    摘要: The disclosure provides peptide compositions and immunotherapy compositions comprising alpha-synuclein peptide. The disclosure also provides methods of treating or effecting prophylaxis of neurodegenerative diseases, such as Parkinson’s disease, dementia with Lewy bodies (DLB), Alzheimer’s disease or other synucleinopathies, with alpha-synuclein deposition in a subject, including methods of clearing deposits, inhibiting or reducing aggregation of alpha-synuclein, blocking the uptake by neurons and inhibiting propagation of alpha-synuclein seeds in a subject having or at risk of developing a neurodegenerative disease containing alpha-synuclein accumulations. The methods include administering to such patients the compositions comprising alpha-synuclein peptide.

    摘要: The invention provides methods of detecting alpha-synuclein using a capture antibody and a reporter antibody. The capture antibody binds preferentially to full-length alpha-synuclein phosphorylated at residue 129 (PS129 alpha-synuclein) over unphosphorylated full-length alpha-synuclein. The 11A5 antibody is an example of a suitable capture antibody. The reporter antibody binds to an epitope within residues 40-55 of alpha-synuclein. The 23E8 antibody is an example of such an antibody. Because only a small proportion of alpha-synuclein is phosphorylated high sensitivity of detection below picomolar is advantageous.

    摘要: The invention provides monoclonal antibody 5C1 and related antibodies. The 5C1 antibody binds to an epitope within residues 118-126 of α-synuclein. The antibodies of the invention are useful, for example, for treating and/or diagnosing disorders associated with α-synuclein, particularly accumulation of α-synuclein deposits. Such disorders include Lewy body diseases, such as Parkinson's disease, Diffuse Lewy Body Disease (DLBD), Lewy body variant of Alzheimer's disease (LBV), Combined Alzheimer's and Parkinson disease, pure autonomic failure and multiple system atrophy (MSA).
