  • Publication year: 2024
  • DOI: 10.1038/s41467-024-54174-5
  • Metadata source: crossref-doi (confidence: high)
  • Original local title: Mechanics-activated fibroblasts promote pulmonary group 2 innate lymphoid cell plasticity propelling silicosis progression

Ingest Mode

  • Mode: focused manual crystallization mode
  • Meaning: this source page was upgraded during focused manual crystallization batch 3 and can support durable synthesis when claims stay source-linked.
  • Required boundary: preserve species, tissue, assay, model, perturbation, and confidence labels when reusing claims.

Source Type

  • primary pulmonary fibrosis/silicosis mechanism study
  • crystallization status: manually promoted into focused manual crystallization batch 3
  • Batch 3 axis: mechanics-activated fibroblast IL-18 drives ILC2 plasticity in silicosis

Evidence Profile

  • Overall confidence: medium-high to high for the source-specific claims listed below; lower for broad extrapolation beyond the reported system.
  • Evidence profile: mechanics-activated fibroblasts, Notch3/caspase-1/IL-18 axis, ILC2-to-ILC1 conversion, pulmonary fibrosis progression.
  • Batch 3 synthesis role: mechanics-activated fibroblast IL-18 drives ILC2 plasticity in silicosis.

Why It Matters Here

This source expands lung ILC2 plasticity beyond asthma and COPD into fibrotic mechanical-niche remodeling.

Key Findings

  • The source reports that ILC2 conversion to ILC1s is involved in silicosis progression.
  • Mechanics-activated fibroblasts promote this conversion through IL-18 in the reported system.
  • Fibroblast Notch3/caspase-1 activity is linked to IL-18 production and pulmonary fibrosis progression.
  • The source strengthens the idea that stromal mechanics can reprogram lung ILC identity.

Claim-Level Confidence

  • High confidence: the source supports a fibroblast-mechanics-IL-18 axis that promotes ILC2-to-ILC1-like plasticity in silicosis models.
  • Medium-high confidence: this is highly relevant to pulmonary fibrosis biology, but should not be merged with allergic asthma ILC2 mechanisms without labeling disease context.
  • Low confidence: human silicosis therapeutic claims require independent validation.

Methods and Context

  • Source kind inferred from title/tags/text: primary research article with animal-model evidence.
  • Species or sample frame detected: mouse
  • Tissue or disease context detected: lung/airway, ARDS/lung injury
  • Assay modalities detected from tags: flow cytometry, in vivo model, in vitro assay, genetic or knockout perturbation
  • Use this source page as a knowledge-oriented first pass; confirm experimental design, gating, perturbation, and outcome measures before manuscript-level use.

Caveats

  • This batch crystallization used source text and extracted article context to promote source-specific claims, but detailed figure panels should still be checked before manuscript-level quotation.
  • Preserve disease, tissue, species, and assay boundaries when reusing this source.
  • Do not use this source alone to make broad pan-ILC, pan-asthma, or clinical-treatment claims.

Contradiction and Supersession

  • Contradiction status: not assessed during bulk ingestion.
  • Supersession status: not assessed during bulk ingestion.
