Yombo et al. demonstrated that hematopoietic, not epithelial HSP70, activated Th2 and type 2 cytokine production as IL-4, IL 5, and IL-13, leading to the maintenance of a pro-allergic response, including eosinophilia, airway inflammation, goblet cell hyperplasia, and mucus hypersecretion [9]. This evidence concerns the gene HSPA1A and Increased total eosinophil count.
