Infection by Listeria monocytogenes causes serious morbidity and mortality during the neonatal period. Previous studies established that immunostimulatory CpG oligodeoxynucleotides (ODN) can increased the resistance of adult mice to many infectious pathogens, including Listeria. This work examines the capacity of CpG ODN to stimulate a protective immune response in newborns. Results indicate th...
Oligodeoxynucleotides (ODN) containing unmethylated CpG dinucleotides in contexts of unique sequence (CpG motifs) is active as adjuvant in induction of cellular and humoral immune responses in young mice. To date, there are only limited reports about effect of CpG ODN on immune responses against hepatitis B (HB) infection in aged mice. Our studies demonstrated there were significant increases i...
PROBLEM CpG oligodeoxynucleotides (ODNs) can induce immunological changes in non-obese diabetic (NOD) mice and increase embryo loss, but little is known about the mechanism. This study aimed to determine the role of adiponectin in CpG ODN-induced pregnancy failure. METHOD OF STUDY Oligodeoxynucleotide 1826 was intraperitoneally injected to NOD mice, and ODN 2216, ODN 2006, and ODN 2395 were u...
Human respiratory syncytial virus (RSV) is the most significant cause of acute lower respiratory infection in children. However, there is no licensed vaccine available. Here, we investigated the effect of five or 20 copies of C-Class of CpG ODN (CpG-C) motif incorporated into a plasmid DNA vaccine encoding RSV fusion (F) glycoprotein on the vaccine-induced immune response. The addition of CpG-C...
We have recently shown that oligodeoxynucleotides (ODN) containing unmethylated CpG dinucleotides (CpG motif) can induce B cells to proliferate, differentiate, and secrete cytokines. In this study we demonstrate that CpG motifs contained in ODN as short as 15 bases in length were quite effective at inducing NK cell lytic activity in vitro in both human and murine lymphocytes. Such ODN were also...
BACKGROUND CpG oligodeoxynucleotides (CpG-ODN) are capable of inducing high amounts of type I IFNs with many immunomodulatory properties. Furthermore, type-I IFNs have been proposed to play a key role in mediating effects of CpG-ODN. The precise role of IFN-beta in the immunomodulatory effects of CpG-ODN is not known. OBJECTIVE Here, we aimed to elucidate the role of IFN-beta in the anti-alle...
CpG oligodeoxynucleotides (ODN) have potent effects on innate and adaptive cellular immune responses. In this report, the ability of CpG ODN to confer long-term immunity and protection when used as a vaccine adjuvant with a clinical grade of leishmanial antigen, autoclaved Leishmania major (ALM), or a recombinant leishmanial protein was studied. In two different mouse models of L. major infecti...
We have investigated the effect of combined treatment with CpG-oligodeoxynucleotide (CpG-ODN) plus Nutlin-3, a small molecule inhibitor of the murine double minute 2/p53 interaction, on the immune activation, cell cycle progression, and apoptosis of peripheral blood B chronic lymphocytic leukemia (B-CLL) cells. CpG-ODN induced a robust up-regulation of immune activation markers (CD54, CD69, CD8...
The activation of phospholipases is one of the earliest key events in receptor-mediated cellular responses to a number of extracellular signaling molecules. Oligodeoxynucleotides containing CpG motifs (CpG ODN) mimic microbial DNA and are immunostimulatory to most vertebrate species. In the present study, we used the production of nitric oxide (NO) as an indicator to evaluate the involvement of...
CpG-Oligodeoxynucleotide (ODN) has two backbones. Phosphorothioate backbone (PS) shows a strong immunostimulating effect while phosphodiester (PE) shows little in vivo. 3' hexameric deoxyriboguanosine-run (3' dG(6)-run) conjugation to PE CpG-ODN has been reported to enhance immunostimulation and to protect against asthma when injected at the time of sensitization in mice. We evaluated the treat...
