Die Erfindung betrifft Nukleinsäuren, deren Derivate und sequenzspezifische Bindesubstanzen, die die Expression des CD30-Antigens und/oder der ribosomalen S6 Kinase pp90rsk3 hemmen, pharmazeutische Zusammensetzungen, die derartige Nukleinsäuren enthalten, und die Verwendung von derartigen Nukleinsäuren zur Modulation zellulärer Aktivierung, zur Unterdrückung und Verhinderung von Immun- dysregulationen, zur Minderung der Viruslast und zur Beseitigung von CD30+ und/oder pp90rsk3+ Zellen und deren Tumore.The invention relates to nucleic acids, their derivatives and sequence-specific binding substances which inhibit the expression of the CD30 antigen and / or the ribosomal S6 kinase pp90rsk3, pharmaceutical compositions which contain such nucleic acids, and the use of such nucleic acids for modulating cellular activation, for suppressing and Prevention of immune dysregulation, reduction of viral load and elimination of CD30 + and / or pp90rsk3 + cells and their tumors.
Die Zelle antwortet mit einem komplexen Netzwerk der zellulären Aktivierung auf Signale der Umwelt, um eine adäquate Reaktion zu gewährleisten. Der scheinbar unbegrenzten Vielzahl von physikalischen und chemischen Einflüssen steht der Zelle ein vielfältig modulierbares physiologisches Muster spezifischer Antworten durch zelluläre Aktivierung gegenüber. Dysregulationen der zellulären Aktivierung sind jedoch häufig, wobei deren auslösende Umwelteinflüsse oder die deregulierten Sig- nale der Zelle nur selten bekannt sind.The cell responds to environmental signals with a complex network of cellular activation to ensure an adequate response. The seemingly unlimited variety of physical and chemical influences is contrasted by the cell with a versatile, modulatable physiological pattern of specific responses through cellular activation. Dysregulations of cellular activation are common, however, the environmental factors that trigger them or the deregulated signals of the cell are only rarely known.
Das Spektrum der Erkrankungen mit deregulierter zellulärer Aktivierung ist vielfältig und umfaßt Zellen aller Gewebe und Differenzierungen, so z.B. Epithelzellen in Antwort auf bakterielle Toxine, oder Immunzellen in Antwort auf chronische virale Infek- tionen, chronisch-entzündliche und atopische Erkrankungen wie z.B. atopische Der- matitis (Neurodermitis). Einige dieser Erkrankungen sind sehr häufig, so Manifestationen des atopischen Syndroms mit bis zu 15% der Bevölkerung.The spectrum of diseases with deregulated cellular activation is diverse and includes cells from all tissues and differentiations, e.g. Epithelial cells in response to bacterial toxins, or immune cells in response to chronic viral infections, chronic inflammatory and atopic diseases such as e.g. atopic dermatitis (neurodermatitis). Some of these diseases are very common, with manifestations of atopic syndrome affecting up to 15% of the population.
Aufgrund dieser erheblichen Vielfalt von Dysregulationen zellulärer Aktivierung wur- den bereits zahlreiche Verfahren entwickelt, mit denen die pathophysiologischen Regelkreise gezielt und zell-spezifisch durchbrochen werden. Jedoch sind die meisten Verfahren nur mit sehr begrenztem Erfolg anwendbar oder mit erheblichen Nebenwirkungen behaftet, insbesondere bei Verwendung systemisch wirksamer, sup- pressiver Substanzen, wie z.B. bei Immundysregulationen Corticosteriode oder de- ren Derivate, Vitamin D3, Cyclosporin, 15-Desoxyspergualin, Antikörper oder im- munsuppressive Zytokine (Übersicht: Sigal und Dumont, Fundamental Immunology, 3rd. ed., pp903-915, 1993; Ed: W.E. Paul; Raven Press, New York). Allen genannten Immunsuppressiva ist gemeinsam, daß sie nicht selektiv das gesamte Spektrum der Immunzellen supprimieren mit der Folge, daß ein erhöhtes Risiko für Infektionen und maligne Erkrankungen besteht. Die Entwicklung neuer Strategien wird jedoch auch durch die derzeitig noch ungenügenden Kenntnisse der Regelkreise zellulärer Akti- vierung erheblich erschwert.Because of this considerable variety of dysregulations of cellular activation, numerous procedures have already been developed with which the pathophysiological control loops can be broken down in a targeted and cell-specific manner. However, most of the methods can only be used with very limited success or have considerable side effects, especially when using systemically effective suppressive substances, such as, for example, in the case of immune dysregulation corticosteriods or their derivatives, vitamin D3, cyclosporin, 15-deoxyspergualin, antibodies or immunosuppressive cytokines (review: Sigal and Dumont, Fundamental Immunology, 3rd ed., pp903-915, 1993; Ed: WE Paul; Raven Press, New York). All of the above Common to immunosuppressive drugs is that they do not selectively suppress the entire spectrum of immune cells, with the result that there is an increased risk of infections and malignant diseases. However, the development of new strategies is also made considerably more difficult by the currently insufficient knowledge of the control loops of cellular activation.
