Cytokine responses by SWC3⁺ cells after different stimulations

	IFN-α (U/ml)	TNF-α (pg/ml)
Medium	<3	<5
CpG-ODN D32	19 032 ± 840	841 ± 82
CpG-ODN 2216	12 568 ± 890	585 ± 84
CpG ODN 2006	123 ± 9	<5
LPS	106 ± 4	415 ± 44
pIC	99 ± 2	<5

The SWC3⁺-sorted cells were stimulated with CpG-oligonucleotides (ODNs) (10 µg/ml), lipopolysaccharide (LPS) (1 µg/ml) or Poly I : C (pIC) (10 µg/ml). The cell supernatants were tested for the presence of interferon-α(IFN-α)and tumour necrosis factor-α(TNF-α) by enzyme-linked immunosorbent assay (ELISA) at 24 hr poststimulation.
