Many candidate HIV vaccines are designed to primarily elicit T cell responses. Although repeated immunization with the same vaccine boosts Ab responses, the benefit for T cell responses is ill defined. We compared two immunization regimens that include the same recombinant adenoviral serotype 5 (rAd5) boost. Repeated homologous rAd5 immunization fails to increase T cell responses, but increases...
To evaluate the effects of co-administration of inactivated avian influenza H9N2 virus and adjuvants in waterfowls, 10-d-old ducks were immunized intranasally with inactivated avian influenza virus (IAIV) combined with CpG DNA and sodium cholate. Immunoglobulin A and IgG antibody levels in throat and tracheal tissues increased significantly, as did specific IgA and IgG antibody levels in the se...
the field of vaccinology provides excellent promises to control different infectious and non-infectious diseases. genetic immunization as a new tool in this area by using naked dna has been shown to induce humoral as well as cellular immune responses with high efficiency. this demonstrates the enormous potential of this strategy for vaccination purposes. dna vaccines have been widely used to de...
The delivery of plasmid DNA to the skin can target distinct subsets of dermal dendritic cells to confer a superior immune response. The needle-free immunization technology offers a reliable, safe and efficient means to administer intradermal (ID) injections. We report here that the ID injection of DNA vectors using an NF device (NF-ID) elicits a superior cell-mediated immune response, at much l...
Genetic immunization is a novel form of vaccination in which transgenes are delivered into the host to produce the foreign protein within host cells. Although systemic immune responses have been relatively easy to induce by genetic immunization, the induction of regional and mucosal immunity has often been more challenging. To address the problem of eliciting mucosal immunity in the lung, we ut...
introduction: glycoprotein b (gb) is the major antigen for induction of humoral responses against human cytomegalovirus (hcmv) making it an attractive candidate for immune prophylaxis. in the present study, the humoral immune response of balb/c mice to a truncated hcmv gb protein fused with gfp was evaluated. methods: the truncated gb coding sequence was synthesized and cloned in pegfpn1 eukary...
background: dna immunization with plasmid dna encoding bacterial, viral, parasitic and tumor antigens has been reported to trigger protective immunity. objective: to evaluate the use of a dna immunization strategy for protection against anthrax, a plasmid was constructed. methods: the partialsequence of protective antigen of bacillus anthracis, amino acids 175-764, as a potent immunogenic targe...
background: studies on efficacy of various vaccines that prevent or reduce the primary and recurrent hsv-1 infection have demonstrated the importance of cellular immunity for protection against the infection. we previously used dna vaccination to induce cellular immunity against hsv-1 infection in mice. objective: the aim of our study was to evaluate the effect of light, a member of tnf super f...
DNA vaccines are a promising method of immunization against biothreats and emerging infections because they are relatively easy to design, manufacture, store and distribute. However, immunization with DNA vaccines using conventional delivery methods often fails to induce consistent, robust immune responses, especially in species larger than the mouse. Intramuscular (i.m.) delivery of a plasmid ...
The variant surface antigens of Plasmodium falciparum are an important component of naturally acquired immunity and an important vaccine target. However, these proteins appear to elicit primarily variant-specific antibodies. We tested if naked DNA immunization can elicit more cross-reactive antibody responses and allow simultaneous immunization with several variant constructs. Mice immunized wi...
