Abstract
Nanodisks (ND) are nanometer scale complexes of phospholipid and apolipoprotein that have been shown to function as drug delivery vehicles. ND harboring significant quantities of the bioactive isoprenoid, all trans retinoic acid (ATRA), have been generated and characterized. In the present study a single chain variable antibody (scFv)�apolipoprotein A-I chimera was constructed. The scFv component was directed against the B lymphocyte surface antigen, CD20. Characterization studies showed the fusion protein retains the ability to form ND while the scFv component recognizes the CD20 antigen on the surface of lymphocytes. Studies conducted in a cultured cell model of Mantle Cell Lymphoma revealed that a -CD20 scFv�apolipoprotein A-I ATRA-ND displays enhanced apoptosis induction compared to non targeted, apolipoprotein A-I ATRA-ND. Thus, engineered ND can be used for targeted drug payload delivery to specific tissues.
