[Vaccinia virus as a vector for transduction of dendritic cells].

Dendritic cells (DC) are very heterogenous population of professional antigen-presenting cells. Precursor cells migrate from bone marrow to peripheral tissues, where immature DC ingest pathogenic microorganisms and then migrate to secondary lymphoid organs. DC differentiate into mature cells that are capable to prime naive T lymphocytes.

Immune response to E7 protein of human papillomavirus type 16 anchored on the cell surface.

To target the E7 protein of human papilloma virus 16 to the cell surface, a fusion gene was constructed. It encodes the signal peptide, part of the immunoglobulin (IgG)-like domain, the transmembrane anchor of vaccinia virus (VV) hemagglutinin (HA), and the complete E7-coding sequence. The fusion gene was expressed under the HA late promoter by a recombinant VV, designated VV-E7-HA.
