The P39 and the bacterioferrin (BFR) antigens of Brucella melitensis 16M were previously identified as T dominant antigens able to induce both delayed-type hypersensivity in sensitized guinea pigs and in vitro gamma interferon (IFN-gamma) production by peripheral blood mononuclear cells from infected cattle. Here, we analyzed the potential for these antigens to function as a subunitary vaccine ...
in induction of systemic and mucosal immunity, particulate antigens are more effective than soluble antigens possibly because they are more efficiently endocytosed by mucosal-associated lymphoid tissue (malt) m cells. in this study, we determined the systemic and mucosal immune responses in rabbits following intranasal immunization of tetanus toxoid tt and cpg-odn encapsulated within plga nanos...
We have previously demonstrated that the immune response to an unmethylated cytidine-guanosine (CpG)-containing oligonucleotide (ODN) is greatly enhanced when encapsulated in a lipid nanoparticle (LN-CpG ODN). In this study, the pharmacokinetics, biodistribution and cellular uptake of LN-CpG ODN following intravenous (i.v.) and subcutaneous (s.c.) administration was characterized and correlated...
To determine if deoxycytidyl-deoxyguanosine oligonucleotides (CpG ODN) can be used effectively as nonspecific inducers of innate immune defenses for preventative or therapeutic interventions in infectious disease models for nonhuman primates, the present study evaluated the response of rhesus monkey peripheral blood mononuclear cells to three different synthetic CpG ODN classes by defining the ...
Secondary lymphoid tissue chemokine (SLC), which is expressed in T cell zones of secondary lymphoid organs, including the spleen and lymph nodes, strongly recruits both T lymphocytes and mature dendritic cells. As appropriate interaction of tumor-specific T cells and mature dendritic cells, equipped with tumor antigens, is a prerequisite for effective T cell immunity against established tumors,...
Toll-like receptor (TLR) 9 is an endosomal receptor recognizing bacterial DNA/CpG-containing oligodeoxynucleotides (CpG ODN). Blocking CpG ODN/TLR9 activity represents a strategy for therapeutic prevention of immune system overactivation. Herein, we report that a synthetic peptide (SP) representing the leucine-rich repeat 11 subdomain of the human TLR9 extracellular domain could attenuate CpG O...
Polyethylene glycol (PEG) is used widely in the pharmaceutical industry to improve the pharmacokinetics and reduce the immunogenicity of therapeutic and diagnostic agents. The incorporation of lipid-conjugated PEG into liposomal drug delivery systems greatly enhances the circulation times of liposomes by providing a protective, steric barrier against interactions with plasma proteins and cells....
Synthetic oligodeoxynucleotides expressing CpG motifs (CpG-ODN) are a Toll-like receptor 9 (TLR9) agonist that can enhance the antitumor activity of DNA-damaging chemotherapy and radiation therapy in preclinical mouse models. We hypothesized that the success of these combinations is related to the ability of CpG-ODN to modulate genes involved in DNA repair. We conducted an in silico analysis of...
Y-shape formation increased the immunostimulatory activity of phosphodiester (PO) oligodeoxynucleotides (ODNs) containing CpG motif. In this study, PO CpG ODN or CpG ODN containing nuclease-resistant phosphorothioate (PS) linkages, i.e., PS CpG ODN or PO CpG ODN with three PS linkages at the both ends (PS3), was mixed with two PO- or PS ODNs to prepare Y-shaped DNA (Y-DNA) containing a potent C...
Objective(s): The purpose of this study was preparation and evaluation of PLGA nanospheres containing the influenza virus and different adjuvants, Quillaja saponin (QS) and CpG-ODN. Materials and Methods: Nanospheres were prepared using the double emulsion-solvent evaporation method. The morphological and physicochemical properties were studied by scanning electron microscopy...
