Aim: Plant virus-like particles (VLPs) have emerged as a novel platform for delivery of drugs/antibodies. The aim of the present investigation is to establish the entry mechanism of flexuous rod-shaped virus particles into mammalian cells. Methods: Far-Western blot analysis, pull-down and ELISA were used to characterize vimentin and Hsp60 interaction with VLPs. The mode/kinetics of internalization of VLPs was deciphered using pharmacological inhibitors/endosomal markers. Results & discussion: The flexuous rod-shaped VLPs of Pepper vein banding virus (PVBV) enter HeLa and HepG2 cells via cell-surface proteins: vimentin and Hsp60, respectively. VLPs internalize via different modes of endocytosis in HeLa, HepG2 cells and are biodegradable. Vimentin and Hsp60 could be potential epithelial ligands that facilitate targeting of nanoparticles to tumor cells.
