In order to evaluate the immunogenicity and the effect of a virosomal influenza vaccine on viral replication and T-cell activation in HIV-infected children receiving highly active antiretroviral therapy (HAART), 29 children infected with HIV-1 vertically (19 primed with a previous influenza vaccination and 10 who were not been immunized against influenza) were immunized with an intramuscular vi...
There is a clear need for an instrument-free molecular diagnostic system for detecting human immunodeficiency virus type 1 (HIV-1) RNA or DNA that can be used in developing countries. Such a test could be used for early diagnosis of HIV-1 infection during infancy and could serve as a surrogate end point for vaccine trials. We developed the IsoAmp HIV-1 assay (BioHelix Corporation), which target...
Despite major advances in HIV-1 therapeutics and prevention strategies, the development of a safe and effective prophylactic HIV-1 vaccine will likely be critical for ending the global HIV-1 epidemic. Yet only four HIV-1 vaccine concepts have been tested for clinical efficacy over the past 30 years. In this Commentary, we describe key hurdles facing the HIV-1 vaccine development field and outli...
Viral diversity is considered a major impediment to the development of an effective HIV-1 vaccine. Despite this diversity, certain protein segments are nearly invariant across the known HIV-1 Group M sequences. We developed immunogens based on the highly conserved elements from the p24(gag) region according to two principles: the immunogen must (i) include strictly conserved elements of the vir...
Here, I update the recent advances and current status of Granulocyte macrophage colony-stimulating factor (GM-CSF), since we have reported for the first time that porcine GM-CSF gene in a DNA vaccine formulation exerted immuno-adjuvant and protective effects against Aujeszky’s (Pseudorabies)viral disease to the natural host pigs with a single vaccination. GM-CSF has been broadly used as an adju...
BACKGROUND In order to develop a more effective prophylactic HIV-1 vaccine it is important optimize the components, improve Envelope glycoprotein immunogenicity as well as to explore prime-boost immunization schedules. It is also valuable to include several HIV-1 subtype antigens representing the world-wide epidemic. METHODS HIVIS-DNA plasmids which include Env genes of subtypes A, B and C to...
Sequence diversity and immunodominance are major obstacles in the design of an effective vaccine against HIV. HIV Env is a highly-glycosylated protein composed of 'conserved' and 'variable' regions. The latter contains immunodominant epitopes that are frequently targeted by the immune system resulting in the generation of immune escape variants. This work describes 12 regions in HIV Env that ar...
BACKGROUND An effective HIV vaccine will likely require induction of both mucosal and systemic cellular and humoral immune responses. We investigated whether intramuscular (IM) delivery of electroporated plasmid DNA vaccine and simultaneous protein vaccinations by intranasal (IN) and IM routes could be combined to induce mucosal and systemic cellular and humoral immune responses to a model HIV-...
