Abstract

Genetic studies have shown the association of Parkinson's disease with alleles of the major histocompatibility complex. Here we show that a defined set of peptides that are derived from α-synuclein, a protein aggregated in Parkinson's disease, act as antigenic epitopes displayed by these alleles and drive helper and cytotoxic T cell responses in patients with Parkinson's disease. These responses may explain the association of Parkinson's disease with specific major histocompatibility complex alleles.

  • Adaptive immune system plays an important role in approximately 40% of PD.

    “Recently, numerous evidences suggest that adaptive immune system plays important role in approximately 40% PD.”

    From Role of neuroinflammation in neurodegeneration development (2023) · cites this paper as [74]

    The paper reports that approximately 40% of PD participants in its cohort had immune responses to α-synuclein epitopes and says that evidence suggests a role for acquired immunity. It does not establish that the adaptive immune system plays an important role in approximately 40% of all people with PD; the percentage describes an observed response in this cohort. (LLM, conf=0.85)

  • High number of T cells response to α-synuclein were found in brain of PD patients and mouse model.

    “A high number of T cells response to α-synuclein were found in the brain of PD patients and mouse model.”

    From Role of neuroinflammation in neurodegeneration development (2023) · cites this paper as [74]

    The main text reports α-synuclein-reactive T cells in patients with Parkinson’s disease, and Extended Data Figure 1 measures responses in peripheral blood cells—not in brain tissue. The paper also mentions T-cell responses in mice from prior studies, but it does not establish a high number of α-synuclein-reactive T cells in the brains of either patients or mouse models. The indexed passages provide section labels but no page numbers. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Microglia activation by α-synuclein aggregates or other factors can increase MHC I expression on neurons, enhance presentation of α-synuclein antigens by neurons, which are subsequently killed by α-synuclein reactive T cells.

    “Microglia activation by α-synuclein aggregates or other factors can increase the expression of MHC I expression on neurons, enhance the presentation of α-synuclein antigens by neurons, which were subsequently killed by α-synuclein reactive T cells.74–76”

    From Role of neuroinflammation in neurodegeneration development (2023) · cites this paper as [74]

    The passage labeled Abstract (page unavailable) reports that α-synuclein-activated microglia can induce MHC class I expression on substantia nigra dopamine neurons, and that CD8+ T cells can kill neurons presenting an appropriate MHC I–peptide combination. The paper also reports α-synuclein-reactive T cells in patients, but these passages do not establish that neurons present α-synuclein peptides and are subsequently killed by those specific T cells. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • T cells can recognize certain alpha-synuclein antigenic epitopes, and this is largely mediated by CD4+ T cells and CD8+ T cells in patients with Parkinson's disease.

    “T cells can recognize certain a-synuclein antigenic epitopes, and this is largely mediated by CD4 + T cells and CD8 + T cells in patients with Parkinson's disease.94”

    From The role of gut dysbiosis in Parkinson’s disease: mechanistic insights and therapeutic options (2021) · cites this paper as [94]

    The passage describing responses in nine Parkinson’s disease participants (section labeled Abstract) confirms that T cells recognized α-synuclein antigenic peptides. It says responses were largely mediated by CD4+ T cells, with potential CD8+ contributions; CD8+ cells mediated most of the response in only one participant. The claim overstates the CD8+ role by presenting both cell types as largely mediating the response. (LLM, conf=0.89)

  • The deposition of α-syn protein fibrils into larger aggregates such as Lewy bodies or neurites has been associated with strong immunogenic responses in affected tissues of several neurodegenerative diseases.

    “The deposition of α-syn protein fibrils into larger aggregates such as Lewy bodies or neurites has been associated with strong immunogenic responses in affected tissues of several neurodegenerative diseases (75, 93–97).”

    From Mouse α-synuclein fibrils are structurally and functionally distinct from human fibrils associated with Lewy body diseases (2024) · cites this paper as [93]

    The Abstract (page unavailable) describes α-synuclein aggregates in Parkinson’s disease Lewy bodies and reports immune responses to α-synuclein peptides, including responses to epitopes processed from fibrilized protein. It does not establish that fibril deposition produces strong immune responses in affected tissues across several neurodegenerative diseases; it explicitly says the role of these epitopes in additional synucleinopathies is untested.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
