Ear11 was highly restricted to monocytes (CD11b+ Ly6C+ CD115+), dendritic cells (CD11c+MHCIIhigh), and macrophages (CD11b+F4/80+) and was only induced by type-2 cytokines, allergic challenges, and parasitic infection, but not by pneumoviral (PVM) infection or bacterial (LPS) provocation. This evidence concerns the gene ITGAM and parasitic infectious disease.
