Antigen expression of t cells in healthy children and patients with mild and moderate bronchial asthma. Expression of forkhead box P3 (FoxP3) mRNA in T cells (A) and proportions of CD4⁺CD25^highFoxP3⁺ cells in the CD4⁺ cell population (B), among healthy children and patients with mild and moderate bronchial asthma. Medians are indicated by a line inside each box, the 25^th and 75^th percentiles by the box limits, the lower and upper error bars represent the 10^th and 90^th percentiles, respectively. (C): CD4⁺CD25^high and CD4⁺CD25^high forkhead box P3 (FoxP3)⁺ cells in one representative moderate bronchial asthma children as measured by flow cytometry. Boxes (a) indicate cells in the CD25^high population. Quadrants (b) indicate CD25^highversus CD25^{low/intermediate} cells and FoxP3⁺versus FoxP3^- cells.
