Stimulation index [ratio of Toll-like receptor (TLR) expression in stimulated/unstimulated monocytes] for (a) TLR-4 after lipopolysaccharide stimulation and (b) TLR-2 after peptidoglycan stimulation in the different monocyte populations in allergic (n = 10) and non-allergic (n = 10) 5-year-old children. ° = outliers and * = extremes. The line represents stimulation index = 1, which means no up-/down-regulation. □ CD14+CD16+, ▪ CD14+CD16−All CD14 positive cells.
