A novel dengue vaccine candidate comprised of a consensus dengue virus envelope protein domain III (cED III) was developed to fight against dengue virus infection. The amino acid sequence of this novel cED III was obtained by alignment of amino acid sequences from different isolates of the four serotypes of dengue viruses. A proof-of-concept study(More)
Enterovirus 71 (EV71) infections in children manifest as exanthema and are most commonly known as hand-foot-and-mouth disease (HFMD). Because it can cause severe neurological complications like poliomyelitis, EV71 has now emerged as an important neurotropic virus in Asia. EV71 virus has been shown to consist of 3 (A, B and C) genotypes and many(More)
The lipid moiety of a novel recombinant lipoprotein, which contains a dengue virus envelope protein domain 3, rlipo-D1E3, has been shown to activate antigen-presenting cells (APCs) as an intrinsic adjuvant. Because the lipid moiety of rlipo-D1E3 contains an unsaturated fatty acid, it is unclear if the receptor usage by bacterially derived lipoproteins is(More)
Targeted cancer-specific gene therapy is a promising strategy for treating metastatic lung cancer, which is a leading cause of lung cancer-related deaths. Previously, we developed a cancer-targeted gene therapy expression system with high tumor specificity and strong activity that selectively induced lung cancer cell killing without affecting normal cells(More)
Identification of the cytotoxic T lymphocyte (CTL) epitopes of tumor antigens is important for effective immunotherapy. We report that a combination of epitope prediction, enzyme-linked immunosorbent assay (ELISA)-based epitope-HLA complex formation, and DNA immunization methods can improve the efficiency and accuracy of CTL epitope studies. In this study,(More)
Enterovirus 71 (EV71) and coxsackievirus A16 (CVA16) are major causative agents of hand, foot, and mouth diseases (HFMDs), and EV71 is now recognized as an emerging neurotropic virus in Asia. Effective medications and/or prophylactic vaccines against HFMD are not available. The current results from mouse immunogenicity studies using in-house standardized RD(More)
The recombinant nucleocapsid (rN) protein of the coronavirus (CoV) responsible for severe acute respiratory syndrome (SARS) was cloned and expressed in Escherichia coli, extracted from cell lysates containing 6M urea, then purified by Ni(2+)-affinity chromatography. In animal immunogenicity studies, we found that most anti-rN protein antibodies were IgG2a(More)
Three peptides, D1 (amino acid residues 175-201), D2 (a.a. 434-467), and TM (a.a. 1128-1159), corresponding to the spike protein (S) of severe acute respiratory syndrome corona virus (SARS CoV) were synthesized and their immunological functions were investigated in three different animals models (mice, guinea pigs, and rabbits). The peptides mixture(More)
PURPOSE To enhance the water affinity of W/O emulsion-adjuvanted vaccines, we used three bioresorbable polymers named PEG-b-PLA, PEG-b-PCL, and PEG-b-PLACL as hydrophilic emulsifier to stabilize the interfaces between the oily Montanide ISA 51 adjuvant and the antigen media. METHODS Polymers were synthesized by ring-opening polymerization of lactide(More)
