Özet

B cells play a crucial role in adaptive immune responses by producing antibodies that target specific antigens. The identification of B cell epitopes, which are the specific regions on antigens recognized by B cell receptors, is essential for understanding immune responses and developing vaccines. In this study, the most suitable vaccine candidates were predicted for five separate epitope regions that can be used in vaccine development using B cell epitope prediction methods. A total of 98 B cell epitopes were identified in the SARSCoV-2 spike protein from the literature and relevant databases. Among them, 5 epitopes met the accessibility criteria and had accessible residues. The longest accessible subsequences ranged from 4 to 10 amino acids, with an average length of 4.75 amino acids. Additionally, 25% of the accessible residues con- tained polymorphic sites, and 75% overlapped with known protein domains. We also highlight the potential of B cell epitope candidates prediction to con- tribute to new vaccine design strategies and personalized medicine for future vi- rus outbreaks such as SARS-CoV-2. Our findings also suggest that B cell epitope prediction could have a positive impact on developing rapid and effec- tive vaccine strategies for future virus outbreaks. This study demonstrates that B cell epitope prediction could be a significant tool in vaccine development against pathogens with pandemic potential, especially those like SARS-CoV-2.
