Definitions
- the present invention is related to methods for inducing an anti-tumor immune response by immunizing a mammal with a composition comprising a tumor cell which expresses a Nod-like receptor (NLR) and/or a Toll-like receptor (TLR) ligand-tumor associated antigen (TAA) fusion protein or with an activated DC which has internalized a tumor cell which expresses an NLR- and/or TLR ligand-TAA fusion protein.
- NLR Nod-like receptor
- TLR Toll-like receptor
- TAA ligand-tumor associated antigen
- Multicellular organisms have developed two general systems of immunity to infectious agents.
- the two systems are innate or natural immunity (usually referred to as “innate immunity”) and adaptive (acquired) or specific immunity.
- innate immunity innate or natural immunity
- adaptive (acquired) or specific immunity The major difference between the two systems is the mechanism by which they recognize infectious agents.
- Recent studies have demonstrated that the innate immune system plays a crucial role in the control of initiation of the adaptive immune response and in the induction of appropriate cell effector responses (Fearon et al. Science 1996;272:50-53 and Medzhitov et al. Cell 1997;91:295-298).
- the innate immune system uses a set of germline-encoded receptors for the recognition of conserved molecular patterns present in microorganisms. These molecular patterns occur in certain constituents of microorganisms including: lipopolysaccharides, peptidoglycans, lipoteichoic acids, phosphatidyl cholines, bacterial proteins (e.g., flagellin), including lipoproteins, bacterial DNAs, viral single and double-stranded RNAs, unmethylated CpG-DNAs, mannans, and a variety of other bacterial and fungal cell wall components. Such molecular patterns can also occur in other molecules such as plant alkaloids.
- PAMPs Pathogen Associated Molecular Patterns
- PRRs Pattern Recognition Receptors
- TLR3, collectins Some of these receptors recognize PAMPs directly (e.g., TLR3, collectins), while others (e.g., complement receptors) recognize the products generated by PAMP recognition.
- Cellular PRRs are expressed on effector cells of the innate immune system, including cells that function as professional antigen-presenting cells (APC) in adaptive immunity.
- effector cells include, but are not limited to, macrophages, dendritic cells, B lymphocytes, and surface epithelia.
- This expression profile allows PRRs to directly induce innate effector mechanisms, and also to alert the host organism to the presence of infectious agents by inducing the expression of a set of endogenous signals, such as inflammatory cytokines and chemokines. This latter function allows efficient mobilization of effector forces to combat the invaders.
- PRRs include Nod-like receptors (NLRs) and Toll-like receptors (TLRs).
- NLRs are cytoplasmic proteins that may have a variety of functions in regulation of inflammatory and apoptotic responses. NLRs are composed of conserved “modules” including a central nucleotide-binding oligomerization domain and a series of tandem leucine-rich repeats. NLRs are encoded by genes from a large gene family present in many different animal species; there are more than 20 NLR genes in humans. Many are thought to serve as PRRs which sense microbial products in the cytoplasm of cells, although some members have different functions. The ligands'are currently known for the NLRs, NLRC1 (NOD1) and NLRC2 (NOD2).
- NLRC1 recognizes a molecule called Meso-diaminopimelic acid (meso-DAP), which is a peptidoglycan constituent of only Gram negative bacteria.
- NLRC2 proteins recognize intracellular MDP (muramyl dipeptide), which is a peptidoglycan constituent of both Gram positive and Gram negative bacteria. These proteins transduce signals in the pathway of NF- ⁇ B and MAP kinases.
- NLRC4 has also been shown to activate caspase-1 in response to bacteria. Further, anthrax toxin activates NLRP1 (previously called NALP1), and Staphylococcus aureus toxins such as alpha-hemolysin (GenBank Accession No.
- AAA26598 (SEQ ID NO: 1) activate NLRP3.
- Other NLRs such as NAIP have also been shown to activate caspase-1 in response to Salmonella and Legionella .

