Definitions

  • the present invention relates to a composition
  • a composition comprising an oligonucleotide comprising (a) the sequence N ⁇ - N 2 - G - N 3 - G, wherein Ni represents any nucleotide if N 2 and N 3 are G; N 2 represents any nucleotide if N T and N 3 are G; and N 3 represents any nucleotide if IS and N 2 are G, or (b) the sequence of (a), wherein at least one nucleotide is replaced by a corresponding nucleotide analog or derivative.
  • the present invention also relates to an oligonucleotide having (a) a sequence selected from the group consisting of the sequences of SEQ ID NOs: 1 to 19, or (b) a sequence of (a), wherein at least one nucleotide is replaced by a corresponding nucleotide analog or derivative.
  • a vector comprising an oligonucleotide of the present invention, a host cell comprising the vector of the present invention, a method for the production of the oligonucleotide of the present invention as well as a kit comprising the composition, the oligonucleotide, the vector, and/or the host cell of the present invention are described.
  • the present invention further relates to the use of the composition, and/or the oligonucleotide of the present invention for the production of a pharmaceutical composition for preventing or treating septic shock, inflammation, autoimmune diseases, T H 1 -mediated diseases, bacterial infections, parasitic infections, viral infections, spontaneous abortions, and/or tumors.
  • compositions, and/or the oligonucleotide of the present invention to inhibit activation of antigen-presenting cells, to inhibit the uptake of DNA by a cell, to stimulate natural killer cells, to co- stimulate cytotoxic T-lymphocytes or natural killer cells, to enhance the production of antibodies directed against an antigen, to enhance the uptake of an agent by a cell, and/or to induce proliferation of bone marrow cells in vitro or in vivo.
  • Pathogen challenge by supplying danger stimuli, mobilizes the immune system to respond. Most typically these responses result in the clearance of the challenging pathogen but can also result in overshoot or misdirected responses leading to conditions such as allergy or autoimmune diseases.
  • the immune system can be enhanced, e.g., by vaccination or cytokine therapies, to bolster favorable host responses, or can be suppressed, e.g., by drug intervention or cytokine therapies, to limit unfavorable responses.
  • the functioning of the immune system is based on two distinct recognition systems: innate (myeloid cells, NK cells etc.) or nonclonal host defense and adaptive (T and B cells) or clonal host defense.
  • the innate immune systems receptors recognize conserved molecular structures shared by a large group of pathogens, termed pattern recognition receptors (PRRs) (reviewed in Fearon DT, Locksley RM, Science 1996; 272: 50; Medzhitov R, Janeway CA, Jr., Curr Opin Immunol 1997; 9: 4).
  • PRRs pattern recognition receptors
  • the main difference between PRRs and clonally-distributed antigen receptors of the adaptive system is that their specificities are germline encoded. Thus a parameter imposed on PRRs is recognition of non-self structural patterns.
  • T and B cell receptors through their specificity and diversity, represent the crowning achievement of the vertebrate adaptive immune system they do not distinguish self from non-self.
  • the innate system controls the initiation of the adaptive immune response by regulating the expression of costimulatory activity on antigen presenting cells (APCs), and instructs the adaptive immune system to develop a particular effector response (humoral, cytotoxic, Th1 versus Th2) by releasing effector cytokines.
  • APCs antigen presenting cells
  • the adaptive immune system of vertebrates consists of several interacting components. They can be divided into humoral and cellular branches. Humoral immunity involves antibodies, proteins which are produced and secreted by B cells into the body fluids and which directly recognize an antigen. The cellular system, in contrast, relies on T cells which recognize cells presenting foreign antigens and then responding by proliferation, cytotoxicity or secretion of cytokines. This basic functional division reflects two different strategies of immune defense. Humoral immunity is mainly directed at antigens which are whole proteins, the cellular system responds to antigens which are actively processed and presented by either APC or pathogen infected cells (see, e.g., Paul WE, Cell 1989; 57: 521).
  • Antibody molecules the effectors of humoral immunity, are secreted by B cells in response to antigen receptor stimulation, co-receptor stimulation and cytokines.
  • Antibodies can bind to and inactivate antigen directly (neutralizing antibodies) or activate other cells of the immune system to destroy the antigen depending on isotype; IgM, lgG1 , etc.
  • Isotype class switching in B cells is controlled by the cytokine milieu. Abnormalities in antigen response, co-receptor engagement or cytokine milieu can lead to suboptimal immune responses, tolerance or autoimmunity.
  • the cytokine milieu can push the isotype repertoire to reflect either Th1 (lgG2) or Th2 (lgG1 and IgE) responses which can have beneficial or detrimental effects dependent on the target antigen and challenge source.
  • T cells Cellular immune recognition is mediated by a special class of lymphoid cells, T cells. These cells do not recognize whole antigens but instead they respond to degraded peptide fragments thereof which appear on the surface of the target cell bound to proteins called major histocompatibility complex (MHC) molecules. Essentially all nucleated cells have MHC class I molecules whereas MHC II are restricted to immune cells with special presenting qualities.
  • MHC major histocompatibility complex
  • Proteins produced within the cell are continually degraded to peptides as part of normal cellular metabolism. These fragments are bound to the MHC I molecules and are transported to the cell surface.
