No further statistically significant differences concerning the percentage of CD4+ cells expressing IFN-γ [19.2% (7.3–49.8%) vs 17.0% (4.8–29.8%)], IL-8 [9.7% (1.0–23.4%) vs 9.4% (3.2–17.4%)], TNF-α [29.8% (2.5–75.2%) vs 15.4% (3.3–58.3%)], MIP-1β [11.8% (1.1–58.5%) vs 9.7% (2.6–33.4%)] or CD25 [4.3% (0.4–17.5%) vs 4.9% (1.7–16.3%)] were observed between asthma and control groups. Here, CCL4 is linked to asthma.
