JP4044605B2 - Antigenic protein from Malassezia - Google Patents

Description

  The present invention relates to a novel antigenic protein isolated from and purified from Malassezia, which can be used for diagnosis, treatment and prevention of allergic diseases and infectious diseases caused by Malassezia, the antigenic fragment thereof, and the antigenic protein Alternatively, it relates to an antibody against an antigenic fragment.

  Furthermore, the present invention relates to a recombinant Malassezia antigenic protein, a gene encoding the antigenic protein, and an epitope of the protein.

  Many allergic diseases are sensitized to the causative antigen of the disease, so that IgE antibody (reagin antibody) specific to the antigen (allergen) is produced in the serum and tissues, and then exposed to the antigen again. When combined with IgE bound to mast cells or basophils and specific allergens, IgE crosslinks on the cell surface, producing the physiological effect of IgE-antigen interaction. These physiological effects include the release of histamine, serotonin, heparin, eosinophil migration factor or various leukotrienes. This causes long-term bronchial smooth muscle contraction. These released substances are chemical mediators and cause allergic symptoms caused by the combination of IgE and specific allergens. Allergen effects appear through them. These effects can occur systemically or locally depending on the route by which the antigen enters the body and the pattern of IgE deposition on mast cells or basophils. Local symptoms generally occur on the epithelial surface where allergens enter the body. A systemic effect is the result of an IgE-basophil response to antigens in blood vessels, typically anaphylactic shock. Helper T (Th) cells play an important role in these series of reactions. Among various cytokines produced by Th cells activated by antigen stimulation, IL4 promotes IgE production.

  There are a wide variety of substances that cause allergic symptoms in humans. Until now, allergens have been treated as aggregates of many substances represented by pollen or indoor dust. In recent years, as a result of advances in separation and purification techniques and methods for evaluating allergen activity, it has been clarified that allergens are composed of a single substance or several main substances. In particular, it has made rapid progress in cedar pollen, mites, cat allergens, etc. Major allergens such as Cry j 1, Cry j 2 from cedar pollen, Der f 1, Der f 2, Der f 3, from tick and Fel d 1 from cat Has been isolated. Furthermore, genes encoding these allergen proteins have also been isolated, and a large amount of pure allergen proteins can be prepared by genetic engineering techniques.

  When diagnosing allergic diseases, it is necessary to first identify the causative antigen. To this end, we first tested more than 100 commercially available antigen extracts, sometimes even our own, by intradermal testing using suspicious antigen extracts. It is carried out. When an antigen having high possibility as a causative antigen is found, the antigen can be identified by measuring IgE antibody titer in serum by RAST method or the like, induction test, or histamine release test using whole blood or lymphocytes. However, since a clear titer is not defined for these antigen extracts, attention should be paid to the risk of anaphylaxis induction during use. Antihistamines, steroidal anti-inflammatory drugs, mediator release inhibitors, etc. are used to treat allergic diseases, but desensitization therapy using antigens identified by diagnosis is an excellent treatment. . However, with current desensitization therapy, it is necessary to administer the antigen solution intradermally in small doses once or twice a week, increase the dose over 3 to 4 months, increase the maintenance dose, and continue to administer for 1 to 3 years. is there. If the amount can be increased easily, it can be expected that an excellent therapeutic effect can be obtained more easily. However, since the titer of the antigen to be used is not clear as described above, and since the antigen is accompanied by many impurities, serious side effects may occur, and the use is greatly limited.

  Known bacteria belonging to the genus Malassezia (hereinafter abbreviated as M.) include M. furfur (also called Pityrosporum ovale and Pityrosporum orbiculare), M. pachydermatis, M. sympodialis, and the like. Malassezia is said to be resident in various animal and human body surfaces, and its pathogenicity and role in allergic diseases have been studied for a long time. About pathogenicity, it is suspected as causative bacteria such as dermatitis, folding screen, folliculitis, dandruff. It is also suspected to be associated with allergic diseases such as atopic dermatitis, and is likely to be involved as a causative bacterium.

  Currently, antigens derived from Malassezia are commercially available, but these are unpurified or partially purified products obtained from a culture of M. furfur (hereinafter referred to as M. furfa), and of course, proteins, sugars, It is thought to be a complex mixture including lipids.

