  • Patent number: 11787854
    Abstract: The present invention relates to methods and compositions for treating, preventing, and diagnosing Alzheimer's Disease or other tauopathies in a subject by administering an immunogenic tau peptide or an antibody recognizing the immunogenic tau epitope under conditions effective to treat, prevent, or diagnose Alzheimer's Disease or other tauopathies.

  • Patent number: 11519920
    Abstract: The present invention relates to antibody-based probes (including single domain antibody fragment, scFv molecules, antibodies, antibody fragments, diabodies, and the epitope-binding domains thereof) that are capable of immunospecifically and selectively binding to a phospho-serine-containing epitope of Tau, such as, for example, Tau-phospho-serine 396/404 peptide. Such imaging ligands are useful to detect pathological Tau protein conformer if present in a biological sample, especially in conjunction with the diagnosis of Alzheimer's disease or other tauopathy, and thus provide a diagnostic for Alzheimer's disease and other Tau pathologies. The scFv molecules of the present invention have utility as diagnostic markers for, Alzheimer's disease and related tauopathies and as pharmaceutical compositions for the treatment of such conditions.

  • Publication number: 20220041697
    Abstract: The present invention relates to antibody-based molecules that are capable of preferentially and selectively binding to the C-terminal di-phosphorylated {p}Ser396/{p}Ser404 Tau peptide as well as to the {p}Ser404 Tau peptide and the non-phosphorylated Tau peptide, but does not bind to the {p}Ser396 Tau peptide. Such antibody-based molecules are useful to detect pathological Tau protein conformer if present in a biological sample, especially in conjunction with the diagnosis and/or treatment of Alzheimer's disease or other Tauopathy, and thus provide a diagnostic for Alzheimer's disease and other Tau pathologies. The antibody-based molecules of the present invention also have particular utility as prophylactic and therapeutic molecules for the treatment and/or prevention of Alzheimer's disease and related tauopathies.

  • Patent number: 9700607
    Abstract: Vaccines against prion disease eliciting a humoral immune response when administered mucosally are described. The vaccines comprise a prion protein, a prion protein fragment, or a non-amyloidogenic prion protein homolog and an adjuvant suitable for inducing a humoral immune response after mucosal administration. Suitable adjuvants include cholera toxin subunit B, heat-labile enterotoxin and aluminum hydroxide. Alternatively, the vaccine comprises a vector encoding a prion protein, fragment, or homolog in an attenuated Salmonella host. The vaccines can be used to prevent or treat prion disease in humans and other mammals.

  • Patent number: 9409146
    Abstract: Disclosed herein are methods for treating amyloid disease in humans by clearing amyloid peptides from one or more bodily fluids such as, e.g., blood, of a patient. In particular, the methods are based on the administration of compounds capable of binding to amyloid-beta (A?) or on dialysis of blood or plasma exchange in order to remove A? peptides from the blood circulation, and/or brain or other affected organs.
