,nbldne-bound (e.g., is a receptor), the present invention also provides for soluble forms of such protein. In such forms part or all of 3 0 the intracellular and tran~ ..,hldne domains of the protein are deleted such that the protein is fully secreted from the cell in which it is expressed. The intracellular and transmembrane domains of proteins of the invention can be identified in accordance with known techniques for determination of such domains from sequence information.
Species homologs of the ~ < lo~ed polynucleotides and proteins are also provided by 3 5 the present invention. Species homologs may be isolated and identified by making suitable probes or primers from the sequences provided herein and screening a suitable nucleic acid source from the desired species.
The invention also encompasses allelic variants of the disclosed polynucleotides or proteins; that is, naturally-occurring alternative fonns of the isolated polynucleotide which also 5 encode proteins which are identical, homologous or related to that encoded by the polynucleotides .
The isolated polynucleotide of the invention may be operably linked to an expression control sequence such as the pMT2 or pED expression vectors disclosed in Kaufman et al., Nucleic Acids Res. 19, 4485-4490 (l99l), in order to produce the protein recombinantly.
10 Many suitable expression control sequences are known in the art. General methods of expressing recombinant proteins are also known and are exemplified in R. Kaufman, Methods in Enzymology 18~, 537-566 (l990). As defmed herein "operably linked" means that the isolated polynucleotide of the invention and an expression control sequence are situated within a vector or cell in such a way that the protein is expressed by a host cell which has been 1 5 transformed (transfected) with the ligated polynucleotide/expression control sequence.
A number of types of cells may act as suitable host cells for expression of the protein.
M~mm~ n host cells include, for example, monkey COS cells, Chinese Hamster Ovary(CHO) cells, human kidney 293 cells, human epidermal A431 cells, human Colo205 cells,3T3 cells, CV-I cells, other transformed primate cell lines, normal diploid cells, cell strains derived 2 0 from m vitro culture of primary tissue, primary explants, HeLa cells, mouse L cells, BHK, HL-60, U937, HaK or Jurkat cells.
Alternatively, it may be possible to produce the protein in lower eukaryotes such as yeast or in prokaryotes such as bacteria. Potentially suitable yeast strains include Saccharomyces cerevisiae, Schizosaccharomyces pombe, Kluyveromyces strains, Candida, or 2 5 any yeast strain capable of expressing heterologous proteins. Potentially suitable bacterial strains include Escherichia coli, Bacillus subfilis~ Salmonella typhimurium, or any bacterial strain capable of e~ s~hlg heterologous proteins. If the protein is made in yeast or bacteria, it may be necessary to modify the protein produced therein, for example by phosphorylation or glycosylation of the appropriate sites, in order to obtain the functional protein. Such 3 0 covalent a~ mpnts may be accomplished using known chemical or enzymatic methods.
The protein may also be produced by operably linking the isolated polynucleotide of the invention to suitable control sequences in one or more insect expression vectors, and employing an insect expression system. Materials and methods for baculovirus/insect cell expression systems are commercially available in kit form from, e.g., Invitrogen, San Diego, 3 5 California, U.S.A. (the MaxBac(~ kit), and such methods are well known in the art, as . , . , . _ WO ~ "0~5 PCT/US97/14641 described in Summers and Smith, Texas Agricultural Experiment Station Bulletin No. ] 555 ~1987), incorporated herein by reference. As used herein, an insect cell capable of expressing a polynucleotide of the present invention is "transformed."
The protein of the invention may be prepared by culturing transformed host cells under 5 culture conditions suitable to express the recombinant protein. The resulting expressed protein may then be purified from such culture (i.e., from culture medium or cell extracts) using known purification processes, such as gel filtration and ion exchange chromatography. The purification of the protein may also include an affinity column containing agents which will bind to the protein; one or more column steps over such affinity resins as concanavalin A-10 agarose, heparin-toyopearl~ or Cibacrom blue 3GA Sepharose(~; one or more steps involving hydrophobic interaction chromatography using such resins as phenyl ether, butyl ether, or propyl ether; or immunoaffinity chromatography.
