Abstract

There are no specific drugs or vaccines for Nipah virus (NiV), which is a new Paramyxovirus that infects swine and humans. This study was conducted to investigate B-cell epitope mapping of the NiV attachment glycoprotein and to construct peptide-based vaccine candidates using the reverse vaccinology approach. To generate the linear B-cell epitope, the NiV isolates were extractad from GenBank, NCBI, using the IEDB web server; peptide modeling was conducted using PEP-FOLD3; docking was conducted using PatchDock and FireDock; and in silico cloning was designed using SnapGene. Various peptides were successfully identified from the NiV attachment glycoprotein based on B-cell epitope prediction, allergenicity prediction, similarity prediction, and toxicity prediction. An in silico cloning design of the pET plasmic was also developed. The peptide “RFENTTSDKGKIPSKVIKSYYGTMDIKKINEGLLD” (1G peptide) is predicted to be a potential candidate for the NiV vaccine as it has several good vaccine characteristics. It increases the immune response of B cells through activation, differentiation into plasma cells, the formation of memory cells, and it may increase IgM/IgG antibody titres for viral neutralization. However, the results of this study should be further verified through in vivo and in vitro analyses

Abstract

Human papillomavirus (HPV) is a virus that causes infection on the surface of the skin and has the potential to cause cervical cancer. This viral infection is characterized by the growth of warts on the skin in various areas of the body, such as the arms, legs, mouth, and genital area. Because the virus can endanger health, it is necessary to design an HPV vaccine to overcome this problem. In this study, we performed a study characterization of HPV types 16 and 18 sequences to obtain immunogenic epitopes retrieved from the National Center for Biotechnology Information (NCBI) web server. Then, epitope prediction was performed using the immune epitope database (IEDB) web server and selected to get the best vaccine candidate for HPV types 16 and 18. We recommend 16P1 as an epitope-based peptide vaccine candidate for HPV type 16 and 18P4 for type 18. Both vaccine candidates are antigenic, non-allergenic, and non-toxic. The 16P1 and 18P4 have the lowest global energy values ​​among the other candidates. However, further research is needed to be able to develop the best vaccine (in vitro and in vivo experiments).