Das CD30 Antigen ist ein phosphoryliertes 105 -120 kDa Membran-Glykoprotein, das aufgrund von Sequenzhomologien der TNF/NGF Rezeptor Familie zugeordnet wird und von einigen Lymphozyten-Subpopulationen exprimiert wird (Schwab et al., Nature 299, 65-67 (1982); WO93/10232; und Dürkop et al., Cell 68, 421 - 427, 1992). Das CD30 Antigen wird bevorzugt, jedoch nicht ausschließlich, auf Th2 T- Zellen gefunden, insbesondere bei einer Subpopulation (15-20%) aktivierter CD45RO+ "memory" T-Zellen, von denen 85% der Zellen das CD4 Antigen koex- primieren. Zellen mit persistierenden viralen Infektionen und Zellen zahlreicher virus- assoziierter Tumore exprimieren ebenfalls das CD30 Antigen. Auch findet man eine hohe CD30 Expression bei den malignen Zellen des Hodgkin-Lymphoms. den sog. Reed-Stemberg Zellen, bei Zellen des anaplastischen Großzell-Lymphoms, und auf Zellen embryonaler und mesenchymaler Keimzell-Tumoren (Suster et al., Hum. Pathol. 29, 737-742, 1998).The CD30 antigen is a phosphorylated 105-120 kDa membrane glycoprotein that is assigned to the TNF / NGF receptor family based on sequence homologies and is expressed by some lymphocyte subpopulations (Schwab et al., Nature 299, 65-67 (1982); WO93 / 10232; and Dürkop et al., Cell 68, 421-427, 1992). The CD30 antigen is preferred, but not exclusively, found on Th2 T cells, especially in a subpopulation (15-20%) of activated CD45RO + "memory" T cells, of which 85% of the cells coexpress the CD4 antigen. Cells with persistent viral infections and cells from numerous virus-associated tumors also express the CD30 antigen. There is also high CD30 expression in the malignant cells of Hodgkin's lymphoma. the so-called Reed-Stemberg cells, in cells of anaplastic large cell lymphoma, and on cells of embryonic and mesenchymal germ cell tumors (Suster et al., Hum. Pathol. 29, 737-742, 1998).
Die Funktion des CD30 Moleküls in normalen Immunzellen ist bisher nicht im Detail geklärt (Romagnani, The Immunologist 6, 137 - 141 , 1998). CD30 Kreuzvernetzung auf der Zelloberfläche führt zu einer verwirrenden Vielzahl von zellulären Funktionen, z.B. zu einer Erhöhung der T-Zell Proliferation (Smith et al., Cell 73, 1349-1360, 1993), zur Induktion des Transkriptionsfaktors NFKB (McDonald et al., Europ. J. Im- munol. 25, 2870-2876, 1995), zur Induktion der HIV Genexpression in HIV infizierten T-Zellen (Biswas et al., Immunity 2, 587-596, 1995; Maggi et al., Immunity 3, 251- 255, 1995), zur Erhöhung des intrazellulären Calciums (Ellis et al., J. Immunol. 151 , 2380-2389, 1993) und zur Einleitung des Zelltods (Gruss et al., Blood 83, 2045- 2056, 1994).The function of the CD30 molecule in normal immune cells has not yet been elucidated in detail (Romagnani, The Immunologist 6, 137-141, 1998). CD30 cross-linking on the cell surface leads to a confusing variety of cellular functions, e.g. to increase T cell proliferation (Smith et al., Cell 73, 1349-1360, 1993), to induce the transcription factor NFKB (McDonald et al., Europ. J. Immunol. 25, 2870-2876, 1995 ), to induce HIV gene expression in HIV-infected T cells (Biswas et al., Immunity 2, 587-596, 1995; Maggi et al., Immunity 3, 251-255, 1995), to increase the intracellular calcium (Ellis et al., J. Immunol. 151, 2380-2389, 1993) and to induce cell death (Gruss et al., Blood 83, 2045-2056, 1994).
