    摘要: Fusion proteins comprising a single chain antigen-binding domain (scFv) of a monoclonal antibody, linked to an anti-thrombotic agent, anti-inflammatory agent, or a pro-drug thereof are provided, where the polypeptide binds to a binding site (antigen) expressed on the surface of a red blood cell at a density greater than 5,000 copies per red blood cell. Pharmaceutical compositions comprising these fusion proteins, and methods of delivering an anti-thrombotic agent to the surface of a red blood cell via delivery of these fusion proteins, and methods of treating or preventing thrombosis, tissue ischemia, acute myocardial infarction (AMI), ischemic stroke, cerebrovascular disease, pulmonary embolism, or ischemic peripheral vascular disease via administration of the fusion proteins or compositions comprising same are also provided.
