INTRACELLULAR PHARMACEUTICAL TARGETING

摘要

A method and composition to target compounds into cells such as eosinophils. A ligand for a CCR-3 eosinophil surface receptor is provided under conditions to bind to the receptor and cause internalization of the ligand-CCR-3 complex. A compound, such as a drug in an active or inactive form, may be bound to the ligand and delivered to an intracellular site of the cell where it may subsequently become activated. The methods and compositions may be used to treat a variety of eosinophil-mediated disorders, for example, allergies.
