Secretion of IL-13, IFN-γ, and IL-10 cytokines by neonatal CBMCs. IFN-γ, IL-10, and IL-13 secretions were measured in unstimulated supernatants and supernatants after 24 hours' stimulation with allergens (Der f 1 and Fel d 1), phytohemagglutinin (PHA), and lipopolysaccharide (LPS). The median is represented by the black bar. The upper and lower boundaries of the box represent the 25th to 75th percentiles of the data, respectively. Observations < 1.5 times the height of the box beyond either quartile are displayed within the whiskers. (•) represents outliers.
