CpG oligodeoxynucleotides (CpG ODN) are known to be a potent immunoadjuvant for a wide range of antigens. The aim of this study was to evaluate the role of CpG ODN co-encapsulated with rgp63 antigen in cationic liposomes (Lip-rgp63-CpG ODN) in immune response enhancement and protection in BALB/c mice against leishmaniasis. Lip-rgp63-CpG ODN prepared by using dehydration-rehydration vesicle (DRV...
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...
DNA containing unmethylated CpG motifs is intrinsically immunostimulatory, inducing the production of a variety of cytokines and chemokines by immune cells. The strong Th1 response triggered by CpG oligodeoxynucleotide (ODN) inhibits the development of Th2-mediated allergic asthma in mice. This work documents that CpG ODN-induced IL-12 production plays a critical role in this process, because i...
CpG-containing oligodeoxynucleotides (CpG ODN) have broad-ranging immunostimulatory effects, including the generation of antitumor immune responses. Analysis of different CpG ODN have identified two classes: CpG-A ODN, which stimulate high levels of IFN-alpha production from plasmacytoid dendritic cells and weakly activate B cells, and CpG-B ODN, which strongly activate B cells but stimulate lo...
This study examined the ability of E2F decoy oligodeoxynucleotides (ODN) to inhibit proliferation of synovial fibroblasts derived from patients with rheumatoid arthritis (RA). The effect of E2F decoy ODN on cartilage invasion by RA synovium in a murine model of human RA was also investigated. E2F decoy ODN were introduced into synovial tissue and synovial fibroblasts derived from patients with ...
Bacterial DNA and synthetic oligodeoxynucleotides containing the CpG motif (CpG ODN) can activate various immune cell subsets, including natural killer cells and macrophages. We evaluated whether the combination of CpG ODN and antitumor monoclonal antibody is effective at preventing tumor growth in an immunocompetent murine lymphoma model. CpG ODN-activated murine splenocytes induced lysis of t...
OBJECTIVES To evaluate the combination of CpG oligodeoxynucleotide (CpG ODN) and miltefosine for the treatment of experimental visceral leishmaniasis (VL). METHODS The experiments were carried out using BALB/c mice and hamsters, infected with Leishmania donovani. CpG ODN was administered at various doses by the intraperitoneal (ip) route. The dose of CpG ODN (1 nM/single dose) showing best an...
BACKGROUND Although loss of activity of an antioncogene, the p53 tumor suppressor gene product, has been postulated in the pathogenesis of human restenosis, little is known about the role of p53 in the regulation of vascular smooth muscle cell (VSMC) growth. In this study, to clarify the role of p53 in the pathogenesis of restenosis, we examined transfection of antisense p53 oligodeoxynucleotid...
Bacterial genome is characterized by frequent unmethylated cytosine-phosphate-guanine (CpG) motifs. Deleterious effects can occur when synthetic oligodeoxynucleotides (ODN) with unmethylated CpG dinucleotides (CpG-ODN) are administered in a systemic fashion. We aimed to evaluate the effect of intratracheal CpG-ODN on lung inflammation and systemic inflammatory response. C57BL/6J mice received i...
Background—Two phenomena, inflammation and matrix degradation, contribute to the progression of abdominal aortic aneurysm (AAA). Importantly, the inflammation is regulated by the transcription factor nuclear factor (NF)– B, whereas the destruction and degradation of elastin fibers by matrix metalloproteinases (MMP) are regulated by ets. Thus, we developed a novel strategy to treat AAA by simult...
