An object of the present invention is to provide a safe and effective method for enhancing an immune response and a medicament for preventing or treating Alzheimer disease comprising amyloid β peptide that induces an enhanced immune response. An amyloid β peptide or a portion thereof with addition or insertion of cysteine and a method for enhancing an immune response using the peptide or a method for enhancing an immune response using the peptide together with an adjuvant. A medicament for preventing or treating Alzheimer disease comprising an amyloid β peptide or a portion thereof that induces an enhanced immune response. A DNA vaccine, that may have the same effect, comprising the gene encoding an amyloid β peptide or a portion thereof that induces an enhanced immune response with addition or insertion of cysteine.
A method for enhancing an immune response which comprises administering to a subject in need thereof an immunogenic peptide that induces an enhanced immune response consisting of amino acids selected from the group consisting of the 1st-29th, 1st-30th, 1st-31st, 1st-35th, 1st-36th, 1st-37th, 1st-38th, 1st-39th, 1st-41st and 1st-42nd of an amyloid β peptide with the insertion of cysteine-between the 18th and 19th amino acid residues, between the 25th and 26th amino acid residues, or between the 28th and 29th amino acid residues counted from the N-terminus of the amyloid β peptide.
A method for enhancing an immune response which comprises administering to a subject in need thereof as a DNA vaccine a vector containing a gene fragment encoding an amino acid sequence of an immunogenic peptide that induces an enhanced immune response consisting of amino acids selected from the group consisting of the 1st-29th, 1st-30th, 1st-31st, 1st-35th, 1st-36th, 1st-37th, 1st-38th, 1st-39th, 1st-41st and 1st-42nd of an amyloid β peptide with the insertion of cysteine-between the 18th and 19th amino acid residues, between the 25th and 26th amino acid residues, or between the 28th and 29th amino acid residues counted from the N-terminus of the amyloid β peptide.
