Abstract
Tremella fuciformis yeast-like conidium (YLC) cells were transformed by co-cultivation with Agrobacterium cells harboring the hepatitis B surface antigen (HBsAg) gene construct under the control of the CaMV35S promoter. Integration of HBsAg DNA into the YLC genome was confirmed by PCR and dot-blot hybridization. Immunoblotting verified expression of the recombinant protein. Oral administration of YLC cells expressing HBsAg in mice significantly increased anti-HBsAg antibody titer levels using a double prime-boost strategy that combined parenteral and oral HBsAg boosters.