Die ribosomalen S6 Kinasen (pp90rsk1 , rsk2, rsk3) bilden eine Familie von Mitogen- aktivierten Protein Kinasen. Sie sind ubiquitär in Zellen verschiedener Gewebe auf unterschiedlichem Niveau exprimiert. Die pp90rsk1 Kinase liegt funktioneil stromab- wärts der MAP Kinase in dem Ras-Raf-MEK-MAP Kinase Signalweg (Sturgill et al., Nature 334, 715-718, 1988; Blenis, Proc. Natl. Acad. Sei. USA 90, 5889-5892, 1993). Sie phosphoryliert u.a. den Faktor lκBα und stimuliert dessen Abbau (Ghoda et al., J. Biol. Chem. 272, 21281-21288, 1997). Die pp90rsk3 Kinase ist im Gegensatz zur pp90rsk1 Kinase bisher wenig untersucht worden. Im Gegensatz zu pp90rsk1 stimulieren Wachstumsfaktoren, nicht aber ERK2/MAP Kinase die pp90rsk3 Autophosphorylierung. Nach Stimulierung der Zellen wird eine nukleare Translokation des pp90rsk3 Proteins beobachtet, was die Vermutung nahelegt, daß pp90rsk3 bisher nicht identifizierte nukleare Proteine phosphoryliert (Zhao et al., Mol. Cell. Biol. 15, 4353 - 4363, 1995).The ribosomal S6 kinases (pp90rsk1, rsk2, rsk3) form a family of mitogen-activated protein kinases. They are ubiquitously expressed in cells of different tissues at different levels. The pp90rsk1 kinase is functionally downstream of the MAP kinase in the Ras-Raf-MEK-MAP kinase signaling path (Sturgill et al., Nature 334, 715-718, 1988; Blenis, Proc. Natl. Acad. Sci. USA 90, 5889-5892, 1993). It phosphorylates the factor lκBα and stimulates its breakdown (Ghoda et al., J. Biol. Chem. 272, 21281-21288, 1997). In contrast to the pp90rsk1 kinase, the pp90rsk3 kinase has so far been little investigated. In contrast to pp90rsk1, growth factors, but not ERK2 / MAP kinase, stimulate pp90rsk3 autophosphorylation. After stimulation of the cells, a nuclear translocation of the pp90rsk3 protein is observed, which suggests that pp90rsk3 phosphorylates previously unidentified nuclear proteins (Zhao et al., Mol. Cell. Biol. 15, 4353-4363, 1995).
Die Verwendung von sense und anti-sense orientierten Nukleinsäuren zur spezifi- sehen Hemmung der Gen-Expression ist ein dem Fachmann bekanntes Verfahren. Rationale Strategien zur Generierung derartig wirksamer Moleküle auf der Grundlage bekannter Gesetzmäßigkeiten bestehen jedoch z.Zt. nicht (Branch: "A good antisense molecule is hard to find", TIBS 23, 45-50, 1998). Anders ausgedrückt, ausgehend von einer bekannten DNA oder cDNA können Nukleinsäuren mit einer derartigen funktionellen Eigenschaft nicht zwingend abgeleitet werden.The use of sense and anti-sense oriented nucleic acids for the specific inhibition of gene expression is a method known to the person skilled in the art. However, there are currently rational strategies for generating such effective molecules based on known laws. not (Branch: "A good antisense molecule is hard to find", TIBS 23, 45-50, 1998). In other words, starting from a known DNA or cDNA, nucleic acids with such a functional property cannot necessarily be derived.
Bei der Vielfalt möglicher Dysregulationen zellulärer Aktivierung wird ein Mittel zur spezifischen funktioneilen Suppression der Zellen gesucht, mit dessen Hilfe die pathophysiologischen Regelkreise der Autostimulation durchbrochen werden können.Given the variety of possible dysregulations of cellular activation, a means for specific functional suppression of the cells is sought, with the help of which the pathophysiological control loops of autostimulation can be broken.
