Abstract:
This manuscript is an up-to-date review of experimentally validated linear and continuous epitopes identified from arbovirus members of the Flavivirus genus. We summarized 153 immunoreactive peptides from the Dengue virus, Zika virus, Japanese encephalitis virus, West Nile virus, and tick-borne encephalitis virus described in studies published from 1989 to 2020. We included peptides from structural (envelope, capsid, and pre-membrane) and nonstructural (Ns1-5) viral proteins that demonstrated relevant immunoreactivity with antibodies from naturally infected or vaccinated humans. We included peptides that demonstrated relevant reactivity features, such as indicators of disease severity related to immunological or immunopathological outcomes, differential or group diagnostic markers, immunotherapy candidates, and potential for vaccine formulation. The majority of immunoreactive peptides were described for DENV probably due to its long-lasting impact on human health and the lack of efficient vaccines and therapeutic methods. Immune landscape data regarding linear immunoreactive and continuous flavivirus peptides are still scarce, and a complete and more detailed map remains to be elucidated. Therefore, this review provides valuable data for those investigating the antibody response against flavivirus infection.
Insights
This review maps 153 validated linear and continuous epitopes from five flaviviruses, including Dengue virus (DENV). This data aids understanding antibody responses and developing vaccines and therapies against these arboviruses.
Area of Science:
- Virology and Immunology
- Epitope Mapping
- Arbovirus Research
Background:
- Flaviviruses, transmitted by arthropods, pose significant global health threats, necessitating a deeper understanding of host immune responses.
- Effective vaccines and therapeutics for many flavivirus infections are lacking, highlighting the need for detailed immunological data.
- Epitopes, the specific sites recognized by antibodies, are crucial for diagnostics, vaccine design, and immunotherapy.
Purpose of the Study:
- To consolidate and review experimentally validated linear and continuous epitopes from key flavivirus species.
- To analyze the characteristics and potential applications of these identified epitopes.
- To provide a comprehensive resource for researchers studying flavivirus immunity.
Main Methods:
- Systematic literature review of studies published between 1989 and 2020.
- Inclusion of peptides from structural and nonstructural proteins of Dengue virus, Zika virus, Japanese encephalitis virus, West Nile virus, and tick-borne encephalitis virus.
- Focus on peptides demonstrating immunoreactivity with human antibodies from natural infections or vaccinations.
Main Results:
- Compilation of 153 immunoreactive peptides from five major flaviviruses.
- Majority of epitopes identified for Dengue virus (DENV), reflecting its public health burden.
- Epitopes were derived from both structural (envelope, capsid, pre-membrane) and nonstructural (NS1-5) viral proteins.
Conclusions:
- The identified epitopes offer valuable insights into the antibody landscape of flavivirus infections.
- These data are critical for developing improved diagnostic tools, vaccines, and immunotherapies against flaviviruses.
- Further research is needed to fully elucidate the immune landscape of linear and continuous flavivirus epitopes.
