Characterization of novel cell-penetrating peptides derived from the capsid protein of beak and feather disease virus.

ABSTRACT: Beak and feather disease virus (BFDV) is a 17-20 nm icosahedral virus belonging to the Circoviridae family. Psittacine beak and feather disease (PBFD) is caused by BFDV and its common symptoms include abnormal feather, beak, and claw development, as well as immunosuppression in various bird species. In this study, novel cell-penetrating peptides (CPPs) in the capsid protein (Cap) of BFDV were identified through bioinformatic analyses, after which they were experimentally characterized. The cell-penetrating activities of both CPP1 and CPP2 of BFDV were analyzed through flow cytometry and image analysis. The internalization of CPP1 and CPP2 was both dose- and time-dependent but their uptake efficiencies varied depending on the cell type. The cell-penetrating activities of BFDV CPP1 and CPP2
