Abstract: The present invention relates to an immunostimulatory nanocomplex. The immunostimulatory nanocomplex comprises polyglutamic acid (PGA), a first positively charged substance, a second positively charged substance and a dengue viral protein for holding the dengue viral protein inside. The immunostimulatory nanocomplex is characterized by having a nonuniformally and positively charge distribution along a radial direction thereof. The nonuniformally and positively charge distribution comprises a first electrically charged portion having substantially electrical neutrality, a second electrically charged portion surrounding the first electrically charged portion, and a third electrically charged portion surrounding the second electrically charged portion.

Abstract: The present invention is related to a biodegradable carrier with adjustable zeta potentials and particle sizes, a method for making the same, and a pharmaceutical composition comprising the same. In such a method, a first solution comprising a first biodegradable macromolecule is prepared, and a second solution comprising a second biodegradable macromolecule is also prepared according to a desired zeta potential of a biodegradable carrier and further added into the first solution to form a mixture solution. The biodegradable carrier with the desired zeta potentials is formed by the attraction force between the different electric properties. Then, the mole number of the first biodegradable macromolecule and the second biodegradable macromolecule in the mixture solution are proportionally adjusted according to a desired particle size of the biodegradable carrier. Therefore, the zeta potential and the particle size of the biodegradable carrier are adjustable artificially.

Abstract: The present invention is related to a biodegradable high-efficiency dengue vaccine, a method for making the same, and a pharmaceutical composition comprising the same. The biodegradable high-efficiency dengue vaccine comprises a biodegradable nanocomplex with electric properties holding a dengue viral protein inside. An organism has antibody responses after vaccination with the biodegradable nanocomplex twice. Accordingly, in comparison with the Alum adjuvant and Ribi adjuvant used in the traditional dengue vaccine of the prior art, the vaccination times in the present invention is decreased to further reduce the vaccination cost, so the biodegradable high-efficiency dengue vaccine is good for being a commercial vaccine.

Abstract: The present invention relates to a dengue vaccine, a pharmaceutical composition comprising the same, a nucleotide sequence, and an antibody composition. The dengue vaccine of the present invention includes chimeric nonstructural protein 1, which comprises N-terminus of DV NS1 from amino-acid residues 1 to 270 and C-terminus of JEV NS1 from amino-acid residues 271 to 352 (designated DJ NS1). Therefore, the dengue vaccine without autoimmunity according to the present invention is able to avoid cross-reactions with endothelial cells and platelets, and is able to shorten the bleeding time.

Abstract: The present invention relates to a dengue vaccine, a pharmaceutical composition including the same, and a nucleotide sequence. The dengue vaccine includes N and C termini-deleted nonstructural protein ?NC NS1 with a peptide fragment from amino acids 36 to 270, which is derived from dengue virus nonstructural protein 1 (DV NS1) with deletions of N-terminal region from amino acids 1 to 35 and C-terminal region from amino acids 271 to 352. The dengue vaccine of the present invention is depleted of cross-reactivity with endothelial cells and platelets, and can shorten the bleeding time.