  Conventionally, as an allergenic protein derived from Malassezia contained in the antigen extract thus obtained, a crude extract derived from Malassezia is separated by SDS-polyacrylamide gel electrophoresis (PAGE), and then allergic patients' Many IgE-binding proteins such as 87, 76, 67, 45, 37, 28, 25, 14, 13 kDa detected by immunoblotting using IgE antibodies in serum have been reported as allergenic substances ( Non-patent documents 1 to 3). Since the proteins produced by Malassezia are so diverse, separation by SDS-PAGE alone is not sufficient, and the single protein band reported in SDS-PAGE is a uniform protein. I can't think of it. That is, since there are usually multiple proteins showing the same protein band on SDS-PAGE, even if an IgE-binding protein shows a single protein band, it is different from many other proteins contained in that band. They need to be separated, and for that purpose it is necessary to combine other effective separation methods. Furthermore, in order to be used for diagnostic and therapeutic purposes, it is necessary to isolate an antigenic protein, clarify the antigenicity using multiple patient sera, identify the major allergen, It is necessary to establish a production method for supplying an antigenic protein whose protein chemistry is clarified. Therefore, it is necessary to repeat separation by various chromatographies and measurement of antigen activity to isolate a uniform and single antigenic protein. For the final protein obtained, in addition to SDS-PAGE, In addition, it is necessary to confirm unity by ion exchange chromatography and unity by isoelectric focusing.

  However, according to the various reports, the substances observed on the SDS-PAGE are treated as if they were each a single IgE-binding protein. However, in fact, no one has succeeded in isolating and purifying them, and no consideration has been given as to how the bands are unrelated and a mixture of many proteins. Therefore, of course, there is no example in which an IgE-binding protein is isolated from the complex mixture, and further, antigenicity is confirmed using the serum of allergic patients as the isolated protein. In addition, no protein chemistry or amino acid sequence has been reported. For this reason, the differences between IgE-binding proteins and the relevance (one is a degradation product by the other protease, etc.) seen in the above report are completely unknown.

As described above, although Malassezia has attracted attention as a causative fungus of allergic diseases including atopic dermatitis, an IgE-binding protein alone is obtained from a crude extract which is a complex protein mixture thereof. No one has succeeded in refining. Of course, antigenicity has not been confirmed using serum from allergic patients as an isolated protein. In addition, no protein chemistry or amino acid sequence has been reported. There are also no reports of isolation of the gene encoding the protein.

  In order to diagnose the possibility of causative bacteria, in addition to microbiological culture tests, skin tests using crude antigens that are malassezia cell extracts as described above, induction tests, RAST method and histamine release measurement, etc. Diagnosis is made by quantitative tests of various IgE antibodies. However, since this crude antigen contains many kinds of impurities, an accurate diagnosis cannot be made. In addition, there is a risk of side effects when used in skin tests and provocation tests. Furthermore, since it is associated with the risk of anaphylaxis in order to be used for desensitization therapy, which is a useful treatment for allergic diseases, the dose of this crude antigen is extremely limited, and a therapeutic effect cannot be expected, It is also difficult to use as a vaccine to protect against infection. To date, there has been no successful isolation of a purified, pure antigen derived from Malassezia, and there has been a great difficulty in diagnosing and treating allergic diseases and infections caused by Malassezia.

  Furthermore, the diagnosis using these purified antigenic proteins correlates with the results of the conventional skin test using the antigen extract, which is a crude malassezia antigen, and the diagnosis by the RAST method. That is, many of the positive patients in the skin test using the crude antigen are positive for IgE antibody titer against the malassezia crude antigen. In addition, more than 50% of patients with positive IgE antibody titers against these crude antigens have high IgE antibody titers against the isolated and purified purified antigenic protein of the present invention (Examples described later). (See Table 2 and Table 3).

  In addition, the purified antigenic protein of the present invention can reduce the allergic response of the administered patient to malassezia when administered to a patient with malassezia allergy.

