FIG. 2.
RANTES induction by NDV and UV-irradiated NDV in U373 cells. U373 cells (3 × 105/ml of 10% DMEM/well) in 24-well plates were incubated with increasing doses of NDV for 6 (○), 24 (□), or 48 (■) h (A) or with NDV that had been irradiated with UV for 10 min, at an MOI of 10 or 30, for 48 h (B). Supernatants were assayed for RANTES protein by ELISA. Data are means ± SE from two experiments performed in duplicate. Cells infected with NDV at an MOI of 30 or 60 for 48 h showed significant cell death (data not shown).