Alternatively, the protein of the invention may also be expressed in a form which will facilitate purification. For example, it may be expressed as a fusion protein, such as those of 15 maltose binding protein (MBP), glutathione-S-transferase (GST) or thioredoxin (TRX). Kits for expression and purification of such fusion proteins are commercially available from New England BioLab (Beverly, MA), Pharmacia (Piscataway, NJ) and InVitrogen, respectively.
The protein can also be tagged with an epitope and subsequent1y purified by using a specific antibody directed to such epitope. One such epitope ("Flag") is commercially available from 2 0 Kodak (New Haven, CT).
Finally, one or more reverse-phase high performance liquid chromatography (RP-HPLC) steps employing hydrophobic RP-HPLC media, e.g., silica gel having pendant methyl or other aliphatic groups, can be employed to further purify the protein. Some or all of the foregoing purification steps, in various combinations, can also be employed to provide a 25 substantially homogeneous isolated recombinant protein. The protein thus purified is s.lbsl~n~ lly free of other m~rnm~ n proteins and is defined in accordance with the present invention as an "isolated protein."
The protein of the invention may also be e~ ed as a product of transgenic animals, e.g., as a component of the milk of transgenic cows, goats, pigs, or sheep which are 3 0 ch ~Ir71~t ri7f d by somatic or germ cells Co~ lg a nucleotide sequence encoding the protein.
The protein may a3so be produced by known conventional chemical synthesis.
Methods for constructing the proteins of the present invention by synthetic means are known to those skilled in the art. The synlh.otic:~lly-constructed protein sequences, by virtue of sharing primary, secondary or tertiary structural andlor conformational characteristics with proteins 3 5 may possess biological properties in common therewith, including protein activity. Thus, they may be employed as biologically active or immunological substitutes for natural, purified proteins in screening of therapeutic compounds and in immunological processes for the development of antibodies.
The proteins provided herein also include proteins characteri~ed by amino acid 5 sequences similar to those of purified proteins but into which modification are naturally provided or deliberately engineered. For example, modifications in the peptide or DNA
sequences can be made by those skilled in the art using known techniques. Modifications of interest in the protein sequences may include the alteration, substitution, replacement, insertion or deletion of a selected amino acid residue in the coding sequence. For example, one or more 10 of the cysteine residues may be deleted or replaced with another amino acid to alter the conformation of the molecule. Techniques for such alteration, substitution, replacement, insertion or deletion are well known to those skilled in the art (see, e.g., U.S. Patent No.

4,51~,584). Preferably, such alteration, substitution, replacement, insertion or deletion retains the desired activity of the protein.
Other fragments and derivatives of the se~ n~ec of proteins which would be expected to retain protein activity in whole or in part and may thus be useful for screening or other immunological methodologies may also be easily made by those skilled in the art given the disclosures herein. Such modifications are believed to be encompassed by the present invention .

Research Uses and Utilities 3 0 The polynucleotides provided by the present invention can be used by the research community for various purposes. The polynucleotides can be used to express recombinant protein for analysis, characterization or therapeutic use; as markers for tissues in which the corresponding protein is preferentially expressed (either constitutively or at a particuJar stage of tissue differentiation or development or in disease states); as molecular weight markers on 3 5 Southern gels; as chromosome markers or tags (when labeled) to identify chromosomes or to , map related gene positions; to compare with endogenous DNA sequences in patients to identify potential genetic disorders; as probes to hybridize and thus discover novel, related DNA
sequences; as a source of information to derive PCR primers for genetic fingerprinting; as a probe to "subtract-out" known sequences in the process of discovering other novel polynucleotides; for selecting and making oligomers for attachment to a "gene chip" or other support, including for examination of expression patterns; to raise anti-protein antibodies using DNA immunization techniques; and as an antigen to raise anti-DNA antibodies or elicit another immune response. Where the polynucleotide encodes a protein which binds or potentially binds to another protein (such as, for example, in a receptor-ligand interaction), the polynucleotide can also be used in interaction trap assays (such as, for example, that described in Gyuris et al., Cell 75:791-803 (1993)) to identify polynucleotides encoding the other protein with which binding occurs or to identify inhibitors of the binding interaction.
