Figure 2From: IL-13 expression by blood T cells and not eosinophils is increased in asthma compared to non-asthmatic eosinophilic bronchitis Asthmatic serum increases IL-13 release from healthy T Cells. Mean (SEM) percentage increase in IL-13 release by PBMC from healthy donors after stimulation with mitogen in the presence of 0.1–10% pooled serum from subjects with asthma and non-asthmatic controls. Closed bars PBMC (n = 10) stimulated with asthmatic serum, open bars PBMC (n = 4) stimulated with non-asthmatic serum.Back to article page
