title: Interaction of large DNA viruses with dendritic cells.
abstract: Dendritic cells (DC) with their unique capacity to prime naïve T cells are crucial in the induction of immunological responses, including anti-tumoral and anti-viral immunity. DC based immunotherapies are thus currently considered a particularly promising approach for cellular immunotherapy. The cloning of tumor associated antigens (TAAs) together with the possibility of manipulating viral genomes by biotechnological techniques has sparked the interest of using genetically modified viruses to transduce DC in order to achieve antigenic expression of TAA with the aim of inducing a protective immune response. An increasing number of modified viral vectors has been designed for gene therapy purposes and consecutively has been used for the ex vivo transduction of DC. It has been shown that viral vectors genetically engineered to express TAA or immune modifiers like cytokines or costimulatory molecules can lead to a high level of transgene expression. Furthermore, these studies have also revealed that viruses have developed several immune evasion mechanisms specifically targeting DC. Therefore, analysing the interactions of viruses with DC is crucial for the development of new viral vectors suitable for the transduction of DC. In this report we describe the interaction of two large DNA viruses, herpes simplex virus type 1 (HSV-1) and vaccinia virus (VV), with DC generated from peripheral blood mononuclear cells.
