The percentage of CD4+TGF-β+ cells [3.0% (0.5–11.6%) vs 4.1% (0.7–12.9%)], CD4+TGF-β+CD25+ cells [0.4% (0–1.8%) vs 0.5% (0.1–1.7%)], CD4+TGF-β+IL-4+ cells [0.5% (0.1–2.7%) vs 0.4% (0–2.8%)], CD4+TGF-β+IFN-γ+ cells [1.6% (0.3–5.9%) vs 1.4% (0.2–5.1%)] or CD4+TGF-β+TNF-α+ cells [2.2% (0.3–4.9%) vs 1.2% (0.3–4.4%)] did not significantly differ between asthma and control groups. The gene discussed is TGFB1; the disease is asthma.
