ODN 1585 is a potent inducer of IFN and TNFα production. ODN 1585 is a potent stimulator of NK (natural killer) function. ODN 1585 increases CD8+ T-cell function, including the CD8+ T cell-mediated production of IFN-γ. ODN 1585 induces regression of established melanomas in mice. ODN 1585 can confer complete protection against malaria in mice. ODN 1585 can be used for acute myelogenous leukemia (AML) and malaria research. ODN 1585 can be used as a vaccine adjuvant[1][2][3].
ODN 1585 (3 μg/mL, 48 h) induces PBMC producing IFN-α in the nanogram range[3].
ODN?1585 increases the percentage of CD69+ (early marker of activation) NK cells within 24?h (26±7%)[3].
CpG ODN (0.6μg/mL, 18 h) stimulates NK cell-mediated lysis of K562 cells[3].
ODN 1585 (50-500 μg, Injection into the tibialis anterior muscle, single) protects 20 to 90% of mice from sporozoite infection[1].
ODN 1585 (100 μg/dose, IP, twice weekly) is determined to be optimal for the induction of antitumor responses in several systems involving comparisons of 30, 100, and 300 μg/injection[2].
| Animal Model: | BALB/c ByJ mice (4- to 8-week-old, female, 6-18 mice in each group)[1] |
| Dosage: | 50, 100, 200, or 500 μg (in 50 μL of saline) |
| Administration: | Injection into the tibialis anterior muscle, single (at 7, 2, or 1 day(s) prior to sporozoite infection, on the day of infection, and/or at 1 day postinfection) |
| Result: | Protected 20 to 90% of mice from infection when the ODN 1585 was administered around the time of sporozoite challenge with doses of 50 to 500 μg. The highest level of protection (90%) resulted from administration of 200 μg of CpG ODN 1585 the day before challenge or 100 μg of CpG ODN 1585 on the day before and the day of challenge. |

Interleukin-12- and gamma interferon-dependent protection against malaria conferred by CpG oligodeoxynucleotide in mice
Infect Immun 2001 Mar;69(3):1643-9.PMID:11179339DOI:10.1128/IAI.69.3.1643-1649.2001.
Unmethylated CpG dinucleotides in bacterial DNA or synthetic oligodeoxynucleotides (ODNs) cause B-cell proliferation and immunoglobulin secretion, monocyte cytokine secretion, and activation of natural killer (NK) cell lytic activity and gamma interferon (IFN-gamma) secretion in vivo and in vitro. The potent Th1-like immune activation by CpG ODNs suggests a possible utility for enhancing innate immunity against infectious pathogens. We therefore investigated whether the innate immune response could protect against malaria. Treatment of mice with CpG ODN 1826 (TCCATGACGTTCCTGACGTT, with the CpG dinucleotides underlined) or 1585 (ggGGTCAACGTTGAgggggG, with g representing diester linkages and phosphorothioate linkages being to the right of lowercase letters) in the absence of antigen 1 to 2 days prior to challenge with Plasmodium yoelii sporozoites conferred sterile protection against infection. A higher level of protection was consistently induced by CpG ODN 1826 compared with CpG ODN 1585. The protective effects of both CpG ODNs were dependent on interleukin-12, as well as IFN-gamma. Moreover, CD8+ T cells (but not CD4+ T cells), NK cells, and nitric oxide were implicated in the CpG ODN 1585-induced protection. These data establish that the protective mechanism induced by administration of CpG ODN 1585 in the absence of parasite antigen is similar in nature to the mechanism induced by immunization with radiation-attenuated P. yoelii sporozoites or with plasmid DNA encoding preerythrocytic-stage P. yoelii antigens. We were unable to confirm whether CD8+ T cells, NK cells, or nitric oxide were required for the CpG ODN 1826-induced protection, but this may reflect differences in the potency of the ODNs rather than a real difference in the mechanism of action of the two ODNs. This is the first report that stimulation of the innate immune system by CpG immunostimulatory motifs can confer sterile protection against malaria.
Intranasal treatment with CpG-B oligodeoxynucleotides protects CBA mice from lethal equine herpesvirus 1 challenge by an innate immune response
Antiviral Res 2019 Sep;169:104546.PMID:31247247DOI:10.1016/j.antiviral.2019.104546.
Equine herpesvirus 1 (EHV-1) is the causative agent of a number of equine disease manifestations, including severe disease of the central nervous system, respiratory infections, and abortion storms. Our results showed that intranasal treatment with CpG-B oligodeoxynucleotides (ODN 1826) protected CBA mice from pathogenic EHV-1 RacL11 challenge. The IFN-γ gene and seven interferon-stimulated genes (ISGs) were upregulated 39.4- to 260.3-fold at 8 h postchallenge in the lungs of RacL11-challenged mice that had been treated with CpG-B ODN. Interestingly, IFN-γ gene expression was upregulated by 26-fold upon RacL11 challenge in CpG-B ODN-treated mice lungs as compared to that of CpG-A ODN (ODN 1585)-treated mice lungs; however, the seven ISGs were upregulated by 2.4-5.0-fold, suggesting that IFN-γ is a major factor in the protection of CBA mice from the lethal challenge. Pre-treatment with IFN-γ significantly reduced EHV-1 yield in murine alveolar macrophage MH-S cells, but not in mouse lung epithelial MLE12 cells. These results suggest that CpG-B ODN may be used as a prophylactic agent in horses and provide a basis for more effective treatment of EHV-1 infection.
