Abstract

Carbohydrates, as carriers, providing numerous attachment points for the conjugation of peptide antigens and their optimal orientation for the recognition by cells of the immune system, reducing degradation of the attached peptide antigens and many other advantages make carbohydrate‐based vaccine highly promising approach. Multiple copies of a single group A streptococcal (GAS) M protein derived specific peptide antigens (J8 or J14) were coupled onto carbohydrate cores (D‐glucose and D‐galactose) linked to lipophilic amino acids to produce a self‐adjuvanting liposaccharide vaccine against GAS strains. In vivo experiments showed high serum IgG antibody titers against each of the incorporated peptide epitopes, J8 or J14. © 2008 Wiley Periodicals, Inc. Biopolymers (Pept Sci) 90: 611–616, 2008.
