Th2 cells produce cytokines such as IL-4, IL-5, and IL-13, which are pivotal in promoting IgE synthesis and subsequent histamine release (IL-4 and IL-13), eosinophilia (IL-5), and mucus oversecretion, airway hyperresponsiveness, and remodeling (IL-13). Here, IL13 is linked to Increased total eosinophil count.
