Use of macromolecular assemblies as expression systems for peptides and synthetic vaccines

Abstract

The past decade has witnessed the development of numerous systems for the presentation of antigens on the surface of self-assembling macromolecules. Although the sites for insertion were initially chosen empirically, the determination of the three-dimensional structures of a number of carrier macromolecules has enabled structure-based insertional mutagenesis to be used increasingly. Furthermore, it is now feasible to determine the structure of an inserted sequence as presented in a heterologous environment, making it possible to correlate the detailed structure of a peptide with its immunological properties.
