The development of active immunotherapy for Alzheimer's disease (AD) requires the identification of immunogens that can ensure a high titer antibody response toward beta-amyloid, whereas minimizing the risks of a cell-mediated adverse reaction. We describe here two novel anti-beta-amyloid vaccines that consist of virus like particles formed by a domain of the bacterial protein E2 that is able to self-assemble into a 60-mer peptide. Peptides 1-11 and 2-6 of beta-amyloid were displayed as N terminal fusions on the surface of the E2 particles. E2-based vaccines induced a fast-rising, robust and persistent antibody response to beta-amyloid in all vaccinated mice. The immune memory induced by a single administration of vaccine (1-11) E2 can be rapidly mobilized by a single booster injection, leading to a very high serum concentration of anti-beta-amyloid antibodies (above 1 mg ml 1). E2 vaccination polarizes the immune response toward the production of the anti-inflammatory cytokine interleukin-4 and does not induce a T cell response to beta-amyloid. Thus, E2-based vaccines are promising candidates for the development of immunotherapy protocols for AD.
