Eosinophils exist as a functionally heterogeneous population. Whether the heterogeneity is driven by cell-intrinsic or extrinsic factors is underexplored. Here, by leveraging single-cell transcriptomic data and epigenomic analysis, the authors propose that local environmental cues define the gene expression program of murine esophageal eosinophils and identify AP-1 family members, including ATF3, as key regulators of gene expression.
