Dendritic cells (DCs) are key antigen-presenting cells (APCs) that act as central modulators of cellular immune responses. Genetic modification of DCs has considerable therapeutic potential in the treatment of a wide spectrum of diseases, including cancer and persistent viral infection. In this report, we show that pre-treatment of DCs with a recombinant adenovirus encoding the major adenovirus receptor, Coxsackie B and adenovirus receptor (CAR), significantly increased the uptake of recombinant adenoviruses (Ads) by primary immature monocyte-derived DCs. This could be correlated with CAR mRNA and surface protein expression. Transduction of DCs by recombinant adenoviruses did not significantly alter cellular viability. Therefore, we propose that pre-treatment of DCs with Ad5-CAR is one strategy to increase the susceptibility of DCs to transduction by recombinant Ads.
