| abstract |
The present invention is directed to conjugates that include a polypeptide capable of crossing the blood-brain barrier or entering one or more cell types attached to a transport vector, i.e., a compostion capable of transporting an agent (e.g., a therapeutic agent). In certain cases, the polypeptides are directly conjugated to a lipid or polymeric vector to allow targeted application of a therapeutic agent to treat, for example, a cancer, a neurodegenerative disease, or a lysosomal storage disorder. |
