Tyrosine-Based Cross-Linking of Peptide Antigens to Generate Nanoclusters with Enhanced Immunogenicity: Demonstration Using the Conserved M2e Peptide of Influenza A.

ABSTRACT: A method of creating nanoclusters (NCs) from soluble peptide molecules is described utilizing an approach based on a tyrosine-tyrosine cross-linking reaction. A reactive tag comprising histidine and tyrosine residues was introduced at the termini of the peptide molecules. The cross-linking reaction led to the creation of dityrosine bonds within the tag, which allowed for the generation of peptide NCs. We show that it is essential for the reactive tag to be present at both the "N" and "C" termini of the peptide for cluster formation to occur. Additionally, the cross-linking reaction was systematically characterized to show the importance of reaction conditions on final cluster diameter, allowing us to generate NCs of various sizes. To demonstrate the immunogenic potential of the peptide clu