Überraschenderweise wurde gefunden, daß bestimmte Nukleinsäuren (Oligonukleotide) in vivo an die CD30 und/oder die für die ribosomale S6 Kinase pp90rsk3 spezifische RNA, Gen- oder Promoter-DNA binden und eine gezielte funk- tionelle Suppression der Expression des CD30 Antigens und/oder der ribosomalen S6 Kinase pp90rsk3 (nachfolgend kurz "rsk3") bewirken. Weiterhin wurde gefunden, daß mit Hilfe dieser Nukleinsäuren CD30 und/oder rsk3 exprimierende Zellen eliminiert werden können. Im einzelnen wird durch die genannten Nukleinsäuren eine selektive funktioneile Suppression der Aktivierung von CD30+ und/oder pp90rsk3+ (nachfolgend "rsk3+") Zellen erzielt, die Aktivierung dieser Zellen verhindert, die de- regulierte Produktion zellulärer Substanzen revertiert, die aktivierungsinduzierte Proliferation unterdrückt, die Virusproduktion supprimiert und diese Zelle dem Zelltod zugeführt ohne erkennbare Schädigung anderer Zellen oder Gewebe.Surprisingly, it was found that certain nucleic acids (oligonucleotides) bind in vivo to the CD30 and / or the RNA, gene or promoter DNA specific for the ribosomal S6 kinase pp90rsk3 and a targeted functional suppression of the expression of the CD30 antigen and / or the ribosomal S6 kinase pp90rsk3 (hereinafter referred to as "rsk3"). Furthermore, it was found that CD30 and / or rsk3 expressing cells can be eliminated with the aid of these nucleic acids. In particular, a selective functional suppression of the activation of CD30 + and / or pp90rsk3 + (hereinafter "rsk3 +") cells is achieved by the nucleic acids mentioned, the activation of these cells is prevented, the regulated production of cellular substances is reversed, the activation-induced proliferation is suppressed, the virus production suppressed and this cell led to cell death without recognizable damage to other cells or tissues.

Such modifications are described in detail below. "Sequence-specific binding substances" according to the present invention are understood to mean nucleic acids and other substances which are characterized in that they bind selectively to defined DNA and / or RNA sequences. These also include those nucleic acid derivatives in which two or more modifications have been made and therefore can no longer be correctly referred to as nucleic acids in the narrower sense.

Die Oligonukleotide können lineare unmodifizierte DNA oder RNA Moleküle oder nach bekannten Verfahren modifizierte DNA oder RNA Molekül sein (Agrawal und lyer, Pharmakol. Ther. 76, 151 - 160, 1997). Beispiele sind zyklische Oligonukleotide (Kool, J. Am. Chem. Soc. 113, 6265-6266, 1991), Phosphorothioat Derivate, 2' O- methyl RNA, morpholino-modifizierte Oligomere, Me.thylphosphonate, PNA ("peptide nucleic acids"), N3'->P5' Phosphoramidate, oder sog. "clamp oligonucleotides" (Übersicht: Cohen, Adv. Pharmakol. 25, 319-339, 1993, Matteucci, Ciba Found. Symp. 209, 5-14, 1997, Sun et al., Curr. Opin. Stuct. Biol. 6, 327 - 333, 1996; Helene et al., Ciba Found. Symp. 209, 94 -102, 1997). Die Oligonukleotide können auch von viralen oder nicht-viralen Expressionsvektoren transkribiert werden, d. h., daß die erfindungsgemäßen Nukleinsäuren auch als Bestandteile derartiger Vektoren vorliegen können.The oligonucleotides can be linear unmodified DNA or RNA molecules or DNA or RNA molecules modified by known methods (Agrawal and Iyer, Pharmakol. Ther. 76, 151-160, 1997). Examples are cyclic oligonucleotides (Kool, J. Am. Chem. Soc. 113, 6265-6266, 1991), phosphorothioate derivatives, 2 ' O-methyl RNA, morpholino-modified oligomers, methyl phosphonates, PNA ("peptide nucleic acids" ), N3 ' -> P5 ' phosphoramidates, or so-called "clamp oligonucleotides" (overview: Cohen, Adv. Pharmakol. 25, 319-339, 1993, Matteucci, Ciba Found. Symp. 209, 5-14, 1997, Sun. et al., Curr. Opin. Stuct. Biol. 6, 327-333, 1996; Helene et al., Ciba Found. Symp. 209, 94-102, 1997). The oligonucleotides can also be transcribed from viral or non-viral expression vectors, ie the nucleic acids according to the invention can also be present as components of such vectors.