The proteins provided by the present invention can similarly be used in assay todetermine biological activity, including in a panel of multiple proteins for high-throughput screening; to raise antibodies or to elicit another immune response; as a reagent (including the labeled reagent) in assays designed to quantitatively determine levels of the protein (or its receptor) in biological fluids; as markers for tissues in which the corresponding protein is preferentially expressed (either constitutively or at a particular stage of tissue differentiation or development or in a disease state); and, of course, to isolate correlative receptors or ligands.
2 0 Where the protein binds or potentially binds to another protein (such as, for example, in a receptor-ligand interaction), the protein can be used to identify the other protein with which binding occurs or to identify inhibitors of the binding interaction. Proteins involved in these binding interactions can also be used to screen for peptide or small molecule inhibitors or agonists of the binding interaction.

Cytokine and Cell Proliferation/Differentiation Activity A protein of the present invention may exhibit cytokine, cell proliferation (either 1 0 inducing or inhibiting) or cell differentiation (either inducing or inhibiting) activity or may induce production of other cytokines in certain cell populations. Many protein factors discovered to date, including all known cytokines, have exhibited activity in one or more factor dependent cell proliferation assays, and hence the assays serve as a convenient confirmation of cytokine activity. The activity of a protein of the present invention is evidenced by any one of a number of routine factor dependent cell proliferation assays for cell lines including, without limitation, 32D, DA2, DAlG, T10, B9, B9/11, BaF3, MC9/G, M+ (preB M+), 2E8, RB5, DAI, 123, T1165, HT2, CTLL2, TF-I, Mo7e and CMK.

Immune S~imnl~tin~ or Suy~ sin~ Activity A protein of the present invention may also exhibit immune stimulating or immune2 5 ~U~yplc~ lg activity, inr!u~iing without limitation the activities for which assays are described herein. A protein may be useful in the ll~,d~lllCIII of various immune ~ieficierlcie~ and disorders (including severe combined immunodeficiency (SCID)), e.g., in regulating (up or down) growth and proliferation of T and/or B Iymphocytes, as well as effecting the cytolytic activity of NK cells and other cell populations. These immune deficiencies may be genetic or be 3 0 caused by viral (e.g., HlV) as well as bacterial or fungal infections, or may result from ohl~ e disorders. More specifically, infectious diseases causes by viral, bacterial, fungal or other infection may be treatable using a protein of the present invention, including infections by HIV, hepatitis viruses, herpesviruses, mycobacteria, T ricl,n~.,ia spp., malaria spp. and various fungal infections such as candidiasis. Of course, in this regard, a protein of the present invention may also be useful where a boost to the immune system generally may be desirable, i.e., in the treatment of cancer.
Autoimmune disorders which may be treated using a protein of the present invention include, for example, connective tissue disease, multiple sclerosis, systemic lupus 5 erythematosus, rheumatoid arthritis, autoimmune pulmonary inflammation, Guillain-Barre syndrome, autoimmune thyroiditis, insulin dependent diabetes mellitis, myasthenia gravis, graft-versus-host disease and autoimmune inflammatory eye disease. Such a protein of the present invention may also to be useful in the treatment of allergic reactions and conditions, such as asthma (particularly allergic asthma) or other respiratory problems. Other conditions, 10 in which immune suppression is desired (including, for example, organ transplantation), may also be treatable using a protein of the present invention.
Using the proteins of the invention it may also be possible to immune responses, in a number of ways. Down regulation may be in the form of inhibiting or blocking an immune response already in progress or may involve preventing the induction of an immune response.
