A, CCR7 expression in DCs matured with LPS, OVA and TNF-α cocktail as compared to immature DCs. B, Chemotaxis in response to CCL19 in immature and mature DCs. C, intracellular Ca2+ Kinetics: Ca2+ mobilization and influx in response to CCL19 and CCL21 in immature and mature DCs. Stimuli were added at 90 sec. D, CCL19/CCL21 decreased the side-scatter in mature DCs suggesting some intracellular reorganization. E, forward scatter also decreased in the matured DCs with CCL19/CCL21 stimulation suggesting a decrease in the cell size. Data are representatives of 3 independent experiments.
