摘要:
The present invention provides a recombinant immunogenic obtained by tandem multimerization of a B-cell epitope bearing fragment of Aβ42, within the active loop site of a carrier (display site), preferably bacterial thioredoxin (Yrx). Polypeptides bearing multiple copies of Aβ42 fragments, preferably with an interposed amino acid linker, were constructed and injected into mice in combination with an adjuvant. Elicited antibodies were found to selectively bind to fibrillar and/or oligomers Aβ within neuritic AD plaques.
摘要:
Polypeptide based on a tandem array of repeats of the N-terminal 7 amino acids of Aβ42, preferably positioned within the active loop site of a carrier such as bacterial thioredoxin (Trx) are useful for treating and/or preventing Alzheimer's disease. Antibodies raised against these recombinant constructs were found to have a very strong affinity for Aβ42.

The present invention provides a recombinant immunogenic obtained by tandem multimerization of a B-cell epitope bearing fragment of Aβ42, within the active loop site of a carrier (display site), preferably bacterial thioredoxin (Trx). Polypeptides bearing multiple copies of Aβ42 fragments, preferably with an interposed amino acid linker, were constructed and injected into mice in combination with an adjuvant. Monoclonal antibodies were made which recognize the immunogenic construct comprising a carrier bearing at least one fragment of Aβ42 within an active loop site of the carrier. The elicited antibodies were found to selectively bind to fibrillar and/or oligomers Aβ within neuritic AD plaques.

摘要:
The present invention relates to an immunogenic polypeptide comprising a) a scaffold polypeptide, and b) a L2 polypeptide or a fragment of said L2 polypeptide, wherein said scaffold polypeptide constrains the structure of said L2 polypeptide, or of a fragment of said L2 polypeptide. Moreover, the present invention relates to a vaccine comprising said immunogenic polypeptide. The present invention is also concerned with a method for producing an antibody against human papillomavirus. Also encompassed by the present invention is an antibody obtained by carrying out the said method.
