Abstract:Physalis. alkekengi fruit has long been used in traditional Chinese medicine for tumor therapy. In the present study, using plasmids that encode ovalbumin (OVA) gene, we investigate the adjuvant activity of a polysaccharide fraction (PPSB) isolated from P.alkekengi fruit. Formulation by simple procedures of mixing of the OVA-encoding pCI-neo-sOVA plasmid with PPSB not only induced specific antibody responses, but also induced antigen-specific cytotoxic T lymphocyte (CTL) responses (Graph abstract). Furthermore, immunization using this vaccine prevented the growth of OVA-expressing B16-OVA tumor cell growth in the immunized mice. Thus, we provide evidence supporting the adjuvant activity of PPSB in DNA vaccine against tumor.