Eine weitere Ausführungsform der vorliegenden Erfindung besteht darin, daß die erfindungsgemäßen Nukleinsäuren als Bestandteile von Ribozymen oder anderen enzymatisch aktiven Nukleinsäuren mit spezifischer Bindung an die CD30 und/oder rsk3 mRNA oder DNA vorliegen. Bevorzugt sind Ribozyme, deren spezifische Binderegion eines der in Tabelle 1 oder Tabelle 2 genannten Nukleotidsequenzen enthält. Die erfindungsgemäßen Nukleinsäuren, Oligonukleotide und Ribozyme weisen dabei jedoch nicht die exakte Suequenz der in SEQ ID NO:1 und NO:3 gezeigten CD30 und rsk3 mRNAs auf.Another embodiment of the present invention is that the nucleic acids according to the invention are present as components of ribozymes or other enzymatically active nucleic acids with specific binding to the CD30 and / or rsk3 mRNA or DNA. Ribozymes are preferred whose specific binding region contains one of the nucleotide sequences mentioned in Table 1 or Table 2. However, the nucleic acids, oligonucleotides and ribozymes according to the invention do not have the exact sequence of the CD30 and rsk3 mRNAs shown in SEQ ID NO: 1 and NO: 3.
Die pharmazeutische Zusammensetzung gemäß der vorliegenden Erfindung kann dabei neben einer oder mehreren der erfindungsgemäßen Nukleinsäuren noch einen pharmazeutisch akzeptablen Träger und/oder pharmazeutische Hilfsstoffe enthalten. Pharmazeutische Träger für Nukleinsäuren sind bevorzugt Lipide beispielsweise kationische oder anionische Liposomen oder Lipide wie DOPE (Dioleoyl-phosphatidyl- ethanolamin), DC-Chol (3ß[N-(N',N'-Dimethylaminoethan)carbamoyl]-Cholesterol oder DOTAP (1 ,2-Dioloyloxy-3-(Trimethylammonio)propan). Lipid-DNA Partikel eig- nen sich außerdem nach Kopplung mit einem geeigneten Liganden für den gewebespezifischen Nukleinsäuretransfer. Auch können virale, beispielsweise adenovirale, Partikel oder artifizielle Partikel genutzt werden, die Nukleinsäuren binden (komplexieren) und den DNA-Transfer in die Zellen erleichtern. Die erfindungsgemäßen Nukleinsäuren können auch ohne pharmakologische Träger übertragen werden, z.B. durch Nukleinsäurepräzipitation, Elektroporation, Injektion, Partikelbombardierung ("gene gun"). 8In addition to one or more of the nucleic acids according to the invention, the pharmaceutical composition according to the present invention can also contain a pharmaceutically acceptable carrier and / or pharmaceutical adjuvants. Pharmaceutical carriers for nucleic acids are preferably lipids, for example cationic or anionic liposomes or lipids such as DOPE (dioleoylphosphatidylethanolamine), DC-chol (3β [N- (N ' , N ' -dimethylaminoethane) carbamoyl] cholesterol or DOTAP (1, 2-dioloyloxy-3- (trimethylammonio) propane).

In Experimenten konnte eine Vielzahl pharmakologischer Effekte für die erfindungsgemäßen Nukleinsäuren gezeigt werden:A large number of pharmacological effects for the nucleic acids according to the invention could be shown in experiments:
1. Es wurde gefunden, daß in Gegenwart der erfindungsgemäßen Nukleinsäuren CD30+ und/oder rsk3+ Zellen ihre spezifischen zellulären Funktionen und Syntheseleistungen, die mit der zellulären Aktivierung einhergehen (z.B. die Zytokinsyn- these), einstellen oder modulieren (Beispiel 2), CD30-rsk3- Zellen werden in ihrer Funktion nicht beeinträchtigt.1. It has been found that in the presence of the nucleic acids CD30 + and / or rsk3 + cells according to the invention adjust or modulate their specific cellular functions and synthesis functions which are associated with cellular activation (eg cytokine synthesis) (Example 2), CD30-rsk3 - Cells are not impaired in their function.
