[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. DC can be used for immunotherapy of cancer and infectious diseases. Transduction of DC by recombinant viral vectors expressing tumor associated antigens (TAA) can result in efficient antigen presentation to T lymphocytes. DC transduced with recombinant vaccinia virus expressing E7 oncoprotein of human papilloma virus 16 are able to protect mice against the growth of syngeneic papillomavirus transformed tumor cells TC1. Antitumor effect was observed also with nonreplicating viruses.
