Crystalline killer: the molecular cascade of silica toxicity from inflammation to fibrosis.
Level 5 - mechanism / opinion, no new human data
Narrative review synthesizing molecular mechanisms without a systematic search or original human data

What was done
Narrative review synthesizing the literature on the molecular mechanisms of crystalline silica-induced lung injury and fibrosis, focusing on biological reactivity, inflammatory cascades, and translational biomarkers.
What was found
The abstract reports qualitative mechanistic pathways without quantitative data or effect sizes. Silica deposition drives lysosomal rupture, oxidative stress, NLRP3 inflammasome activation, programmed cell death, and neutrophil extracellular trap formation. These processes trigger chronic inflammation, epithelial-mesenchymal transition, and fibroblast activation, amplified by damage-associated molecular patterns and exosomal microRNAs.
Why it matters
Synthesizes the cellular mechanisms underlying the resurgence of silicosis in industries such as engineered stone fabrication, highlighting potential biomarkers and targets for earlier clinical intervention.
Limits
As a narrative review, it lacks a systematic literature search methodology, risk-of-bias assessment, or original empirical data. No specific sample sizes, study counts, or quantitative metrics are reported in the abstract.
