ILC2s respond to various chemokine receptor ligands in a dose-dependent manner. Activation of (A) CCR2, (B) CCR4, (C) CCR5, and (D) CCR6 receptors on ILC2s and T cells was determined following 10-second stimulation with a range of concentrations of the indicated ligands. E, Normalized ILC2 response for each receptor/ligand combination. All data are mean ± SEM from 5 independent experiments. MFI, Mean fluorescence intensity.
