a Concentrations of the chemokines CXCL16 and CCL25 in lung homogenates from IL-33-challenged, IL-25-challenged, OVA-challenged and saline (NS)-challenged mice at various time points. Bars show the mean ± SEM (n = 5 in each group at each time-point). *p < 0.05. b Flow cytometric analysis showing that ILC2s express the surface chemokine receptors CXCR6 and CCR9 following OVA, IL-25 and IL-33 challenge at day 19 (lung tissues from 5 mice/group pooled for staining). Black line: isotype control, red line: IL-25, green line: IL-33, blue line: OVA
