    摘要: Various aspects of the invention provide for capsids, parvovirus capsids, hybrid parvovirus capsids, parvovirus vectors, hybrid parvovirus vectors, hybrid parvovirus particles and parvovirus particles containing polypeptides in which the sequence YCDGFYACYMDV (SEQ ID NO: 3) has been substituted into the VP2 loop of the B19 capsid protein. Polypeptides in which the sequence YCDGFYACYMDV (SEQ ID NO: 3) has been substituted into the VP2 loop of the B19 capsid protein are also provided (e.g., SEQ ID NO: 2). Other aspects of the invention provide capsids, parvovirus capsids, hybrid parvovirus capsids, parvovirus vectors, hybrid parvovirus vectors, hybrid parvovirus particles and parvovirus particles containing a polypeptide comprising SEQ ID NO: 2. Also provided in various aspects of the invention are pharmaceutical compositions and methods of delivering therapeutic agents and/or reporter peptides/proteins to target cells. Finally, methods of treating diseases characterized by cells expression HER2/neu receptors are also provided.
