Popis: Targeting antigens which cannot be readily addressed by genetic vectors is a major challenge in vaccine design. The inter-conversion of carbohydrate antigens into peptide mimetic forms provides a means to broaden the immune response to carbohydrate antigens. Peptides that mimic carbohydrate antigens offer new possibilities to augment immune responses to such antigens that include inducing carbohydrate reactive T-cell responses. Peptide mimeotopes can be formulated in a variety of ways that include multiple antigen peptides (MAP) and as DNA vaccines that prime for different antibody isotypes. On the immunological side we observe that: (i) depending on the immunogen formulation peptide mimetics can be processed by either CD5+ or CD5− B cells; (ii) peptide mimeotope immunization can induce cross-reactive responses to multiple carbohydrate forms; (iii) priming with peptide mimeotopes can enhance carbohydrate immune responses upon boosting and (iv) immunization with peptide mimeotopes can induce carbohydrate reactive T cells.
