NK cells were cultured in the presence of herbimycin A (250ng/mL), PDTC (500ng/mL), or neuraminidase (250ng/mL) at 28°C for 1h, followed by twice washings with PBS. Cells were then stimulated for 1 or 16h with NDV 7793 (25HU/105cells), recombinant HN (500ng/mL), or IFN-γ (500ng/mL). The presence of these drugs had no effect on lactate dehydrogenase (LDH) levels, a stable cytosolic enzyme released upon cell lysis, in NK cells.
