PPAR-γ activation reduces the hDectin-1–induced proliferation of lymphocytes. DMSO- or TGZ-treated mDCs were stimulated with curdlan for 24 hours before using the cells as stimulators in an MLR assay. The incorporation of ³H-thymidine as a measurement of lymphocyte proliferation was analyzed. The data shown are representative of at least 3 independent experiments. The error bars represent the deviation of the quadruplicates.