Induction of protective immunity against MHC class I-deficient, HPV16-associated tumours with peptide and dendritic cell-based vaccines
Int J Oncol 2010 Mar;36(3):545-51.PMID:20126973DOI:10.3892/ijo_00000528.
Downregulation of MHC class I expression on the cell surface is a common mechanism by which tumour cells, including cervical carcinoma, can escape the T cell-mediated anti-tumour immunity. This downregulation represents an obstacle for the efficacy of anti-tumour vaccines. In this study, we investigated the efficacy of prophylactic peptide and peptide-pulsed dendritic cell-based vaccines in a murine model of experimental MHC class I-deficient tumours (TC-1/A9), expressing E6/E7 oncogenes derived from HPV16, and compared the efficacy of particular vaccination settings to anti-tumour protection against parental MHC class I-positive TC-1 tumours. Peptide vaccine based on the 'short' peptide E749-57 harbouring solely the CTL epitope and co-administered to the C57BL/6 mice with CpG oligodeoxynucleotide (CpG ODN) 1826 was effective against MHC class I-positive but not -deficient tumours, while the 'longer' peptide E744-62 (peptide 8Q, harbouring CTL and Th epitopes)-based vaccines were also effective against MHC class I-deficient tumours. We have compared the adjuvant efficacies of two CpG ODN, CpG ODN 1826 and CpG ODN 1585. The 8Q peptide immunisation combined with CpG ODN 1585 inhibited growth of the TC-1/A9 tumours more effectively as compared to CpG ODN 1826. Further, we investigated the efficacy of cellular vaccines based on ex vivo cultured dendritic cells pulsed with either E749-57 or E744-62 peptides and matured with CpG ODN 1826. Unlike in the peptide immunisation setting, treatment with dendritic cells pulsed with a 'short' peptide resulted in the tumour growth inhibition, albeit weaker as compared to the immunisation with the longer peptide. Our data demonstrate that peptide and dendritic cell-based vaccines can be designed to elicit protective immunity against MHC class I-deficient tumours.
Inhibitory effects of unmethylated CpG oligodeoxynucleotides on MHC class I-deficient and -proficient HPV16-associated tumours
Int J Cancer 2006 Apr 1;118(7):1836-42.PMID:16217768DOI:10.1002/ijc.21546.
Unmethylated oligodeoxynucleotides containing guanine-cytidine dimers (CpG ODN) have been described as potent inducers of selected antitumour immune responses and the immunotherapeutic efficacy of CpG ODN has been examined either alone or as a vaccine adjuvant. We hypothesized that CpG ODN therapy could be an effective tool for immunotherapy of not only conventional MHC class I(+) tumours but also of those tumours that have lost MHC class I expression during their progression. To address this hypothesis, we employed the animal model resembling MHC class I-proficient and -deficient human papilloma virus (HPV) 16-associated tumours. A cell line transformed with HPV16 E6 and E7 oncogenes, TC-1, as a prototype of MHC class I-positive line, and its MHC class I-deficient sublines TC-1/A9 and TC-1/P3C10 were injected into syngeneic C57BL/6 mice and the growing tumours were subjected to immunotherapy with CpG ODN 1826. The therapy started either 1 day after the challenge with the tumour cells or later, when the tumours had reached a palpable size. In both settings, CpG ODN 1826 significantly reduced the growth of MHC class I-proficient and -deficient tumours. Furthermore, we demonstrated that CpG ODN 1585, whose mechanism of action preferably involves indirect activation of the natural killer cells, induced regression of the MHC class I-deficient tumours TC1/A9 but not of the MHC class I-proficient tumours TC-1. This study infers that synthetic CpG ODN have a potential for the therapy of both MHC class I-proficient and -deficient tumours and thus could be also used against tumours that tend to down-regulate their MHC class I expression.
A TLR9 agonist promotes IL-22-dependent pancreatic islet allograft survival in type 1 diabetic mice
Nat Commun 2016 Dec 16;7:13896.PMID:27982034DOI:10.1038/ncomms13896.
Pancreatic islet transplantation is a promising potential cure for type 1 diabetes (T1D). Islet allografts can survive long term in the liver parenchyma. Here we show that liver NK1.1+ cells induce allograft tolerance in a T1D mouse model. The tolerogenic effects of NK1.1+ cells are mediated through IL-22 production, which enhances allograft survival and increases insulin secretion. Increased expression of NKG2A by liver NK1.1+ cells in islet allograft-transplanted mice is involved in the production of IL-22 and in the reduced inflammatory response to allografts. Vaccination of T1D mice with a CpG oligonucleotide TLR9 agonist (ODN 1585) enhances expansion of IL-22-producing CD3-NK1.1+ cells in the liver and prolongs allograft survival. Our study identifies a role for liver NK1.1+ cells, IL-22 and CpG oligonucleotides in the induction of tolerance to islet allografts in the liver parenchyma.
