Necroptosis and RIPK1-mediated neuroinflammation in CNS diseases

Abstract

Apoptosis is crucial for the normal development of the nervous system, whereas neurons in the adult CNS are relatively resistant to this form of cell death. However, under pathological conditions, upregulation of death receptor family ligands, such as tumour necrosis factor (TNF), can sensitize cells in the CNS to apoptosis and a form of regulated necrotic cell death known as necroptosis that is mediated by receptor-interacting protein kinase 1 (RIPK1), RIPK3 and mixed lineage kinase domain-like protein (MLKL). Necroptosis promotes further cell death and neuroinflammation in the pathogenesis of several neurodegenerative diseases, including multiple sclerosis, amyotrophic lateral sclerosis, Parkinson disease and Alzheimer disease. In this Review, we outline the evidence implicating necroptosis in these neurological diseases and suggest that targeting RIPK1 might help to inhibit multiple cell death pathways and ameliorate neuroinflammation. Necroptosis is a form of cell death mediated by receptor-interacting protein kinase 1 (RIPK1), and is observed in several CNS disorders. Here, Yuan, Amin and Ofengeim give an overview of necroptosis in the CNS and explain its relationship with inflammation in CNS disorders.

  • Increased activation of TNF/TNFR1 signalling following chronic activation of microglia can give rise to TNF-mediated necroptotic neuronal cell death, representing a possible therapeutic target in Parkinson's disease.

    “Increased activation of TNF/TNFR1 signalling following chronic activation of microglia can give rise to TNF-mediated necroptotic neuronal cell death, 160 which represents a possible therapeutic target in Parkinson's disease.161”

    From The role of gut dysbiosis in Parkinson’s disease: mechanistic insights and therapeutic options (2021) · cites this paper as [161]

    The Introduction describes TNFR1-triggered necroptosis, and the section on mitochondrial and lysosomal defects reports evidence implicating necroptosis in Parkinson’s disease, including protective effects of RIPK1 inhibition in disease models (page numbers unavailable). The copy does not establish the claimed sequence in Parkinson’s disease—chronic microglial activation increasing TNF/TNFR1 signalling and thereby causing necroptotic neuronal death. Its discussion of chronic microglial inflammation and TNF concerns Alzheimer’s disease. (LLM, conf=0.84)

  • Several neuroinflammation genes, such as RIPK1, are seen specifically in microglial states associated with COVID-19.

    “Yet, several genes that have been implicated in neuroinflammation38 (such as RIPK1) were seen specifically in microglial states associated with COVID-19.”

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.