2. Die induzierte und konstitutive zelluläre Aktivierung, beispielhaft gekennzeichnet durch NFKB Aktivierung, wird in Gegenwart der erfindungsgemäßen Nukleinsäuren spezifisch supprimiert (Beispiel 3). Dabei ist es unerheblich, ob die zelluläre Aktivierung nach chemischen oder physikalischen Einwirkungen erfolgt ist oder nach Kontakt mit Bakterien oder Viren oder deren Bestandteile oder auf der Grundlage unbe- kannter Stimuli erfolgt. In Folge der Applikation der erfindungsgemäßen Nukleinsäuren verändert die Zelle ihre Funktionen dahingehend, daß die zelltypspezifische zelluläre Aktivierung supprimiert wird, was z.B. durch Suppression der Expression von endothelial cell adhesion molecule oder A20, mitochondriale Dehydrogenase (oder Mangansuperoxid Dismutase in CD30+ Zellen gekennzeichnet ist. Eine Verwendung der erfindungsgemäßen Nukleinsäuren ist daher die funktionelle Suppression zellulärer Aktivierung selektiv von CD30+ und/oder rsk3+ Zellen, ohne die funktionelle Aktivität anderer Zellen unmittelbar zu verändern. CD30+ und/oder rsk3+ (Tumor)zellen können in Gegenwart der erfindungsgemäßen Nukleinsäuren in einen Status überführt werden, der die Zellen empfindlich macht für Chemotherapeutika-, Zytokin- oder strahleninduzierten Zelltod.2. The induced and constitutive cellular activation, characterized for example by NFKB activation, is specifically suppressed in the presence of the nucleic acids according to the invention (example 3). It is irrelevant whether the cellular activation took place after chemical or physical effects or after contact with bacteria or viruses or their components or on the basis of unknown stimuli. As a result of the application of the nucleic acids according to the invention, the cell changes its functions in such a way that the cell type-specific cellular activation is suppressed, which e.g. characterized by suppression of the expression of endothelial cell adhesion molecule or A20, mitochondrial dehydrogenase (or manganese superoxide dismutase in CD30 + cells. One use of the nucleic acids according to the invention is therefore the functional suppression of cellular activation of CD30 + and / or rsk3 + cells without the functional activity of others In the presence of the nucleic acids according to the invention, CD30 + and / or rsk3 + (tumor) cells can be converted into a status which makes the cells sensitive to chemotherapeutic, cytokine or radiation-induced cell death.
3. Es wurde gefunden, daß bei bestehender Immundysregulation das physiologische Th1/Th2 T-Zell Gleichgewicht durch eine spezifische funktionelle Suppression von CD30+ und/oder rsk3+ Zellen in Gegenwart der erfindungsgemäßen Nukleinsäuren wieder hergestellt wird, was gekennzeichnet ist durch die Änderung der Sekretion bestimmter Zytokine und anderer Effektorsubstanzen (Beispiel 2).3. It was found that with existing immune dysregulation, the physiological Th1 / Th2 T cell balance is restored by a specific functional suppression of CD30 + and / or rsk3 + cells in the presence of the nucleic acids according to the invention, which is characterized by the change in the secretion of certain cytokines and other effector substances (example 2).
4. Es zeigte sich weiterhin, daß selektiv CD30+ und/oder rsk3+ Zellen in Gegenwart der erfindungsgemäßen Oligonukleotide ihre Proliferation einstellen (Beispiel 4) und dem Zelltod unterliegen (Beispiel 5). Eine Verwendung der erfindungsgemäßen Nukleinsäuren ist daher die Suppression und die Verhinderung des Wachstums von malignen und benignen CD30+ und/oder pp90rsk3+ Zellen, von Tumoren und von Gewebe-Infiltrationen, Mikroabsiedlungen und Metastasierungen dieser Zellen und die Verhinderung der Rezidivierung von Tumoren dieser Zellen. Beispiele für derartige Tumore sind das Hodgkin-Lymphom, das anaplastische Großzell-Lymphom, T- Zell-Leukämie, Keimzelltumore und embryonale Karzinome. Eine weitere Verwen- düng ist beispielsweise die Elimination von CD30+ und/oder rsk3+ Zellen, beispielsweise aus Transplantaten, Knochenmarksbiopsien, etc. beim Purging oder aus dem Blut (Beispiel 7), beispielsweise von Atopikem oder Pollenallergikern.4. It was also shown that selectively CD30 + and / or rsk3 + cells stop their proliferation in the presence of the oligonucleotides according to the invention (Example 4) and are subject to cell death (Example 5). One use of the nucleic acids according to the invention is therefore the suppression and the prevention of the growth of malignant and benign CD30 + and / or pp90rsk3 + cells, of tumors and of Tissue infiltration, micro-colonization and metastasis of these cells and the prevention of recurrence of tumors of these cells. Examples of such tumors are Hodgkin's lymphoma, anaplastic large cell lymphoma, T-cell leukemia, germ cell tumors and embryonic carcinomas. Another use is, for example, the elimination of CD30 + and / or rsk3 + cells, for example from transplants, bone marrow biopsies, etc. during purging or from the blood (Example 7), for example from atopics or pollen allergy sufferers.
