T helper 2 cells (Th2 cells) responses play a central role in asthma pathogenesis, by activating cytokines like interleukin (IL)-4, IL-5, IL-9, and IL-13, which promote eosinophil infiltration into airway wall and excessive mucus production (Hammad and Lambrecht, 2021). This evidence concerns the gene IL13 and asthma.
