Figure 3

Retention of ODN assessed by measuring IL-1β mRNA expression levels induced in PBMCs (cytokine induction assay).

The IL-1β mRNA expression levels were measured by qRT-PCR. New ultrafilter (NUF); Reference ultrafilter (RUF); Challenge solutions (black bars); Filtrate (white bars); **P < 0.001; *P < 0.01 versus buffer and °P < 0.05 versus corresponding challenge solution; n = 3.
