Protein corona formation has been regarded as an obstacle to developing diagnostic and therapeutic nanoparticles for in vivo applications. Serum proteins that assemble around nanoparticles can hinder their targeting efficiency. Virus-based nanoparticles should be naturally predisposed to evade such barriers in host organisms. Here, we demonstrate that virus-like particles derived from mouse polyomavirus do not form a rich protein corona. These particles can be efficiently targeted to cells that overproduce transferrin receptors, e.g., cancer cells, by conjugating transferrin to the particle surface. In this study, we provide evidence that the interaction of virus-like particles with their newly assigned target receptor is not obstructed by serum proteins. The particles enter target cells via a clathrin-dependent endocytic pathway that is not naturally used by the virus. Our results support the notion that the natural properties of virus-like particles make them well-suited for development of nanosized theranostic tools resistant to detargeting by protein coronas.
