In addition, the concentrations of IL-4, IL-5, and IL-13, as well as IL-1β, IL-6, and TNF-α, were greatly elevated in BALF and lung tissues, especially in lung tissues, of asthma mice, which were suppressed after the treatment of Ferr-1 and/or 3-MA (Figures 3(c) and 3(d)). The gene discussed is IL4; the disease is asthma.
