Monocytes (5 × 106/ml) were incubated with either opsonized S. aureus (ratio of 1:20) or zymosan particles (0.5 mg/ml) for 1 h (experiments 6 and 7) or 6 h (experiments 1 to 5). Thereafter, culture supernatants were collected and concentrated, and sFasL was detected by ELISA. ND, not determined.
Heat-killed S. aureus was used.
