Soluble and particulate Co‐Cr‐Mo alloy implant metals activate the inflammasome danger signaling pathway in human macrophages: A novel mechanism for implant debris reactivity
Open accessAbstract
Immune reactivity to soluble and particulate implant debris remains the primary cause of aseptic inflammation and implant loosening. However, the intracellular mechanisms that trigger immune cells to sense and respond to exogenous nonbiological agents such as metal particles or metal ions released from orthopedic implants remain unknown. Recent studies in immunology have outlined the importance of the intracellular inflammasome complex of proteins in sensing danger/stress signals triggered by nonbiological agents in the cytosol of macrophages. We hypothesized that metal implant debris can activate the inflammasome pathway in macrophages that causes caspase‐1‐induced cleavage of intracellular pro‐IL‐1β into its mature form, resulting in IL‐1β secretion and induction of a broader proinflammatory response. We tested this hypothesis by examining whether soluble cobalt, chromium, molybdenum, and nickel ions and Co‐Cr‐Mo alloy particles induce inflammasome‐ mediated macrophage reactivity. Our results demonstrate that these agents stimulate IL‐1β secretion in human macrophages that is inflammasome mediated (i.e., NADPH‐, caspase‐1‐, Nalp3‐, and ASC‐dependent). Thus, metal ion‐ and particle‐induced activation of the inflammasome in human macrophages provides evidence of a novel pathway of implant debris‐induced inflammation, where contact with implant debris is sensed and transduced by macrophages into a proinflammatory response. © 2008 Orthopaedic Research Society.

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.