15 The functions of activated T cells may be inhibited by ~ul~pleSSillg T cell responses or by inducing specific tolerance in T cells, or both. Immuno~ul,p.~s~ion of T cell responses is generally an active, non-antigen-specific, process which requires continuous exposure of the T cells to the su~ cssive agent. Tolerance, which involves inducing non-responsiveness or anergy in T cells. is distinguishable from immuno~u~Jplession in that it is generally antigen-2 0 specific and persists after exposure to the tolerizing agent has ceased. Operationally, tolerancecan be ~lemonctrated by the lack of a T cell response upon reexposure to specific antigen in the absence of the tolerizing agent.
Down regulating or preventing one or more antigen functions (including without limitation B Iymphocyte antigen functions (such as, for example, B7)), e.g., preventing high 2 5 level Iymphokine synthesis by activated T cells, will be useful in situations of tissue, skin and organ transplantation and in graft-versus-host disease (GVHD). For example, blockage of T
cell function should result in reduced tissue destruction in tissue transplantation. Typically, in tissue transplants, rejection of the transplant is initiated through its recognition as foreign by T cells, followed by an immune reaction that destroys the transplant. The administration 3 0 of a molecule which inhibits or blocks interaction of a B7 Iymphocyte antigen with its natural ligand(s) on immune cells (such as a soluble, monomeric form of a peptide having B7-2 activity alone or in conjunction with a monomeric form of a peptide having an activity of another B Iymphocyte antigen (e.g., B7-I, B7-3) or blocking antibody), prior to ~ lantation can lead to the binding of the molecule to the natural ligand(s) on the immune cells without 35 ~ hlgtheco~ olIdingcostim~ orysignal. BlockingBIymphocyteantigenfunction W O9B/078S5 PCT~US97/14641 in this matter prevents cytokine synthesis by immune cells, such as T cells, and thus acts as an immuno~up~,essant. Moreover, the lack of costimulation may also be sufficient to anergize the T cells, thereby inducing tolerance in a subject. Induction of long-term tolerance by B
Iymphocyte antigen-blocking reagents may avoid the necessity of repeated administration of 5 these blocking reagents. To achieve sufficient immunosuppression or tolerance in a subject, it may also be necessary to block the function of a combination of B Iymphocyte antigens.
The efficacy of particular blocking reagents in preventing organ transplant rejection or GVHD can be assessed using animal models that are predictive of efficacy in humans.
Examples of appropriate systems which can be used include allogeneic cardiac grafts in rats 1 0 and xenogeneic pancreatic islet cell grafts in mice, both of which have been used to examine the immunosuppressive effects of CTLA41g fusion proteins in vivo as described in Lenschow et al., Science 257:789-792 (1992) and Turka et al., Proc. Natl. Acad. Sci USA, 89:11102-11105 ~1992). In addition, murine models of GVHD (see Paul ed.~ Fun(l~m.~llt:-l Immunology, Raven Press, New York, 1989, pp. 846-847) can be used to determine the effect of blocking 1 5 B Iymphocyte antigen function irl vivo on the development of that disease.
Blocking antigen function may also be therapeutically useful for treating autoimmune e~. Many ~-ltoimm~lne disorders are the result of hlayp.ul"iate activation of T cells that are reactive against self tissue and which promote the production of cytokines and autoantibodies involved in the pathology of the diseases. Preventing the activation of 2 0 autoreactive T cells may reduce or elimin~t~ disease symptoms. Administration of reagents which block costim~ tion of T cells by disrupting receptor:ligand interactions of B
Iymphocyte antigens can be used to inhibit T cell activation and prevent production of autoantibodies or T cell-derived cytokines which may be involved in the disease process.
Additionally, blocking reagents may induce antigen-specific tolerance of autoreactive T cells 2 5 which could lead to long-term relief from the disease. The efficacy of blocking reagents in preventing or alleviating autoimmune disorders can be determined using a number of well-characterized animal models of human autoimmune diseases. Examples include murine experimental autoimmune encephalitis, systemic lupus erythmatosis in MRL/lpr/lpr mice or NZB hybrid mice, murine .r..~uil..~ collagen arthritis, diabetes mellitus in NOD mice and 3 0 BB rats, and murine exp~lhll~..tal myasthenia gravis (see Paul ed., Funri~lnent~l Immunology, Raven Press, New York, 1989, pp. 840-856).
