Synthetic oligodeoxynucleotides (ODN) containing unmethylated CpG motifs mimic the immunostimulatory activity of bacterial DNA. CpG ODN directly stimulate human B cells and plasmacytoid dendritic cells, promote the production of Th1 and proinflammatory cytokines, and trigger the maturation/activation of professional APC. CpG ODN are finding use in the treatment of cancer, allergy, and infection...

The therapeutic benefit from phosphorothioate oligodeoxynucleotides (PS ODN) containing immune stimulatory sequences (ISS) has been demonstrated in animal models of cancer and infection. In particular, when CpG-containing PS ODN are administered to mice, activation of macrophages and dendritic, NK, T, and B cells occurs, resulting in the release of an array of cytokines, including interleukin-1...

Although numerous chemotherapeutic regimens have been evaluated for patients with hormone-refractory prostate cancer, none has improved survival. Testosteronerepressed prostate message-2 (TRPM-2), which is highly up-regulated after androgen withdrawal and during androgen-independent progression in prostate cancer, has been shown to inhibit apoptosis induced by various kinds of stimuli. The obje...

Numerous monoclonal antibodies (mAb) targeting tumor antigens have recently been developed. Antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP) via effector cells such as tumor-infiltrating natural killer (NK) cells and macrophages are often involved in mediating the antitumor activity of mAb. CpG oligodeoxynucleotides (ODN) have a potent antitumo...

Resistance to murine leishmaniasis correlates with development of a CD4(+) T helper 1 (Th1)-predominant immune response. To determine whether immunostimulatory CpG-containing oligodeoxynucleotides (CpG-ODN), known to promote a Th1 immune response, could provide protection from Leishmania infection, CpG-ODN and freeze-thawed (F/T) Leishmania major were coinjected intradermally into susceptible B...

Accessibility of tumors for highly effective local treatment represents a major challenge for anticancer therapy. Immunostimulatory oligodeoxynucleotides (ODN) with CpG motifs are ligands of TLR9, which prime spontaneous antitumor immunity, but are less effective when applied systemically. We therefore developed a liposome-based agent for selective delivery of CpG-ODN into the tumor environment...

Different DNA motifs are required for optimal stimulation of mouse and human immune cells by CpG oligodeoxynucleotides (ODN). These species differences presumably reflect sequence differences in TLR9, the CpG DNA receptor. In this study, we show that this sequence specificity is restricted to phosphorothioate (PS)-modified ODN and is not observed when a natural phosphodiester backbone is used. ...

Background: Hyperemesis Gravidarum (HG) is nausea and vomiting which interfere pregnant women’s daily activities.Ondansetron (ODN) often used off label for the treatment of hyperemesis gravidarum. This study aimed to analyze theefficacy cost ondansetron versus metoclopramide (MCP), a drug that has been in standard regimen thetreatment HG. patients largest hospital Jakarta during year 2012 2016....

OBJECTIVE B-cell lymphoma 2 (Bcl-2) is an important member of the Bcl-2 family of proteins that regulate the induction of apoptosis. This study aims to investigate whether Bcl-2 small interfering RNA (siRNA) combined with miR-15a oligonucleotides (ODN) could enhance methotrexate (MTX)-induced apoptosis in Raji cells. METHODS Chemically synthesized miR-15a ODN and Bcl-2 siRNA were transfected ...

It has been suggested that binding of phosphorothioate oligodeoxynucleotides (P=S ODNs) to macrophage scavenger receptors (SR-AI/II) is the primary mechanism of P=S ODN uptake into cells in vivo. To address the role of scavenger receptors in P=S ODN distribution in vivo, several pharmacokinetic and pharmacological parameters were compared in tissues from scavenger receptor knockout mice (SR-A-/...