  Furthermore, in the present invention, a functionally equivalent antigenic protein having immunologically equivalent properties to the purified antigenic protein as described above is also provided. For example, as functional equivalents having immunologically equivalent properties to the 13 types of purified antigenic proteins described above, for example, functional equivalents of various M. furfurs, and other Malassezia fungi other than M. furfur are also included in the present invention. include. That is, MF-2 is a peroxisomal membrane protein PMP-20 [L. L. Garrard et al., Journal Biological Chemistry (Vol. 23, pp. 13929-13937 (1989)) and homology, and derived from malassezia with similar immunological properties. Proteins are included in the present invention. MF-3 and MF-4 are different proteins, but both have homology with iron / manganese-superoxide dismutase [T. Matsumoto et al., Biochemistry, Vol. 30, pages 3210-3216 (1991); L. ML Ludwig et al., Journal of Molecular Biology (J. Mol. Biol.), 219, 335-358 (1991)], and MF-5 is dihydrolipoamide dehydrogenase (DLDH), MF -6 is malate dehydrogenase (MDH), MF-13 is homologous to cyclophilin, respectively, and proteins derived from malassezia having similar immunological properties are also included in the present invention.

  It should be noted that the stability and / or the desired reactivity is enhanced, that is, for diagnostic purposes, the specific binding between antigen and antibody is enhanced, and for therapeutic purposes, allergic reactions are attenuated or enzyme activity is lost. For this purpose, the purified antigenic protein of the present invention may be modified and derivatized, or the polyethylene glycol (PEG) method [Wie et al., International Archives of Allergy and Applied Immunology (Int. Arch. Allergy Appl. Immunol. 64, pp. 84-99 (1981)]. For protein modification, pyridylethylation, reduction, alkylation, acylation, chemical coupling to a suitable carrier Mild formalin treatment or guanidine hydrochloride treatment is also included.

(2) Antigenic fragment of the present invention The antigenic fragment of the present invention is an antigenic fragment derived from a purified antigenic protein characterized by having an antigenic epitope contained in the purified antigenic protein. For example, MF-1, MF-2, MF-3, MF-4, MF-5, MF-6, MF-7, MF-8, MF-9, MF-10, MF-11, MF-12, Examples thereof include antigenic fragments derived from purified antigenic proteins containing at least one antigenic epitope contained in MF-13 and the like. Among them, those containing at least one T cell epitope or B cell epitope are preferable. The antigenic fragments of the present invention can be used to produce immune responses in mammals, particularly humans, such as T cell responses and / or lymphokine secretion, such as stimulation of minimal amounts of IgE, IgE binding, induction of IgG and IgM antibody production, or proliferation and A fragment of purified antigenic protein derived from Malassezia that causes induction of T cell anergy and the like is included.

  When the antigenic fragment of the present invention is used for therapeutic purposes, it is desirable that the T cell responsive activation action is small or that the T cell anergy action is induced. In addition, the antigenic fragment of the present invention has substantially no binding ability to an IgE antibody specific to Malassezia or even when binding to an IgE antibody occurs, from mast cells or basophils to histamine, etc. It is preferable that the binding ability is such that it does not release the mediator. That is, even when binding to the IgE antibody occurs, it is preferable that the antigenic fragment binds to the IgE antibody at a level substantially lower than that of the purified antigenic protein derived from Malassezia. Thus, the antigenic fragment of the present invention preferably has an IgE activation activity less than that of the purified antigenic protein when used for therapeutic purposes. Therefore, when administered to a patient with malassezia allergy, the allergic response to malassezia of the administered patient can be reduced.

  The antigenicity of the antigenic fragment of the present invention can be evaluated by in vitro tests such as RAST, ELISA, or histamine release in addition to skin tests and intradermal tests on human volunteers.

  An epitope is a basic element or minimal unit recognized by receptors, particularly antibodies (immunoglobulins), histocompatibility antigens and T cell receptors, and an epitope comprises an amino acid sequence essential for receptor recognition. The amino acid sequence of the epitope is imitated, and an amino acid sequence that can reduce the allergic response to malassezia allergen can also be used as the epitope. Using information on the structure of proteins currently available, malassezia allergen peptides can be designed that, when administered in sufficient amounts to patients with malassezia allergy, will alter the patient's allergic response to malassezia. It is also possible to design a reagent or drug that can inhibit the action of inducing an allergic reaction in a malassezia allergen patient. Such agents can be designed to bind to, for example, IgE antibodies against the Malassezia allergen, thereby preventing IgE-allergen binding and subsequent degranulation from mast cells.

