The synthetic chimeric gene TBI-HBS encoding the synthesis of immunogenic ENV and GAC epitopes of HIV-1 (immunogenes of T- and B-lymphocytes) and of the surface protein (HBsAg) of the hepatitis B virus was introduced into tomato plants var. Ventura by agrobacterial vector pBIN35TBI-HBS; transgenic tomato plants with the integrated gene TBI-HBS were generated. The integration of the TBI-HBS target gene was confirmed by PCR. The synthesis of antigenic proteins of TBI and HBsAg in fruits of transgenic tomato plants was displayed by immunoassay. The fruits of transgenic tomato plants were fed to experimental mice with a 1-week interval. On days 14 and 28, there was discovered a sufficiently high content of antibodies to the antigenic proteins of HBV and HIV-1 in serum of experimental animals. Antibodies were found in feces of experimental mice; no antibodies were found in the control group of mice. Hence, it was established that the TBI (HIV-1) and HBsAg (HBV) antigens were synthesized in transgenic tomato fruits due to the integrated construction of pBINNp35TBI-HBS in an amount that was enough to induce the immunogenic response in mice to the oral delivery of edible vaccine.
