Area of Science:

  • Immunology and Virology
  • Bioinformatics and Computational Biology

Background:

  • Antibodies (Abs) recognize pathogen epitopes for immune clearance, protecting against disease.
  • Conserved epitopes across pathogen variants (e.g., Influenza, Coronaviruses) offer targets for broad-neutralization.
  • Developing strategies against diverse viral strains requires identifying these conserved regions.

Purpose of the Study:

  • To introduce Epitope Analyzer (EA), a web-based tool for identifying conformational epitope and paratope residues.
  • To enable analysis of broadly neutralizing epitopes by comparing residue similarity across antigen structures.
  • To facilitate the design of targeted vaccines and antibody therapies against multiple viral variants.

Main Methods:

  • Development of a web application, Epitope Analyzer (EA).
  • Utilizing structural analysis of antigen-antibody complexes.
  • Implementing comparative analysis of epitope residues in similar antigen structures.

Main Results:

  • EA rapidly identifies conformational epitope and paratope residues.
  • The tool facilitates the analysis of conserved epitopes by comparing residue similarities.
  • Identified conserved epitopes can guide the development of broad-neutralizing antibody therapies.

Conclusions:

  • Epitope Analyzer is a valuable tool for identifying broadly neutralizing epitopes.
  • Conserved epitope analysis aids in designing effective vaccines and antibody cocktails.
  • The findings support the development of treatments against multiple virus variants and subgroups.
