Eosinophilic esophagitis (EoE) is characterized by esophageal eosinophilia, but the underlying mechanisms promoting eosinophil accumulation remain unclear. David Artis and his colleagues describe a new mouse model of EoE-like disease. The development of EoE-like disease is dependent on thymic stromal lymphopoietin (TSLP) and basophils, whereas inhibition of TSLP or depletion of basophils attenuates established disease. Moreover, individuals with EoE have increased TSLP expression and basophils in the esophagus, suggesting that the TSLP-basophil axis can be targeted in patients with EoE.
