TSLP-DCs express OX40L. (A) Each column represents data from human blood CD11c+ immature mDCs either resting or activated by poly I:C or TSLP. The selected 2,166 genes were grouped, based on similarity in expression patterns, by hierarchical clustering as described in Materials and methods. Each row represents relative hybridization intensities of a particular gene across different samples. Colors reflect the magnitude of relative expression of a particular gene across samples. Cluster I, II, and III include genes highly expressed in poly I:C–activated DCs, resting DCs, and TSLP-activated DCs, respectively. Cluster IV includes genes highly expressed in both poly I:C–activated and TSLP-activated DCs. Under culture with different stimuli, expression profiles of the indicated genes (B) and OX40L mRNA expression (C) in DCs were analyzed at the 24-h time point by microarray and RT-PCR, respectively, and surface expression of OX40L on DCs were analyzed at the 48-h time point by flow cytometry (D). OX40L expression on TSLP-DCs were monitored at different time points (E). The staining profile of anti-OX40L mAb and isotype-matched control are shown by the shaded and open areas, respectively. The results of the gene expression profiles (B) are shown as the relative hybridization intensity level by microarray analysis.
