DNA or oligodeoxynucleotides (ODN) containing unmethylated CpG motifs (CpG DNA) activate antigen-presenting cells and switch on T(h)1 immunity to antigen. B cells are synergistically activated by CpG DNA in combination with non-physiologic B cell stimulators such as polyclonal mitogen and surface Ig cross-linkers. This study shows the unexpected finding that not only CpG ODN, but also non-CpG a...
Oligodeoxynucleotides (ODN) which contain immunostimulatory CG motifs (CpG ODN) can promote T helper 1 (Th1) responses, an adjuvant activity that is desirable for vaccination against leishmaniasis. To test this, susceptible BALB/c mice were vaccinated with soluble leishmanial antigen (SLA) with or without CpG ODN as adjuvant and then challenged with Leishmania major metacyclic promastigotes. Cp...
The biomimetic nanovaccines not only promoted antigens endocytosis into dendritic cells via receptor-mediated pathways but also induced cross-presentation eliciting CD8+ T-cell responses. CPG-ODN as an adjuvant further enhanced the anti-tumor immune
In this study, we proposed to modify mesoporous silica nanoparticles (MSNs) with 3-aminopropyltriethoxysilane (NH2-TES), aminoethylaminopropyltriethoxysilane (2NH2-TES) and 3-[2-(2-aminoethylamino)ethylamino] propyl-trimethoxysilane (3NH2-TES) for binding of cytosine-phosphate-guanosine oligodexynucleotides (CpG ODN), and investigated the effect of different amino groups of MSNs on the CpG ODN ...
A specific oligodeoxynucleotide (ODN), ODN MT01, was found to have positive effects on the proliferation and activation of the osteoblast-like cell line MG 63. In this study, the detailed signaling pathways in which ODN MT01 promoted the differentiation of osteoblasts were systematically examined. ODN MT01 enhanced the expression of osteogenic marker genes, such as osteocalcin and type I collag...
Astrocytes synthesize and release endozepines, a family of regulatory peptides, including the octadecaneuropeptide (ODN) an endogenous ligand of both central-type benzodiazepine (CBR) and metabotropic receptors. We have recently shown that ODN exerts a protective effect against hydrogen peroxide (H(2)O(2))-induced oxidative stress in astrocytes. The purpose of the present study was to determine...
background : historically, leishmanization is the most effective protective measure against cutaneous leishmaniasis (cl), cl lesion induced by leishmanization sometimes takes a long time to heal. manipulation of leishmanization inoculums needed to induce a mild and acceptable cl lesion. the aim of this study was to explore if liposomal form of cpg odn (cytosin phosphate guanin oligodeoxynucle...
Type 1 diabetes is considered as Th1 cell mediated autoimmune disease and the suppression of Th1 cells or the activation of Th2 cells has been regarded as a plausible immunologic intervention for the prevention of type 1 diabetogenesis in a rodent model. CpG ODN is an immunostimulatory sequence primarily present in bacterial DNA, viral DNA and BCG. CpG ODN is conventionally classified as a Th1 ...
Oligonucleotides containing unmethylated CpG motifs (cytosine-phosphorothioate-guanine oligodeoxynucleotide (CpG ODN)) are potent immunostimulatory agents capable of enhancing the Ag-specific Th1 response when used as immune adjuvants. We evaluated the cellular mechanisms responsible for this effect. Development of a CTL response was enhanced when mice were immunized with peptide-pulsed dendrit...
Liver fibrosis is characterized by changes in tissue architecture and extracellular matrix composition. Liver fibrosis affects not only hepatocytes but also the non-parenchymal cells such as hepatic stellate cells (HSCs), which are essential for maintaining an intact liver structure and function. Transforming growth factor β1 (TGF-β1) is a multifunctional cytokine that induces liver fibrosis th...
