    摘要: An oncolytic adenovirus co-expressing interleukin (IL-12) and shVEGF and a composition for enhancing an anticancer effect are disclosed. The inventors confirmed that, when VEGF suppression and IL-12 expression are co-expressed in immunocompetent murine melanoma or kidney cancer models, an immune function is restored and an anticancer effect is improved. Particularly, it has been revealed that such an improved anticancer effect is associated with an increase in anticancer immunity, an increase in Thl cytokines and prevention of tumor-induced thymic atrophy, and therefore the applicability of a gene delivery system co-expressing IL-12 and shVEGF to cancer gene therapy was identified for the first time.

    摘要: The present invention shows that intranasal administration of E1/E3-defective adenovirus particles may confer rapid and broad protection against viral and bacterial pathogens in a variety of disease settings. Protective responses lasted for many weeks in a single-dose regimen in animal models. When a pathogen-derived antigen gene was inserted into the E1/E3-defective adenovirus genome, the antigen-induced protective immunity against the specific pathogen was elicited before the adenovirus-mediated protective response declined away, thus conferring rapid, prolonged, and seamless protection against pathogens. In addition to E1/E3-defective adenovirus, other bioengineered non-replicating vectors encoding pathogen-derived antigens may also be developed into a new generation of rapid and prolonged immunologic-therapeutic (RAPIT).
