Abstract

The inhalation of airborne pollutants, such as asbestos or silica, is linked to inflammation of the lung, fibrosis, and lung cancer. How the presence of pathogenic dust is recognized and how chronic inflammatory diseases are triggered are poorly understood. Here, we show that asbestos and silica are sensed by the Nalp3 inflammasome, whose subsequent activation leads to interleukin-1β secretion. Inflammasome activation is triggered by reactive oxygen species, which are generated by a NADPH oxidase upon particle phagocytosis. (NADPH is the reduced form of nicotinamide adenine dinucleotide phosphate.) In a model of asbestos inhalation, Nalp3 –/– mice showed diminished recruitment of inflammatory cells to the lungs, paralleled by lower cytokine production. Our findings implicate the Nalp3 inflammasome in particulate matter–related pulmonary diseases and support its role as a major proinflammatory “danger” receptor.

  • The paper relies on this without support.

    The mouse model of asbestos inhalation reflects the human pulmonary inflammatory response sufficiently to infer human disease mechanisms.

    “To investigate the in vivo significance of the Nalp3 inflammasome in asbestos-induced inflammation, Nalp3 -/-and Nalp3 +/+ littermate mice were exposed for 9 days to chrysotile asbestos and markers of injury, inflammation and cytokine production were analysed on day 10.”
    “Our findings support the implication of the Nalp3 inflammasome in pulmonary inflammatory diseases that are linked to pathogenic air pollutants and can ultimately lead to lung cancer and fibrosis.”
  • The paper relies on this without support.

    The in vitro concentrations and exposure durations of asbestos and silica used in cell culture are relevant to human exposures.

    “THP1 cells were stimulated for 6 h with the indicated amounts (mg/ml media) of asbestos, silica, diesel exhaust particles (DEP), cigarette smoke extract (CSE, in % solution) and MSU.”
    “Primary human monocyte-derived macrophages also produced mature IL-1β after stimulation with asbestos or silica (Fig. 1C)”
  • The paper relies on this without support.

    Nalp3-deficient mice lack Nalp3 inflammasome function without compensatory developmental or immunological alterations that affect the measured outcomes.

    “Nalp3 -/-and Nalp3 +/+ littermate mice were exposed for 9 days to chrysotile asbestos and markers of injury, inflammation and cytokine production were analysed on day 10.”
    “However, significantly fewer cells were recruited to the lungs of Nalp3 -/- mice after exposure to asbestos (Fig. 4A).”
  • The paper relies on this without support.

    The inhibitors used (cytochalasin D, latrunculin A, KCl, NAC, APDC, DPI, apocynin, deferoxamine, uricase) act specifically on their intended targets without off-target effects that explain the results.

    “Cytochalasin D inhibited not only secretion of mature IL-1β by asbestos (Fig. 3C), but also by the particulate MSU, while for non-crystalline Nalp3 activators such as R837 and nigericin, IL-1β secretion was not affected (Fig. 3C).”
    “IL-1β production was indeed impaired in response to asbestos, MSU and ATP when using these inhibitors (Fig. 3D), suggesting that ROS production was a necessary step in inflammasome activation.”
  • The paper relies on this without support.

    THP1 cells and primary human monocyte-derived macrophages respond to particulate stimulation in a way that represents human alveolar macrophages in vivo.

    “We indeed observed that the macrophage-like cell line THP1 secreted mature IL-1β upon stimulation with asbestos or silica (Fig. 1A).”
    “Primary human monocyte-derived macrophages also produced mature IL-1β after stimulation with asbestos or silica (Fig. 1C)”

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.

A language model drew the claims from the paper on 2026-10-07, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-07 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

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.
