Abstract

A method of producing viral antigens in vitro by infecting animal organ tissue rich in mitochondria with a virus, including human hepatitis B virus (HBV), and culturing the infected tissue in vitro is disclosed. A method of producing proteins in vitro by transfecting mitochondria-rich animal tissue with a recombinant HBV-based vector and culturing the transfected tissue in a dynamic tissue culture system is disclosed.

Claims

AMENDED CLAIMS[received by the International Bureau on 11 August 1997 (11.08.97); original claims 1-16 replaced by amended claims 1-17 (2 pages)]
1. A method of producing viral antigens in vitro comprising the steps of: providing a slice of organ tissue of about 2 cm * 2 cm x 260 μm obtained from a nonhumaπ animal to serve as host tissue in in vitro culture, wherein the host tissue is rich in mitochondria; infecting said host tissue in vitro with a virus; culturing said infected host tissue in an in vitro dynamic organ culture system that provides for periodic immersion of said infected host tissue in a tissue culture medium and further provides for gas exchange; allowing said infected tissue to remain in said dynamic organ culture for sufficient time to produce viral antigens; and isolating said viral antigens produced in vitro.
2. The method of Claim 1, wherein the providing step uses host tissue isolated from liver, kidney, pancreas or salivary gland organ tissue.
3. The method of Claim 1, wherein the providing step uses host tissue isolated from a nonhumaπ animal that is a rat, mouse, dog, chicken or frog.
4. The method of Claim 1, wherein the infecting step uses a human virus selected from the group consisting of hepatitis A virus, hepatitis B virus, hepatitis C virus and encephalitis virus.
5. The method of Claim 1, wherein the allowing step produces viral antigens in mitochondria-like organelles in said host tissue in about 24 to about 48 hours.
6. The method of Claim 1, further comprising the step of introducing the isolated viral antigens into an animal to induce an immune response.
7. Viral antigens produced according to the method of Claim 1 and suitable for use in a vaccine.
8. Use of viral antigens produced according to the method of Claim 1 for preparation of a vaccine.
9. A method of producing viral antigens in vitro comprising the steps of: providing a slice of organ tissue of about 2 cm * 2 cm x 260 μm obtained from a nonhuman animal to serve as host tissue in in vitro culture, wherein the host tissue is rich in mitochondria; 1 7
transfecting said host tissue in vitro with a DNA vector comprising a recombinant viral DNA and a DNA sequence to allow expression of the recombinant viral DNA; culturing said transfected host tissue in an in vitro dynamic organ culture system that provides for periodic immersion of said transfected host tissue in a tissue culture medium and further provides for gas exchange; allowing said transfected tissue to remain in the dynamic organ culture for sufficient time to produce viral antigens; and isolating said viral antigens produced in vitro.
10. The method of Claim 9, wherein the providing step uses host tissue isolated from liver, kidney, pancreas or salivary gland organ tissue.
11. The method of Claim 9, wherein the providing step uses host tissue isolated from a nonhuman animal that is a rat, mouse, dog, chicken or frog.
12. The method of Claim 9, wherein the transfecting step uses recombinant viral DNA derived from nucleic acids in hepatitis B virus, hepatitis C virus or a combination thereof.
13. The method of Claim 9, wherein the transfecting step uses recombinant viral DNA derived from nucleic acids in hepatitis B virus and inserted into a human virus DNA sequence coding for a nonstructural viral protein.
14. The method of Claim 9, wherein the allowing step produces viral antigens in mitochondria-like organelles in said host tissue in about 24 to about 48 hours.
15. The method of Claim 9, further comprising the step of infecting or transfecting said host tissue with a helper virus.
16. Viral antigens produced according to the method of Claim 9 and suitable for use in a vaccine.
17. Use of viral antigens produced according to the method of Claim 9 for preparation of a vaccine.
