Abstract

Oxidative stress is increased in systemic lupus erythematosus (SLE), and it contributes to immune system dysregulation, abnormal activation and processing of cell-death signals, autoantibody production and fatal comorbidities. Mitochondrial dysfunction in T cells promotes the release of highly diffusible inflammatory lipid hydroperoxides, which spread oxidative stress to other intracellular organelles and through the bloodstream. Oxidative modification of self antigens triggers autoimmunity, and the degree of such modification of serum proteins shows striking correlation with disease activity and organ damage in SLE. In T cells from patients with SLE and animal models of the disease, glutathione, the main intracellular antioxidant, is depleted and serine/threonine-protein kinase mTOR undergoes redox-dependent activation. In turn, reversal of glutathione depletion by application of its amino acid precursor, N-acetylcysteine, improves disease activity in lupus-prone mice; pilot studies in patients with SLE have yielded positive results that warrant further research. Blocking mTOR activation in T cells could conceivably provide a well-tolerated and inexpensive alternative approach to B-cell blockade and traditional immunosuppressive treatments. Nevertheless, compartmentalized oxidative stress in self-reactive T cells, B cells and phagocytic cells might serve to limit autoimmunity and its inhibition could be detrimental. Antioxidant therapy might also be useful in ameliorating damage caused by other treatments. This Review thus seeks to critically evaluate the complexity of oxidative stress and its relevance to the pathogenesis and treatment of SLE.

  • Metabolic aberrations induced by mitochondrial abnormalities are linked to self-reactive and inflammatory phenotypes in autoimmune conditions including SLE and rheumatoid arthritis.

    “In various cell types, metabolic aberrations induced by mitochondrial abnormalities are linked to self-reactive and inflammatory phenotypes in autoimmune conditions, including SLE and RA68,69”

    From The role of mitochondria in rheumatic diseases (2022) · cites this paper as [68]

    The sections on diminished antioxidant defences and oxidative autoantigenesis link mitochondrial dysfunction and oxidative stress in SLE to autoreactivity and inflammation. The section on increased mitochondrial ROI production also associates a mitochondrial-protein variant with predisposition to RA, but it does not establish the claimed link to self-reactive or inflammatory phenotypes in RA.

  • These oxidative events can generate neoantigens that the adaptive immune system may recognize as exogenous threats.

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.
