摘要

Virus-like particles (VLPs) can be used as efficient carriers of various antigens and therefore serve as attractive tools in vaccine development. Although VLPs of different viruses can be used, VLPs of ssRNA phages have convincing advantages due to their unique properties, including efficient protein production in bacterial and yeast expression systems, low production cost and easy and fast purification. Currently, the range of ssRNA phage VLPs is limited. In particular, this is true for VLPs that tolerate insertions at the N- and C-termini of the coat protein. It is therefore necessary to find new alternatives within the known ssRNA phage VLP range. From previous studies, we found approximately 80 new VLPs forming ssRNA phage coat proteins. In the current study, we attached a model peptide to the N- and C-termini of coat proteins. As a model peptide, we used a triple repeat of 23 N-terminal residues of the ectodomain of the influenza M2 protein, used previously in the development of the flu vaccine. Examining 43 novel phage coat proteins for the ability to form chimeric VLPs, we found ten new promising candidates for further vaccine design, five of which were tolerant to insertions at both the N- and C-termini. Furthermore, we demonstrate that most of the chimeric VLPs have good antigenic properties as judged from their reactivity with anti-M2 antibodies. (C) 2020 Elsevier Ltd. All rights reserved.
