    Abstract:
    OBJECTIVE: To study the expression of green fluorescent protein gene and immunogenicity of ES312 vaccine both mediated by Starburst polyamidoamine (PAMAM) dendrimers in vivo. METHODS: The complex of green fluorescent protein or ES312 gene with Starburst PAMAM dendrimers were injected intramuscularly in Balb/c mice. The expression level and distribution of green fluorescent protein gene was detected by flow cytometer, Western blot and immunofluorescence assay. The immunogenicity of DNA vaccine was detected by enzyme-linked immunosorbent assay. RESULTS: The expression of green fluorescent protein mediated by Starburst PAMAM dendrimers was found in heart, liver, spleen, lung, kidney, brain and injected muscle from 2 hours to 7 days after the vaccination. The highest expression level of the gene was detected in kidney, as well as in endothelial cells. The antibody response evoked by the DNA vaccine carried by the Starburst PAMAM dendrimers was significantly higher than that of the net DNA vaccination. Vaccination with Starburst PAMAM dendrimers elicited higher expression level of the gene in brain and kidney than with the net gene itself. CONCLUSION: As a novel non-viral DNA carrier with low self-antigenicity, Starburst PAMAM dendrimers have potential to mediate DNA transfer and expression in vivo.
