Expression of IgE Receptors on Eosinophils

IgE receptors bind either to the Fc portion of the immunoglobulin, and thus belong to the Fc receptor superfamily, or to carbohydrate moieties. The high-affinity receptor (FceRI) and the low-affinity receptor (FceRII/CD23) fall in the first group, while, Mac2/galectin-3, a member of the S-type lectin family, falls in the second one.
