  • Publication number: 20230295283
    Abstract: A vaccine for delaying onset of or for treatment of Alzheimer's disease or an Alzheimer-related disorder in an individual comprises a therapeutically effective amount of a physiologically acceptable protofibril/oligomer comprising N-terminal truncated A?. An antibody for delaying an onset of or for treatment of Alzheimer's disease or an Alzheimer-related disorder in an individual hinds one or more truncated A? protofibrils/oligomers, but exhibits no or substantially no cross-reactivity with full length A? monomers, and optionally said antibody shows cross-reactivity to N-terminal truncated A? monomers. Methods for delaying an onset of or for treatment of Alzheimer's disease or an Alzheimer-related disorder employ the vaccine or antibody. Methods of detecting soluble N-terminal truncated amyloid-beta (A?) protofibrils/oligomers and N-terminal truncated A? monomers employ the antibody.

  • Publication number: 20200215209
    Abstract: Methods for detecting ?-synuclein oligomers in vivo comprise administering an antibody to an individual suspected of carrying soluble ?-synuclein, wherein the antibody is produced from a stabilized soluble ?-synuclein oligomer and is capable of binding the stabilized soluble ?-synuclein oligomer, wherein the stabilized soluble ?-synuclein oligomer has a lower formation rate to a non-soluble aggregated form than a non-stabilized soluble oligomer of the ?-synuclein, and wherein the antibody is labelled with a detectable marker; and detecting the presence of any complex formed between the antibody and soluble ?-synuclein by detection of the marker.
