CpG-DNA or its synthetic analog CpG-ODN activates innate immunity through Toll-like receptor 9 (TLR9). However, the mechanism of TLR9 activation by CpG-DNA remains elusive. Here we have identified HMGB1 as a CpG-ODN-binding protein. HMGB1 interacts and preassociates with TLR9 in the endoplasmic reticulum-Golgi intermediate compartment (ERGIC), and hastens TLR9's redistribution to early endosome...
We describe here a short and efficient synthetic route for incorporating terpyridine based metal complexes at the 3'-extremity of both single and bis-oligonucleotide (bis-ODN) stretches to form novel metal complex-ODN conjugates. All single stranded mono and bis-ODN tethered metal complexes and the respective duplex ODNs were characterized by circular dichroism spectroscopy and UV-Vis melting e...
Novel anticancer vaccination regimens that can elicit large numbers of Ag-specific T cells are needed. When we administered therapeutic vaccines containing the MHC class I-presented self-peptide tyrosinase-related protein (TRP)-2(180-188) and CpG-containing oligodeoxynucleotides (CpG ODN) to mice, growth of the TRP-2-expressing B16F1 melanoma was not inhibited compared with growth in mice that ...
PURPOSE CpG oligodeoxynucleotide (CpG-ODN), a TLR9 agonist, activates innate immunity and induces Th1 response. Although the immune modulatory effect of CpG-ODN has been extensively studied, its function in cockroach extract-induced allergic asthma has not been studied. Here, we investigated the inhibitory function of CpG-ODN in cockroach extract-induced asthma in mice with different treatment ...
Endozepines are endogenous ligands for the benzodiazepine receptors and also target a still unidentified GPCR. The endozepine octadecaneuropeptide (ODN), an endoproteolytic processing product of the diazepam-binding inhibitor (DBI) was recently shown to be involved in food intake control as an anorexigenic factor through ODN-GPCR signaling and mobilization of the melanocortinergic signaling pat...
The protozoan parasite Entamoeba histolytica causes invasive amoebiasis characterized by amoebic dysentery and liver abscesses (ALA). The E. histolytica galactose/N-acetyl-D-galactosamine-inhibitable lectin (Gal-lectin), an immunogenic surface molecule involved in colonization and invasion, is a promising vaccine candidate against amoebiasis. Gal-lectin is known to induce Th1 cytokines in macro...
AIM To investigate the effect of inhibition of telomerase with human telomerase reverse transcriptase (hTERT) antisense on tumor necrosis factor-alpha (TNF-alpha)-induced apoptosis in prostate cancer cells (PC3). METHODS Antisense phosphorothioate oligodeoxynucleotide (AS PS-ODN) was synthesized and purified. Telomerase activity was measured using the telomeric repeat amplification protocol (...
BACKGROUND Dendritic cells (DCs) play an important role in immune response and cytidine-phosphate-guanosine (CpG) oligodeoxynucleotides (ODN) as well as interferon (IFN)-alpha have been proven to induce DC maturation. In this study, the synergistic effects of CpG-ODN and IFN-alpha on DC maturation were evaluated. MATERIALS AND METHODS Surface molecules on DCs and the stimulatory responses of ...
BACKGROUND AND PURPOSE Mitogen-activated protein kinase (MAPK) may be associated with the pathogenesis of cerebral vasospasm after subarachnoid hemorrhage (SAH). This study aimed to clarify the role of MAPK expression and activation during cerebral vasospasm and to evaluate the therapeutic effect on cerebral vasospasm using an antisense MAPK oligodeoxynucleotide (ODN). METHODS Antisense MAPK,...
Oligodeoxynucleotides (ODN) containing CpG motifs mimic microbial DNA and are recognized by toll-like receptor 9 on immune cells. The resulting response limits the early spread of infectious organisms and promotes the development of adaptive immunity. In this regard, CpG ODN show promise as immunoprotective agents and as vaccine adjuvants. Previous studies of nonhuman primates showed that admin...