Upregulation of an antigen function (preferably a B Iymphocyte antigen function), as a means of up regulating immune responses, may also be useful in therapy. Upregulation of immune l~yonses may be in the form of enhancing an existing immune response or eliciting 3 5 an initial immune response. For example, ~-.hal-~ g an immune response through stim~ ting W O 98/07855 PCTrUS97/14641 B Iymphocyte antigen function may be useful in cases of viral infection. In addition, systemic viral diseases such as influenza, the common cold~ and encephalitis might be alleviated by the administration of stimulatory forms of B Iymphocyte antigens systemically.
Alternatively, anti-viral immune responses may be enhanced in an infected patient by 5 removing T cells from the patient, costimulating the T cells in vitro with viral antigen-pulsed APCs either expressing a peptide of the present invention or together with a stimulatory form of a soluble peptide of the present invention and reintroducing the in vitro activated T cells into the patient. Another method of enhancing anti-viral immune responses would be to isolate infected cells from a patient, transfect them with a nucleic acid encoding a protein of the 10 present invention as described herein such that the cells express all or a portion of the protein on their surface, and reintroduce the transfected cells into the patient. The infected cells would now be capable of delivering a costimulatory signal to, and thereby activate, T cells in vivo.
In another application, up regulation or enhancement of antigen function (preferably B Iymphocyte antigen function) may be useful in the induction of tumor immunity. Tumor 15 cells (e.g., sarcoma, melanoma, Iymphoma, leukemia, neuroblastoma, carcinoma) transfected with a nucleic acid encoding at least one peptide of the present invention can be administered to a subject to overcome tumor-specific tolerance in the subject. If desired, the tumor cell can be transfected to express a combination of peptides . For example, tumor cells obtained from a patient can be transfected ex vivo with an expression vector directing the expression of a 2 0 peptide having B7-2-like activity alone, or in conjunction with a peptide having B7-1-like activity and/or B7-3-like activity. The transfected tumor cells are returned to the patient to result in expression of the peptides on the surface of the transfected cell. Alternatively, gene therapy techniques can be used to target a tumor cell for transfection in vivo.
The presence of the peptide of the present invention having the activity of a B
2 5 Iymphocyte antigen(s) on the surface of the tumor cell provides the necessary costimulation signal to T cells to induce a T cell melliA~ed immune response against the transfected tumor cells. In addition, tumor cells which lack MHC class I or MHC class II molecules, or which fail to reexpress sufficient amounts of MHC class I or MHC class Il molecules, can be transfected with nucleic acid encoding all or a portion of (e.g., a cytolula~l,~ic-domain truncated 3 0 portion) of an MHC class I a chain protein and ,B~ microglobulin protein or an MHC class 11 a chain protein and an MHC class II ,~ chain protein to thereby express MHC class I or MHC
class II proteins on the cell surface. Expression of the appropriate class I or class II MHC in conjunction with a peptide having the activity of a B Iymphocyte antigen (e.g., B7-1, B7-2, B7-3) induces a T cell m,oriiA~d immune response against the transfected tumor cell. Optionally, 3 5 a gene çncodirlg an au~ ce construct which blocks expression of an MHC class Il associated W O 9~Uro~S PCTAJS97/14641 protein, such as the invariant chain, can also be cotransfected with a DNA encoding a peptide having the activity of a B Iymphocyte antigen to promote presentation of tumor associated antigens and induce tumor specific immunity. Thus, the induction of a T cell mefti~ted immune response in a human subject may be sufficient to overcome tumor-specific tolerance in the subject.