5. Es wurde gefunden, daß Blutlymphozyten in Gegenwart der erfindungsgemäßen Nukleinsäuren nicht zur Entwicklung von CD30+ und/oder pp90rsk3+ Zellen stimuliert werden können (Beispiel 6). Auch kann keine Hyperstimulation der Zellen induziert werden. Es wurde gezeigt, daß eine anhaltende, hohe Sekretion von IL-10, wie sie nach wiederholter Stimulation von Lymphozyten mit Antigen zu beobachten ist, in Gegenwart der erfindungsgemäßen Nukleinsäuren unterdrückt wird, während die von IFN-gamma unbeeeinflußt bleibt (Beispiel 2). Die erfindungsgemäßen Nukleinsäuren können daher zur spezifischen Prävention einer Immunhyperstimulation, die mit der Entwicklung von CD30+ und/oder rsk3+ Zellen einhergeht, verwendet werden, während andere Immunstimulationen unbeeinflußt bleiben. Diese Verwendungsform ist außerordentlich vielfältig, beispielhaft sind genannt die Verwendung zur Verhinderung der Akkumulation von CD30+ Lymphozyten im Blut bei Atσpikern oder bei Patienten mit Pollenallergie und damit verbunden eine Unterdrückung der akuten Symptomatik der Erkrankung.5. It was found that blood lymphocytes in the presence of the nucleic acids according to the invention cannot be stimulated to develop CD30 + and / or pp90rsk3 + cells (Example 6). Hyperstimulation of the cells cannot be induced either. It has been shown that a sustained, high secretion of IL-10, as can be observed after repeated stimulation of lymphocytes with antigen, is suppressed in the presence of the nucleic acids according to the invention, while that of IFN-gamma remains unaffected (Example 2). The nucleic acids according to the invention can therefore be used for the specific prevention of an immune hyperstimulation which is associated with the development of CD30 + and / or rsk3 + cells, while other immune stimulations remain unaffected. This form of use is extraordinarily diverse, examples being the use for preventing the accumulation of CD30 + lymphocytes in the blood in atσpikers or in patients with pollen allergy and associated suppression of the acute symptoms of the disease.
6. Es wurde gefunden, daß in Gegenwart der erfindungsgemäßen Nukleinsäuren die Produktion zahlreicher Viren in virusinfizierten Zellen supprimiert ist. Bevorzugt ist diese Anwendungsform bei Zellen mit persistierender Virusinfektion zur Unterdrük- kung der Virusproduktion und der Verringerung der "Viruslast" (virus load) der Zellen. Das Anwendungsspektrum dieser Ausführungsform der Erfindung ist sehr vielfältig, da zahlreiche persistierende Virusinfektionen mit permanenter oder induzierbarer Produktion infektiöser Viruspartikel bekannt sind. Beispielhaft sind hier genannt die Verwendung der erfindungsgemäßen Nukleinsäuren zur Unterdrückung der Produktion von Human Immundefizienz Virus (HIV), Epstein-Barr Virus, von Hepatitis Viren, Human T-Leukämie-Viren I und II, sowie die Anwendung zur Verringerung der Viruslast in infizierten Zellen und zur Minderung der Neuinfektionen mit dem Ziel der Reduktion der Zahl infizierter Zellen. Beispielsweise wurde durch Bestimmung der reversen Transkriptase gefunden, daß im zellfreien Kulturüberstand von Blut-Lym- phozyten HlV-infizierter Spender in Gegenwart der erfindungsgemäßen Nukleinsäu- 106. It has been found that the production of numerous viruses in virus-infected cells is suppressed in the presence of the nucleic acids according to the invention. This form of application is preferred for cells with persistent virus infection to suppress virus production and to reduce the "virus load" of the cells. The range of applications of this embodiment of the invention is very diverse, since numerous persistent virus infections with permanent or inducible production of infectious virus particles are