Figure 5

Age-dependent changes in JAK/STAT signaling. (A) The relative increase (Δ) in median pSTAT6 or pSTAT1 activation in infant CD4+ T cells from birth to 1 year. (B) A positive correlation (Spearman rank test) between infant age and the pSTAT1:pSTAT6 ratio in infant blood samples that had sufficient blood volume to analyze both pSTAT1 and pSTAT6 activation in response to IFN-γ or IL-4 stimulation, respectively. Each symbol represents an individual infant; infants of different ages are represented by distinct color symbols as described in Figure 1.