Annu Rev Biochem. 2005, Volume 74:355-83; Strober et al., Signalling pathways and molecular interactions of NOD1 and NOD2. Nat Rev Immunol. 2006, Volume 6(1):9-20; Chen G, Shaw M H, Kim Y G, Nu ⁇ ez G. Annu Rev Pathol. 2009, 4:365-98; Martinon F, Mayor A, Tschopp J. Annu Rev Immunol. 2009;27:229-65].
- TLRs Toll-like receptors
- TLR4 can induce the secretion of tumor necrosis factor (TNF) and of the interleukins IL-1 and IL-6 as part of an antibacterial response, and can induce the secretion of the interferons INF ⁇ and INF ⁇ as part of an anti viral response.
- TNF tumor necrosis factor
- TLR signaling consists of at least two distinct pathways: a MyD88-dependent pathway that leads to the production of inflammatory cytokines, and a MyD88-independent pathway associated with the stimulation of IFN- ⁇ and the maturation of dendritic cells.
- the MyD88-dependent pathway is common to all TLRs, except TLR3 [Adachi O. et al., 1998. Targeted disruption of the MyD88 gene results in loss of IL-1- and IL-18-mediated function. Immunity. 9(1):143-50.].
- TLRs Upon activation by microbial antigens, TLRs induce the recruitment of MyD88 via its T1R domain which in turn recruits IRAK1 and IRAK4 and leads to complex downstream signaling cascades leading to the phosphorylation of I ⁇ B and the subsequent nuclear localization of NF- ⁇ B. Activation of NF- ⁇ B triggers the production of pro-inflammatory cytokines such as TNF- ⁇ , IL-1 and IL-12.
- TLRs have been shown to recognize PAMPs such as the bacterial products LPS (Schwandner et al. J. Biol. Chem. 1999;274:17406-9 and Hoshino et al. J. Immunol 1999;162:3749-3752), lipoteichoic acid (Schwandner et al. J. Biol. Chem. 1999;274:17406-9), peptidoglycan (Yoshimura et al. J. Immunol. 1999;163:1-5), lipoprotein (Aliprantis et al. Science 1999;285:736-9), CpG-DNA (Hemmi et al.
- TLR2 is essential for the recognition of a variety of PAMPs, including bacterial lipoproteins, peptidoglycan, and lipoteichoic acids.
- TLR3 is implicated in virus-derived double-stranded RNA.
- TLR4 is predominantly activated by lipopolysaccharide.
- TLR9 is required for response to unmethylated CpG DNA. Recently, TLR7 and TLR8 have been shown to recognize single stranded RNA molecules (Hornung V. et al. Handb Exp Pharmacol. 2008;(183):71-86), and small synthetic antiviral molecules (Jurk M. et al. Nat Immunol 2002;3:499). TLR11 detects profilin-like protein (PLP). Furthermore, TLR5 detects bacterial flagellin.
- Flagellin is a protein expressed by a variety of flagellated bacteria ( Salmonela typhimurium for example) as well as non-flagellated bacteria (such as Escherichia coli ). Sensing of flagellin by cells of the innate immune system (dendritic cells, macrophages, etc) is mediated by the Toll-like receptor 5 (TLR5) as well as by Nod-like receptors (NLRs) Ipaf and Naip5 (Franchi et al (2006) Nat Immunol 7(6):576-582; Miao et al (2006) Nat Immunol 7(6):569-575; and Ren et al (2006) PLoS Pathog 2(3):e18).

- Bacillus anthracis is the bacterium that causes anthrax.
- the bacterium secretes a toxin called anthrax lethal toxin, which is the major cause of pathogenesis, and is composed of a protective antigen and a lethal factor (Stephen, J. Anthrax toxin. 1981. Pharmacol. Ther. 12, 501-513).
- lethal factor component of anthrax toxin enters the cytosol of macrophages and other cell types, and is recognized by the NLR protein Nalp1 or NLRP1 and mediates cell death (Boyden et al. 2006 Nat Genet 38:240-244).
- Staphylococcus aureus is a Gram positive bacterium responsible for a wide variety of superficial as well as serious life-threatening infections (Lowy et al. 1998. N. Engl. J. Med. 339: 520-525). S. aureus secretes many toxins among which ⁇ -hemolysin has been implicated in the pathogenesis of S. aureus necrotizing pneumonia and various other symptoms in animal models. ⁇ -Hemolysin is secreted as a 33-kDa monomer and oligomerizes, forming heptameric transmembrane pores (Song et al. 1996 Science 274: 1859-1866).

Further, recently it has been discovered that TLR ligands enhance presentation of phagocytosed antigens within major histocompatibility class II MHC molecules [Blander, J. M. and Medzhitov, R., Nature (2006), Vol. 440, pp. 808].

Any suitable route of injection is contemplated by the present invention. Direct injection into a tumor-draining lymph node can ensure the proximity of the DC to T cells in order to induce an antigen-specific T cell driven immune response. The number of loaded DCs to be injected as well as the frequency of injection can be determined experimentally. Clinical criteria for evaluating efficacy of immunotherapies are well defined, in particular for solid tumor (J.
- tumor cells for preparing a composition of the invention may be obtained from the same patient who is to be administered the composition (i.e., the tumor cells may be autologous to the cells of the patient).
- Autologous tumor cells are preferred as they express the same antigens expressed by the patient's tumor cells, and will thus help drive an effective anti-tumor immune response directed against the patient's tumor, by allowing generation of immune response against additional antigens (in addition to the TAA).
- Non-autologous tumor cells may also be used however, since they are engineered to express a TAA-containing fusion protein, wherein the TAA is preferably expressed by the patient's tumor cells.
- DCs may be autologous cells. This is preferred, since self DCs will not stimulate an alloimmune response, and will therefore avoid being eliminated by the host immune system before inducing the anti-tumor immune response.

- TLR5 ligand flagellin within OVA-expressing tumors could induce OVA-specific OT-II CD4 + T cells in vivo was investigated. It was found that expression of flagellin within tumor cells strongly enhanced TAA-specific CD4 + T cell proliferation in vivo ( FIG. 4 ). This finding is consistent with the previous observations demonstrating that TLR ligands enhance presentation of phagocytosed antigens within major histocompatibility class II MHC class II molecules [Blander, J. M. and Medzhitov, R., Nature (2006), Vol. 440, pp. 808].
