Definitions
- the present invention is related to the field of receptor molecules and complexes. More particularly, the present invention is related to a new polypeptide receptor for interleukin-2 (IL-2) having a molecular weight of about 70-75,000, which is also a component of the high affinity IL-2 receptor. The invention further relates to antibodies against this new polypeptide and recombinant interleukins which have binding affinity for the new receptor.
- IL-2 interleukin-2
- the first category includes those types of cells which must express high affinity IL-2 receptors and express the Tac antigen (defined by anti-Tac monoclonal antibody, denoted herein as p55) for interaction with IL-2 and are designated herein as "Tac-positive" cells.
- An example of a Tac-positive cell is the activated T cell.
- the second category includes those types of cells which do not express high affinity IL-2 receptors or p55, but interact with IL-2 by expressing a novel glycoprotein, designated herein as "p70-75", which is distinct and different from p55.
- p55 negative p70-75 expressing cells are resting large granular lymphocytes (LGL), natural killer (NK) and precursors of lymphokine-activated-killer (LAK) cells.
- LGL lymphocytes
- NK natural killer
- LAK lymphokine-activated-killer
- an object of the present invention to provide a new p70-75 peptide having binding affinity, for IL-2 at an epitopic site different from that of the p55. It is a further object of the present invention to provide antibodies having specific binding affinity for p70-75. It is another object of the present invention to provide an altered IL-2 molecule, designated "IL-2W 1 ", having epitopes required for binding with the p70-75 but devoid of epitopes required for binding with the p55.
- IL-2W 2 altered IL-2 molecule, designated "IL-2W 2 ", having epitopes required for binding with the p55 peptide but devoid of epitopes required for binding with the p70-75 peptide. It is an additional object of the present invention to provide a method of producing LAK cells by reacting LGL cells with IL-2W 1 . It is yet another object of the present invention to provide a method of destroying LAK-susceptible cells by contacting said LAK-susceptible cells with LAK cells produced by reacting LGL cells with IL2-W 1 .
- a still further object of the present invention is to provide a pharmaceutical composition comprising an effective amount of LAK cells, produced by reacting LGL cells with IL2-W 1 , to destroy LAK-susceptible cells; and a pharmaceutically acceptable carrier.
- This combination may optionally further contain IL2-W 1 in an amount sufficient to maintain sustained killer activity of LAK cells.
- Figure 1 is a schematic representation of a multichain model of IL-2 receptor in which an independently .existing p55 or p70-75 represent low and intermediate affinity receptors, respectively, whereas high affinity receptors are present when both p55 and p70-75 are associated in a receptor complex.
- Activated T cells as shown in the center express both p55 and p70-75 and manifest high affinity receptors. Such high affinity receptors are required for certain T cell functions.
- lymphokine activated killer precursor cells and natural killer cells express only the p70-75 peptide as shown on the left and manifest intermediate affinity receptors. Such cell types can respond to IL-2 utilizing the p70-75 IL-2 binding peptide alone.
- a polypeptide characterized by a molecular weight of about 70-75,000 and which binds specifically to an epitope contributed to by amino acids 1-25 of interleukin 2.
- all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, the preferred methods and materials are now described. All publications mentioned hereunder are incorporated herein by reference. Of course, apart from being distinct from the p55, the p70-75 of the present invention has the following additional properties.
- LGL cells obtained from normal human peripheral blood express the p70-75 peptide alone, that is this cell population expresses an IL-2 receptor (P70-75), which is not recognized by anti-Tac monoclonal antibody.
- P70-75 an IL-2 receptor
- LGL leukemic cells manifest only p70-75 and not p55.
- IL-2 dependent cell line such as LGL leukemia cells
- Spleen cell suspension are obtained by teasing of the spleen and lysis of red blood ceils with standard ACK lysing buffer (155mM NH 4 CI, 10mM KHCO 3 , CClmM Na2 ⁇ EDTA and distilled water). Cell fusions are carried out according to the standard procedure of Kohler and Milstein (Nature, 256:495, 1975). 150 million spleen cells are fused with 3 x 10 7 NSl mouse myeloma cells using 30% polyethylene glycol (MW 1,000, Backers, Philipsburg, N.J.) dissolved in Delbecco's Modified Eagle's Media.
- Cells are resuspended in medium and are distributed into flat bottom microtiter plates where they are selected by feeding with HAT media containing 0.1 mM hypoxanthine, 0.4 uM aminopterin, 16 mM thymidine. Fifteen days after cell fusion the culture supernatants from the wells are tested for antibody activity by an ELISA technique to determine reactivity aginst cell lines (e.g. MLA 144 and HUT 78) that express the p70-75 and non-reactivity against cell lines (e.g. MT-1) that do not express p55. After screening, hybridoma cultures that showed an appropriate pattern of reactivity, are expanded and cloned by a limiting dilution method.
- HAT media containing 0.1 mM hypoxanthine, 0.4 uM aminopterin, 16 mM thymidine.
- Blocking antibodies are defined by their ability to inhibit the binding of radioactive IL-2 to cell lines such as MLA 144 that express p70-75 but not p55.
- Non-blocking antibodies are defined by their ability to precipitate radiolabelled IL-2 crosslinked to p70-75.
- radiolabelled IL-2 can be easily prepared by routine standard procedures well known in the art.
