Recombinant adenoviruses (rAd) are efficient tools for genetic modification of human dendritic cells (DC) in vitro. Infection of DCs by rAd encoding beta-galactosidase (betagal) results in partial maturation of DCs, as witnessed by the upregulation of major histocompatibility complex and costimulatory molecules. Accordingly, these DCs are more potent stimulators of Th1-type proliferative responses. We now demonstrate that infection of immature DCs with rAd encoding human interleukin (IL)-10 results in the secretion by the DCs of large amounts of IL-10, while not affecting expression of activation markers indicative of partial DC maturation. In contrast to rAd-betagal-infected DCs, rAdIL-10-infected DCs are very poor stimulators of monoclonal and polyclonal Th1-type responses. Instead, stimulation of nonpolarized CD4+ T-cell cultures with rAdIL-10-infected DCs selectively activates and expands an IL-10-producing CD4+ T-cell subset capable of suppressing Th1 responses in vitro. Our data argue that rAd-infected human DCs genetically engineered to produce IL-10 may be exploited for the modulation of harmful Th1-type responses in transplantation and autoimmune diseases.