ADMINISTRATION AND DOSING
A protein of the present invention (from whatever source derived, including without 3 5 limitation from recombinant and non-recombinant sources) may be used in a pharmaceutical W O~ lo~5 PCTAUS97/14641 composition when combined with a pharmS~eutic~lly acceptable carrier. Such a composition may also contain (in addition to protein and a carrier) diluents, fillers, salts, buffers, stabilizers, solubilizers, and other materials well known in the art. The term "pharrnaceutically acceptable" means a non-toxic material that does not interfere with the effectiveness of the 5 biological activity of the active ingredient(s). The characteristics of the carrier will depend on the route of ~lmini~tratjon. The pharm:l~elltic~l composition of the invention may also contain cytokines, Iymphokines, or other hematopoietic factors such as M-CSF, GM-CSF, TNF, IL-I, IL-2, IL-3, IL-4, IL-5, IL-6, L-7, IL-8, L-9, IL-IO, L-11, IL-12, IL-13, IL-14, IL-15, IFN, TNFO, TNFI, TNF2, G-CSF, Meg-CSF, thrombopoietin, stem cell factor, and erythropoietin.
10 The pharmaceutical composition may further contain other agents which either enhance the activity of the protein or compliment its activity or use in treatment. Such additional factors and/or agents may be included in the pha----ac~uLical composition to produce a synergistic effect with protein of the invention, or to minimi7f side effects. Conversely, protein of the present invention may be included in formulations of the particular cytokine, Iymphokine, other 15 hematopoietic factor, thrombolytic or anti-thrombotic factor, or anti-inflammatory agent to minimize side effects of the cytokine, Iymphokine, other hematopoietic factor, thrombolytic or anti-thrombotic factor, or anti-inflammatory agent.
A protein of the present invention may be active in multimers (e.g., heterodimers or homodimers) or complexes with itself or other proteins. As a result, pharmaceutical 2 0 compositions of the invention may comprise a protein of the invention in such multimeric or complexed form.
The l ha..n~ ic~l composition of the invention may be in the form of a complex of the protein(s) of present invention along with protein or peptide antigens. The protein and/or peptide antigen will deliver a 5tim~ ry signal to both B and T Iymphocytes. B Iymphocytes 2 5 will respond to antigen through their surface immunoglobulin receptor. T Iymphocytes will respond to antigen through the T cell receptor (TCR) following presentation of the antigen by MHC proteins. MHC and structurally related proteins including those encoded by class I and class II MHC genes on host cells will serve to present the peptide antigen(s) to T Iymphocytes.

As used herein, the term "therapeutically effective amount" means the total amount of each active component of the pl~ llic~l composition or method that is sufficient to show 1 0 a m~.~ningful patient benefit, i.e., ll~aLlnent~ healing, prevention or amelioration of the relevant medical condition, or an increase in rate of treatment, healing, prevention or amelioration of such conditions. When applied to an individual active ingredient, zlrl ninictf red alone, the term refers to that ingredient alone. When applied to a combination, the term refers to combined amounts of the active ingredients that result in the therapeutic effect, whether :lflminict~red in 15 combination, serially or simultaneously.
In practicing the method of tlt;allllent or use of the present invention, a therapeutically effective amount of protein of the present invention is ;~drrinistt~red to a mammal having a condition to be treated. Protein of the present invention may be :~lminictçred in accordance with the method of the invention either alone or in combination with other therapies such as 20 tre~tmf ntc employing cytokines, Iymphokines or other hematopoietic factors. When co-~minic~red with one or more cytokines, Iymphokines or other hematopoietic factors, protein of the present invention may be z~-lminictered either simultaneously with the cytokine(s), Iymphokine(s), other hematopoietic factor(s), thrombolytic or anti-thrombotic factors, or sequentially. If ~Aminictçred sequentially, the attending physician will decide on the 25 app,up,-ate sequçnce of ~ ini~lr.ling protein of the present invention in combination with cytokine(s), Iymphokine(s), other hematopoietic factor(s), thrombolytic or anti-thrombotic factors.
A~minictration of protein of the present invention used in the pharml~eu~ic~l composition or to practice the method of the present invention can be carried out in a variety 3 0 of conventional ways, such as oral ingestion, inhalation, topical application or cutaneous, SUt~C~ OUS, i~ Iilulleal, pa~t;nl~l~l orintravenous injection. Intravenous administration to the patient is l"~l~lled.