- anti-idiotype antibodies to antibodies that are directed toward IL-2 are prepared.
- the immunogen is an antibody to the part of the IL-2 molecule that is involved in IL-2 binding to the p70-75.
- anti-IL-2 antibodies are defined by their ability to bind to unbound IL-2 or IL-2 bound to p55 but are unreactive to IL-2 bound by crosslinking to p70-75.
- Antibodies to the idiotype of such antibodies toward IL-2 also crossreact with the part of the p70-75 IL-2 binding receptor involved in IL-2 binding.
- the procedure for the production of a monoclonal antibody vide supra is utilized with the exception that use is made of the monoclonal antibody directed toward IL-2 as the immunogen in lieu of the cell lines expressing p70-75.
- cytotoxic agents for instance with ricin A or salmonella toxin or cytotoxic radionuclides and the like
- antibodies of the present invention are useful in neutralizing or killing p70-75 expressing cells such as p70-75 expressing leukemias and those conditions (such as autoimmune disease or organ allograft protocols) which arise due to the abnormal interaction or pathophysiology caused by the expression of p70-75.
- the p70-75 is obtained from any of the Tac-negative, IL-2 responsive cell lines, a few examples of which have been mentioned herein above.
- Anti-p70-75 and a control monoclonal UPC10 are used to generate immunoaffinity columns. Imunoaffinity columns are prepared by coupling purified anti-p70-75 and UPC10 monoclonal antibodies to cyanogen bromide activated sepharose.
- HUT-78 cells are grown in 10% fetal bovine serum/RPMI media collected by ultrafiltration washed twice in phosphate buffered saline and solubized in an extraction buffer containing 10mM Tris pH 7.4, 0.15 M sodium chloride 100 micrograms ml -1 phenylmethyl sulfonylfluoride (PMSF) 1% Triton-X-100. Extracts are centrifuged and the top lipid layer is discarded. The remaining supernatant is passed over a UPC10 column four times and then over an anti-p70-75 column three times.
- PMSF phenylmethyl sulfonylfluoride
- the anti-p70-75 column is washed with extraction buffer, then with 10mM Tris pH 7.5, 0.5M NaCl, 1% Triton-X-100, then with 10mM Tris pH 7.5, 0.2% triton-X-100 and then with 10mM of Tris pH 7.5.
- the anti-p70-75 column is then eluted with 2.5% (v/v) acetic acid.
- the eluted protein is lyophilized, resuspended in phosphate buffered saline and an aliquot is analyzed on SDS-polyacrylamide gels under reducing conditions: Gels are silver stained to assess the yield and purity.
- Preparation of Altered IL-2 IL-2W 1 molecules that bind to p70-75 alone and IL-2W 2 molecules that bind to p55 alone are generated by constructing mutants by site directed mutagenesis.
- 18 bases long oligonucleotide chains are synthesized using commercially available DNA synthesizers.
- the oligonucleotides are complementary to the DNA of the IL-2 gene that has been cloned and is available with the exception that they contain 1-2 mismatches.
- the slightly mismatched short DNA segments can function as primers for DNA extention when added to the circular single stranded chains of M13 phage.
- the resulting complete double stranded DNA will be perfectly complementary except for the mismatched bases at the primer site.
- DNA replication After entry into E. coli, DNA replication generates two types of daughter DNA strands; wild type strands and mutant strands, the latter containing changes imposed by the mismatched primer.
- the strands can be easily distinguished by the way they bind the corresponding oligonucleotides. Wild type daughter DNAs bind more strongly to wild type oligonucleotide while the short DNA segment that primes the mutant sequences will bind best to the mutated progeny strands that are to be selected.
- mutations are generated in the peptide region involved in binding to p55.
- IL-2W 2 that binds to p55 but not to the ⁇ 70-75 peptide is generated using a slightly mismatched oligonucleotide that has a mismatch at the bases encoding the amino acids involved in binding to p70-75 but not at the site involved in binding to p55.
- Activation of NK or LAK cells To activate natural killer (NK) and lymphokine activated killer (LAK) cells without activating T lymphocytes, IL-2W 1 is selectively and advantageously employed. At present lymphokine activated killer cells are generated by incubating peripheral blood mononuclear cells with natural IL-2. The activated cells are then readministered to the patient along with daily intravenous doses of IL-2.
- IL-2W 1 which interacts only with the p70-75, is substituted in vitro and/or in vivo for natural IL-2 for the generation and maintenance of LAK cells.
- IL-2W 1 binds to the p70-75 which is the receptor for IL-2 on large granular lymphocytes (the precursors of natural killer and lymphokine activated killer cells) and is sufficient for IL-2 activation of these cells.
- many T cell functions depend on the simultaneous binding of IL-2 to the p55 and p70-75 IL-2 binding peptides of the high affinity receptor complex. Since IL-2W 1 does not bind to the Tac peptide, it does not activate T-cells at the concentrations used. Thus, IL-2W 1 activates the large granular lymphocytes to become effective natural killer and lymphokine activated killer cells without simultaneously activating T lymphocytes to become activated cells that synthesize toxic lymphokines.
- lymphokine IL-2W 1 in contrast to natural IL-2, the desired lymphokine activated killer cells to destroy the tumor cell populations are activated without activating T lymphocytes and their toxic lymphokine.
