The disclosure provides adjuvants, immunogenic compositions, and methods useful for vaccination and immune response. In particular, the disclosure provides a class of adjuvants comprising cationic lipid:co-lipid mixtures and methods for delivering formulated compositions.

Compositions and methods for enhancing immune responses to vaccines

The present invention provides a pharmaceutical composition, comprising a non-infectious, non-integrating polynucleotide construct comprising a polynucleotide encoding an interferon &#x3c9; and one or more cationic compounds. The present invention also provides methods of treating cancer in a mammal, comprising administering into a tissue of the mammal a non-infectious, non-integrating polynucleotide construct comprising a polynucleotide encoding a cytokine. In addition, the present invention also relates to the methodology for selective transfection of malignant cells with polynucleotides expressing therapeutic or prophylactic molecules in intra-cavity tumor bearing mammals. More specifically, the present invention provides a methodology for the suppression of an intra-cavity dissemination of malignant cells, such as intraperitoneal dissemination. Furthermore, the invention relates to compositions and methods to deliver polynucleotides encoding polypeptides to vertebrate cells in vivo, where the composition comprises an aqueous solution of sodium phosphate.

Methods for treating cancer using interferon-&#x3c9;-expressing polynucleotides

The present invention provides a pharmaceutical composition, comprising a non-infectious, non-integrating polynucleotide construct comprising a polynucleotide encoding an interferon &#x3c9; and one or more cationic compounds. The present invention also provides methods of treating cancer in a mammal, comprising administering into a muscle of the mammal a non-infectious, non-integrating DNA polynucleotide construct comprising a polynucleotide encoding a cytokine. In addition, the present invention also relates to the methodology for selective transfection of malignant cells with polynucleotides expressing therapeutic or prophylactic molecules in intra-cavity tumor bearing mammals. More specifically, the present invention provides a methodology for the suppression of an intra-cavity dissemination of malignant cells, such as intraperitoneal dissemination. Furthermore, the invention relates to compositions and methods to deliver polynucleotides encoding polypeptides to vertebrate cells in vivo, where the composition comprises an aqueous solution of sodium phosphate.

Methods for treating cancer using cytokine-expressing polynucleotides

The present invention relates to pharmaceutical compositions and methods to improve expression of exogenous polypeptides into vertebrate cells in vivo, utilizing delivery of polynucleotides encoding such polypeptides. More particularly, the present invention provides the use of salts, in particular sodium and potassium salts of phosphate, in aqueous solution, and auxiliary agents, in particular detergents and surfactants, in pharmaceutical compositions and methods useful for direct polynucleotide-based polypeptide delivery into the cells of vertebrates.
