Epitope-based Vaccine Design Against Common Tree Allergens Using Computational Approaches
Abstract
Allergy-related diseases, driven by type I hypersensitivity reactions, affect over 20% to 25% of the global population and continue to rise. Pollen grains may have allergens that cause hypersensitivity reactions. Pla or 3, Fra e 1, and Bet v 1 are major allergens of pollen grains from the common allergenic trees Platanus orientalis, Fraxinus excelsior, and Betula pendula, respectively, and are employed in this study to design a multi-epitope allergy vaccine using immunoinformatics methods.
The steps after finding the main allergenic epitopes include sequences retrieval, T-cell epitopes selection by IEDB and NetMHCIIpan, B-cell epitopes selection by IEDB, addition of linkers and adjuvant, and construction of multi-epitope vaccine, evaluating antigenicity, allergenicity, and toxicity of vaccine construct, secondary structure prediction, 3-dimensional structure modeling and refinement by GalaxyTBM, validation of the model by ProSA-web, ERRAT, and PROCHECK, and exploring the interaction of the designed molecule with receptor by ClusPro.
The designed vaccine demonstrated favorable properties, including high antigenicity, lack of allergenicity and toxicity, and stable secondary and tertiary structures.
These results suggest that this vaccine has the potential to mitigate allergic responses effectively. However, experimental validation is required to confirm its efficacy and safety.
