Thalidomide (Thal) was shown to be a potent immunomodulating agent. Because of their central role in controlling immunity, we investigated the effects of Thal on monocyte‐derived dendritic cells (Mo‐DC). The addition of 10 μg/ml or 20 μg/ml Thal from the beginning of monocyte culture with granulocyte macrophage‐colony stimulating factor and interleukin (IL)‐4 did not block Mo‐DC differentiation. Moreover, Thal alone could not induce Mo‐DC maturation. However, Thal exerted a modulation of Mo‐DC functional properties. At 10 μg/ml, Thal modified the allostimulatory capacity of DC little, whereas a dose of 20 μg/ml up‐regulated this capacity (P=.05) and increased IL‐12p70 production in a dose‐dependent manner between 10 and 20 μg/ml (P=.001). Mo‐DC generated with 10 μg/ml Thal were poor stimulators of T helper cell type 1 (Th1) responses (P=.01), but 20 μg/ml was able to strengthen Th1 responses (P=.03). Also, Thal induced a significant reduction of IL‐10 production in response to the maturation‐inducing stimulus CD40L. Similarly, tumor necrosis factor α production was significantly decreased when Mo‐DC were exposed to 10 μg/ml Thal, and a dose of 20 μg/ml did not induce any significant changes. The effects of Thal in vitro on the secretion of IL‐12p70 and strengthening of Th1 responses might contribute to the antitumor effects of Thal. Thus, DC appear to be potential targets for the immunomodulatory capacity of Thal, defining a new mechanism of action of this drug.
