Scientists Identify Gene Region that Fuels Asthma Inflammation

Pollen and house dust mites are two common allergens that cause respiratory distress in asthma patients. But type-2 helper T (Th2) cells and group-2 innate lymphoid cells (ILC2s) release a class of proteins known as type-2 cytokines in response to a variety of asthma triggers. GATA-binding protein 3 (GATA3) is essential for the maturation of Th2 and ILC2.