known. Examples are the use of the nucleic acids according to the invention for suppressing the production of human immunodeficiency virus (HIV), Epstein-Barr virus, hepatitis viruses, human T-leukemia viruses I and II, and the use for reducing the viral load in infected cells and to reduce new infections with the aim of reducing the number of infected cells. For example, it was found by determination of the reverse transcriptase that in the cell-free culture supernatant of blood lymphocytes HIV-infected donors in the presence of the nucleic acids according to the invention 10
ren, bevorzugt die in Tabelle 1 und Tabelle 2 genannten Nukleinsäuren, ein um den Faktor 10-100 verminderter Titer von HI-Viren vorliegt im Vergleich zur Inkubation ohne Nukleinsäuren oder der "non-sense" Nukleinsäure. Dieses demonstriert, daß die Freisetzung von HI-Viren (Virusproduktion) einer infizierten Lymphozyten-Popu- Iation in Gegenwart der erfindungsgemäßen Nukleinsäuren supprimiert ist. Weiterhin wurde mit Hilfe der RT-PCR gefunden, daß die Kopienzahl der HI-Virus Genome in dieser Kultur um den Faktor 10-100 reduziert ist, was demonstriert, daß die „Viruslast" (virus load) dieser Lymphozyten-Population supprimiert ist.ren, preferably the nucleic acids mentioned in Table 1 and Table 2, there is a titer of HI viruses reduced by a factor of 10-100 compared to incubation without nucleic acids or the "non-sense" nucleic acid. This demonstrates that the release of HI viruses (virus production) from an infected lymphocyte population is suppressed in the presence of the nucleic acids according to the invention. Furthermore, it was found with the aid of RT-PCR that the copy number of the HI virus genomes in this culture is reduced by a factor of 10-100, which demonstrates that the “virus load” of this lymphocyte population is suppressed.
7. Es wurde weiterhin gefunden, daß rsk3 spezifische Oligonukleotide die Pseudo- monas aeruginosa-induzierte Mucin-Überproduktion, bevorzugt von MUC2, in Epithelzellen hemmen. Bevorzugte Anwendungen der erfindungsgemäßen Nukleinsäuren sind bei Erkrankungen mit Überproduktion von Muchen durch respiratorische Epithelzellen, z.B. bei Patienten mit zystischer Fibröse.7. It was also found that rsk3-specific oligonucleotides inhibit the pseudomonas aeruginosa-induced mucin overproduction, preferably of MUC2, in epithelial cells. Preferred applications of the nucleic acids according to the invention are in diseases with overproduction of musk by respiratory epithelial cells, e.g. in patients with cystic fibrosis.

Die aktivierte, DNA-bindende Form von p65 und p50 NFKB wird in Gegenwart des Oligonukleotids SEQ ID NO:5 und des Oligonukleotids SEQ ID NO: 10 supprimiert.The activated, DNA-binding form of p65 and p50 NFKB is suppressed in the presence of the oligonucleotide SEQ ID NO: 5 and the oligonucleotide SEQ ID NO: 10.
Da die aktivierte Form von NFKB für wesentliche Schritte der zellulären Aktivierung benötigt wird, demonstriert dieses Ergebnis, daß in Gegenwart der Oligonukleotide SEQ ID NO:5 und NO: 10 die zelluläre Aktivierung in einem zentralen Schritt unterbrochen wurde.Since the activated form of NFKB is required for essential steps of cellular activation, this result demonstrates that in the presence of the oligonucleotides SEQ ID NO: 5 and NO: 10, the cellular activation was interrupted in a central step.

Eines der frühesten erkennbaren Merkmale apoptotischer Zellen ist die Präsentation von Phosphatidylserin an der Zelloberfläche, wodurch eine hohe Bindungsaffinität zu Annexin V entsteht. Zum Nachweis apoptotischer Zellen wurde am Tag 3 die Anzahl Annexin V bindender Zellen durch Inkubation mit FITC-konjugiertem Annexin V (Coulter-Immunotech, Cat.
