Furthermore, the levels of RANTES (CCL5) (a major eosinophil chemoattractant [120]), IL-5 (known to regulate eosinophil differentiation and survival [121]), and IL-33 (known to further contribute to exacerbated eosinophil [122, 123]) were all increased and coordinate with the increased amount of eosinophilia. Here, CCL5 is linked to Increased total eosinophil count.