  In addition, selection of a peptide containing a T cell epitope is performed by culturing lymphocytes containing T cells obtained from an individual sensitive to a malassezia allergen (an individual having an IgE-mediated immune response) together with an allergen-derived peptide, for example, tritium. It is possible to measure the stimulating activity (juvenile activity) of human T cells by measuring the effect of promoting the uptake of chlorinated thymidine into cells and determining whether T cell proliferation occurs in response to peptides. . Selection of a peptide containing a B cell epitope is performed by selecting an IgE-binding peptide by reacting with an allergen-derived peptide using serum obtained from an individual susceptible to malassezia allergen and measuring the amount of bound IgE. can do.

  Within the scope of the antigenic fragments of the present invention, there are immunologically related fragments of malassezia-derived purified antigenic proteins including malassezia allergens, such as specific antibodies and specific T cells against the fragments. Recognized cross-reactive peptides are also included.

  In order to prepare the antigenic fragment of the present invention, an isolated purified antigenic protein is used as a raw material, enzymatic digestion with a protease such as lysyl endopeptidase or trypsin, cleavage by chemical treatment with cyanogen bromide, and the like. A fragment having antigenicity can be obtained by isolating and purifying the protein by a known method. Moreover, the target antigenic fragment can also be expressed and prepared by using a part of a gene encoding an antigenic protein derived from Malassezia. Furthermore, based on information on the chemical structure of the antigenic fragment, it can also be produced by chemical synthesis using peptide synthesis technology.

  In addition, amino acid substitution, insertion, and deletion can be performed by using genetic engineering techniques and chemical synthesis techniques. For example, the antigenic fragment of the present invention may be modified and derivatized, or at least one amino acid may be deleted, inserted, substituted, or added to enhance stability and / or enhance desired reactivity. it can. Furthermore, it is possible to produce a modified protein or peptide within the scope of the present invention by substituting or adding a D-amino acid, an unnatural amino acid, or an unnatural amino acid analog. Furthermore, the antigenic fragment of the present invention can be chemically modified by binding to polyethylene glycol. Modification of the antigenic fragment also includes reduction, alkylation, acylation, or chemical coupling to a suitable carrier.

  By measuring immune response activity (T cell responsive activation effect, T cell anergy effect, antibody binding effect, etc.) of the antigenic fragment thus obtained, the antigenic fragment is determined and isolated. be able to.

  Next, a method for producing the purified antigenic protein of the present invention will be described. The crude antigen conventionally used is a lyophilized product of the culture filtrate of the culture, or the cultured cells are crushed by an appropriate method to obtain an extract, which is precipitated with ammonium sulfate and freeze-dried. It was purified by a very limited method. The present inventors also tried purification by chromatography, such as gel filtration and ion exchange, which is generally used as a protein purification method using these crude antigens as raw materials. One pure antigenic protein was not successfully isolated.

  The isolated purified antigenic protein derived from Malassezia according to the present invention is obtained by using, for example, a crude antigen prepared from Malassezia cells as a raw material, for example, ion exchange chromatography, chelate resin chromatography, hydrophobic chromatography, gel filtration chromatography, etc. Proteins that bind to IgE antibodies in sera of allergic patients after fractionation by combining the effective separation methods used and then measuring the binding of each fraction to patient serum IgE antibodies by RAST method, immunoblotting, etc. Or a protein that induces immune response activity (T cell responsive activation action, T cell anergy action, etc.) using a patient's lymphocytes can be isolated by various methods.

  That is, first, using a medium containing nutrients suitable for the growth of Malassezia spp. To which Malassezia spp. Such as M. furfur was added with olive oil such as Dixon medium or Tween 40, 60, and the like at a suitable temperature and aeration. The cells are cultured under the above conditions, and the obtained cells are crushed by an appropriate method to obtain an extract. From this extract, the antigenic protein can be purified using separation means including ion exchange chromatography, chelate resin chromatography, and hydrophobic chromatography. That is, ion exchange chromatography, hydrophobic chromatography, gel filtration chromatography, chelate resin chromatography, electrophoresis, or affinity using a resin in which a specific antibody is bound to an antigenic protein derived from Malassezia or an antigenic fragment thereof. It can be isolated as a highly pure protein by combining various known methods for purification of peptides and proteins such as chromatography. The antigenic protein contained in the culture filtrate can also be isolated by the same method.

