[1, 2] How Th2 Cells Work in Asthma
Allergen Trigger: Harmless airborne particles like pollen or dust mites activate an immune response in the lungs.
Cytokine Release: Th2 cells release key signaling proteins: IL-4, IL-5, and IL-13.
Eosinophil Activation: IL-5 recruits white blood cells called eosinophils into lung tissue, causing severe inflammation.
Mucus and Hyperresponsiveness: IL-4 and IL-13 prompt cells to overproduce mucus and make airway muscles hypersensitive and prone to narrowing.
Antibody Production: IL-4 stimulates B cells to produce
allergy-related IgE antibodies, worsening the allergic response. [1, 2, 3, 4]
