  • PROTOZOAN VARIANT-SPECIFIC SURFACE PROTEINS (VSP) AS CARRIERS FOR ORAL DRUG DELIVERY
    Publication number: 20150157735
    Abstract: The invention provides compositions for oral delivery and methods of treatment using VSP carriers, such as Giardia sp. variable surface proteins (VSP), to deliver therapeutic agents. VSP drug carriers can be combined with bioactive peptides, e.g., insulin, glucagon, or hGH, and be administered orally or mucosally. VSP carriers are resistant to acidic pHs and to proteolytic degradation and protect therapeutic agents from degradation in the gastrointestinal tract.
