INDUCED INTERNALIZATION OF SURFACE RECEPTORS

摘要

Disclosed is a hetero-bifunctional ligand for use in inducing internalization of a target receptor. The hetero-bifunctional ligand includes a target receptor- binding agent that specifically binds the target receptor linked to an internalizing receptor-binding agent that specifically binds to an internalizing receptor, where the two binding agents are non-identical. Also disclosed is a method of inducing the internalization of a target receptor on a cell. The method includes contacting a cell with a hetero-bifunctional ligand, where binding of the hetero-bifunctional ligand induces internalization of a target receptor of the cell. Also disclosed a method of treating a disease or condition associated with a target receptor using the disclosed hetero-bifunctional ligand and pharmaceutical compositions including a hetero- bifunctional ligand.
