Bionanocapsule (BNC) is a hollow nanoparticle composed of L-protein of the hepatitis B virus surface antigen. BNC can deliver genes or drugs into specific human hepatocytes, but delivery is limited to hepatocytes. In this study, we attempted to alter the specificity of BNCs by genetically introducing cell-penetrating peptides (CPPs), such as arginine-rich peptides, into BNCs. The CPP-fused BNC was efficiently internalized into various cell lines in a short period without significant cytotoxicity. These results show that CPP-BNC could be applied as an efficient carrier for gene and drug delivery.
