Summary: |
Immunotherapeutic approaches designed to induce a humoral immune response have recently been developed for possible vaccination to the treatment of Alzheimer's disease (AD). Based on the identification of Aβ(4–10) (FRHDSGY) as the predominant B-cell epitope recognized by therapeutically active antisera from transgenic AD mice, branched polypeptide conjugates with this epitope peptide were synthesized and characterized. In order to produce immunogenic constructs, the Aβ(4–10) epitope alone or together with a promiscuous T-helper cell epitope peptide (FFLLTRILTIPQSLD) were attached via thioether linkage to different branched chain polymeric polypeptides with Ser or Glu in the side chains. A single peptide containing both an Aβ(4–10) and T-helper cell epitope, joined by a dipeptide Cys–Acp spacer, was also attached through the thiol function to chloroacetylated poly[Lys(Seri–DL–Alax)] (SAK). Comparative binding studies of the conjugates with a monoclonal antibody against the β-amyloid(1–17) peptide in mice were performed by direct ELISA. The conformational preferences of carriers and conjugates in water and in a 9:1 triflouroethanol:water mixture (v/v) was analyzed by CD spectroscopy. Experimental data showed that the chemical nature of the carrier macromolecule, and the attachment site of the epitope to the carrier, have significant effects on antibody recognition, but have no marked influence on the solution conformation of the conjugates.
