“Despite current therapeutic developments, high frequencies of patients who undergo hematopoietic stem cell transplantation (HSCT) experience episodes of human cytomegalovirus (HCMV) viral reactivation or become newly infected, which are major causes of morbidity and death for the affected patients. Tetramer monitoring studies post-HSCT have demonstrated that the presence and expansion of HCMV-reactive cytotoxic T lymphocytes (CTL) post-reactivation seemed to protect the patients against recurrent reactivations [1]. No clinical vaccines are currently available against HCMV in the transplantation setting, although several types such as live attenuated, DNA subunit and recombinant vaccines are in development [2]. Studies correlating the level of innate and adaptive immune responses with the

disease outcome have demonstrated that the strongest protection against HCMV is mediated by virus-specific T-cell memory responses and recovery of natural killer cell function [3]. Dendritic cells (DCs) are potent immune adjuvants capable of priming adaptive long-lasting immune responses and of reverting chronicity-induced immunologic anergy or tolerance. Therefore, Dipeptidyl peptidase their use to prevent acute infections or to resolve chronic pathogens in lymphopenic hosts has broad potential. Phase I/II studies including allogeneic SCT recipients at high risk for HCMV disease who were vaccinated with peptide-loaded DCs showed a significant clinical benefit with clear induction of HCMV-specific cytotoxic T lymphocytes (CTLs) [4]. Unfortunately, current ex vivo DC production methodologies in the laboratory remain highly costly and inconsistent, demand several days for production and are impractical for large-scale and routine clinical use. In order to overcome these limitations, our novel approach is the use of lentiviral vectors (LVs) expressing cytokine combinations capable to induce monocytes to autonomously differentiate into dendritic cells after only one day of ex vivo gene transfer.
