Mobilization of calcium (A) and chemotaxis (B) of uninfected and HHV-7–infected SupT1 cells in response to SDF-1. HHV-7–infected cultures were analyzed at days 4 (A) or 6 (B) PI. (A) shows transient intracellular calcium flux in response to SDF-1 (40 ng/mL; top panels) or to ionomycin (100 ng/mL; bottom panels). Data are representative of three independent experiments. In (B), chemotaxis was analyzed by using Transwells after induction with the indicated concentration of SDF-1. Data are expressed as the percentage of input cells transmigrated. The mean ± SD of three independent experiments is shown.