  • the cellular immune system is constantly monitoring the spectra of proteins produced by all cells in the body and is poised to eliminate any cells producing foreign antigens or abnormal self-antigens. This is a function of cytolytic T cells.
  • APCs take up antigens from the environment, process them to peptides, and present them in the context of MHC II to helper T cells (Th cells) which respond by producing cytokines. These responses can be divided into Th1 or Th2, as defined by the cytokine pattern. Th1 or Th2 responses are generated dependent on the pathogen challenge and/or the contextual engagement through which the response is generated. Again, Th1 or Th2 biased responses can have either beneficial or detrimental outcomes dependent on the target antigen and the intensity of response.
  • APCs such as dendritic cells and macrophages
  • APCs represent a decisive interface between the innate and adaptive immune system (Banchereau J, Steinman RM, Nature 1998; 392: 245).
  • Signals induced by pattern recognition can be grouped into three categories: first, inflammatory responses including IL-1 , TNF, IL-6, type I IFN and chemokines; second, costimulators of T cell activation including B7.1 (CD80), B7.2 (CD86) and CD40; and third, effector cytokines including IL-10, IL-12, TNF- ⁇ and IFN- ⁇ .
  • APCs need first to be activated thus acquiring the ability to instigate productive T and B cell activation through the above mentioned mediators.
  • TNF Tumor necrosis factor
  • TNF TNF-associated fibrosis .
  • infectious e.g., sepsis syndrome, bacterial meningitis, cerebral malaria, and AIDS
  • autoimmune e.g., rheumatoid arthritis, Crohn's disease, sarcoidosis, multiple sclerosis, Kawasaki syndrome, graft-versus host disease and transplant rejection
  • organ failure e.g., adult respiratory distress syndrome
  • Bacterial DNA can also sensitize mice for the action of LPS and more importantly, bacterial DNA or oligonucleotides (in the following abbreviated by the letters "ODN”) comprising (a) CpG-dinucleotide(s) synergise with LPS in inducing macrophage cytokines in vitro and toxic amounts of TNF- ⁇ in vivo (Sparigan T, Montgomeryhke T, Lipford G, et al., Eur J Immunol 1997; 27: 1671 ; Cowdery JS, Chace JH, Yi AK, Krieg AM, J Immunol 1996; 156: 4570).
  • ODN bacterial DNA or oligonucleotides
  • Th1 response patterns have been demonstrated in a variety of diseases: infectious (e.g., streptococcal induced arthritis, and Lyme arthritis), and autoimmune (e.g., rheumatoid arthritis, chronic inflammatory bowel disease, psoriasis vulgaris, experimental allergic encephalomyelitis (EAE), insulin-dependent diabetes mellitus (IDDM), spontaneous abortion, graft-versus host disease and transplant rejection).
  • Th2 responses are beneficial in various helminth infection and bacterial responses. Thus, in the context of vaccination the ability to direct responses toward Th2 for certain diseases would be beneficial.
  • Vaccination is the process of preparing an animal to respond to an antigen. Vaccination is more complex than immune recognition and involves not only B cells and cytotoxic T cells but other types of lymphoid cells as well. During vaccination, cells, which recognize the antigen (B cells or cytotoxic T cells), are clonally expanded. In addition, the population of ancillary cells (helper T cells which provide co-receptor and cytokine stimulation) specific for the antigen also increase. Vaccination also involves specialized antigen presenting cells, which can process the antigen and display it in a form, which can stimulate one of the two pathways (macrophages and dendritic cells).
  • a foreign antigen is introduced into an animal where it activates specific B cells by binding to surface immunoglobulins. It is also taken up by antigen processing cells, wherein it is degraded, and appears in fragments on the surface of these cells bound to Class II MHC molecules. Peptides bound to class II molecules are capable of stimulating the helper class of T cells. Both helper T cells and activated B cells are required to produce active humoral immunization. Cellular immunity is stimulated by a similar mechanism but entry into the MHC I presentation pathway of antigen presenting cells is typically by intracellular pathogen replication and not achieved by injection of protein antigen only.
  • Standard vaccination schemes nearly always produce a humoral immune response.
  • the humoral system protects a vaccinated individual from subsequent challenge from a pathogen and can prevent the spread of an intracellular infection if the pathogen goes through an extracellular phase during its life cycle; however, it can do relatively little to eliminate intracellular pathogens.
  • Cytotoxic immunity complements the humoraf system by eliminating the infected cells and cancer cells. Thus effective vaccination should activate both types of immunity.
  • cytotoxic T cell response is necessary to remove intracellular pathogens such as viruses as well as malignant cells.
  • pathogens such as viruses as well as malignant cells.
  • a major problem exists in the prior art with respect to the presention of an exogenously administered antigen in adequate concentrations in conjunction with Class I molecules to assure an adequate response.
  • mmune adjuvant refers to compounds which when administered to an individual or tested in vitro, increase the immune response to an antigen.
  • immune adjuvants are known in the art. These include classical adjuvants such as complete Freund's adjuvant or more recently developed compounds like liposomes. Many of these adjuvants, however, have adverse side effects such as local inflammation after administration, or their production is time consuming and/or requires complicated standardized production protocols, in particular when vaccination of humans is envisaged.
