ABSTRACT
Purpose: Virus-like particles (VLPs) have been used as drug carriers for drug delivery systems. In this study, hCC49 single chain fragment variable (scFv)-displaying Rous sarcoma virus-like particles (RSV VLPs) were produced in silkworm larvae to be a specific carrier of an anti-cancer drug. Method: RSV VLPs displaying hCC49 scFv were created by the fusion of the transmembrane and cytoplasmic domains of hemagglutinin from influenza A (H1N1) virus and produced in silkworm larvae. The display of hCC49 scFv on the surface of RSV VLPs was confirmed by enzyme-linked immunosorbent assay using tumor-associated glycoprotein-72 (TAG-72), fluorescent microscopy, and immunoelectron microscopy. Fluorescein isothiocyanate (FITC) or doxorubicin (DOX) was incorporated into hCC49 scFv-displaying RSV VLPs by electroporation and specific targeting of these VLPs was investigated by fluorescent microscopy and cytotoxicity assay using LS174T cells. Results: FITC was delivered to LS174T human colon adenocarcinoma cells by hCC49 scFv-displaying RSV VLPs, but not by RSV VLPs. This indicated that hCC49 scFv allowed FITC-loaded RSV VLPs to be delivered to LS174T cells. DOX, which is an anti-cancer drug with intrinsic red fluorescence, was also loaded into hCC49 scFv-displaying RSV VLPs by electroporation; the DOX-loaded hCC49 scFv-displaying RSV VLPs killed LS174T cells via the specific delivery of DOX that was mediated by hCC49 scFv. HEK293 cells were alive even though in the presence of DOX-loaded hCC49 scFv-displaying RSV VLPs. Conclusion: These results showed that hCC49 scFv-displaying RSV VLPs from silkworm larvae offered specific drug delivery to colon carcinoma cells in vitro. This scFv-displaying enveloped VLP system could be applied to drug and gene delivery to other target cells.
