CpG oligodeoxynucleotides (CpG ODNs) is a widely used immune adjuvant, which could activate various immune responses including antiviral response through interaction with Toll-like receptor 9 (TLR9) in mammals. In the present study, four types of CpG ODN (CpG-A, CpG-B CpG-C, and CpG-P) were synthesized and injected to the shrimp Litopenaeus vannamei in order to evaluate their immune enhancement...
BACKGROUND Unmethylated cytosine-guanine (CpG) motif-containing oligodeoxynucleotides (ODNs) have been well characterized as agonists of Toll-like receptor 9 (TLR9). ODNs with a phosphorothioate (PTO) backbone have been studied as TLR9 agonists since natural ODNs with a phosphodiester (PD) backbone are easily degraded by a serum nuclease, which makes them problematic for therapeutic application...
Oligodeoxynucleotide (ODN) sequences containing unmethylated cytidine phosphate guanosine (CpG) motifs prevalent in bacterial DNA attenuate allergic lung inflammation in experimental models of asthma but failed to inhibit eosinophilia and improve lung function in patients with asthma. Bacterial respiratory tract infections exacerbate asthma in humans. Increased eosinophil survival is a critical...
CpG oligodeoxynucleotides (ODNs) are synthetic DNA sequences containing unmethylated cytosine-guanine motifs with potent immunomodulatory effects. Via Toll-like receptor 9 agonism of dendritic cells and B cells, CpG ODNs induce cytokines, activate natural killer cells, and elicit vigorous T-cell responses that lead to significant antitumor effects, including improved efficacy of chemotherapeuti...
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...
Adoptive cell transfer immunotherapy using tumor infiltrating lymphocytes (TILs) was an important therapeutic strategy against tumors. But the efficacy remains limited and development of new strategies is urgent. Recent evidence suggested that CpG-ODNs might be a potent candidate for tumor immunotherapy. Here we firstly reported that CpG-ODNs could significantly enhance the antitumor efficacy o...
CpG-ODNs activate dendritic cells (DCs) to produce interferon alpha (IFNα) and beta (IFNβ). Previous studies demonstrated that Toll-like receptor 9 (TLR9) deficient DCs exhibited a residual IFNα response to CpG-A, indicating that yet-unidentified molecules are also involved in induction of IFNα by CpG-A. Here, we report that the catalytic subunit of DNA-dependent protein kinase (DNA-PKcs) but n...
Locally delivered immunomodulators are utilized to treat unresectable tumors and solid tumor resection sites to prevent local recurrence. Synthetic immunostimulatory oligonucleotides such as double-stranded RNA or unmethylated cytosine–guanosine motifs (CpG-ODNs) mimic molecular signatures of pathogens (viruses or bacteria, respectively) and trigger an immunostimulatory cascade including matura...
Acute lymphoblastic leukemia (ALL) is a common malignant disease and a major cause of mortality due to recurrent disease. Immunotherapy is a promising strategy for eradicating minimal residual disease and thus preventing the relapse of leukemia. Apart from stem cell transplantation, CpG oligodeoxynucleotides (ODNs) are excellent candidates for the immunotherapy of leukemia. However, the number ...
BACKGROUND Neonates are particularly vulnerable to infections, in part because of the incomplete development of their immune system. Recent advances in immunostimulatory treatments based on conserved microbial components led us to assess the potential of oligodeoxynucleotides (ODNs) for decreasing the sensitivity of neonates to Cryptosporidium parvum infection. METHODS Neonate mice were treat...
