The present invention relates to molecules that can be targeted to the liver. These liver targeting molecules (e.g.fusions and conjugates) comprise proteins, antibodies or antibody fragments such as immunoglobulin (antibody) single variable domains (dAbs) and also one or more additional molecules which it is desired to deliver to the liver such as interferons. The invention further relates to uses, formulations, compositions and devices comprising such liver targeting molecules. The invention also relates to immunoglobulin (antibody) single variable domains which bind to hepatocytes.
