Compositions and methods for dengue virus chimeric constructs in vaccines
Embodiments herein report compositions, uses and manufacturing of dengue virus constructs and live attenuated dengue viruses. Some embodiments concern a composition that includes, but is not limited to, a tetravalent dengue virus composition. In certain embodiments, compositions can include constructs of one or more serotypes of dengue virus, such as dengue-1 (DEN-1) virus, dengue-2 (DEN-2) virus, dengue-3 (DEN-3) or dengue-4 (DEN-4) virus constructs. In other embodiments, constructs disclosed herein can be combined in a composition to generate a vaccine against more one or more dengue virus constructs that may or may not be subsequently passaged in mammalian cells.
1. A dengue-2 virus polypeptide comprising SEQ ID NO: 10.
2. A kit comprising the polypeptide according to claim 1 and a container.
3. A pharmaceutical composition comprising the polypeptide according to claim 1 , and a pharmaceutically acceptable carrier or excipient.
4. The pharmaceutical composition of claim 3 , further comprising a pharmaceutically acceptable adjuvant.
5. The pharmaceutical composition of claim 3 , wherein the composition comprises a tetravalent dengue virus composition capable of inducing an immune response in a subject against all four dengue virus serotypes.
6. A method for inducing an immune response in a subject comprising administering a pharmaceutically acceptable amount of a composition of claim 3 to the subject, wherein the composition induces an immune response to dengue virus in the subject.
7. The pharmaceutical composition of claim 3 , further comprising one or more of the following polypeptides:
a polypeptide comprising SEQ ID NO: 2, 4, 6, 8, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, and 32; wherein SEQ ID NOs: 2, 4, 6, and 8 represent dengue-1/dengue-2 chimeric polypeptides, wherein SEQ ID NOs: 12, 14, and 16 represent dengue-2 virus polypeptides, wherein SEQ ID NOs: 18, 20, 22 and 24 represent dengue-3/dengue-2 chimeric polypeptides, and wherein SEQ ID NOs: 26, 28, 30 and 32 represent dengue-4/dengue-2 chimeric polypeptides.
8. The pharmaceutical composition of claim 7 , further comprising a pharmaceutically acceptable adjuvant.
9. The kit according to claim 2 , wherein the polypeptide is part of a pharmaceutical composition.
10. The kit according to claim 9 , wherein the kit comprises pharmaceutical compositions of all four dengue virus serotypes.
11. A method for inducing an immune response in a subject comprising administering a pharmaceutically acceptable amount of a composition of claim 3 to the subject, wherein the composition induces an immune response in the subject against at least one dengue virus serotype.
