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. 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. 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. 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.
