The present invention relates to novel plasmid constructs useful for the delivery of DNA vaccines. The present invention provides novel plasmids having a transcription cassette capable of directing the expression of a vaccine nucleic acid insert encoding immunogens derived from any pathogen, including fungi, bacteria and viruses. The present invention, however, is particularly useful for inducing in a patient an immune response against pathogenic viruses such as HIV, measles or influenza. Immunodeficiency virus vaccine inserts of the present invention express non-infectious HIV virus-like particles (VLP) bearing multiple viral epitopes. VLPs allow presentation of the epitopes to multiple histocompatability types, thereby reducing the possibility of the targeted virus escaping the immune response. Also described are methods for immunizing a patient by delivery of a novel plasmid of the present invention to the patient for expression of the vaccine insert therein. Optionally, the immunization protocol may include a booster vaccination that may be a live vector vaccine such as a recombinant pox virus or modified vaccinia Arbora vector. The booster live vaccine vector includes a transcription cassette expressing the same vaccine insert as the primary immunizing vector.

The Human Immunodeficiency Virus posses a significant threat to the world's population. Current strategies utilized to treat infectious agents have not been adequate to contain and eradicate this deadly viral infection. HIV seeks out its host, a T-Helper cell, by utilizing glycoprotein 120 probes to engage a CD4 cell-surface receptor located on the surface of a T-Helper cell. Developing blood filtering techniques that incorporate filter mediums that offer HIV virion's probes the opportunity to engage the cell-surface receptors they are seeking offers a means of neutralizing and removing HIV. Filtering the blood of a patient with filter mediums comprised of T-Helper cells, sheets of lipid bilayer or virus-like structures with each type of medium possessing cell-surface receptors intended to attract and engage HIV virions provides an effective strategy to prevent and treat AIDS.

Described is a unique class of antiviral molecule that can be applied to control and eliminate HIV infection in patients using myeloablation therapies and replenishment with transformed bone marrow stem cells programmed to express the antiviral molecule. These anti-viral molecules target the HIV genome in a highly conserved domain, and when expressed in cells prior to infection will cause the cell to die upon infection with HIV. Cell death insures no proliferation of new virus. Reconstituting the immune system with cells expressing these antivirals prevents re-establishment of HIV infection from reservoirs in the re-established lymphocyte and macrophage populations. Over time, reservoirs will be depleted entirely, effectively eliminating the virus. In effect, this new type of antiviral can be used to cure HIV infections.

The invention discloses an application of triptolide in preparation of a medicament for treating or preventing human immunodeficiency viruses (HIV). The triptolide is diterpenoid naturally existing in roots of tripterygium wilfordii hook, and can dose-dependently inhibit replication of I type HIV (HIV-1) in cells in vitro. The half inhibitory concentrations on HIV-1 inhibition in TZM-b1 cells, JurkatT lymphocytes and human peripheral blood mononuclear cells are respectively 0.32nM, 0.45nM and 1.1nM. The triptolide has a remarkable inhibiting effect on the replication of the HIV-1 in the TZM-b1 cells, the JurkatT lymphocytes and the human peripheral blood mononuclear cells; and the triptolide is an active ingredient in Chinese medicinal tripterygium wilfordii hook, so the triptolide is wide in source. The compound has a broad prospect for developing anti-HIV-1 medicaments.

The human immunodeficiency virus poses a significant threat to the health and well being of the world's population. Current strategies utilized to eradicate this deadly pathogen have not been effective. A vaccine comprised solely of protein subunits of the glycoprotein 120 probe as the active ingredient, can be effective in stimulating an individual's immune system to repel an HIV infection. The protein subunit of the glycoprotein 120 probe extends from the surface of HIV and is the unique identifier of an HIV virion. When protein subunits of HIV's glycoprotein probe are exclusively presented to the immune system, the antibodies generated will neutralize the glycoprotein 120 probes located on the surface of HIV virions, such that the virus's virions then are incapable of engaging a T-Helper cell and thus the infectious threat posed by HIV is averted.
