Abstract: The invention provides methods and compositions for increasing the delivery of nucleic acids into a host by administering a nucleic acid encoding a therapeutic nucleic acid along with an agent that modulates Kupffer cell function in the host.

Abstract: Methods and pharmaceutical compositions for modifying cells of a mammalian recipient with DNA encoding a secreted protein such as human interferon in situ are provided. The methods include forming a secreted protein expression system in vivo or ex vivo and administering the expression system to the mammalian recipient. The expression system and methods are useful for the localized and systemic delivery of interferons in situ.

Abstract: Disclosed are methods, nucleic acids, and cells for expressing an exogenous gene in a mammalian cell, involving introducing into the cell a non-mammalian DNA virus (e.g., a baculovirus) having an altered coat protein, the genome of which virus carries an exogenous gene, and growing the cell under conditions such that the gene is expressed. Also disclosed are methods for treating gene deficiency disorders, neurological disorders, or cancers in a mammal by (1) providing to a cell a therapeutically effective amount of a non-mammalian DNA virus having an altered coat protein, the genome of which virus carries an exogenous, therapeutic gene and (2) growing the cell under conditions such that the exogenous gene is expressed in the mammal.

Abstract: A protocol for the ion exchange concentration of baculovirus is presented.

Abstract: This invention relates to delivery of biologically active cargo molecules, such as polypeptides and nucleic acids, into the cytoplasm and nuclei of cells in vitro and in vivo. Intracellular delivery of cargo molecules according to this invention is accomplished by the use of novel transport polypeptides which include HIV tat protein or one or more portions thereof, and which are covalently attached to cargo molecules. The transport polypeptides in preferred embodiments of this invention are characterized by the presence of the tat basic region (amino acids 49-57), the absence of the tat cysteine-rich region (amino acids 22-36) and the absence of the tat exon 2-encoded carboxy-terminal domain (amino acids 73-86) of the naturally-occurring tat protein. By virtue of the absence of the cysteine-rich region, the preferred transport polypeptides of this invention solve the potential problems of spurious trans-activation and disulfide aggregation.

Abstract: This invention relates to E2 trans-activation repressors which interfere with normal functioning of the native full-length E2 transcriptional activation protein of the papillomavirus. Native full-length E2 trans-activation protein activates transcription of papillomavirus only through binding to DNA, and it binds to DNA only in the form of a pre-formed homodimer--a pair of identical polypeptide subunits held together by non-covalent interactions. The E2 trans-activation repressors of this invention are proteins, polypeptides or other molecules that dimerize with full-length native E2 polypeptides to form inactive heterodimers, thus interfering with the formation of active homodimers comprising full-length native E2 polypeptides, thereby repressing papillomavirus transcription and replication. The E2 trans-activation repressors of this invention are advantageously used in the treatment of papillomavirus infections and their associated diseases.
