Abstract
Despite widespread vaccination, pertussis resurgence persists due to waning immunity and emerging resistant strains in Bordetella pertussis. This study employs a pangenomics-driven reverse vaccinology approach to identify novel vaccine candidates. Analyzing 160 genomes revealed a closed pan-genome, with approximately 60% conserved genes, including 3389 core genes of which 1312 participate in pathogen-specific pathways. Non-homologous proteins were identified by comparison against human and microbiome proteomes, yielding 205 candidates. Essentiality assessment via the Database of Essential Genes (DEG) refined this to 63 non-homologous essential proteins. A multi-criteria selection process evaluated purifiability based on physicochemical properties and transmembrane helices, accessibility (extracellular or secreted localization), and immunogenicity through antigenicity prediction and B-cell epitope mapping. This pipeline culminated in 11 high-potential vaccine targets. The in silico methodology offers rapidity, cost-effectiveness, and reduced side effects compared with conventional vaccinology, though experimental validation is essential for confirmation.
期刊介绍:
Bioinformatics and Biology Insights is an open access, peer-reviewed journal that considers articles on bioinformatics methods and their applications which must pertain to biological insights. All papers should be easily amenable to biologists and as such help bridge the gap between theories and applications.
