요약This dissertation explores various aspects of the PP7 virus-like particles (VLPs), leveraging their structural versatility and immunogenic potential for applications ranging from biotechnology to vaccine development. Chapter 2 investigates the assembly tolerance of LeviphagePP7 dimer VLPs, through a library-based approach, for incorporation of random 15-mer peptide sequences on the surface of the capsid. Using protein engineering and molecular biology tools, this study significantly broadened the repertoire of assembly-competent VLP sequences, revealing trends that promotes or disrupts self-assembly. In Chapter 3, we delved into the structural plasticity observed in WT and engineered PP7 VLPs, showcasing a wide range of morphologies influenced by minor alterations in coat protein sequences. This unexpected diversity underscores the adaptability of self-assembling structures and its implications for various applications, shedding light on the evolutionary strategies of viruses. In Chapter 4, we employed PP7 VLPs to display peptide sequences targeting key mutations of SARS-CoV-2 to raise monoclonal antibodies with preferred binding towards key mutations present in several variants of concern. Heterologous prime-boost regimens with VLPpeptide and RBD elicited novel monoclonal antibodies with high affinities towards specific strains. The collective work described in this dissertation is meant to guide the scientific community in exploring the sequence landscape and structure of PP7 while providing an example of its immunological impact.
