Computational Modeling of Immune Response Triggering Immunogenic Peptide Vaccine Against the Human Papillomaviruses to Induce Immunity Against Cervical Cancer.

Papillomaviruses are placed within the family Papillomaviride, and the members of this family have a double-stranded circular DNA genome. Every year, ∼30% of cancers are reported to be human papillomavirus (HPV) related, which represents 63,000 cancers of all infectious agent-induced cancers. HPV16 and HPV18 are reported to be associated with 70% of cervical cancers. The quest for an effective drug or vaccine candidate still continues. In this study, we aim to design B cell and T cell epitope-based vaccine using the two structural major capsid protein L1 and L2 as well as other three important proteins (E1, E2, and E6) against HPV strain 16 (HPV16). We used a computational pipeline to design a multiepitope subunit vaccine and tested its efficacy using computational modeling approaches. Our analysis revealed that the multiepitope subunit vaccine possesses antigenic properties, and using cloning method revealed proper expression and downstream processing of the vaccine construct. Besides this, we also performed immune simulation to check the immune response upon the injection. Our results strongly suggest that this vaccine candidate should be tested immediately for the immune response against the cervical cancer-causing agent. The safety, efficacy, expression, and immune response profiling makes it the first choice for experimental and setup.