When a therapeutically effective amount of protein of the present invention is ~h..il~ ~l~d orally, protein of the present invention will be in the form of a tablet, capsule, 3 5 powder, solution or elixir. When a-lminict~red in tablet form, the phal~ac~ulical composition W O 98/07855 PCT~US97/14641 of the invention may additionally contain a solid carrier such as a gelatin or an adjuvant. The tablet, capsule, and powder contain from about 5 to 95% protein of the present invention, and preferably from about 25 to 90% protein of the present invention. When administered in liquid form, a liquid carrier such as water, petroleum, oils of animal or plant origin such as peanut oil, 5 mineral oil, soybean oil, or sesame oil, or synthetic oils may be added. The liquid form of the pharmaceutical composition may further contain physiological saline solution, dextrose or other saccharide solution, or glycols such as ethylene glycol, propylene glycol or polyethylene glycol. When ~flminicl~red in liquid forrn, the pharmaceutical composition contains from about 0.5 to 90% by weight of protein of the present invention, and preferably from about l 10 to 50% protein of the present invention.
When a therapeutically effective amount of protein of the present invention is administered by intravenous, cutaneous or subcutaneous injection, protein of the present invention will be in the form of a pyrogen-free, p~.,t~ lly acceptable aqueous solution. The pl~paldtion of such parenterally acceptable protein solutions, having due regard to pH, 15 isotonicity, stability, and the like, is within the skill in the art. A preferred pharmaceutical composition for intravenous, cutaneous, or subcutaneous injection should contain, in addition to protein of the present invention, an isotonic vehicle such as Sodium Chloride Injection, Ringer's Injection, Dextrose Injection, Dextrose and Sodium Chloride Injection, I ~ct~ted Ringer's Injection, or other vehicle as known in the art. The pharmaceutical composi~ion of 2 0 the present invention may also contain stabilizers, preservatives, buffers, antioxidants, or other additives known to those of skill in the art.
The amount of protein of the present invention in the pl.d....aceutical composition of the present invention will depend upon the nature and severity of the condition being treated, and on the nature of prior treatments which the patient has undergone. Ultimately, the 2 5 attending physician will decide the amount of protein of the present invention with which to treat each individual patient. Initially, the attending physician will administer low doses of protein of the present invention and observe the patient's response. Larger doses of protein of the present invention may be ~(lminict~red until the optimal therapeutic effect is obtained for the patient, and at that point the dosage is not increased further. It is contemplated that the 3 0 various pharmaceutical compositions used to practice the method of the present invention should contain about 0.01 llg to about l OO mg (preferably about O. l ~lg to about 10 mg, more preferably about 0. l ~g to about l mg) of protein of the present invention per kg body weight.
The duration of intravenous therapy using the pharmaceutical composition of the present invention will vary"lepen-ling on the severity of the disease being treated and the 3 5 condition and potential idiosyncratic response of each individual patient. It is contemplated W O g~ o~5 PCTflUS97/14641 that the duration of each application of the protein of the present invention will be in the range of ] 2 to 24 hours of continuous intravenous administMtion. Ultimately the attending physician will decide on the appropriate duration of intravenous therapy using the pharmaceutical composition of the present invention.
Protein of the invention may also be used to immunize animals to obtain polyclonal and monoclonal antibodies which specifically react with the protein. Such antibodies may be obtained using either the entire protein or fragments thereof as an immunogen. The peptide immunogens additionally may contain a cysteine residue at the carboxyl terminus, and are conjugated to a hapten such as keyhole limpet hemocyanin (KLH). Methods for synthesizing such peptides are known in the art, for example, as in R.P. Merrifield, J. Amer.Chem.Soc. 85, 2149-2154 (1963); J.L. Krstenansky, et al., FEBS Lett. 211, 10 (1987). Monoclonal antibodies binding to the protein of the invention may be useful diagnostic agents for the immunodetection of the protein. Neutralizing monoclonal antibodies binding to the protein may also be useful therapeutics for both conditions associated with the protein and also in the treatment of some forms of cancer where abnormal expression of the protein is involved. In the case of cancerous cells or leukemic cells, neutralizing monoclonal antibodies against the protein may be useful in detecting and preventing the metastatic spread of the cancerous cells, which may be me(li~d by the protein.
