A recent study showed that IL-35 can reduce airway eosinophilia through the inhibition of eosinophil-attracting chemokines (CCL24 and CCL11) and concluded that IL-35 could be a treatment option for reducing the recruitment of eosinophils into tissues in disorders such as asthma [37]. The gene discussed is CCL24; the disease is Increased total eosinophil count.
