Abstract

Neuroinflammation and neurodegeneration often result from the aberrant deposition of aggregated host proteins, including amyloid‐β, α‐synuclein, and prions, that can activate inflammasomes. Inflammasomes function as intracellular sensors of both microbial pathogens and foreign as well as host‐derived danger signals. Upon activation, they induce an innate immune response by secreting the inflammatory cytokines interleukin (IL)‐1β and IL‐18, and additionally by inducing pyroptosis, a lytic cell death mode that releases additional inflammatory mediators. Microglia are the prominent innate immune cells in the brain for inflammasome activation. However, additional CNS‐resident cell types including astrocytes and neurons, as well as infiltrating myeloid cells from the periphery, express and activate inflammasomes. In this review, we will discuss current understanding of the role of inflammasomes in common degenerative diseases of the brain and highlight inflammasome‐targeted strategies that may potentially treat these diseases.

  • Inflammasomes are cytosolic multiprotein complexes consisting of the cytosolic sensor protein, ASC, and pro-caspase-1.

    “Inflammasomes are cytosolic multiprotein complexes consisting of the cytosolic sensor protein, the adapter apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), and pro-caspase-1.346”

  • Caspase-1 processes pro-IL-18 and pro-IL-1β into active cytokines.

    “Subsequently, caspase-1 will process the biologically inactive pro-IL-18 and pro-IL-1β into active cytokines.”

  • When brain tissue is damaged or stimulated by α-syn or bacteria and their metabolites in the brain, TLR4 is activated on microglia, and then the NF-κB pathway is activated to promote the secretion of proinflammatory factors such as IL-6, IL-1β, and TNF-α; the ultimate outcome is the death of neurons.

  • Fibrillar Aβ amyloids can induce secretion of IL-1β from microglia via the NLRP3 inflammasome.

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.