For cu~ o~ilions of the present invention which are useful for bone, cartilage, tendon or ligament regeneration, the therapeutic method includes administering the composition topically, systematically, or locally as an implant or device. When A~lminictPred, the therapeutic composition for use in this invention is, of course, in a pyrogen-free, physiologically acceptable form. Further, the composition may desirably be encapsulated or injected in a viscous form for delivery to the site of bone, cartilage or tissue damage. Topical 2 5 a-lministration may be suitable for wound healing and tissue repair. Therapeutically useful agents other than a protein of the invention which may also optionally be included in the composition as described above, may alternatively or additionally, be administered simultaneously or sequentially with the composition in the methods of the invention.
Preferably for bone and/or cartilage formation, the col"~uo~ilion would include a matrix capable 3 0 of delivering the protein-containing composition to the site of bone and/or cartilage damage, providing a structure for the developing bone and cartilage and optimally capable of being resorbed into the body. Such matrices may be formed of materials presently in use for other implanted medical applications.
The choice of matrix material is based on biocompatibility, biodegradability, 3 5 mech~nir~l properties, cosmetic a~ e~nce and interface properties. The particular W O 98/07855 PCT~US97/14641 application of the co~ )osilions will define the d~ lid~t~ formulation. Potential matrices for the compositions may be biodegradable and chemically defined calcium sulfate, tricalciumphosphate, hydroxyapatite, polylactic acid. polyglycolic acid and polyanhydrides.
Other potential materials are biodegradable and biologically well-defined, such as bone or 5 dermal collagen. Further matrices are comprised of pure proteins or extracellular matrix components. Olh~r potential matrices are nonbiodegradable and chemically defined, such as sintered hydroxapatite, bioglass, alumin~ , or other ceramics. Matrices may be comprised of combinations of any of the above mentioned types of material, such as polylactic acid and hydroxyapatite or collagen and tricalciumphosphate. The bioceramics may be altered in 10 composition, such as in calcium-aluminate-phosphate and processing to alter pore size, particle size, particle shape, and biodegradability.
Presently preferred is a 50:50 (mole weight) copolymer of lactic acid and glycolic acid in the form of porous particles having diameters ranging from 150 to 800 microns. In some applications, it will be useful to utili~e a sequestering agent, such as carboxymethyl cellulose 15 or autologous blood clot, to prevent the protein compositions from disassociating from the matrix.
A p.~r~..ed family of seq~l~Cl~ring agents is cellulosic materials such as alkylcelluloses (including hydroxyalkylcelluloses), including methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropyl-methylcellulose, and 2 0 carboxymethylcellulose, the most preferred being cationic salts of carboxymethylcellulose (CMC). Other preferred sequestering agents include hyaluronic acid, sodium alginate, poly(ethylene glycol), polyoxyethylene oxide, carboxyvinyl polymer and poly(vinyl alcohol).
The amount of se~lue~ lg agent useful herein is 0.5-20 wt%, preferably l-l0 wt% based on total formulation weight, which represents the amount necessary to prevent desorbtion of the 2 5 protein from the polymer matrix and to provide appropriate handling of the composition, yet not so much that the progenitor cel}s are prevented from infiltrating the matrix, thereby providing the protein the opportunity to assist the osteogenic activity of the progenitor cells.
In further compositions, proteins of the invention may be combined with other agents beneficial to the Lr~dllnent of the bone and/or cartilage defect, wound, or tissue in question.
3 0 These agents include various growth factors such as epidermal growth factor (EGF), platelet derived growth factor (PDGF), "~.~rO- ...hlg growth factors (TGF-~ and TGF-,~), and insulin-like growth factor (IGF).
The th~ld~,~. lic compositions are also presently valuable for veterinary applications.
Particularly domestic animals and thoroughbred horses, in addition to humans, are desired 3 5 patients for such l~alm~.-t with proteins of the present invention.
