Immunol."],"abstract":"<jats:p>Primary Amoebic Meningoencephalitis (PAM), a severe lethal brain disease, is caused by a parasite, <jats:italic>Naegleria fowleri<\/jats:italic>, also known as the \u201cbrain-eating amoeba\u201d. The chances of a patient\u2019s recovery after being affected by this parasite are very low. Only 5% of people are known to survive this life-threatening infection. Despite the fact that <jats:italic>N. fowleri<\/jats:italic> causes a severe, fatal infection, there is no proper treatment available to prevent or cure it. In this context, it is necessary to formulate a potential vaccine that could be able to combat <jats:italic>N. fowleri<\/jats:italic> infection. The current study aimed at developing a multi-epitope subunit vaccine against <jats:italic>N. fowleri<\/jats:italic> by utilizing immunoinformatics techniques and reverse vaccinology approaches. The T- and B-cell epitopes were predicted by various tools. In order to choose epitopes with the ability to trigger both T- and B-cell-mediated immune responses, the epitopes were put through a screening pipeline including toxicity, antigenicity, cytokine-inductivity, and allergenicity analysis. Three vaccine constructs were designed from the generated epitopes linked with linkers and adjuvants. The modeled vaccines were docked with the immune receptors, where vaccine-1 showed the highest binding affinity. Binding affinity and stability of the docked complex were confirmed through normal mode analysis and molecular dynamic simulations. Immune simulations developed the immune profile, and <jats:italic>in silico<\/jats:italic> cloning affirmed the expression probability of the vaccine construct in <jats:italic>Escherichia coli<\/jats:italic> (<jats:italic>E. coli)<\/jats:italic> strain K12. This study demonstrates an innovative preventative strategy for the brain-eating amoeba by developing a potential vaccine through immunoinformatics and reverse vaccinology approaches. This study has great preventive potential for Primary Amoebic Meningoencephalitis, and further research is required to assess the efficacy of the designed vaccine.<\/jats:p>","DOI":"10.3389\/fimmu.2023.1284621","type":"journal-article","created":{"date-parts":[[2023,10,30]],"date-time":"2023-10-30T11:04:29Z","timestamp":1698663869000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":12,"title":["Structural
