Background IL-25 and IL-33 belong to distinct cytokine families, but experimental mouse
studies suggest their immunologic functions in type 2 immunity are almost entirely
overlapping. However, only polymorphisms in the IL-33 pathway (IL1RL1 and IL33) have
been significantly associated with asthma in large-cohort genome-wide association studies.
Objective We sought to identify distinct pathways for IL-25 and IL-33 in the lung that might
provide insight into their roles in asthma pathogenesis and potential for therapeutic …
