Eotaxin-1, (also known as CC-motif chemokine ligand 11, CCL11), is a chemokine that acts as selective chemo-attractant for eosinophil granulocytes (Matthews et al., 1998) and thus is involved in multiple eosinophil-associated diseases such as atopic dermatitis, allergic rhinitis, sinusitis, asthma, ulcerative colitis as well as in the response to parasitic infections (Chao et al., 2012; Geiger et al., 2013; Waddell et al., 2013). This evidence concerns the gene CCL11 and atopic eczema.
