Mouse resident lung eosinophils are dependent on IL-5

Purpose: we aimed to characterized eosinophils in the murine model of asthma Methods: Eosinophils were sorted from the lung of naïve and and HDM-induced asthma mice. There after RNA was extracted from the sorted eosinophils and subjected to RNAseq. Results:we demonstrated that resident lung eosinophils require IL-5 for their survival and that the expression of Siglec-F, is regulated by IL-5 . Conclusion: Our data suggest that the distinct eosinophil populations in the asthmatic lung represent a continuum of activation states rather than distinct eosinophil subsets.
