Cytokine protein levels over time (0–48 h) showing (a) IL-4, (b) IL-13, (c) IL-6, (d) IL-10 and (E) TNF-α in BAL fluid following saline and HDM bronchial challenges. Data presented as means ± SD for n = 10 sheep (*denotes significant difference between HDM and saline-challenged lobes at the corresponding time point: *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001; #denotes significant difference between time points: #p < 0.05, ##p < 0.01, ###p < 0.001, ####p < 0.0001)
