<scp>IL</scp>‐33 mediates reactive eosinophilopoiesis in response to airborne allergen exposure

Abstract

These finding suggests that lung IL-33, through innate activation of ILC2s and their production of IL-5, plays a key role in promoting acute reactive eosinophilopoiesis in the bone marrow when naïve animals are exposed to airborne allergens. Therefore, bone marrow eosinophilopoiesis may be affected by atmospheric environmental conditions.