  Specifically, as shown in the Examples, proteins that cannot be separated in molecular weight can be obtained by ion exchange chromatography using a difference in isoelectric point, hydrophobic chromatography using a difference in hydrophobicity, or chelation with a metal. By combining chelate resin chromatography utilizing the difference in performance and gel filtration chromatography utilizing the difference in molecular weight, it is possible to separate a large number of similar protein assemblies from each other. These facts were unexpected from the knowledge of molecular weight antigenic proteins by conventional immunoblotting of SDS-PAGE. For example, MF-1 and MF-2 are almost the same in terms of molecular weight. The conventional SDS-PAGE cannot be separated. Also, MF-3 and MF-4 cannot be separated in terms of molecular weight.

Furthermore, if a specific example is described about the combination of various isolation | separation means, the following process is illustrated.
Step a: Centrifugation of the cultured cell disruption extract of Malassezia fungus and lyophilization of the supernatant, followed by anion exchange chromatography (for example, DEAE-cellulose column chromatography; Wako Pure Chemical Industries, Ltd.) 0.1 A step of obtaining a fraction eluted with NaCl of M,

Example 19
Application of Diagnosis of Recombinant Malassezia Antigenic Protein 19-a) Method for Measuring Specific IgE Antibody by RAST Method Activation of paper disc by cyanogen bromide and coupling of recombinant malassezia antigenic protein to paper disc This was carried out according to the method of Miyamoto et al. (Allergy, Vol. 22, pages 584-594, 1973). One paper disk with the antigenic protein coupled to a polystyrene tube and 50 μl of patient serum were added and incubated at room temperature for 3 hours. The paper disc was washed three times with physiological saline containing 0.2% Tween 20, and then 50 μl of ¹²⁵ I-labeled anti-human IgE antibody from Pharmacia RAST-RIA kit was added and incubated overnight at room temperature. After washing 3 times again, the radioactivity was measured with a gamma counter. The IgE antibody titer was calculated from a standard curve prepared with the reference reagent of the kit measured simultaneously. Specimens with values higher than the upper limit of the standard curve (> 17.5 PRU / ml) were diluted 10-fold or 100-fold with horse serum and then remeasured to calculate antibody titers.

19-b) Diagnosis with recombinant Malassezia antigenic proteins rMF-1, rMF-2, rMF-4 Atopic Dermatitis (hereinafter abbreviated as AD), allergic asthma (abbreviated as BA). ) And both combined (AD + BA) skin tests with the antigenic protein revealed that 43 out of 57 AD patients (75%) and 108 out of 919 BA patients (12%) ), 47 out of 102 AD + BA patients were positive, showing a very high positive rate in AD patients. In addition, 100%, 59%, and 85% of AD, BA, and AD + BA patients with positive skin tests were positive in IgE antibody measurement by the RAST method.

  Three types of recombination in 76 patients (AD: 30 people, BA: 20 people, AD + BA: 26 people) who are positive in the skin test using the antigenic protein and further RAST positive (score 1 or higher) IgE antibody titers against the antigenic proteins rMF-1, rMF-2, and rMF-4 were measured by the RAST method (RIA method). The IgE antibody titer against the antigenic protein was similarly measured for 12 skin test negative (healthy) individuals. As a result, it was clarified that IgE antibodies against the antigenic protein exist in the patient serum at a very high rate. In particular, the positive rate for rMF-1 and rMF-2 was high. Furthermore, surprisingly, the IgE antibody titer was very high, especially in AD patients, with an average of 100 PRUs for rMF-1 and rMF-2, and some patients exceeding up to 1000 PRUs. In addition, IgE antibodies against any of the recombinant antigenic proteins rMF-1, rMF-2, and rMF-4 were present in the sera of all RAST positive patients against the Malassezia antigen.
