Abstract

Alzheimer's disease (AD) is a progressive form of dementia characterized by increased production of amyloid-β plaques and hyperphosphorylated tau protein, mitochondrial dysfunction, elevated oxidative stress, reduced protein clearance, among other. Several studies showed systemic modifications of immune and inflammatory systems due, in part, to decreased levels of CD3+ lymphocytes in peripheral blood in AD. Considering that oxidative stress, both in the brain and in the periphery, can influence the activation and differentiation of T-cells, we investigated the 3-nitrotyrosine (3-NT) proteome of blood T-cells derived from AD patients compared to non-demented (ND) subjects by using a proteomic approach. 3-NT is a formal protein oxidation and index of nitrosative stress. We identified ten proteins showing increasing levels of 3-NT in CD3+ T-cells from AD patients compared with ND subjects. These proteins are involved in energy metabolism, cytoskeletal structure, intracellular signaling, protein folding and turnover, and antioxidant response and provide new insights into the molecular mechanism that impact reduced T-cell differentiation in AD. Our results highlight the role of peripheral oxidative stress in T-cells related to immune-senescence during AD pathology focusing on the specific targets of protein nitration that conceivably can be suitable to further therapies. Further, our data demonstrate common targets of protein nitration between the brain and the periphery, supporting their significance as disease biomarkers.

  • Elevated 3-NT levels in age-related diseases such as AD and PD indicate the impact of 3-NT accumulation in human aging.

    “elevated 3-NT levels in age-related diseases, such as AD and PD, indicate the impact of 3-NT accumulation in human aging”

    From Protein oxidation - Formation mechanisms, detection and relevance as biomarkers in human diseases (2021) · cites this paper as [191]

    The Discussion (page unavailable) reports elevated 3-nitrotyrosine in AD lymphocytes and suggests that nitrosative stress might link ageing and AD. The paper does not establish elevated 3-NT in Parkinson’s disease or show that 3-NT accumulation affects human aging generally; its aging link is tentative. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • In AD patients, total 3-NT levels are increased in PBMC compared to non-demented subjects (slot blot).

    “Increased total 3-NT levels in PBMC of AD patients”

    From Protein oxidation - Formation mechanisms, detection and relevance as biomarkers in human diseases (2021) · cites this paper as [191]

    The Redox proteomics data section reports about 25% higher total protein nitration in AD T-cells than in non-demented T-cells, and the Figure Legends identify slot blot as the method. The Subjects section says PBMCs were collected and then fractionated; the reported increase is for T-cells, not PBMCs as a whole. Page numbers are unavailable in our copy. (LLM, conf=0.90)

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.
