Dendritic cells (DCs) are the most potent antigen presenting cells for inducing T-cell immune responses. The ability to grow human DCs from monocyte precursors provides an abundant source of these cells, which can be modified in vitro to present antigens. Re-administration of modified DCs to patients as vaccines has been shown in some cases to induce immune responses against cancer and infectious disease. Gene delivery to DCs provides an intracellular source of antigen for efficient and persistent loading of major histocompatibility complex (MHC) class I molecules. The aim of this study was to use monocyte-derived DCs (MD-DCs) from healthy donors to compare in vitro gene transfer, mediated by adenovirus, M. bovis Bacillus Calmette Guerin (BCG) and biolistic delivery. Efficiency of transfection and effect on DC phenotype, allostimulatory capacity and cytokine secretion was investigated. Adenovirus and BCG both showed a comparable ability to transfect MD-DCs, whereas the biolistic delivery by gene gun was unsuccessful in the reporter gene delivery. BCG transfection promoted MD-DC maturation as is apparent in the surface phenotype, allostimulatory capacity and cytokine secretion from cells. In comparison, adenovirus and biolistic delivery had a reduced effect on MD-DCs although enhancement of co-stimulatory and MHC molecule expression occurred in the cells of some donors. Both BCG and adenovirus represent useful vectors for gene transfer to human DCs. The effect of BCG on DC maturation may provide additional signals for the induction of antigen-specific T-cell responses.
