Abstract: This invention provides expression vectors that comprise a combination of RNA transport elements that improve expression.

Abstract: This invention relates to improved methods of inducing an immune response for the prevention or treatment of HIV-1 infection by using a nucleic acid vaccine in conjunction with a recombinant viral vaccine, e.g., a poxvirus vaccine, to potentiate and broaden the immune response. The present invention further provides a particularly effective vaccine regimen comprising a DNA vaccine used in combination with a poxvirus virus, especially NYVAC or ALVAC.

Abstract: Highly efficient cationic liposomes have been developed as an improved delivery system for biologically-active reagents. A novel structure, the sandwich liposome, is formed and comprises one or more biologically active agents internalized between two bilomellar liposomes. This structure protects the incoming agent and accounts for the high efficiency of in vivo delivery and for the broad tissue distribution of the sandwich liposome complexes. These novel liposomes are also highly efficient carriers of nucleic acids. By using extruded DOTAP:cholesterol liposomes to form complexes with DNA encoding specific proteins, expression has been improved dramatically. Highest expression was achieved in the lung, while increased expression was detected in several organs and tissues.

Abstract: The invention provides a novel post-transcriptional regulatory element that can function as an RNA nucleo-cytoplasmic transport element. The invention also provides for an attenuated HIV-1 hybrid virus for use as a vaccine and a kit incorporating the hybrid virus. The kit also includes instructional material teaching the use of the vaccine, where the instructional material indicates that the vaccine is used for the prophylaxis or amelioration of HIV-1 infection in a mammal; that the vaccine is to be administered to a mammal in a therapeutically effective amount sufficient to express a viral protein; where the vaccine will not cause clinically significant CD4+ cell depletion; and, the expression of the viral protein elicits an immune response to the attenuated HIV-1 virus. The invention further provides for a method for screening for post-transcriptional RNA nucleo-cytoplasmic transport element (NCTE) binding proteins.
